Interaction of nitric oxide and reactive oxygen species and associated regulation of root growth in wheat seedlings under zinc stress

The inhibition of root growth was investigated in wheat seedlings exposed to 3mM zinc (Zn). Zn treatment with or without 250µM 2-phenyl-4,4,5,5,-tetrame-thylimidazoline-3-oxide-1-oxyl (PTIO) or 10µM diphenylene iodonium (DPI) significantly inhibited growth, increased malondialdehyde content and lowe...
