Nitric oxide signalling in plant interactions with pathogenic fungi and oomycetes.

abstract：:Tobacco plants were transformed by leaf disc regeneration with the VvHT1 (Vitis vinifera hexose transporter 1) cDNA under the control of the constitutive CaMV 35S promoter in a sense or antisense orientation. Among the 20 sense plants and 10 antisense plants obtained, two sense plants showed a mutant phenotype when gr...
