The PagWUS-PagCLV3 module regulates shoot meristem maintenance and activity in poplar

Forestry Research
The shoot apical meristem of vascular plants generates all the aboveground organs. During this process, the structure and function of the meristem are maintained by a group of regulatory genes, among which the WUSCHEL (WUS)-CLAVATA3 (CLV3) module plays ...

Regulation of Inflorescence Architecture by Cytokinins

Frontiers in Plant Science, 2014
In flowering plants, the arrangement of flowers on a stem becomes an inflorescence, and a huge variety of inflorescence architecture occurs in nature. Inflorescence architecture also affects crop yield.

Regulation of shoot meristem shape by photoperiodic signaling and phytohormones during floral induction of Arabidopsis

eLife, 2020
Floral transition, the onset of plant reproduction, involves changes in shape and identity of the shoot apical meristem (SAM). The change in shape, termed doming, occurs early during floral transition when it is induced by environmental cues such as ...

Modulation of Arabidopsis and monocot root architecture by CLAVATA3/EMBRYO SURROUNDING REGION 26 peptide [PDF]

, 2015
Plant roots are important for a wide range of processes, including nutrient and water uptake, anchoring and mechanical support, storage functions, and as the major interface with the soil environment.

Three closely linked X‐chromosomal genes potentially control sex determination in Cannabis sativa

New Phytologist, EarlyView.
Summary Sex determination mechanisms in dioecious plants remain poorly understood yet offer an excellent model system to study genetic changes underlying morphological evolution. We investigated the genetic basis of sex determination in Cannabis sativa, combining quantitative trait locus mapping in a segregating population, comparative transcriptomics ...

A Trypsin‐Like Serine Protease ZmNAL1a Fine‐Tunes Maize Floral Transition and Flowering Time

Advanced Science
The floral transition is a crucial phase in flowering plants that initiates reproductive development. Florigen, a key regulator of this transition, is expressed in the leaves and transmits environmental signals by trafficking to the vegetative shoot ...

Mechanical stress contributes to the expression of the STM homeobox gene in Arabidopsis shoot meristems

eLife, 2015
The role of mechanical signals in cell identity determination remains poorly explored in tissues. Furthermore, because mechanical stress is widespread, mechanical signals are difficult to uncouple from biochemical-based transduction pathways.

TSO1 functions in cell division during Arabidopsis flower development [PDF]

, 1997
We describe an Arabidopsis mutant, tso1, which develops callus-like tissues in place of floral organs. The tso1 floral meristem lacks properly organized three cell layers, and the nuclei of these cells are irregular in size and shape.

Defects in leaf epidermis of Arabidopsis thaliana plants with CDKA;1 activity reduced in the shoot apical meristem [PDF]

, 2012
In Arabidopsis thaliana, like in other dicots, the shoot epidermis originates from protodermis, the outermost cell layer of shoot apical meristem. We examined leaf epidermis in transgenic A.
