Antagonistic action of strigolactone and cytokinin in bud outgrowth control.
Cytokinin (CK) has long been implicated as a promoter of bud outgrowth in plants, but exactly how this is achieved in coordination with other plant hormones is unclear. The recent discovery of strigolactones (SLs) as the long-sought branch-inhibiting hormone allowed us to test how CK and SL coordinately regulate bud outgrowth in pea (Pisum sativum). We found that SL-deficient plants are more se...
متن کاملInduction of cytokinin-independent tobacco tissues by substituted fluorenes.
Two morphactins and three aminofluorenes initiated the formation of compact tissue nodules in hormone-dependent tobacco callus cultures. These nodules, upon subculture, behaved like partially transformed plant tumors. They grew on cytokinin-free media, while control callus and nonnodule tissue still required an exogenous cytokinin source. The data indicate that substituted fluorenes, including ...
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 کاملOverview of Flower Bud Induction, Flowering and Fruit Set
Flowering is a critical step in fructification. No flowers mean no fruit, and when flower number is low crop load may be limited by the number of flowers formed. In most cases, however, citrus trees form a number of flowers exceedingly higher than the final number of fruits harvested, which usually is a very low percentage of the initial flower number. As in other species which form a large amo...
متن کاملInduction of proepicardial marker gene expression by the liver bud.
Cells of the coronary vessels arise from a unique extracardiac mesothelial cell population, the proepicardium, which develops posterior to the sinoatrial region of the looping-stage heart. Although contribution of the proepicardial cells to cardiac development has been studied extensively, it remains unresolved how the proepicardium is induced and specified in the mesoderm during embryogenesis....
