Transcriptome analysis of barley anthers: effect of mannitol treatment in microspore embryogenesis
Carbohydrate starvation is an efficient stress treatment for induction of microspore embryogenesis. Transcriptome analysis of anthers response to mannitol treatment using the 22k Barley1 GeneChip revealed large changes in gene expression. Statistical analysis and filtering for 4-fold or greater changes resulted in 2,673 genes, of which 887 were up-regulated and 1,786 down-regulated. Great diffe...
متن کاملExpression profiles in barley microspore embryogenesis
In barley, microarray technology has allowed to study the gene expression profiling associated with the stress pretreatment phase of microspore embryogenesis, where the reprogramming of microspores takes place. Transcriptome analysis of anthers before and after four days of mannitol pretreatment, revealed changes in the expression of 2,673 genes. A thorough study of these differentially express...
متن کاملSomatic Embryogenesis and Plant Regeneration from Embryonic Axes and Cotyledons Explants of Tea (Camellia sinenesis L.)
In the present study, 2, 4-dichlorophenoxyacetic acid (2, 4-D) was assessed individually for its effectiveness to induce somatic embryogenesis in tea (Camellia sinenesis L.). Embryonic axes and cotyledons explants were dissected from the seeds. Explants were cultured on Murashige and Skoog (MS) medium containing 0, 1 and 5 mM 2, 4-D alone for embryonic axes and 0, 1 and 5 mM 2, 4-D along with 0...
متن کاملPhytochemical Evaluation and Plant Regeneration Through Somatic Embryogenesis of Ferulago angulata subsp. Carduchorum (Boiss. and Hausskn), an Endangered Medicinal Plant
Background: Ferulago angulata is an important medicinal plant and endemic to Iran which is an endangered Plant. Objective: The aim of this study was to achieve an efficient method for propagation of this plant and evaluation of essential oil content and composition in habitat. Metthods: Essential oils were extracted by hydrodistillation using Clevenger-type apparatus and its composition was ...
متن کاملبررسی اثر ژنوتیپ، پیش‌تیمارتنشی و محیط‌کشت در باززایی میکروسپورهای جو از طریق کشت بساک
Doubled haploid production is one of the best breeding methods to produce homozygous (pure) lines. Microspore culture technique is the most efficient method for production of doubled haploid plants. This research was carried out to study the effect of genotypes, stress pre-treatments and culture media on the callus induction and plant regeneration from microspores of anthers in barley (Hordeum ...
