Abstract :
Sugarcane (Saccharum spp. hybrid) is an important C4 crop in the Poaceae family and represents one of the world's most economically significant crops, contributing 80% of global sugar production and 40% of fuel ethanol. Given the increasing demand for sugar and bioenergy, coupled with climate change and limited arable land, the improvement of sugarcane yield has become a pressing necessity. Plant architecture, the morphological characteristics formed during growth and development, is crucial for crop yield. However, the dissection and application of architecture improvement in sugarcane breeding have lagged significantly behind due to the complex genome, narrow genetic background, and long breeding cycles. Recent advances in genome sequencing, genome editing, multi-omics technologies, and artificial intelligence-driven methods hold great promise for sugarcane breeding through architecture improvement in the future. Here, we highlight the sugarcane architecture characteristics crucial for yield and mechanization, propose the ideal plant architecture (IPA) of sugarcane, and discuss the difficulties, opportunities, and strategies for shaping the sugarcane IPA.

Abstract :
Endosomal sorting complex required for transport (ESCRT) is the major membrane remodeling complex, closely associated with endolysosomal repair and hereditary spastic paraplegias (HSP) diseases. Loss of function mutations in the ESCRT-I component UBAP1 causes a rare type of HSP (spastic paraplegia 80, SPG80), while the underlying pathological mechanism is unclear. Here, we found that UBAP1 but not SPG80 causing mutant was efficiently recruited to damaged lysosomes and mediated lysosome recovery. Loss of UBAP1 results in dysfunction of lysosomes, disconnecting mTOR localization on lysosomes, leading to cytoplasmic mTORC1 activation and TFEB dephosphorylation, as confirmed in vitro and in vivo models. Administration of rapamycin, a specific inhibitor of mTORC1, enhances mTOR lysosomal localization and TFEB phosphorylation. This pharmacological intervention effectively attenuated disease progression and restored lysosomal homeostasis in Ubap1 deficiency mice. Our findings reveal UBAP1's role in lysosome regulation and suggest rapamycin may benefit patients with HSP and other motor neuron disorders.

Abstract :
Modern sugarcane cultivars (Saccharum spp.), predominantly derived from Saccharum officinarum and Saccharum spontaneum, exhibit divergent traits in sugar content, yield, and stress tolerance. However, little is known about the spatial transcriptional regulation pattern of the differentially expressed genes (DEGs) among tissues in the two Saccharum species. This study aimed to investigate these genes according to pathways in root, stem, leaf, and flower tissues using comparative transcriptome analysis. A broad range of DEGs, ranging from 24,469 to 34,198, were identified in four tissues from Badila (S. officinarum) and Ledong2 (S. spontaneum) clones. Thirty-one DEGs involved in abscisic acid (ABA) biosynthesis were identified in the root, suggesting differences in ABA content within root tissues between the two clones. In stem tissues, a significant number of upregulated DEGs were associated with cell growth and division, alongside plant-type cell wall organization, while abundant downregulated DEGs were linked to stress-response processes, possibly contributing to heterogeneity in stem morphology and stress responses. In leaf tissues, DEGs related to photosynthesis and photorespiration pathways likely influenced the variation in plant biomass and sucrose content between Badila and Ledong2. Key DEGs, including LHY, PRR7, and GI, associated with circadian rhythms and the photoperiodic pathway, were identified in flower tissues, providing evidence to explain the discrepancy in flowering time between the two clones. Collectively, the differential regulation of genes across four tissues may contribute to illustrating the divergence of agronomic traits and stress responses in both Saccharum species, offering a valuable foundation for the genetic improvement of sugarcane cultivation and stress resilience.

Abstract :
鞘脂类物质是构成植物膜系统的重要组分,在不同的植物细胞和组织中鞘脂的结构和含量分布迥异。鞘脂也是细胞内重要的信号分子,参与调控植物的程序性细胞死亡、气孔开闭、根的生长、花粉发育、植物形态建成和果实成熟与脱落等多个过程。鞘脂代谢紊乱会造成底物或者产物的积累,进而导致植物生长、发育异常。目前植物中鞘脂的研究主要通过突变体表型和鞘脂类物质的含量来评估,缺乏对精密调控网络的研究,因此有较大的研究空白亟待填补。综述了目前参与植物鞘脂代谢过程的鞘脂类物质及其相关的代谢酶类,并分类讨论了鞘脂代谢基因突变体表型和造成突变体表型的潜在原因。

