Summary: Shading delays flowering and reduces reproductive growth in alfalfa, leading to lower pollen viability and stigma receptivity, as well as reduced quantity and quality of seeds. However, delayed flowering and reduced reproduction are important strategies for alfalfa to cope with shading.

Summary: This study constructs the full-length transcriptome of Alfalfa root and elucidates its molecular mechanism under drought stress. The results reveal 2615, 6011, and 4617 DEGs in three comparisons, with enrichment of ribosome, glutathione metabolism, and biosynthesis of amino acids. The majority of DEGs belong to AP2/ERF-ERF (37), C2H2 (32), and bHLH (22) bZIP (22) transcription factors. Additionally, 24 genes related to ABA and auxin hormone signaling pathway are identified.

Summary: In this study, an NF-YC2 gene was identified in alfalfa and its role in enhancing alkaline adaptation abilities in alfalfa was explored. Transgenic plants with overexpression of MsNF-YC2 exhibited higher levels of antioxidant enzyme activities and proline levels, as well as reduced levels of hydrogen peroxide and superoxide anion. Transcriptomic analysis revealed that MsNF-YC2 overexpression regulated the expression of genes related to plant hormone signal transduction and photosynthesis.

Summary: This article describes two strategies to induce dominant mutations in the M. sativa genome and discusses their relevance in controlling flowering time. The first strategy involves genome engineering using microProteins as developmental regulators, while the second strategy involves inducing point mutations to uncouple gene regulation by microRNAs.

Summary: This study analyzed the expression of CaHSP18.1a in heat-sensitive and heat-tolerant pepper lines, demonstrating a strong and early response to heat, salt, and drought stresses. Silencing CaHSP18.1a reduced resistance in pepper plants, while overexpressing it in transgenic Arabidopsis increased resistance to these stresses. The protein CaHSP18.1a was found to be localized to the cell membrane, suggesting its role as a positive regulator in response to abiotic stresses.

Summary: Glutathione transferases (GSTs) are an ancient, ubiquitous, multi-functional antioxidant enzyme superfamily that play a crucial role in cellular detoxification and plant development. Through genome-wide identification, it was found that Medicago truncatula has ninety-two putative MtGST genes coding for 120 proteins, classified into twelve classes. Expression profiling showed high organ/tissue-specific expression, with certain members significantly up-regulated in response to stresses. Among stress-responsive members, MtGSTU17 exhibited strong substrate affinity and conserved binding site residues. These findings will aid in further understanding the function and evolution of GST genes in Medicago.

Summary: The NF-Y gene family plays an important role in plant growth, development, and stress responses. This study identified 64 members of the NF-Y gene family in the Medicago sativa genome and found that these genes were significantly induced or downregulated by alkali treatment. These findings provide a basis for further research on the function of NF-Y genes in Medicago sativa and other legume species.

Summary: Flowering time is an important trait for hemp, impacting yields and quality. This study identified the genetic differences in flowering time within and across cultivars, as well as the recessive trait of photoperiod insensitivity in some cultivars known as autoflowering. The study successfully mapped the loci responsible for autoflowering and flowering time, and developed molecular marker assays for breeder-friendly use.

Summary: Members of the SWEET family play important roles in sugar transport, plant growth, and development. This study explored the SWEET family in pomegranate and discovered the effects of tripotassium phosphate and plant exogenous hormone treatments on the expression patterns of PgSWEETs. The findings provide valuable insights for further functional verification and regulation of sugar metabolism pathways in PgSWEETs.

Summary: This study identified and characterized a key regulatory module PvSPL6 in switchgrass, which plays a critical role in controlling flowering and growth development. PvSPL6 was found to localize in both the plasma membrane and nucleus, and overexpression or downregulation of PvSPL6 affected the flowering and growth of switchgrass. The study also demonstrated that PvSPL6 can rapidly transport between the nucleus and the plasma membrane in response to GA(3) treatment.

Summary: Phospholipase D plays a crucial role in regulating rice heading time, with overexpression of secretory spPLD delaying heading time and suppression or deficiency leading to early heading. The study also revealed the binding of rice Hd3a and RFT1 to phosphatidylcholines and altered phospholipid profiles in shoot apical meristem under different spPLD expressions.

Summary: This study identified 58 ZmSBT genes from the maize genome and conducted a comprehensive investigation of their characteristics. The analysis showed that ZmSBTs have conserved functions and are expressed in different tissues and in response to specific stress. The study also revealed the specific expression pattern of ZmSBTs during maize anther development and their subcellular localization.

Summary: In this study, 14 MsWOX transcription factors were identified and analyzed in cultivated alfalfa cv. Zhongmu No.1. The MsWOX genes were found to have tissue-specific expression patterns and respond differently to plant hormones and abiotic stress. The study provides valuable insights into the roles of MsWOX transcription factors in developmental processes and abiotic stress responses in alfalfa.
