SCIENTISTS have overcome the resistance offered by three species of Indian pulses to conventional genetic engineering techniques, literally at the point of a gun.
S C Bhargava of the S K N College of Agriculture in Jobner in Rajasthan and A C Smigocki of the US Department of Agriculture report that they used a particle gun to fire two marker genes into moth bean, green gram and black gram (Current Science, Vol 66, No 6).

The bombarded embryos successfully developed into adult plants.
