      Immature cotyledons of open-pollinated fruits from three sour cherry cultivars (Prunus cerasus L.) were excised and cultured on Murashige and Skoog medium supplemented with various combinations of auxin and cytokinin to induce somatic c embryogenesis occurred principally when using the combinations of 2,4-dichlorophenoxyacetic acid plus kinetin. In the studies of other woody plants, the frequency of somatic embryogenesis varied from % to 63% [27,28,29,34], and the frequency of SE in K. paniculate was at a high level in the research. Similarly, NAA has been reported to influence somatic embryo development .

      Several studies have shown that the cells and somatic embryos contain enormous amounts of differentially expressed genes during somatic embryogenesis in cotton (Yang et al., , ). Plant hormones such as auxin obviously affect the somatic embryogenesis process, but how gene expression is regulated at the epigenetic level is still not clear. A number of recent reports on somatic embryogenesis in woody plants such as Norway spruce (Picea abies), Loblolly pine (Pinus taeda), Sandalwood (Santalurn album), Citrus, Mango (Mangifera indica), etc., offer a ray of hope of: a) inexpensive clonal propa gation for large-scale production of plants or "emblings" or "somatic embryo plants", b 5/5(1).

    In grapevine, anther culture is often used to obtain somatic embryos. We identified the best developmental stage to initiate immature anther culture, in relation to the microsporogenesis and the outward appearance of anthers and flowers. Three grape genotypes were observed for common features. Six individual stages were identified, from when the pollen mother cells were in premeiotic . Fernandez C.

Studies on somatic embryogenesis in some cultivars of table grape (Vitis vinifera L.) by Zuher Mustafa Bensaad Download PDF EPUB FB2

Somatic embryogenesis is frequently used method for improvement of plant characteristics and creation of genetic diversity.

Plant regeneration in grapes via somatic embryogenesis has been established in sp. Vitis rupestris L., Vitis aestivalis L., subgenus Muscadinia Planchon. Somatic embryos in seeded and seedless table and vine cultivars of.

The goal of this study was to establish somatic embryogenesis as an efficient method for virus elimination from valuable Croatian cultivars and creating a reliable source of healthy plants.

Somatic embryogenesis is the preferred method for cell-to-plant regeneration of grapevine. In this study, we tested the embryogenic capacity of anther-derived calli from 59 grape genotypes, representing a diverse group of Vitis vinifera and hybrid varieties, and hybrids and accessions of non-vinifera Vitis species.

Most genotypes were tested on two types of media: MST1 Cited by:   Somatic embryogenesis is the preferred method for cell to plant regeneration in Vitis vinifera L.

However, low frequencies of plant embryo conversion are commonly found. In a previous work we obtained from cut-seeds of a grapevine infected with the Grapevine leafroll associated viruses 1 and 3 (GLRaV-1 and GLRaV-3), high rates of direct regeneration, embryo plant conversion and by: 7.

So far, regeneration of the Muscadine grape was achieved by somatic embryogenesis from leaves (ROBACKER, ) and zygotic embryos (GRAY, ) but not by organogenesis. Table 1 Embryogenesis percentage from anthers In some cultivars the efficiencies obtained nevertheless various authors have reported successful somatic embryogenesis of grape for a.

Somatic embryogenesis (SE) is a widely used method in grape (Vitis vinifera) biotechnology as it permits the rapid multiplication of clonal material from a single explant source. from clonal mature tissue. Preliminary studies have obtained somatic embryos and plants from leaf tissue of one muscadine grape culti-var, although embryogenesis incidence was low (Robacker and Lane, ).

This report describes a method for high-frequency somatic embryo induction from leaf tissue in two muscadine grape cultivars. Somatic Embryogenesis from Anther, Whole Flower, and Leaf Explants of Some Grapevine Cultivars Article in Plant Tissue Culture and Biotechnology 26(2) December with Reads.

During induction of SE, differences were observed among cultivars in the efficiency of embryogenesis. Percentage of embryogenic explants of the different cultivars calculated across the media and explant types, ranged between and % with about fold difference between genic capacity of ‘Albanello’ (%) and ‘Nerello cappuccio’ (%) was greater than.

Embryogenesis was induced in cut-seeds cultured on EIM2 (Table 4) in explants from all four cultivars each infected with two viruses (Table 5). Mean rates of regeneration indicated that Valencí Blanc was the lowest responding variety of those assayed in this experiment.

TDZ induces high-frequency somatic embryogenesis in some plant species when used alone or in combination with other growth regulators (reviewed by Anwar et al., ).

In addition, somatic embryogenesis can be induced by various stresses, specific hormone treatments, and over-expression of specific genes (Rose and Nolan, ). A great number of varieties have been described in grapevine; however, few of them are currently in use.

The increasing concern on varietal diversity loss has encouraged actions for recovering and preserving grapevine germplasm, which represents valuable resources for breeding as well as for diversification in grapevine-derived products. On the other hand, it is expected that this important.

This study was carried out to establish a reliable and practical protocol of plant regeneration through organogenesis and somatic embryogenesis of immature male flowers of four cultivars of Musa spp.

cvs. Berangan, Rastali, Mas and Raja as well as micromorphological studies and optimization of plant transformation protocol via microprojectile bombardment of immature male flowers of Musa spp. Abstract. Grape (Vitaceae, Vitis spp.) is a deciduous temperate fruit crop of ancient contains two subgenera, Euvitis Planch., the bunch grape species that all contain 38 somatic chromosomes, and Muscadinia Planch., the muscadine grapes with 40 somatic chromosomes (Einset and Pratt, ; Winkler et al., ).Species in each subgenus are interfertile but are only partially.

Somatic embryogenesis, with a success rate of to %, was achieved in seedless bunch grape cultivars ‘Autumn Roy-al Seedless’, ‘Crimson Seedless’, and with muscadine grape cultivars ‘Alachua’, ‘Summit’, and ‘Tara’ when the callus was subcultured on those NN media with or without plant growth regulators (PGR).

An efficient protocol of somatic embryogenesis (SE) has been developed for the first time in four half-high blueberry (Vaccinium corymbosum L. × V. angustifolium Ait.) cultivars. Maximum somatic embryogenesis potency was noticed in ‘Khalasah’ followed by ‘Muzati’ cultivar. Comparative account of somatic embryogenesis induction percentage in six date palm cultivars is shown in Fig.

Anthers and ovaries of six grapevine cultivars (three Vitis vinifera L., two V × Labruscana L. H. Bailey, and one complex hybrid) were extracted from flower buds over 2 yr and cultured on three media reported to promote somatic embryogenesis in Vitis tissues. The highest percent embryogenesis from the hybrid ‘Chancellor’ and V.

vinifera ‘Chardonnay’, ‘Merlot’, and ‘Pinot Noir.conventional methods [2] and therefore regeneration of whole plants by somatic embryogenesis and organogenesis has been intensively studied [3,8].

According to some authors, combinations of different cytokinins such as, thidiazuron and kinetin were more effective for establishing morphogenetic cultures in some ra cultivars whereas BA. Anthurium andraeanum Lind.

is the second most important tropical flower in the world flower market. Somatic embryogenesis and plant regeneration in Anthurium has been reported previously; however, a stable and effective method for its commercial use has not been available.
