Main conclusionSilicon application at a concentration of 2 mM induced sugarcane resistance to Nigrospora oryzae by upregulating pathogen recognition and defense genes, thus increasing plant metabolic activities and productivity.AbstractSugarcane is an important global food and industrial crop, but numerous pathogens threaten its productivity. Our team recently identified the fungus Nigrospora oryzae as a pathogen affecting sugarcane's growth and productivity. Although silicon supplementation is active against most fungi, it remains unclear if it would enhance the resilience of sugarcane to N. oryzae, and molecular mechanisms underlying this process are yet to be explored. In this study, we explored the effects of four silicon concentrations (control, 1 mM, 2 mM, and 4 mM) on the growth and disease resistance of seedlings of the sugarcane variety ROC22 under fungal stress. Employing an integrative approach combining detailed phenotypic analysis with transcriptomic and metabolomic profiling, we elucidated the underlying molecular mechanisms of silicon's protective effects. Results indicated that optimal concentrations (2 mM) of silicon enhanced disease resistance and significantly improved plant height, root characteristics, and enzymatic activities. Transcriptomic analysis revealed an upregulation of genes (826) involved in pathogen recognition and defensive response, while metabolomic analysis highlighted alterations in metabolic pathways pertinent to stress response. These findings suggest that silicon supplementation could effectively bolster sugarcane's defense against fungal diseases, offering new insights into its role in plant pathology and paving the way for developing more resilient crop varieties.

Abstract ：
Cadmium (Cd) is a highly toxic element that significantly threatens plant growth and human health. Brassinosteroids (BRs) and salicylic acid (SA) are crucial phytohormones involved in plant growth and defense. While the mechanisms by which BRs and SA individually regulate various plant biological processes have been extensively studied, their interaction with Cd in rice (Oryza sativa L.) remains poorly understood. In this study, we demonstrated that SLENDER GRAIN (OsSLG), a BR biosynthesis-related gene, plays a critical role in regulating in rice. Overexpression of OsSLG enhanced Cd tolerance, whereas OsSLG RNA interference (RNAi) lines (OsSLG-Ri) exhibited hypersensitivity to Cd stress. Exogenous BR treatment improved the Cd tolerance of the wild type and rescued the Cd-sensitive phenotype of OsSLG-Ri. Furthermore, OsSLG overexpression significantly reduced reactive oxygen species (ROS) and Cd accumulation, this reduction was attributed to the downregulation of genes involved in Cd absorption and transport, as well as the upregulation of genes associated with Cd detoxification and ROS scavenging. In addition, OsSLG enhanced the photosynthetic capacity and mineral element content in rice plants, improving their ability to cope with Cd stress. Gene expression analysis showed that OsSLG promoted the expression of the SA pathway genes, and phenotypic analysis confirmed that SA positively regulates Cd tolerance in rice. Notably, BR-induced Cd tolerance was diminished in SA biosynthesis-deficient rice plants overexpressing SA hydroxylase genes OsS5H1 and OsS5H2, suggesting that the SA pathway is necessary for BR-mediated Cd tolerance. In conclusion, our findings highlight OsSLG as a key player in elucidating the interplay between BR and SA under Cd stress.

Abstract ：
Climate change induces various environmental stressors that restrict plant processes, thereby limiting overall crop productivity. Plant secondary metabolites (SMs) enable plants to quickly detect a broad array of environmental stressors and respond in accordance to rapidly changing environmental scenarios. Notably, SMs regulate defense signaling cascades and provide defensive functions to safeguard plants against various biotic and abiotic stressors. In this review, we provide an overview of insights into recent advances in types and biosynthetic pathways of SMs. We emphasize the mechanisms of different biotic and abiotic elicitors-induced SMs synthesis and accumulation to regulate defense responses. In addition, SMs-mediated regulation of plant processes act through phytohormones signaling cascades is discussed. Finally, we show that transcriptional factors regulating SMs biosynthesis and associated regulatory networks could be used for creating resilient plants. Overall, this comprehensive review gives insight into recent advances regarding crucial roles of SMs in enhanced resistance and provides new ideas for the development of stress-resistant varieties under current climate change scenarios.

