Elucidating the dynamic of drought tolerance rice, MR219-4 to the Xanthomonas oryzae infection

Rice (Oryza sativa) is a primary source of food for more than half of the world’s population. Despite its importance, rice production struggles with various pathogenic attacks particularly by Xanthomonas oryzae that causes bacterial blight. Overcoming this issues is of utmost priority especially w...
