Abstract

Efficiency of plant transformation is less than optimal for many important species, especially for monocots which are traditionally recalcitrant to transformation, such as wheat. And due to limited number of selectable marker genes, identification or selection of those cells that have integrated DNA into appropriate plant genome and to regenerate fully developed plants from the transformed cells, becomes even more difficult. Some of the widely used marker genes belong to the categories of herbicide or antibiotic resistance genes and flourescent protein genes. As they become an integral part of plant genome along with promoters prokaryotic or eukaryotic origin, there are certain health and environmental concerns about the use of these reporter genes. These marker genes are also inefficient with respect to time and space. In this study we have found a novel visible selection agent AtMYB12, to screen transgenic wheat, with in days after transformation. Transformed coleoptiles as well as cells regenerating from transformed cultured scutella, phenotypically exhibit purple pigmentation, making selection possible in limited and reasonable cost, time and space.
