study of callus induction and somatic embryogenesis in cotton
optimization of regeneration methods in cotton is necessary to improve and successful production of transgenic cotton cultivars by tissue culture technique. this study was conducted to determine the genotypic effect on callus induction in cotton using 3 genotypes (coker349, 4-s-4 and c1211) and coker 312 selected and a study was carried out in cotton research institute of gorgan using a factori...
متن کاملRecurrent Somatic Embryogenesis and Plantlet Regeneration in Psidium guajava L
A simple and efficient protocol for recurrent somatic embryogenesis and plant regeneration is one of the prerequisites for genetic improvement of guava. An efficient reproducible regeneration somatic embryogenesis protocol was developed in four genotypes of Psidium guajava L. using immature zygotic embryo as starter explant. Somatic embryogenesis induction was obtained on MS basal medium supple...
متن کاملUse of somatic embryogenesis as a vehicle for cotton transformation
Cotton has been aptly described as the prosperity plant owing to its unrivalled economic importance as a source of feedstock, food and oil, as well as raw material for diverse industrial applications, ranging from textile and footwear to automobiles, energy, medical and pharmaceutical. As such, over 180 million people of the world depend on its production for livelihood. However, cotton product...
متن کاملCell Suspension Culture, Somatic Embryo Genetic and Synthetic Seed Production in Different Cultivars of Potato
Extended Abstract Introduction and Objective: In order to overcome the contamination problems, as well as the usual method of increasing potato through micro tuber, micropropagation has been considered through tissue culture. The aim of this study was to evaluate the callus induction and embryogenesis in potato cultivars using leaf explants. Material and Methods: For this purpose, micropropa...
متن کاملCotton Embryogenesis
The formation of the zygote in cotton is accompanied by marked changes in the number and aggregation of the ribosomes. The zygote is formed approximately 14 hr after pollination but does not divide for some 56-60 hr. Electron microscope studies of the zygote during this period reveal a series of changes in the size and distribution of polysomes which may provide information on this important st...
