Summary: This study identified the major components of the proanthocyanidin regulatory network in chickpea and suggested CaPARs as promising targets for genetic engineering to improve agronomic traits. The researchers discovered 119 typical CaMYB encoding genes and two CaR2R3-MYB transcription factors, named CaPAR1 and CaPAR2, which were found to interact with other key regulators in proanthocyanidin biosynthesis. Transgenic expression of CaPARs in a mutant plant also led to complementation of the transparent testa phenotype.

Summary: The key factors for successful germination and emergence of white clover are light, temperature, planting depth, drought, and salt stress. White clover seeds are negatively photoblastic and show differential responses to temperature. Deeper planting depth leads to lower germination rate, and the optimal depth is <= 1 cm. White clover seeds are highly sensitive to drought and salt stress. These findings provide a foundation for achieving successful establishment of white clover stands.

Summary: Phenomics is a valuable technology for high-dimensional phenotyping, but its application in assessing organismal functional sensitivity to global change drivers is limited. In this study, we used Energy Proxy Traits (EPTs) to investigate the response of a marine invertebrate to multiple environmental drivers. We found significant differences in frequency-specific energy levels and complex developmental-stage specific sensitivities. EPTs are a transferrable method for high-dimensional phenotyping and important for assessing biological sensitivity to global change.

Summary: This study reveals that Strigolactones (SLs) are the master regulators of transcriptional memory upon drought in Arabidopsis, and this role is partially mediated by the BES1 transcription factor. SLs play a crucial role in achieving the complete after-effect of drought by modulating the transcription patterns of a large subset of genes, especially those related to abscisic acid metabolism and signaling. Promoter-enrichment analysis identified potential cis- and trans-acting factors involved in the SL-dependent and SL-independent regulation of genes during drought and recovery.

Summary: This study examines the changes in chromatin and gene expression in response to heat stress in tomato. They found that heat stress rapidly alters chromatin structure and leads to the formation of temporary contacts between promoters and enhancers, which drive the expression of genes responsive to heat stress. The researchers also discovered that this spatial reorganization of chromatin requires the transcription factor HSFA1a.

Summary: The use of beneficial microbes to enhance drought stress tolerance in plants remains largely unexplored. In this study, we found that a root endophytic desert bacterium, Pseudomonas argentinensis strain SA190, can improve drought stress tolerance in Arabidopsis. Through transcriptome and genetic analysis, we discovered that SA190-induced root morphogenesis and gene expression are regulated by the plant abscisic acid pathway. Additionally, we demonstrated that SA190 primes target gene promoters in an epigenetic ABA-dependent manner. Furthermore, we applied SA190 priming to alfalfa crops and observed enhanced performance under drought conditions.

Summary: Symbiotic cnidarians, such as corals and anemones, have evolved efficient molecular mechanisms for nutrient distribution and recycling in order to thrive in nutrient-poor ocean environments. Using the sea anemone Aiptasia, researchers have discovered that glucose and the presence of algae induce the up-regulation and relocalization of glucose and ammonium transporters, which are critical for symbiont functioning and organism-wide nitrogen assimilation. These findings provide insight into the molecular mechanisms underlying nitrogen conservation and recycling in symbiotic cnidarians.

Summary: Posttranscriptional regulation of mRNA mediated by m6A has significant impacts on transcriptome regulation in plants. This study provides a comprehensive understanding of the effects of m6A on both short-term and long-term responses to pathogen signaling in Arabidopsis. The results show that m6A-deficient plants exhibit enhanced resistance to bacterial and fungal pathogen infections with altered immune responses. Furthermore, m6A deposition on defense and immunity-related transcripts is specifically coordinated prior to and during pathogen signal flagellin, and correlates with changes in transcript abundance and cleavage.

Summary: We discovered a mechanism in melon where ethylene produced in the carpel is perceived in the stamen primordia through spatially differentially expressed ethylene receptors. The CmEIN3/CmEIL1 ethylene signaling module in stamen primordia activates the expression of CmHB40, a transcription factor that regulates stamen development and organ senescence. Investigation of melon genetic biodiversity revealed an African haplotype associated with bisexual flower development and altered binding of EIN3/EIL1 to the CmHB40 promoter.
