Pattern formation during de novo assembly of the Arabidopsis shoot meristem [PDF]
, 2007 Most multicellular organisms have a capacity to regenerate tissue after wounding. Few, however, have the ability to regenerate an entire new body from adult tissue. Induction of new shoot meristems from cultured root explants is a widely used, but poorly

Expression of Cell Cycle Genes During Sesbania rostrata Stem Nodule Development
Molecular Plant-Microbe Interactions, 1997 Upon infection of Sesbania rostrata with Azorhizobium caulinodans, nodules are formed on roots and stems. Stem nodules develop from abundantly distributed dormant root primordia.

A blast from the past: Understanding stem cell specification in plant roots using laser ablation
Quantitative Plant Biology, 2023 In the Arabidopsis root, growth is sustained by the meristem. Signalling from organiser cells, also termed the quiescent centre (QC), is essential for the maintenance and replenishment of the stem cells.

microRNA165 and 166 modulate response of the Arabidopsis root apical meristem to salt stress
Communications Biology, 2023 In plants, developmental plasticity allows for the modulation of organ growth in response to environmental cues. Being in contact with soil, roots are the first organ that responds to various types of soil abiotic stress such as high salt concentration ...

The Arabidopsis thaliana checkpoint kinase WEE1 protects against premature vascular differentiation during replication stress [PDF]
, 2011 A sessile lifestyle forces plants to respond promptly to factors that affect their genomic integrity. Therefore, plants have developed checkpoint mechanisms to arrest cell cycle progression upon the occurrence of DNA stress, allowing the DNA to be ...

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.

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 ...

Auxin Metabolism in the Root Apical Meristem [PDF]
Plant Physiology, 2000 Abstract Within the root meristem of flowering plants is a group of mitotically inactive cells designated the quiescent center (QC). Recent work links the quiescent state to high levels of the growth regulator auxin that accumulates in the QC via polar transport. This in turn results in elevated levels of the enzyme ascorbic acid oxidase
