Gibberellins and Gravitropism in Maize Shoots [PDF]

Plant Physiology, 1987
[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).

Shoot and root branch growth angle control - the wonderfulness of lateralness. [PDF]

, 2015
The overall shape of plants, the space they occupy above and below ground, is determined principally by the number, length, and angle of their lateral branches.

Gravity sensing and responses in the coordination of the shoot gravitropic setpoint angle

New Phytologist, 2022
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 ...

Sparse panicle1 is required for inflorescence development in Setaria viridis and maize. [PDF]

, 2017
Setaria viridis is a rapid-life-cycle model panicoid grass. To identify genes that may contribute to inflorescence architecture and thus have the potential to influence grain yield in related crops such as maize, we conducted an N-nitroso-N-methylurea ...

Ammonium inhibits primary root growth by reducing the length of meristem and elongation zone and decreasing elemental expansion rate in the root apex in Arabidopsis thaliana.

PLoS ONE, 2013
The inhibitory effect of ammonium on primary root growth has been well documented; however the underlying physiological and molecular mechanisms are still controversial. To avoid ammonium toxicity to shoot growth, we used a vertical two-layer split plate

Multiple roles for membrane-associated protein trafficking and signaling in gravitropism [PDF]

, 2012
Gravitropism is a process that allows plant organs to guide their growth relative to the gravity vector. It requires them to sense changes in their orientation and generate a biochemical signal that they transmit to the tissues that drive organ curvature.

Plant Peptides on the Rise: From Historical Insight to Future Applications

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant peptides constitute a rapidly expanding class of signalling molecules essential to plant physiology, mediating key processes such as development, stress adaptation, and immune responses. This review traces the history of plant peptide research, from the seminal discovery of systemin to the recent identification of non‐canonical peptides (

Regulation of tiller angle by gravity-sensing genes in rice

Crop Journal
Endodermal cells and starch-accumulating amyloplasts are well-known gravity sensors initiating shoot gravitropism in Arabidopsis thaliana. The transcription factors SHR and SGR1 regulate endodermal cell formation, while PGM has been demonstrated to ...
