Microtubule reorientation in shoots precedes bending during the gravitropic response of cut snapdragon spikes

Journal of Plant Physiology, 2008
The microtubule reorientation during the gravitropic bending of cut snapdragon (Antirrhinum majus L.) spikes was investigated. Using indirect immunofluorescence methods, we examined changes in microtubule orientation in the cortex, endodermis and pith tissues of the shoot bending zone, in response to gravistimulation.

Changes in starch content in oat (Avena sativa) shoot pulvini during the gravitropic response

Journal of Experimental Botany, 2001
In order to determine if components of the signal transduction pathway are involved in starch metabolism during the gravitropic response, the effects of inhibitors of phosphoprotein phosphatases and protein kinases (OA), and calcium channel blockers (LaCl3), on gravitropic bending and starch levels in gravisensitive node/pulvini of oat shoots were ...

Hormonal Regulation of the Gravitropic Response in Pulvini of Grass Shoots

1985
The gravitropic responses in plants can be visualized most easily in terms of three distinct phases: gravity perception, transduction, and cellular response. The second one, transduction, involves the development of the hormonal asymmetry which has been experimentally verified for both roots and shoots that have been gravistimulated.

Transcription factor OsWRKY72 controls rice leaf angle by regulating LAZY1-mediated shoot gravitropism

Plant Physiology
Abstract Leaf angle is a major trait of ideal architecture, which is considered to influence rice (Oryza sativa) cultivation and grain yield. Although a few mutants with altered rice leaf inclination angles have been reported, the underlying molecular mechanism remains unclear.
