Shoot branching patterns result from the spatio-temporal regulation of axillary bud outgrowth. Numerous endogenous, developmental and environmental factors are integrated at the bud and plant levels to determine numbers of growing shoots. Multiple pathways that converge to common integrators are most probably involved. We propose several pathways involving not only the classical hormones auxin,...

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...

Juniperus drupacea Labill. (Cupressaceae) is a species with ecological and medicinal value. In Europe, it native only in southern Greece, listed as endangered. Due to its uniqueness, this study attempted, for the first time, an vitro propagation effort of Syrian juniper. Explants lateral shoot tips were surface-sterilized cultured on Murashige Skoog (MS) medium. The cultures subcultured MS, woo...

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....

present study was conducted to consider the effects of different concentrations of 2,4-d and ba on somatic embryogenesis induction, development and maturation of three strawberry cultivars (kurdistan, parose and camarosa). for this purpose, leaf blade, nodal, petiole, stamen and flower bud calli were cultured on murashige and skoog (ms) medium supplemented with 2, 4 dichlorophenoxyacetic acid (...

Abstract Crop genetic diversity has a significant role in improving new plants through breeding. The chrysanthemum contains the most mutant varieties, making mutation breeding one of widely utilized procedures for ornamental plants. goal this research is to use gamma irradiation induce variation and improve features. In vitro bud explants white ‘Bacardi’ type were treated with rays at 20 Gy on ...
