Abstract ：
The root is one of the most important organs that determines the final grain yield in rice. Auxin is essential for root development in plants. Rice auxin response factor7 (OsARF7), belonging to the ARF family, is a key regulator of root development. Here, we show that OsARF7 positively regulates root development via auxin signaling. The osarf7 mutants display a significant decrease in the root number, adventitious root (AR) number and length, and primary root (PR) length, compared with the wild-type. Exogenous NAA treatment significantly suppresses PR length in osarf7 mutants, OsARF7-OE lines, and its wild-type, does not affect the root number of osarf7 mutants, but suppresses the biomass of osarf7 mutants. At the molecular level, OsARF7 is preferentially expressed in the culm, root, and leaf, especially highly expressed in the tips of the PR, AR, root pericycle, and lateral root (LR) primordia; meanwhile, OsARF7 expression is significantly enhanced by exogenous NAA treatment, suggesting that the positive regulatory role of OsARF7 on root development is based on auxin signaling. A series of biochemical and genetic analyses demonstrate that OsARF7 functions upstream of OsCRL1 and acts downstream of OsMADS25 to regulate root development via auxin signaling. To conclude, OsARF7 is a key positive regulatory factor that regulates root development by activating the expression of OsCRL1 via auxin signaling, by which, OsMADS25 positively mediates OsARF7 expression in rice. This work provides valuable insight into the regulatory mechanism controlling root development and a genetic resource for the molecular improvement of root architecture.

Key message203 bZIP members were identified in each G. barbadence and G. hirsutum and GhbZIP017 from the A subfamily was a novel drought-related member in cotton.AbstractThe basic leucine zipper (bZIP) transcription factors are widely distributed in plants, but the evolutionary history is still unclear in allotetraploid Gossypium barbadense and Gossypium hirsutum. In this study, 203 bZIP members were identified in each G. barbadense and G. hirsutum. The bZIP members could be further divided into 13 subfamilies. A total of 227 gene duplication events were discovered in two allotetraploid cotton species and mainly occurred in the cotton ancestor. Furthermore, the bZIP family had a conserved evolutionary history in two allotetraploid cotton species. Meanwhile, the bZIP members had tissue-specific expression levels. Moreover, through the RNA-seq analysis, GhbZIP017 from the A subfamily played an important role in drought stress response. GhbZIP017 was localized in the nucleus and acted as a transcriptional repressor. The expression levels of GhbZIP017 in leaves and roots could be highly induced by drought stress. GhbZIP017 overexpression in Arabidopsis could enhance drought tolerance with a higher survival rate, lower membrane ion leakage, higher SOD and POD activity, lower MDA content, and higher expression levels of some drought-related genes. Overall, these results could help us uncover the evolutionary history of the bZIP members in cotton and provide a candidate gene GhbZIP017 for drought breeding in G. hirsutum.

Abstract ：
Soil salinity severely inhibits rice growth. While the SBP-box gene OsSPL10 is known to negatively regulate salt tolerance, its mechanism remains unclear. Since jasmonate (JA) mediates plant stress responses, we investigated the link between OsSPL10 and JA in rice salt tolerance. Disrupting OsSPL10 reduced the shoot Na+/K+ ratio under salt stress, likely explaining the enhanced tolerance in Osspl10 mutants. As leaves are highly sensitive to Na+ toxicity, maintaining a low Na+/K+ ratio is critical for survival. Notably, ten OsJAZ genes (JA repressors) were upregulated in Osspl10 mutants. We found that OsSPL10 directly suppresses certain OsJAZ genes (including OsJAZ9, known to regulate certain ion transporters), by binding to their promoters. These findings suggest that OsSPL10 negatively modulate salt tolerance via the OsJAZ-mediated JA pathway, maintaining ion homeostasis. This study reveals new molecular mechanisms of rice salinity response, emphasizing the interplay between transcription factors and hormonal signaling.