Abstract ：
Brassinosteroids (BRs) and jasmonic acid (JA) are known to be involved in regulating plant responses to cadmium (Cd) stress. However, their specific roles and interaction in this process remain unclear. In this study, we discovered that exogenous BR alleviated Cd-mediated growth inhibition of rice seedlings. Enhanced Cd tolerance was also observed in m107, a BR-overproduction mutant. Phenotypic analysis of genetic materials involved in BR signaling confirmed the positive role of BR in regulating rice response to Cd toxicity. OsDLT, a key component in the BR signaling pathway, was found to be crucial for BR-mediated Cd tolerance. Further analysis demonstrated that activation of the BR pathway reduced the accumulation of Cd and reactive oxygen species (ROS) by modulating the expression of genes associated with Cd transport and ROS scavenging. Interestingly,

Abstract ：
Sorghum mosaic virus (SrMV) is one of the most prevalent viruses deteriorating sugarcane production. Salicylic acid (SA) plays an essential role in the defense mechanism of plants and its exogenous application has been observed to induce the resistance against biotic and abiotic stressors. In this study, we set out to investigate the mechanism by which sorghum mosaic virus (SrMV) infected sugarcane responds to SA treatment in two sugarcane cultivars, i.e., ROC22 and Xuezhe. Notably, significantly low viral populations were observed at different time points (except for 28 d in ROC22) in response to post-SA application in both cultivars as compared to control based on qPCR data. Furthermore, the lowest number of population size in Xuezhe (20 copies/mu L) and ROC22 (95 copies/mu L) was observed in response to 1 mM exogenous SA application. A total of 2999 DEGs were identified, of which 731 and 2268 DEGs were up- and down-regulated, respectively. Moreover, a total of 806 DEGs were annotated to GO enrichment categories: 348 biological processes, 280 molecular functions, and 178 cellular components. GO functional categorization revealed that DEGs were mainly enriched in metabolic processes, extracellular regions, and glucosyltransferase activity, while KEGG annotation revealed that DEGs were mainly concentrated in phenylpropanoid biosynthesis and plant-pathogen interaction suggesting the involvement of these pathways in SA-induced disease resistance of sugarcane in response to SrMV infection. The RNA-seq dataset and qRT-PCR assay showed that the transcript levels of PR1a, PR1b, PR1c, NPR1a, NPR1b, PAL, ICS, and ABA were significantly up-regulated in response to SA treatment under SrMV infection, indicating their positive involvement in stress endorsement. Overall, this research characterized sugarcane transcriptome during SrMV infection and shed light on further interaction of plant-pathogen under exogenous application of SA treatment.

Abstract ：
The calcium (Ca+2) molecules being an important intracellular messenger are involved in various signal transduction mechanisms in plants. Many external stimuli such as drought, cold, heat stress, metalloid stress (copper (Cu), cadmium (Cd), nickel (Ni), and arsenic), flooding, and salinity stress increase the free Ca+2 ions in the cytosol. The H+/Ca+2 antiporters and Ca+2-ATPases actively transport the cytosolic Ca+2 in intracellular organelles or apoplasts. Increase in Ca+2 concentration is sensed by calcium-binding proteins or Ca+2-sensors which lead to activation of CDPKs (Calcium-dependent protein kinases). These CDPKs regulate various genes responsive to stress to show phenotypic responses against stress stimuli. Hormonal signaling and their crosstalk with Ca+2 have been studied extensively but a thorough understanding of Ca+2 in stress tolerance is limited. This review describes the various aspects of Ca+2 involvement in sensing stress stimuli, signal transduction, role against various stress factors (including temperature extreme, salinity, flooding, metalloids, and drought), the role of Ca+2 in the regulation of physiological processes, and Ca+2-ATPase.

