Phytochrome B represses Teosinte Branched1 expression and induces sorghum axillary bud outgrowth in response to light signals.
Light is one of the environmental signals that regulate the development of shoot architecture. Molecular mechanisms regulating shoot branching by light signals have not been investigated in detail. Analyses of light signaling mutants defective in branching provide insight into the molecular events associated with the phenomenon. It is well documented that phytochrome B (phyB) mutant plants disp...
متن کاملMAX1, a regulator of the flavonoid pathway, controls vegetative axillary bud outgrowth in Arabidopsis.
We show that MAX1, a specific repressor of vegetative axillary bud outgrowth in Arabidopsis, acts a positive regulator of the flavonoid pathway, including 11 structural genes and the transcription factor An2. Repression of bud outgrowth requires MAX1-dependent flavonoid gene expression. As the flavonoidless state leads to lateral outgrowth in Arabidopsis, our data suggest that a flavonoid-based...
متن کاملChange in Auxin and Cytokinin Levels Coincides with Altered Expression of Branching Genes during Axillary Bud Outgrowth in Chrysanthemum
In the production and breeding of Chrysanthemum sp., shoot branching is an important quality aspect as the outgrowth of axillary buds determines the final plant shape. Bud outgrowth is mainly controlled by apical dominance and the crosstalk between the plant hormones auxin, cytokinin and strigolactone. In this work the hormonal and genetic regulation of axillary bud outgrowth was studied in two...
متن کاملRegulation of correlative inhibition of axillary bud outgrowth by basal branches varies with growth stage in Trifolium repens
In Trifolium repens the decline in bud outgrowth that occurs with distance from basal root systems is due to correlative inhibition by the first-formed basal branches. The apical and axillary buds on these basal branches are the source of the inhibitory effect, but their mode of action is unclear. Inhibition might occur via basal branches being a sink for xylem-transported branching stimulants ...
متن کاملGlobal analysis of the sugarcane microtranscriptome reveals a unique composition of small RNAs associated with axillary bud outgrowth
Axillary bud outgrowth determines shoot architecture and is under the control of endogenous hormones and a fine-tuned gene-expression network, which probably includes small RNAs (sRNAs). Although it is well known that sRNAs act broadly in plant development, our understanding about their roles in vegetative bud outgrowth remains limited. Moreover, the expression profiles of microRNAs (miRNAs) an...
