Actin Isovariant ACT2‐Mediated Cellular Auxin Homeostasis Regulates Lateral Root Organogenesis in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Lateral root (LR) organogenesis is regulated by cellular flux of auxin within pericycle cells, which depends on the membrane distribution and polar localization of auxin carrier proteins. The correct distribution of auxin carrier proteins relies on the intracellular trafficking of these proteins aided by filamentous actin as a track.

Developmental biology of wood formation [PDF]

, 2003
The wood-forming vascular cambium is responsible for the production of a large part of the biomass on this planet. Yet, there is only limited knowledge on how cell proliferation and differentiation in the cambial meristem are regulated.

MATHEMATICAL MODEL OF PHYTOHORMONE REGULATION OF ROOT MERISTEMATIC ZONE FORMATION

Вавиловский журнал генетики и селекции, 2015
The apical meristem located at the root tip of a plant is one of the most convenient objects to study the organization of the stem cell niche. In the root apical meristem, mitotically inactive cells of the quiescent center coexist with intensely dividing

The Medicago truncatula nodule identity gene MtNOOT1 is required for coordinated apical-basal development of the root

BMC Plant Biology, 2019
Background Legumes can utilize atmospheric nitrogen by hosting nitrogen-fixing bacteria in special lateral root organs, called nodules. Legume nodules have a unique ontology, despite similarities in the gene networks controlling nodule and lateral root ...

Interaction Between Actin and Microtubules During Plant Development

Cytoskeleton, EarlyView.
ABSTRACT The dynamic interaction between actin filaments (AFs) and microtubules (MTs) plays a crucial role in regulating key developmental and physiological processes in plant cells, particularly in the formation of specialized cell types with distinct shapes and functions, such as pollen tubes, trichomes, and leaf epidermal cells.

MpANT regulates meristem development in Marchantia polymorpha

Cell Reports
Summary: Meristems are crucial for organ formation, but our knowledge of their molecular evolution is limited. Here, we show that AINTEGUMENTA (MpANT) in the euANT branch of the APETALA2-like transcription factor family is essential for meristem ...

Ultrastructure of cells in an initiating lateral root primordium of Raphanus sativus

Acta Societatis Botanicorum Poloniae, 2015
Lateral root primordia in Raphanus sativus had developed 10 hours after main root decapitation. The primordia consisted of three cell layers — basal layer continuous with the pericycle. The primordia were initiated by activated groups of pericycle cells.

Differential spatial distribution of miR165/6 determines variability in plant root anatomy [PDF]

, 2017
A clear example of interspecific variation is the number of root cortical layers in plants. The genetic mechanisms underlying this variability are poorly understood, partly due to the lack of a convenient model.

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

EFFECT OF ASCORBIC ACID CONCENTRATION ON STRUCTURAL CHARACTERISTICS OF APPICAL MERISTEMS ON in vitro Aloe barbadensis Mill.

Acta Scientiarum Polonorum: Hortorum Cultus, 2014
Ascorbic acid is one of the major metabolite in higher plants cells which is known as effective factor when the cells enter to “S” phase from “G1” phase of cytokinesis.
