Interaction with gravitropism, reversibility and lateral movements of phototropically stimulated potato shoots [PDF]
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.

Overexpression of the protein phosphatase 2A regulatory subunit a gene ZmPP2AA1 improves low phosphate tolerance by remodeling the root system architecture of maize. [PDF]
Phosphate (Pi) limitation is a constraint for plant growth and development in many natural and agricultural ecosystems. In this study, a gene encoding Zea mays L.

Functionally different PIN proteins control auxin flux during bulbil development in Agave tequilana [PDF]
In Agave tequilana, reproductive failure or inadequate flower development stimulates the formation of vegetative bulbils at the bracteoles, ensuring survival in a hostile environment.

The chemical NJ15 affects hypocotyl elongation and shoot gravitropism via cutin polymerization [PDF]
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.

Cellular and physiological functions of SGR family in gravitropic response in higher plants
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.

An early secretory pathway mediated by GNOM-LIKE 1 and GNOM is essential for basal polarity establishment in Arabidopsis thaliana [PDF]
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

Gibberellins and Gravitropism in Maize Shoots [PDF]
[3H]Gibberellin A20 (GA20) of high specific radioactivity (49.9 gigabecquerel per millimole) was applied equilaterally in a ring of microdrops to the internodal pulvinus of shoots of 3-week-old gravistimulated and vertical normal maize (Zea mays L.), and to a pleiogravitropic (prostrate) maize mutant, lazy (la).

Gravity sensing and responses in the coordination of the shoot gravitropic setpoint angle
SummaryGravity is one of the fundamental environmental cues that affect plant development. Indeed, the plant architecture in the shoots and roots is modulated by gravity. Stems grow vertically upward, whereas lateral organs, such as the lateral branches in shoots, tend to grow at a specific angle according to a gravity vector known as the gravitropic ...
