Abstract Background Barley is known to be recalcitrant tissue culture, which hinders genetic transformation and its biotechnological application. To date, the ideal explant for remains limited immature embryos; mechanism underlying embryonic callus formation elusive. Results This study aimed uncover different transcription regulation pathways between calli formed from (IME) mature (ME) embryos ...
Coffea arabica L. is a species of coffee that contribute for more than seventy percent world production. Various attempts have been made to obtain large quantities planting material through propagation in vitro somatic embryogenesis technology. The objective this experiment was evaluate the effect different plant growth regulators (PGRs) on callus induction (indirect embryogenesis) AS2K clone A...
In situ embryo rescue for generation of wide intra‐ and interspecific hybrids of Panicum virgatum L.
Wide crosses have been used for decades as a method for transferring novel genetic material and traits in plant breeding. Historically, many products of wide crosses require tedious and inefficient surgical embryo rescue prior to embryo abortion to recover single plantlets. We have utilized transgenic switchgrass (Panicum virgatum L. cv Alamo) as a pollen donor in conjunction with antibiotic or...
BACKGROUND Efficient transformation and regeneration methods are a priority for successful application of genetic engineering to vegetative propagated plants such as grape. The current methods for the production of transgenic grape plants are based on Agrobacterium-mediated transformation followed by regeneration from embryogenic callus. However, grape embryogenic calli are laborious to establi...
