Development, 2017 Brassinosteroids (BRs) trigger an intracellular signaling cascade through its receptors BR INSENSITIVE 1 (BRI1), BRI1-LIKE 1 (BRL1) and BRL3. Recent studies suggest that BR-independent inputs related to vascular differentiation, for instance root ...

Control of proliferation in the haploid meristem by CLE peptide signaling in Marchantia polymorpha. [PDF]
PLoS Genetics, 2019 The homeostasis of meristems in flowering plants is maintained by cell-to-cell communication via CLE (CLAVATA3/EMBRYO SURROUNDING REGION-related) peptide hormones.

Salt Stress Affects the Redox Status of Arabidopsis Root Meristems
Frontiers in Plant Science, 2016 We report the redox status (profiles) for specific populations of cells that comprise the Arabidopsis root tip. For recently germinated, 3–5-day-old seedlings we show that the region of the root tip with the most reduced redox status includes the root ...

Functional Modules in the Meristems: “Tinkering” in Action
Plants, 2023 Background: A feature of higher plants is the modular principle of body organisation. One of these conservative morphological modules that regulate plant growth, histogenesis and organogenesis is meristems—structures that contain pools of stem cells and ...

The Plant Cell, 2011 This work shows that the mutation of two cytokinin oxidase/dehydrogenases causes the formation of more and larger flowers and describes a previously undiscovered function of cytokinin in ovule-forming placenta tissue.

Auto‐Downregulation of the Florigen FT Production Prevents Precocious Flowering in Plants
Advanced Science, EarlyView.This study shows that the leaf vein‐expressed FD complexes with the florigen FT to bind DNA motifs in FT promoter, which antagonizes CONSTANS‐mediated FT activation to feedback down‐regulate FT expression. This prevents an excessive induction of FT expression by inductive photoperiods, thereby precluding precocious transition to flowering in ...

Organogenesis at the Shoot Apical Meristem [PDF]
Plants, 2018 Lateral organ initiation at the shoot apical meristem involves complex changes in growth rates and directions, ultimately leading to the formation of leaves, stems and flowers. Extensive molecular analysis identifies auxin and downstream transcriptional regulation as major elements in this process.

The Spatiotemporal Genetic Architecture of Seed Vigor in Upland Cotton
Advanced Science, EarlyView.Leveraging the semi‐automated SeedRanger platform, we profiled the germination kinetics of 356 cotton accessions at a 30‐min interval. This high‐throughput phenomic approach delineated a temporal genetic network comprising 541 stage‐specific loci. Crucially, functional validation identified FLA2 as a pivotal, auxin‐modulated regulator that orchestrates