Abstract :
Unlike early land plants, flowering plants have evolved a pollen tube that transports a pair of non-motile sperm cells to the female gametophyte. This process, known as siphonogamy, was first observed in gymnosperms and later became prevalent in angiosperms. However, the precise molecular mechanisms underlying the male-female interactions remain enigmatic. From the landing of the pollen grain on the stigma to gamete fusion, the male part needs to pass various tests: how does the stigma distinguish between compatible and incompatible pollen? what mechanisms guide the pollen tube towards the ovule? what factors trigger pollen tube rupture? how is polyspermy prevented? and how does the sperm cell ultimately reach the egg? Successful male-female communication is essential for surmounting these challenges, with cysteine-rich peptides (CRPs) playing a pivotal role in this dialogue. In this review, we summarize the characteristics of four distinct classes of CRPs, systematically review recent progress in the role of CRPs in four crucial stages of pollination and fertilization, consider potential applications of this knowledge in crop breeding, and conclude by suggesting avenues for future research. A review of the significant roles played by cysteine-rich peptides in reproductive processes, emphasizing the most recent advancements in this field, along with proposed avenues for future research.

Abstract :
Stress is considered as a major cause of depression. C-Jun N-terminal kinase (JNK) is a member of the stress-induced mitogen activated protein (MAP) kinase family which is often activated through phosphorylation. Clinical studies and animal experiments have found that abnormal phosphorylation/activation of JNK exists in the occurrence of various psychiatric diseases. Recently, several studies linked JNK kinase activity to depression. However, whether excessive activation of JNK activity is directly responsible for the occurrence of depression and the underlying mechanisms remain unclear. Here, we constructed a conditional transgenic mouse which is specifically expressing MKK7-JNK1 (CAJNK1) in the central nervous system. CAJNK1 mice showed activation of JNK and lead to depression-like behavior in mice. Transcriptome analysis indicates reduced expression of synaptic-associated genes in CAJNK1 mice brains. Consistently, we found abnormal dendritic spine development and PSD95 downregulation in CAJNK1 hippocampal neurons. Our studies provide compelling evidence that activation of JNK as an intrinsic factor leading to depression-like behavior in mice provides direct clues for targeting the JNK activity as a potential therapeutic strategy for depression.

Abstract :
Sexual reproduction in angiosperms is siphonogamous, and the interaction between pollen tube and pistil is critical for successful fertilization. Our previous study demonstrated that mutation of the Arabidopsis turgor regulation defect 1 (TOD1) gene leads to reduced male fertility, a result of retarded pollen tube growth in the pistil. TOD1 encodes a Golgi-localized alkaline ceramidase, a key enzyme for the production of sphingosine-1-phosphate (S1P), which is involved in the regulation of turgor pressure in plant cells. However, whether TOD1s play a conserved role in the innovation of siphonogamy is largely unknown. In this study, we provide evidence that OsTOD1, which is similar to AtTOD1, is also preferentially expressed in rice pollen grains and pollen tubes. OsTOD1 knockout results in reduced pollen tube growth potential in rice pistil. Both the OsTOD1 genomic sequence with its own promoter and the coding sequence under the AtTOD1 promoter can partially rescue the attod1 mutant phenotype. Furthermore, TOD1s from other angiosperm species can partially rescue the attod1 mutant phenotype, while TOD1s from gymnosperm species are not able to complement the attod1 mutant phenotype. Our data suggest that TOD1 acts conservatively in angiosperms, and this opens up an opportunity to dissect the role of sphingolipids in pollen tube growth in angiosperms.

Abstract :
Sex types of papaya are controlled by a pair of nascent sex chromosomes, but molecular genetic mechanisms of sex determination and sex differentiation in papaya are still unclear. We performed comparative analysis of transcriptomic profiles of male and female floral buds at the early development stage before the initiation of reproductive organ primordia at which there is no morphological difference between male and female flowers. A total of 1734 differentially expressed genes (DEGs) were identified, of which 923 showed female-biased expression and 811 showed male-biased expression. Functional annotation revealed that genes related to plant hormone biosynthesis and signaling pathways, especially in abscisic acid and auxin pathways, were overrepresented in the DEGs. Transcription factor binding motifs, such as MYB2, GAMYB, and AP2/EREBP, were enriched in the promoters of the hormone-related DEGs, and transcription factors with those motifs also exhibited differential expression between sex types. Among these DEGs, we also identified 11 genes in the non-recombining region of the papaya sex chromosomes and 9 genes involved in stamen and carpel development. Our results suggested that sex differentiation in papaya may be regulated by multiple layers of regulation and coordination and involved transcriptional, epigenetic, and phytohormone regulation. Hormones, especially ABA and auxin, transcription factors, and genes in the non-recombination region of the sex chromosome could be involved in this process. Our findings may facilitate the elucidation of signal transduction and gene interaction in sex differentiation of unisexual flowers in papaya.
