Hrip 1 is a kind of hypersensitive response inducing protein from Alternaria
tenuissima used in tobacco to activate its defense response and systemic
resistance. Researchers from Chinese Academy of Agricultural Science studied
the role of the protein Hrip 1 in the abiotic and biotic stress in
transgenic Arabidopsis thaliana.

Results show an improved plant growth in terms of plant height, dry weight,
silique length, germination rate and root length under salt and drought
conditions in Arabidopsis with Hrip1 expression. A higher resistance to
pathogen attack in transgenic Arabidopsis with Hrip1 expression was also
observed upon the infection of Botrytis. These findings show that the
protein Hrip1, can be a possible gene to be used in breeding new resistant
crops.
