Somatic embryogenesis is widely preferred as the regeneration route for in vitro studies in cotton. However, the regeneration efficiency through this approach is low; a problem that is believed to be as a result of the biochemical properties of the plant. The objective of this study was to investigate possible relationships between three biochemical factors (reducing sugars, phenols, and free a...
Somatic embryogenesis (SE) in forest trees is considered as one powerful approach in cloning elite genotypes. However, SE is difficult to achieve in tissue or cell beyond the mature embryo phase in trees and its physiological process involved are also poorly understood. Recently metabolic profiling studies have been contributed to understand the mechanism involved in SE process of plant [1-3]. ...
Somatic embryogenesis is an in vitro system employed for plant propagation and the study of embryo development. Nitrogen is essential for plant growth and development and, hence, the production of healthy embryos during somatic embryogenesis. Glutamine has been shown to increase plant biomass in many in vitro applications, including somatic embryogenesis. However, several aspects of nitrogen nu...
an efficient method for producing doubled haploid plants of date palm ( phoenix dactylifera l.) was established using in vitro colchicine treatment of anthers. to this study male inflorescences were harvested in the appropriate developmental stage. separated anthers after one day cold (4°c) pretreatment, in uninucleate stage of microspore were transferred to the modified y 3 medium containing d...
Advances in horticulture plant biotechnologies provide new opportunities for researchers to study the field of vegetative propagation and genetic engineering. Developments of clonal propagation methods, especially somatic embryogenesis (SE), have numerous potential applications. This paper reviewed progress of research on SE in horticultural plants in last decade; analyzed plant regeneration ha...
A new protocol was established for the regeneration of Solanum nigrum by frog egg-like bodies (FELBs), which are novel somatic embryogenesis (SE) structures induced from the root, stem, and leaf explants. The root, stem, and leaf explants (93.33%, 85.10%, and 100.00%, respectively) were induced to form special embryonic calli on Murashige and Skoog (MS) medium containing 1.0 mg/L 2,4-dichloroph...
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 (...
