Summary Grasses are fundamental to human survival, providing a large percentage of our calories, fuel, and fodder for livestock, an enormous global carbon sink. A particularly important part the grass plant is grain‐producing inflorescence that develops in response both internal external signals converge at shoot tip influence meristem behavior. Abiotic trigger reproductive development vary across family, mostly due unique ecological phylogenetic histories each clade. The time it takes flower has implications its ability escape harsh environments, while also indirectly affecting abiotic stress tolerance, architecture, grain yield. Here, we synthesize recent insights into evolution flowering past climate change, focusing on genetic convergence underlying traits. We then discuss how why rewiring shared ancestral pathway affects yields, outline ways which researchers using this other information breed higher yielding, climate‐proof cereal crops.

In ornamental plants, one of the most complex life processes, i.e., flowering, is regulated by interaction between microbiota, hormones, and genes. Flowering plays an integral role in overall development quintessential for reproduction. Considering its importance, this review explores mechanisms that determine induction highlighting relationship hormonal genetic networks as well growing significance microbiome. Important genes involved control include FT, SOC1, LFY. These react to environmental stimuli like photoperiod vernalization. Auxins, cytokinin, gibberellins are only a few hormone pathways important floral growth timing. The importance plant-microbe interactions has been emphasized current research, which shows microbiome affects flowering through processes production availability food. A comprehensive understanding possible integrating results from genetics studies, may improve breeding culture plants. For researchers understand complexity plants develop unique strategies improved qualities, it critical use interdisciplinary approaches, investigation demonstrates.

Human nutrition is inherently associated with the cultivation of vegetables, grains, and fruits, underscoring critical need to understand manipulate balance between vegetative reproductive development in plants. Despite vast diversity within plant kingdom, these developmental processes share conserved interconnected pathways among angiosperms, predominantly involving age, vernalization, gibberellin, temperature, photoperiod, autonomous pathways. These interact environmental cues orchestrate transition from growth stages. Related this, there are two key genes belonging same Phosphatidylethanolamine-binding proteins family (PEBP), FLOWERING LOCUS T (FT) TERMINAL FLOWER 1 (TFL1), which activate repress floral initiation, respectively, different species. They compete for transcription factors such as D (FD) 14-3-3 form activation complexes (FAC) repression (FRC). The FT/TFL1 mechanism plays a pivotal role meristem differentiation, determining outcomes determinate or indeterminate. This review aims explore roles FT TFL1 architecture induction annual perennial species, together their interactions hormones. In this context, we propose that can be modulated by response and/or regulators (PGRs), emerge potential tools mitigating adverse effects changes on processes. Thus, understanding mechanisms crucial address challenges agricultural practices, especially face climate change.

Abstract Plants face the most diverse climatic conditions throughout their life cycle. As sessile organisms, they are remarkably resilient to adverse environments, which have been exacerbated in current context of global change. The way plants sense and respond various types abiotic stresses varies depending on severity stress developmental stage plant, affecting both vegetative reproductive aspects. Understanding how adapt a changing environment is crucial for predicting mitigating impacts climate change ecosystems ensuring future survival reproduction plant species.

Abstract Variation in shoot architecture, or tillering, is an important adaptive trait targeted during the domestication of crops. A well-known regulatory factor architecture TEOSINTE BRANCHED 1 (TB1). TB1 and its orthologs have a conserved function integrating environmental signals to regulate axillary branching, tillering cereals. The barley ortholog TB1, VULGARE ROW-TYPE SIX 5 (VRS5) does not only but also involved regulating row-type by inhibiting lateral spikelet development. These discoveries predominantly come from genetic studies, how VRS5 regulates these processes on molecular level remains largely unknown. By combining transcriptome analysis between vrs5 wild type at different developmental stages DAP-sequencing locate genome-wide DNA binding sites VRS5, we identified bona fide targets VRS5. We found that abscisic acid related genes, potentially inhibit way. While later inflorescence development, gene VRS1 several known floral development like MIKCc MADS-box are targeted. This study identifies significant genes for mutational analysis, representing selection will contribute deeper understanding network role shaping

Auxin response factors(ARFs) are a class of transcription factors that regulate the expression auxin genes and play crucial role in plant growth development. Florigen plays process flowering. However, by which regulates accumulation florigen remains largely unclear. This study found ZmARF16 maize increases during flowering, genetic transformation accelerates flowering Arabidopsis maize. Furthermore, was to be positively correlated with ZCN12 gene. Similarly, FT-like gene rescues late phenotype FT mutation Arabidopsis. Moreover, actively participates process. Further research revealed responds signal, interaction between promoter, as well subsequent promotion expression, leads early confirmed through yeast one-hybrid dual-luciferase assay. Therefore, provides evidence ZmARF16-ZCN12 module regulating

The determinate growth habit of plants reduces the number internodes and shortens main stem by terminating shoot apical meristem through a transition to inflorescence. Understanding genetic basis this can help optimize crop yield cultivation technology for vegetable breeding. This study aimed identify determinate-2 (de-2) gene responsible in W-sk cucumber line. Termination line occurred between 14 23 internodes, depending on conditions. Resequencing genome identified novel SNP TERMINAL FLOWER1 (CsTFL1) gene, explaining de-2 phenotype. was verified with CAPS-T marker cosegregation F

Bamboo plants have erratic flowering habits with a long vegetative growth and an uncertain cycle. The process of floral transition has always been one the hot intriguing topics in bamboo developmental biology. As master modulators gene expression at post-transcriptional level, miRNAs play crucial role regulating reproductive growth, especially plants.
