Jasmonate-regulated root growth inhibition and root hair elongation

Journal of Experimental Botany, 2022
AbstractThe phytohormone jasmonate is an essential endogenous signal in the regulation of multiple plant processes for environmental adaptation, such as primary root growth inhibition and root hair elongation. Perception of environmental stresses promotes the accumulation of jasmonate, which is sensed by the CORONATINE INSENSITIVE1 (COI1)–JASMONATE ZIM-

Auxin/Cytokinin Antagonistic Control of the Shoot/Root Growth Ratio and Its Relevance for Adaptation to Drought and Nutrient Deficiency Stresses

International Journal of Molecular Sciences, 2022
The hormones auxin and cytokinin regulate numerous aspects of plant development and often act as an antagonistic hormone pair. One of the more striking examples of the auxin/cytokinin antagonism involves regulation of the shoot/root growth ratio in which

Melatonin promotes Arabidopsis primary root growth in an IAA dependent manner.

Journal of Experimental Botany, 2021
Melatonin (MT) has been characterized as growth regulator in plants. MT shares tryptophan as the precursor with indole-3-acetic acid (IAA) but the interplay between MT and IAA remains controversial. In this study, we aimed to dissect relationship between

A single bacterial genus maintains root growth in a complex microbiome

Nature, 2020
Plants grow within a complex web of species that interact with each other and with the plant 1 – 10 . These interactions are governed by a wide repertoire of chemical signals, and the resulting chemical landscape of the rhizosphere can strongly affect ...

Root Growth Adaptation to Climate Change in Crops

Frontiers in Plant Science, 2020
Climate change is threatening crop productivity worldwide and new solutions to adapt crops to these environmental changes are urgently needed. Elevated temperatures driven by climate change affect developmental and physiological plant processes that ...

Aluminium is essential for root growth and development of tea plants (Camellia sinensis)

Journal of Integrative Plant Biology, 2020
On acid soils, the trivalent aluminium ion (Al3+) predominates and is very rhizotoxic to most plant species. For some native plant species adapted to acid soils including tea (Camellia sinensis), Al3+ has been regarded as a beneficial mineral element. In

Nitrogen Fertilization Increases Root Growth and Coordinates the Root–Shoot Relationship in Cotton

Frontiers in Plant Science, 2020
The root system plays an important role in the growth and development of cotton, and root growth is closely related to shoot growth, both of which are affected by N availability in the soil.

The root-specific NF-Y family transcription factor, PdNF-YB21, positively regulates root growth and drought resistance by ABA-mediated IAA transport in Populus.

New Phytologist, 2020
Root growth control plays an important role in plant adaptation to drought stress, but the underlying molecular mechanisms of this control remain largely elusive.

Peatland warming strongly increases fine-root growth

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Peatlands store up to two-thirds of the world’s soil carbon, but this carbon may be released under warmer conditions, creating an important climate feedback. The belowground warming response of peatlands is particularly uncertain even though

Brassinosteroids Promote Root Growth in Arabidopsis [PDF]

Plant Physiology, 2003
AbstractAlthough brassinosteroids (BRs) are known to regulate shoot growth, their role in the regulation of root growth is less clear. We show that low concentrations of BRs such as 24-epicastasterone and 24-epibrassinolide promote root elongation in Arabidopsis wild-type plants up to 50% and in BR-deficient mutants such as dwf1-6 (cbb1) and cbb3 ...
