MicroRNA MIR396 regulates the switch between stem cells and transit-amplifying cells in arabidopsis roots [PDF]

, 2015
To ensure an adequate organ mass, the daughters of stem cells progress through a transit-amplifying phase displaying rapid cell division cycles before differentiating.

A leucine‐rich‐repeat receptor‐like kinase SERL1 phosphorylates and stabilizes OsALDH2B1 to promote alkaline tolerance and grain size in rice

Journal of Integrative Plant Biology, EarlyView.
The rice aldehyde dehydrogenase OsALDH2B1 enhances grain size and tolerance to alkaline soil by repressing GRAIN SIZE 3 and activating catalases. SERL1‐mediated phosphorylation stabilizes OsALDH2B1 under stress, establishing a signaling axis that overcomes growth‐defense trade‐offs and provides a direct target for breeding high‐yield, alkaline ...

GAP activity, but not subcellular targeting, is required for Arabidopsis RanGAP cellular and developmental functions [PDF]

, 2015
The Ran GTPase activating protein (RanGAP) is important to Ran signaling involved in nucleocytoplasmic transport, spindle organization, and postmitotic nuclear assembly.

A phosphoinositide map at the shoot apical meristem in Arabidopsis thaliana [PDF]

BMC Biology, 2018
In plants, the shoot apical meristem (SAM) has two main functions, involving the production of all aerial organs on the one hand and self-maintenance on the other, allowing the production of organs during the entire post-embryonic life of the plant. Transcription factors, microRNA, hormones, peptides and forces have been involved in meristem function ...

SlGRF1 mediates gibberellin signaling to control cut‐budding in tomato

Journal of Integrative Plant Biology, EarlyView.
Upon wounding, cytokinin increases to initiate callus formation. Gibberellin enhances this, but later blocks bud formation by suppressing SlGRF1. Wounding‐induced protein SlGRF1 triggers buds via NAM1, EPF4, and ER2. Hormonal shifts control cut‐budding phases.

Meristem Genes in the Highly Reduced Endoparasitic Pilostyles boyacensis (Apodanthaceae)

Frontiers in Ecology and Evolution, 2020
The family Apodanthaceae comprises two genera (Apodanthes and Pilostyles) and 11 endoparasitic species, all of them lacking root and shoot apical meristems, stems, and leaves.

Effect of cytokinins on shoot apical meristem in Nicotiana tabacum [PDF]

Archives of Biological Sciences, 2012
Cytokinins are involved in plant cell proliferation leading to plant growth and morphogenesis. The size, activity and maintenance of the shoot apical meristem (SAM) are defined by a balanced rate of mitotic cell divisions and functional cell ...

Towards an integrated molecular understanding of plant hormones

Journal of Integrative Plant Biology, EarlyView.
This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

Expression Profiles of ANGUSTIFOLIA3 and SHOOT MERISTEMLESS, Key Genes for Meristematic Activity in a One-Leaf Plant Monophyllaea glabra, Revealed by Whole-Mount In Situ Hybridization

Frontiers in Plant Science, 2020
Members of the genus Monophyllaea are unique in that they produce no new organ during the vegetative phase in the shoot; instead, one of the cotyledons grows indeterminately.