Abstract ：
Cotton diseases pose a serious threat to yield and fiber quality. Systemic acquired resistance (SAR) is a crucial and prolonged immune response to pathogen infection; yet, its regulatory mechanisms remain poorly understood in cotton. Here, 35 TGACG binding (TGA) transcription factors were identified in Gossypium hirsutum, classifying them into five groups based on phylogenetic analysis, conserved motifs, and gene structures. Among them, GhTGA12, a group II member, emerged as a novel disease-associated transcription factor based on RNA-seq analysis under biotic stress conditions. GhTGA12 encodes a nuclear protein with 11 exons and 10 introns, harboring the conserved TGA-specific domains (bZIP, DOG1, Q1, and Q2). GhTGA12 has transcriptional activation activity through its N-terminal region and could be triggered by Pst DC3000. While GhTGA12-over-expressing Arabidopsis did not exhibit enhanced resistance after a single Pst DC3000 challenge, it showed significantly increased resistance upon Pst DC3000 pretreatment, consistent with SAR activation. These lines also exhibited elevated ROS levels and increased PR expression levels (PR1, PR2, PR5, and GRXS13). Additionally, GhTGA12 physically interacts with GhNPR1, a key regulator of SAR. Collectively, this study identifies GhTGA12 as a critical SAR-positive regulator via ROS signaling, PR gene activation, and GhNPR1 interaction, offering new targets for enhancing disease resistance in cotton.

Abstract ：
High plant density (PD) can differentially impact maize yields depending on cultivar characteristics due to varying responses of canopy structures to high PD, making canopy optimization essential to improve yield. This is especially important for sweet maize, which has received limited attention in dense planting in China. A 2-year (2021-2022) field experiment evaluated the performance of two sweet maize cultivars, MT6855 and YZ7, under three PDs: 4.5, 6.0, and 7.5 plants m-2 (PD1, PD2, and PD3). Results showed that increasing PD significantly boosted fresh ear yield in MT6855 while having minimal effect on YZ7. Notably, fresh ear yield of MT6855 under PD2 increased by 14.8% compared to PD1. As PD increased, both cultivars exhibited greater plant height, ear height, internode length, and leaf spacing, along with reduced internode diameter. Higher densities also decreased leaf width, leaf area, leaf angle, and net photosynthetic rate but significantly increased leaf area index, leaf orientation value, and canopy photosynthetic capacity. MT6855 consistently outperformed YZ7, with shorter leaf length, wider leaf width, lower leaf angle, higher leaf orientation, improved photosynthetic parameters, and higher SPAD (Soil Plant Analysis Development) values. Fresh ear yield was significantly positively correlated with canopy photosynthetic capacity, leaf width, and leaf orientation value and negatively correlated with leaf angle. These findings suggest that the compact cultivar MT6855 with 6.0 plants m-2, optimizes canopy structures and enhances photosynthetic capacity, resulting in higher yields. This research offers practical insights for improving sweet maize yield through strategic cultivar selection and PD, supporting food security and sustainable agriculture in China.

Abstract ：
Drought stress is a major limit on the maize growth and productivity, and understanding the drought response mechanism is one of the important ways to improve drought resistance in maize. However, more drought-related genes and their regulated mechanisms are still to be reported. Here, we identified a novel NAC transcription factor ZmNAC55 in Zea mays and comprehensively investigated the functions of ZmNAC55 under drought stress. ZmNAC55 belonged to the NAP subfamily. ZmNAC55 had a conserved NAC domain in the N-terminal region and a divergent TAR region in the C-terminal region. ZmNAC55 was a nuclear protein, and ZmNAC55 and its TAR region had the transcriptional activation activity. Furthermore, the expression level of ZmNAC55 in leaves could be highly induced by drought stress. ZmNAC55 overexpression in Arabidopsis conferred the drought-sensitive phenotype with higher water loss, lower survival rate, higher membrane ion leakage, and higher expression levels of some drought-related genes. Meanwhile, ZmNAC55 underexpression in maize enhanced drought tolerance with lower water loss, higher survival rate, lower membrane ion leakage and lower expression levels of some drought-related genes. In addition, ZmNAC55 appeared to be very key in regulating ROS production under drought stress. Moreover, ZmNAC55 could activate ZmHOP3 expression by binding to its promoter. A novel working model of ZmNAC55 under drought stress could be found in maize. Taken together, the NAC transcription factor ZmNAC55 could negatively regulate drought stress via increasing ZmHOP3 expression in maize. ZmNAC55 is a promising candidate for improving drought resistance in maize.

