Summary: This study dissected the genetic architecture of plasticity in response to different nitrogen levels in Arabidopsis thaliana accessions. It was found that plasticity in levels of primary metabolites were related to the plasticities of the studied traits, and the gene At1g19880 was identified to confer plasticity of rosette diameter in response to nitrogen. Additionally, different genetic programs were shown to regulate growth and flowering-related traits in response to environmental cues.

Summary: The study found that in Arabidopsis, the ethylene signaling transcription factors EIN3 and EIL1 are involved in SA-induced leaf senescence, and ET enhances the effect of SA in promoting senescence, NPR1 interacts with EIN3 to promote its transcriptional activity. This suggests that SA and ET work together in senescence, in contrast to their antagonistic crosstalk in other biological processes.

Summary: Our study revealed different genetic architectures in response to Ralstonia solanacearum hpaP mutant in two Arabidopsis thaliana mapping populations, with a delayed global response compared to wild-type strain. We identified several quantitative trait loci associated with the hpaP mutant inoculation, with genes involved in specific biological processes important for R. solanacearum virulence. Focusing on four candidate genes identified using a worldwide collection, we validated three of them as susceptibility factors.

Summary: The transcription factor ERF34 plays a crucial role in leaf senescence by modulating the expression of senescence-inducing genes and promoting salt stress tolerance. ERF34 is differentially expressed under various leaf senescence-inducing conditions and negatively regulates leaf senescence induced by age, dark, and salt stress. ERF34 directly binds to and activates the expression of salt stress-responsive genes.

Summary: APX6 is identified as a senescence-associated gene specifically induced in aging leaves and in response to senescence-promoting stimuli. Mutants of apx6 exhibit early developmental senescence and increased sensitivity to dark stress. Age-dependent post-transcriptional regulation of APX6 and its potential interaction with miR398 and copper redistribution pathways are important for ROS/redox homeostasis and signaling in aging leaves.

Summary: The study found that FHY3 and FAR1 interact with and repress the DNA binding activity of EIN3 and PIF5, leading to the coordinated regulation of leaf senescence. Decreased accumulation of FHY3 protein during aging or under dark conditions lifts its repression on EIN3 and PIF5, resulting in increased ORE1 expression and onset of leaf senescence. FHY3 and FAR1 act as an age gating mechanism integrating light and ethylene signaling to prevent precocious leaf senescence.

Summary: This study demonstrates that MIR840 negatively regulates gene expression by promoting target mRNA cleavage and impairing translation, particularly affecting plant senescence through the targeting of PPR and WHY3 genes. Knockdown of both PPR and WHY3 in wild-type plants resulted in a senescence phenotype resembling that of the MIR840-overexpressing plant, indicating their crucial role in the MIR840-mediated senescence pathway.

Summary: The study investigated the metabolic properties of 208 soybean mutant diversity pool (MDP) lines by measuring the isoflavone and fatty acid contents of the seed. Differences in gene expression patterns were observed among individuals and wild-types at different stages, with six lines showing altered isoflavone content and six lines showing altered oleic acid content selected for further analysis. The results provide insights into the regulatory genes involved in the isoflavone and fatty acid biosynthetic pathways in soybean.

Summary: This study investigated the natural selection and genetic architecture of flowering time in Arabidopsis through field experiments in Europe. It found associations between loci related to flowering time and climate adaptation. The results showed selection for early flowering and increased stability, but little detection of plasticity. Genome-wide association studies identified significant associations with flowering traits and supported polygenic inheritance. The association of late flowering genotypes and alleles with climate presented evidence of past adaptation. However, current selection favored rapid flowering in agricultural settings.

Summary: Leaf senescence is regulated by a complex network of genes. In this study, the researchers developed a cellular approach using transient expression in Arabidopsis protoplasts to examine the functional roles of senescence regulatory genes. They validated this system and found that it can effectively monitor the expression of senescence-responsive genes. The results provided molecular evidence for the distinct kinetic involvement of these genes in leaf senescence regulation.

Summary: The circadian clock is a timekeeping and homeostatic system that can compensate for variable salt levels in the environment. Our study revealed that the plasma membrane Na+/H+ antiporter SOS1 functions as a salt-specific circadian clock regulator through its interaction with GIGANTEA (GI) in a salt-dependent manner. SOS1 stabilizes the protein level of GI to maintain a proper clock period under saline conditions.

Summary: N6-adenosine methylation is a prevalent form of RNA modification in eukaryotic organisms, and it plays a crucial role in regulating RNA processing and gene expression. In plants, m(6)A methylation has been found to be involved in the regulation of the plant circadian clock, which controls the rhythmic expression of genes in response to environmental changes. Understanding the molecular mechanisms behind m(6)A modification and its role in the circadian clock will contribute to a greater understanding of plant biology.

Summary: In this study, comparative transcriptome analysis was conducted using RNA-sequencing to identify putative genes involved in flower coloration in three kenaf mutants at different flower developmental stages. The expression profiling of the transcripts revealed 1044 differentially expressed genes in the young bud stage and 472 differentially expressed genes in the full bloom stage among the mutants. KEGG enrichment analysis indicated that the representative pathway was biosynthesis of secondary metabolites, including phenylpropanoid biosynthesis and flavonoid biosynthesis. This study provides valuable information for understanding the gene functions of flower coloration in kenaf.

Summary: Flowering time in plants is regulated by various factors including temperature. This study reveals that the transcriptional repressor HOS15 controls flowering time in response to low ambient temperature by regulating the abundance of the GI protein. HOS15 acts as an E3 ubiquitin ligase and transcriptional repressor to coordinate appropriate flowering time in response to ambient environmental conditions such as temperature and day length.
