As sessile organisms, plants have evolved sophisticated mechanisms to optimize their growth and development in response fluctuating nutrient levels. Brassinosteroids (BRs) are a group of plant steroid hormones that play critical roles developmental processes as well responses environmental stimuli. Recently, multiple molecular been proposed explain the integration BRs with different signaling coordinate gene expression, metabolism, growth, survival. Here, we review recent advances understanding regulatory BR pathway multifaceted intertwined sensing, signaling, metabolic sugar, nitrogen, phosphorus, iron. Further exploring these BR-related will facilitate crop breeding for higher resource efficiency.

Abiotic and biotic stresses globally constrain plant growth impede the optimization of crop productivity. The phytohormone auxin is involved in nearly every aspect development. Auxin acts as a chemical messenger that influences gene expression through short nuclear pathway, mediated by family specific DNA-binding transcription factors known Response Factors (ARFs). ARFs thus act effectors response translate signals into regulation responsive genes. Since initial discovery first ARF Arabidopsis, advancements genetics, biochemistry, genomics, structural biology have facilitated development models elucidating action their contributions to generating responses. Yet, significant gaps persist our understanding despite these endeavors. Unraveling functional roles regulating stress response, alongside genetic molecular mechanisms, still its nascent phase. Here, we review recent research outcomes on ARFs, detailing involvement leaf, flower, root organogenesis development, well responses corresponding regulatory mechanisms: including patterns, characterization, transcriptional, post-transcriptional post- translational across diverse conditions. Furthermore, delineate unresolved questions forthcoming challenges research.

Panicle exsertion is essential for crop yield and quality, understanding its molecular mechanisms crucial optimizing plant architecture. In this study, the sheathed panicle-I (shp-I) mutant was identified from ethyl methane sulfonate population of sorghum [Sorghum bicolor (L.) Moench] variety Hongyingzi (HYZ). While phenotypically similar to wild type during seedling stage, shp-I exhibits a significantly shorter peduncle internode at heading stage. Cytomorphological analysis revealed reduced parenchyma cell size within mutant's internode. Phytohormonal profiling showed lower levels indole-3-acetic acid higher concentrations brassinosteroid in compared Genetic confirmed that phenotype caused by recessive single-gene mutation. Through bulked segregant sequencing (BSA-seq) genetic mapping, causative locus localized 59.65-59.92 Mb interval on chromosome 10, which contains 28 putative genes. Additionally, gene SbiHYZ.10G230700, encodes BTB/POZ MATH (BPM) domain protein, as candidate gene. Further non-synonymous mutations were located domain, affecting 3D structure protein. summary, study provides new material genes future research into regulation length.

Leaf growth initiates in the peripheral region of meristem at apex stem, eventually forming flat structures. Leaves are pivotal organs plants, serving as primary sites for photosynthesis, respiration, and transpiration. Their development is intricately governed by complex regulatory networks. encompasses five processes: leaf primordium initiation, polarity establishment, size expansion, shaping leaf, senescence. The primordia starts from side cone stem. Under precise regulation a series genes, establishes adaxial-abaxial axes, proximal-distal axes medio-lateral polarity, guides cells to divide differentiate specific direction, finally develops into leaves certain shape size. senescence kind programmed cell death that occurs it last stage development. Each these processes meticulously coordinated through intricate interplay among transcriptional factors, microRNAs, plant hormones.

Abstract Despite the high economic and ecological importance of forests, our knowledge adaptive evolution leaf traits remains very limited. Euphrates poplar (Populus euphratica), which has tolerance to arid environment, evolved four heteromorphic forms, including narrow (linear lanceolate) broad (ovate broad-ovate) leaves on different crowns. Here, we revealed significant functional divergence P. euphratica at physiological cytological levels. Through global analysis transcriptome DNA methylation across tree developmental stages, that gene expression epigenetics differentially regulated key processes involving development adaptation leaves, such as hormone signaling pathways, cell division, photosynthesis.

Recent studies have revealed the physiological roles of glutamate receptor-like channels (GLRs) in Arabidopsis; however, functions GLRs rice remain largely unknown. Here, we show that knockout OsGLR3.4 leads to brassinosteroid (BR)-regulated growth defects and reduced BR sensitivity. Electrophoretic mobility shift assays transient transactivation indicated is downstream target OsBZR1. Further, agonist profile showed multiple amino acids can trigger Ca2+ influx an OsGLR3.4-dependent manner, indicating a -permeable channel. Meanwhile, study internode cells demonstrated OsGLR3.4-mediated flux required for actin filament organization vesicle trafficking.

Abstract Polyploidy occurs frequently in plants and is an important force plant evolution crop breeding. New polyploids face various challenges due to genome duplication subsequent changes epigenetic modifications, nucleus/cell size gene expression. How produce evolutionary novelty remains be understood. In this study, a transcriptome comparison between 21-day-old diploid autotetraploid pak choi seedlings revealed that there are few differentially expressed genes (DEGs), with greater proportion of DEGs downregulated response duplication. Genome-wide DNA methylation analysis indicated the level obviously increased, especially transposable elements (TEs) 1 kb flanking regions, upon doubling. The methylated regions were related 12,857 hypermethylated 8,451 hypomethylated genes, negatively correlated differential across DEGs. Notably, TE increases significantly neighboring non-DEGs rather than those These results shed light on role transcriptional regulation mechanism coping “genome shock” doubling cruciferous plants.
