Plant Root Architectural Traits Mediate a Trade‐Off Between Suppression and Tolerance of Competitors [PDF]

Ecology and Evolution
Plants' competitive ability involves both suppressing the growth of neighbours (competitive effect) and resisting or tolerating their suppression (competitive response).

Strigolactones regulate rice tiller angle by attenuating shoot gravitropism through inhibiting auxin biosynthesis. [PDF]

Proc Natl Acad Sci U S A, 2014
Significance Shoot gravitropism is a key determinant of tiller angle, one of the most important factors that affect ideal plant architecture and grain yield of cereal crops. Strigolactones (SLs) are newly identified plant hormones that play diverse roles in plant growth and development.

The Role of Brassinosteroids in Shoot Gravitropism     [PDF]

Plant Physiology, 2011
In the current model of gravitropism, negative gravitropic (upward) growth of the shoot of a dicotyledonous plant involves sedimentation of starch-containing plastids (statoliths) in the endodermis (starch sheath). Here we show that high levels of brassinosteroids (BRs) counteract gravitropic growth, while BR deficiency enhances gravitropism ...

LAZY1 controls rice shoot gravitropism through regulating polar auxin transport [PDF]

Cell Research, 2007
Tiller angle of rice (Oryza sativa L.) is an important agronomic trait that contributes to grain production, and has long attracted attentions of breeders for achieving ideal plant architecture to improve grain yield. Although enormous efforts have been made over the past decades to study mutants with extremely spreading or compact tillers, the ...

OsBRXL4 Regulates Shoot Gravitropism and Rice Tiller Angle through Affecting LAZY1 Nuclear Localization [PDF]

Molecular Plant, 2019
Rice tiller angle is a key agronomic trait that contributes to ideal plant architecture and grain production. LAZY1 (LA1) was previously shown to control tiller angle via affecting shoot gravitropism, but the underlying molecular mechanism remains largely unknown.

SHOOT GRAVITROPISM 5 mediates the stomatal response to darkness in Arabidopsis.

Plant Biotechnol (Tokyo)
Stomatal regulation, a multifaceted mechanism enabling plants to adapt to diverse environmental conditions and optimize photosynthesis for survival and growth, is considered crucial in drought stress tolerance research. To further enhance our understanding of stomatal regulation, we investigated the novel transcription factors involved in this process.

Brassinosteroid control of shoot gravitropism interacts with ethylene and depends on auxin signaling components [PDF]

American Journal of Botany, 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.

Gravitropism in Higher Plant Shoots [PDF]

Plant Physiology, 1984
Cross and longitudinal sections were prepared for light microscopy from vertical control plants (Xanthium strumarium L. Chicago strain), free-bending horizontal stems, plants restrained 48 hours in a horizontal position, and plants restrained 48 hours and then released, bending immediately about 130 degrees .

PROG1 acts upstream of LAZY1 to regulate rice tiller angle as a repressor

Crop Journal, 2023
Rice tiller angle, as a component of plant architecture, affects rice grain yield via plant density. However, the molecular mechanism underlying rice tiller angle remains elusive.
