Molecular mechanisms which underpin compound leaf development in some legumes have been reported, but there is no previous study on the molecular genetic control of formation Vigna unguiculata (cowpea), an important dryland legume African origin. In most studied species with leaves, class 1 KNOTTED-LIKE HOMEOBOX genes expressed developing primordia sustain morphogenetic activity, allowing dissection and leaflets. Other genes, such as, SINGLE LEAFLET1 Medicago truncatula Trifoliate Solanum lycopersicum, are also implicated regulating patterning. To set pace for in-depth understanding genetics cowpea, we applied RNA-seq whole genome shotgun sequence datasets a spontaneous cowpea unifoliate mutant its trifoliate wild-type cultivar to conduct comparative reference-based gene expression, de novo genome-wide isoform switch, variant analyses between two genotypes. Our results suggest that genomic variants upstream LATE ELONGATED HYPOCOTYL down-stream REVEILLE4, BRASSINOSTERIOD INSENSITIVE1 LATERAL ORGAN BOUNDARIES result down-regulation key components circadian rhythm central oscillator brassinosteroid signaling, resulting leaves brassinosteroid-deficient-like phenotypes. We stated hypotheses will guide follow-up studies expected provide more insights.

Summary Leaves are the main photosynthetic organs in plants, and their anatomy is optimized for light interception gas exchange. Although each species has a characteristic leaf anatomy, which depends on genotype, leaves also show large degree of developmental plasticity. Light temperature regulate development from primordia differentiation to late stages blade expansion. While molecular mechanisms signaling have been mostly studied seedlings, latest years, research focused development. Here, I will describe work carried out environmental regulation Arabidopsis development, comparing between highlighting new discoveries, pointing most exciting open questions.

Pigmentation patterns are ubiquitous in nature. Visually striking pigmentation not only aesthetically appealing, but also crucial to pollinator interaction and plant fitness. The formation of complex floral mainly relies on the spatiotemporal expression R2R3-MYB transcription factors is often associated with certain development programs, such as organ identity, symmetry, which likely provide key information initiate patterning. For a pattern form, at least pair activator inhibitor required, despite their might vary depending system being investigated. regulation involves multiple molecular mechanisms, transcriptional regulation, small RNA, transposon-mediated gene silencing, methylation body. Identifying these regulators can be facilitated by using single-cell spatial transcriptomics well innovative transformation technologies. Moreover, interdependent, current methods describing static. Therefore, more precise quantitative measurements needed elucidate developmental mechanisms underlying flowers.

Leaf morphogenesis is essential for plant growth and development, yet the mechanisms by which viruses induce changes in leaf shape are not well understood. Rice ragged stunt virus (RRSV) infection induces distinct morphological abnormalities rice leaves, including tip curling serrated margins, through unknown pathogenic mechanisms. This study reveals that key regulatory microRNAs (miR164, miR319 miR156) their target genes (CUC, TCP SPL) exhibit entirely opposite expression patterns healthy RRSV-infected indicating a profound impact on network. Significantly, core protein OsCUC1, typically functions forming dimers, shows abnormal peripheral zone of shoot apical meristem under viral infection, leading to disruptions development. OsTCP1 was found dynamically regulate OsCUC1 dimer formation modifying its subcellular localization interacting with OsSPL14 OsSPL17, thereby influencing functions. Genetic OsSPL14/OsSPL17 enhance severity RRSV demonstrating critical involvement strategy. The research uncovers novel mechanism manipulates interactions factors, disrupting delicate balance These findings expand our understanding manipulation host development provide foundation innovative strategies crop resilience.
