Age Effects on Hypocotyl Mechanics [PDF]

PLOS ONE, 2016
Numerous studies deal with composition and molecular processes involved in primary cell wall formation and alteration in Arabidopsis. However, it still remains difficult to assess the relation between physiological properties and mechanical function at the cell wall level.

Environmental Control of Hypocotyl Elongation [PDF]

Annual Review of Plant Biology
The hypocotyl is the embryonic stem connecting the primary root to the cotyledons. Hypocotyl length varies tremendously depending on the conditions. This developmental plasticity and the simplicity of the organ explain its success as a model for growth regulation.

External coincidence model for hypocotyl thermomorphogenesis [PDF]

Plant Signaling & Behavior, 2018
High but nonstressful temperatures profoundly affect plant growth and developmental processes, termed thermomorphogenesis. Thermo-induced hypocotyl elongation is a typical thermomorphogenic trait, which contributes to cooling plant organs. It is known that external light signals and the circadian clock coordinate rhythmic hypocotyl growth.

Hypocotyl Directional Growth in Arabidopsis: A Complex Trait     [PDF]

Plant Physiology, 2012
Abstract The growth direction of the Arabidopsis (Arabidopsis thaliana) etiolated-seedling hypocotyl is a complex trait that is controlled by extrinsic signals such as gravity and touch as well as intrinsic signals such as hormones (brassinosteroid [BR], auxin, cytokinin, ethylene) and nutrient status (glucose [Glc], sucrose).

Hormonal interactions in the control of Arabidopsis hypocotyl elongation [PDF]

, 2000
The Arabidopsis hypocotyl, together with hormone mutants and chemical inhibitors, was used to study the role of auxin iri cell elongation and its possible interactions with ethylene and gibberellin.

Mutual antagonism between auxin and diacylglycerol acyltransferase 2 regulates high-temperature-induced hypocotyl elongation. [PDF]

New Phytol
Proposed model for auxin–DGAT2 crosstalk regulating high‐temperature‐induced hypocotyl elongation. Summary Cell elongation is a fundamental process in plant growth and development, and it is significantly affected by temperature changes. While the signaling mechanisms driving high‐temperature‐induced cell elongation have been extensively studied, the ...

Plant Metabolites Screening Identifies 7-epi-10-Deacetyltaxol Inhibiting Cell Division by Interfering With the Cell Cycle and Microtubule Organization. [PDF]

Adv Sci (Weinh)
In this study, an efficient screening system is developed for plant metabolites to find a compound, 7‐epi‐10‐deacetyltaxol, inhibits tissue elongation. It suppresses plant growth through brassinosteroid and microtubule pathways. It is later applied to animal cells and human tumor organoids, resulting in similar cell division suppression.

Phototropism in Hypocotyls of Radish [PDF]

Plant Physiology, 1986
When etiolated radish (Raphanus sativus var. hortensis f. gigantissimus Makino) hypocotyls were subjected to a continuous unilateral illumination with white fluorescent light (0.1 watt per square meter), the growth rate at the lighted side was strongly inhibited for the first 2 hours, while that at the shaded side showed no change.

phot1 inhibition of ABCB19 primes lateral auxin fluxes in the shoot apex required for phototropism [PDF]

, 2011
It is well accepted that lateral redistribution of the phytohormone auxin underlies the bending of plant organs towards light. In monocots, photoreception occurs at the shoot tip above the region of differential growth.

Gearing Up the Clock of Hypocotyl Growth! [PDF]

Plant Physiology, 2020
To anticipate daily changes imposed by Earth's rotation, organisms from all domains of life have evolved an endogenous 24-h timer with daily rhythmic functions: the circadian clock. In plants, the first organisms where circadian dynamics were observed, the circadian clock processes ...
