puple rice photo    The mysterious ways of genes influencing the character of crop plants  through long periods of domestication, selection and modern breeding  continues to perplex genomics specialists, as found out by the genome  researchers working on coloured rice, Purpleputtu recently. Even the  whole Genome Sequencing (WGS) of the Purpleputtu rice variety has not  fully opened the windows to the genetic secrets to the researchers.  Researchers  at the SciGenom Research Foundation, Chennai, said the genome  sequencing of Purpleputtu revealed around 65,000 unique genetic  mutations compared with the reference sequence, of which about 50 are in  the genes of the colour pathway. The question of how specific genes and  gene networks control the expression of its uniqueness, the purple  colour, still remains an unanswered mystery, say researchers.  In  most cultivated white grain rice varieties, a regulatory gene, Rc is  missing 14 base pairs, which is believed to have changed the ...
