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).

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.

Cellular and physiological functions of SGR family in gravitropic response in higher plants [PDF]

Journal of Advanced Research
Background: In plants, gravity directs bidirectional growth; it specifies upward growth of shoots and downward growth of roots. Due to gravity, roots establish robust anchorage and shoot, which enables to photosynthesize.

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.

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.

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 ...

Microarray analyses and comparisons of upper or lower flanks of rice shoot base preceding gravitropic bending. [PDF]

PLoS ONE, 2013
Gravitropism is a complex process involving a series of physiological pathways. Despite ongoing research, gravitropism sensing and response mechanisms are not well understood.

Sequence of Key Events in Shoot Gravitropism [PDF]

Plant Physiology, 1984
It has recently been shown that asymmetric acid efflux is closely correlated with the gravitropic curvature of plant shoots and roots. The research reported here addresses whether auxin (IAA) redistribution in shoots is the cause or result of asymmetric acid efflux.When abraded sunflower (Helianthus annuus cv Mammoth) hypocotyls are submerged in 20 ...

Gravitropism in Higher Plant Shoots [PDF]

Plant Physiology, 1981
It has long been known that applied ethylene can redirect the gravitropic response, but only occasionally has it been suggested that ethylene normally plays a role in gravitropism. Two inhibitors of ethylene synthesis [Co(2+) and aminoethoxyvinylglycine (AVG)] and two inhibitors of ethylene action (Ag(+) and CO(2)) were shown to delay the gravitropic ...