Abstract ：
Key message Rice OsSPL11 activates the expression ofGW5Lthrough binding to its promoter and positively regulates grain size. Grain size (GS) is an important determinant of grain weight and yield potential in cereal. Here, we report the functional analysis of OsSPL11 in grain length (GL), grain width (GW), and 1000-grain weight (TGW). OsSPL11 mutant plants, osspl11 lines, exhibited a decrease in GL, GW, and TGW, and OsSPL11-OE lines showed an increase in GL and TGW. Expression analysis revealed that OsSPL11 was located in the nucleus and highly expressed in spikelet hull and young development grains, consistent with its function in determining GS. Further analysis confirmed that OsSPL11 directly activates the expression of GW5L to regulate GS, meanwhile OsSPL11 expression is negatively regulated by OsGBP3. Taken together, our findings demonstrate that OsSPL11 could be a key regulator of affecting GS during the spikelet hull development and facilitate the process of improving grain yield by GS modification in rice.

Abstract ：
The small heat shock proteins (sHSPs) are important components in plant growth and development, and stress response. However, a systematical understanding of the sHSP family is yet to be reported in five diploid Gossypium species. In this study, 34 GlsHSPs, 36 GrsHSPs, 37 GtsHSPs, 37 GasHSPs, and 38 GhesHSPs were identified in Gossypium longicalyx, Gossypium raimondii, Gossypium turneri, Gossypium arboreum, and Gossypium herbaceum, respectively. These sHSP members can be clustered into 10 subfamilies. Different subfamilies had different member numbers, motif distributions, gene structures, gene duplication events, gene loss numbers, and cis-regulatory elements. Besides, the paleohexaploidization event in cotton ancestor led to expanding the sHSP members and it was also inherited by five diploid Gossypium species. After the cotton ancestor divergence, the sHSP members had the relatively conserved evolution in five diploid Gossypium species. The comprehensive evolutionary history of the sHSP family was revealed in five diploid Gossypium species. Furthermore, several GasHSPs and GhesHSPs were important candidates in plant growth and development, and stress response. These current findings can provide valuable information for the molecular evolution and further functional research of the sHSP family in cotton.

Abstract ：
Monovalent cation proton antiporters (CPAs) play crucial roles in ion and pH homeostasis, which is essential for plant development and environmental adaptation, including salt tolerance. Here, 68 CPA genes were identified in soybean, phylogenetically dividing into 11 Na+/H+ exchangers (NHXs), 12 K+ efflux antiporters (KEAs), and 45 cation/H+ exchangers (CHXs). The GmCPA genes are unevenly distributed across the 20 chromosomes and might expand largely due to segmental duplication in soybean. The GmCPA family underwent purifying selection rather than neutral or positive selections. The cis-element analysis and the publicly available transcriptome data indicated that GmCPAs are involved in development and various environmental adaptations, especially for salt tolerance. Based on the RNA-seq data, twelve of the chosen GmCPA genes were confirmed for their differentially expression under salt or osmotic stresses using qRT-PCR. Among them, GmCHX20a was selected due to its high induction under salt stress for the exploration of its biological function on salt responses by ectopic expressing in Arabidopsis. The results suggest that the overexpression of GmCHX20a increases the sensitivity to salt stress by altering the redox system. Overall, this study provides comprehensive insights into the CPA family in soybean and has the potential to supply new candidate genes to develop salt-tolerant soybean varieties.