Abstract ：
Sugarcane yellow leaf disease severely affects sugarcane production. As a viral disease, the pathogen sugarcane yellow leaf virus can only be transmitted by aphid vectors rather than mechanical means. To understand the sugarcane responses to ScYLV infection, the corresponding transcriptomic profile of ScYLV-infected and ScYLV-free plants were analyzed with RNA-Seq technology. In this study, Melanaphis sacchari was used as the vector to transmit ScYLV to the susceptible sugarcane cultivar CP72-1210 and transcriptome was sequenced as well as differentially expressed genes between disease-infected and non-infected sugarcane plants were investigated. A total of 1,22,593 genes were assembled, of which 1,630 genes were differentially expressed. Among DEGs, 1,622 were upregulated and eight were downregulated that were further annotated with GO, KEGG, KOG, PFAM, SwissProt, and Nr databases. The expression levels of DEGs in the three KEGG pathways, namely endocytosis, PEX protein synthesis, and endoplasmic reticulum stress response to viral protein synthesis were observed. Interestingly, it was found that the yellow leaf virus could induce the formation of autophagosomes by LC3, promoted by ER stress, and may be related to the replication of viral RNA. We tested 63 DEGs in this research. The qRT-PCR results showed that two were downregulated and 45 were upregulated in response to the ScYLV infection. This study will not only offer an overall comprehension of sugarcane responses to ScYLV infection at the gene expression level but also increase the chances to block the transmission of ScYLV for use in further molecular biology techniques and will aid in increasing the resistance of plants against ScYLV.

Abstract ：
Artemisia giraldii Pamp. is an herbaceous plant distributed only in some areas in China. To understand the evolutionary relationship between plastid and mitochondria in A. giraldii, we sequenced and analysed the plastome and mitogenome of A. giraldii on the basis of Illumina and Nanopore DNA sequencing data. The mitogenome was 194,298 bp long, and the plastome was 151,072 bp long. The mitogenome encoded 56 genes, and the overall GC content was 45.66%. Phylogenetic analysis of the two organelle genomes revealed that A. giraldii is located in the same branching position. We found 13 pairs of homologous sequences between the plastome and mitogenome, and only one of them might have transferred from the plastid to the mitochondria. Gene selection pressure analysis in the mitogenome showed that ccmFc, nad1, nad6, atp9, atp1 and rps12 may undergo positive selection. According to the 18 available plastome sequences, we found 17 variant sites in two hypervariable regions that can be used in completely distinguishing 18 Artemisia species. The most interesting discovery was that the mitogenome of A. giraldii was only 43,226 bp larger than the plastome. To the best of our knowledge, this study represented one of the smallest differences between all sequenced mitogenomes and plastomes from vascular plants. The above results can provide a reference for future taxonomic and molecular evolution studies of Asteraceae species.

Abstract ：
Abiotic stressors are major constraints that affect agricultural plant physio-morphological and biochemical attributes, resulting in a loss of normal functioning and, eventually, a severe decline in crop productivity. The co-occurrence of different abiotic stresses, rather than a specific stress situation, can alter or trigger a wide range of plant responses, such as altered metabolism, stunted growth, and restricted development. Therefore, systematic and rigorous studies are pivotal for understanding the impact of concurrent abiotic stress conditions on crop productivity. In doing so, this review emphasizes the implications and potential mechanisms for controlling/managing combined abiotic stresses, which can then be utilized to identify genotypes with combined stress tolerance. Furthermore, this review focuses on recent biotechnological approaches in deciphering combined stress tolerance in plants. As a result, agronomists, breeders, molecular biologists, and field pathologists will benefit from this literature in assessing the impact of interactions between combined abiotic stresses on crop performance and development of tolerant/resistant cultivars.

Abstract ：
Codonopsis pilosula subsp. tangshen is one of the most important medicinal herbs used in traditional Chinese medicine. Correct identification of materials from C. pilosula subsp. tangshen is critical to ensure the efficacy and safety of the associated medicines. Traditional DNA molecular markers could distinguish Codonopsis species well, so we need to develop super or specific molecular markers. In this study, we reported the plastome of Codonopsis pilosula subsp. tangshen (Oliv.) D.Y. Hong conducted phylogenomic and comparative analyses in the Codonopsis genus for the first time. The entire length of the Codonopsis pilosula subsp. tangshen plastome was 170,672 bp. There were 108 genes in the plastome, including 76 protein-coding genes, 28 transfer RNA (tRNA), and four ribosomal RNA (rRNA) genes. Comparative analysis indicated that Codonopsis pilosula subsp. tangshen had an unusual large inversion in the large single-copy (LSC) region compared with the other three Codonopsis species. And there were two dispersed repeat sequences at both ends of the inverted regions, which might mediate the generation of this inversion. We found five hypervariable regions among the four Codonopsis species. PCR amplification and Sanger sequencing experiments demonstrated that two hypervariable regions could distinguish three medicinal Codonopsis species. Results obtained from this study will support taxonomic classification, discrimination, and molecular evolutionary studies of Codonopsis species.
