The ASH1-RELATED3 SET-domain protein controls cell division competence of the meristem and the quiescent center of the Arabidopsis primary root.
The stem cell niche of the Arabidopsis (Arabidopsis thaliana) primary root apical meristem is composed of the quiescent (or organizing) center surrounded by stem (initial) cells for the different tissues. Initial cells generate a population of transit-amplifying cells that undergo a limited number of cell divisions before elongating and differentiating. It is unclear whether these divisions occ...
متن کاملAllelopathy and Anti-mitotic Effects of Cuscuta campestris and Cuscuta monogyna Extracts on Plant Cell Division
Some natural compounds of plants including phenols and alkaloids induce mitosis depressive that are blocked cell division. Field dodder (Cuscuta campestris Yunck.) and eastern dodder (Cuscuta monogyna Vahl.) are the most widespread obligatory parasitic species. In the present study, end of summer 2015, field dodder and eastern dodder are collected from Alhagi maurorum Medik. host and Vine (Viti...
متن کاملThe folylpolyglutamate synthetase plastidial isoform is required for postembryonic root development in Arabidopsis.
A recessive Arabidopsis (Arabidopsis thaliana) mutant with short primary roots and root hairs was identified from a forward genetic screen. The disrupted gene in the mutant encoded the plastidial isoform of folylpolyglutamate synthetase (FPGS), previously designated as AtDFB, an enzyme that catalyzes the addition of glutamate residues to the folate molecule to form folylpolyglutamates. The shor...
متن کاملQuiescent center initiation in the Arabidopsis lateral root primordia is dependent on the SCARECROW transcription factor.
Lateral root formation is an important determinant of root system architecture. In Arabidopsis, lateral roots originate from pericycle cells, which undergo a program of morphogenesis to generate a new lateral root meristem. Despite its importance for root meristem organization, the onset of quiescent center (QC) formation during lateral root morphogenesis remains unclear. Here, we used live 3D ...
متن کاملFramework for gradual progression of cell ontogeny in the Arabidopsis root meristem.
In plants, apical meristems allow continuous growth along the body axis. Within the root apical meristem, a group of slowly dividing quiescent center cells is thought to limit stem cell activity to directly neighboring cells, thus endowing them with unique properties, distinct from displaced daughters. This binary identity of the stem cells stands in apparent contradiction to the more gradual c...
