Plant Biotechnol J 133—42 A two gene—two promoter system for enhanced expression of a restorer gene barstar and development of improved fertility restorer lines for hybrid seed production in crop plants. UBQ10 was taken as an internal control. Restoring full pollen fertility in transgenic male-sterile tobacco Nicotiana tabacum L. This simplicity, in combination with its reversible folding transition, means that barnase has been extensively studied in order to understand how proteins fold.

Although it is not directly involved in acid-base bzrstar, Lys27 is also critical for activity; it has been implicated in transition-state substrate binding.

The cytoplasmic and nuclear male sterility is limited by maintenance of multiple lines, partial and unstable male sterility and limited fertility restoring gene sources, all of which restrict the economic benefits of the hybrid 6. Production of transgenic male sterile tobacco plants with the cDNA encoding a ribosome inactivating protein in Dianthus sinensis L. A novel hybrid seed system for plants.


Restoration of pollen fertility in F1 progeny is a prerequisite for hybrid seed production. There have been no protests against such videshi GM oil by so-called swadeshi and green groups, who have directed all their protests against GM mustard, despite it being a product of indigenous, publicly-funded research. Functional distinctions between yeast TATA elements.
