Arabidopsis ROOT UVB SENSITIVE2/WEAK AUXIN RESPONSE1 is required for polar auxin transport [PDF]
, 2010 Auxin is an essential phytohormone that regulates many aspects of plant development. To identify new genes that function in auxin signaling, we performed a genetic screen for Arabidopsis thaliana mutants with an alteration in the expression of the auxin ...

Brassinosteroid-regulated plant growth and development and gene expression in soybean
Crop Journal, 2019 Brassinosteroids (BRs) are endogenous phytohormones that play important roles in regulating plant growth and development. In this study, we evaluated the effects of brassinolide (BL, one of the active BRs) on soybean and identified roles of the hormone ...

Arabidopsis thaliana: A Model for the Study of Root and Shoot Gravitropism [PDF]
The Arabidopsis Book, 2002 For most plants, shoots grow upward and roots grow downward. These growth patterns illustrate the ability for plant organs to guide their growth at a specified angle from the gravity vector (gravitropism). They allow shoots to grow upward toward light, where they can photosynthesize, and roots to grow downward into the soil, where they can anchor the ...

An early secretory pathway mediated by GNOM-LIKE 1 and GNOM is essential for basal polarity establishment in Arabidopsis thaliana [PDF]
, 2015 Spatial regulation of the plant hormone indole-3-acetic acid (IAA, or auxin) is essential for plant development. Auxin gradient establishment is mediated by polarly localized auxin transporters, including PIN-FORMED (PIN) proteins. Their localization and

Interaction with gravitropism, reversibility and lateral movements of phototropically stimulated potato shoots [PDF]
Journal of Plant Research, 2016 Phototropic (PT) and gravitropic (GT) bending are the two major tropic movements that determine the spatial position of potato shoots. We studied PT bending of potato plantlets grown under long-day photoperiods in several prearranged position setups providing different interactions with the GT response.

The chemical NJ15 affects hypocotyl elongation and shoot gravitropism via cutin polymerization [PDF]
Bioscience, Biotechnology, and Biochemistry, 2018 ABSTRACT We previously found a chemical, designated as NJ15, which inhibited both auxin and brassinosteroid responses in dark-grown Arabidopsis. To study its mode of action, we performed a phenotypic screening of NJ15-low-sensitive lines among mutant pools of Arabidopsis.

Brassinosteroid control of shoot gravitropism interacts with ethylene and depends on auxin signaling components [PDF]
, 2013 Premise of the study: To reach favorable conditions for photosynthesis, seedlings grow upward when deprived of light upon underground germination. To direct their growth, they use their negative gravitropic capacity.
