Which part of the tobacco plant is infected by Meloidogyne incognito? [2016] (a) Flower (b) Leaf (c) Stem (d) Root
Option D Meloidogyne incognita infects the roots of tobacco plants. The RNAi technique is utilized to establish resistance to infection in these plants. RNA interference (RNAi) is a phenomenon induced by double-stranded RNA (dsRNA) in which gene expression is inhibited through specific degradation of mRNA. The process involves converting dsRNA into short RNAs that point ribonucleases toward target homologous mRNA. With the aid of an enzyme known as Dicer, long double-stranded RNA is cut up into manageable pieces. Small interfering RNA, or siRNA, is the name given to these tiny bits.
