This invention relates to dual roles of the pepper esterase protein as a biocontrol agent that can elicit defense reactions in plant cells and as direct fungal inhibitor that can block fungal penetration into plant cells. The possible enzymatic actions of the PepEST protein were elucidated in both fungus and plant to gain insight into the molecular mechanisms involved in the fungal resistance. Exogenously treated PepEST protein on the unripe pepper fruits decomposed the cuticles of the fruits and released glycerol and 9-octadecenamide. The treatment resulted in the massive generation of hydrogen peroxide in the unripe pepper fruit and simultaneously elicited the expression of defense-related genes in both absence and presence of the fungus.

Dual roles of pepper esterase as a biocontrol agent

The present invention related to two cDNA clones, designated to PepDef (pepper defensin protein gene) and PepThi (pepper thionin-like protein gene) and individual component; thereof including its coding region and its gene product; modification thereto; application of said gene, coding region and modification thereto; DNA construct, vectors and transformed plants each comprising the gene or part thereof.

Small and cysteine rich antifungal defensin and thionin-like protein genes highly expressed in the incompatible interaction

This invention relates to the use of enzymes for protection of plants against phytopathogenic fungi. In particular, the invention relates to the use of enzymes showing esterase activity for protecting plants against phytopathogenic fungi by inhibition of fungal appressorium formation. In addition, the invention relates to the use of recombinant pepper esterase expressed by using to protect plants against phytopathogenic fungi by inhibition of fungal appressorium formation.

Plant esterases for protecting plants and uses thereof

The present invention related to a cDNA clone, designated to PepCYP (pepper cytochrome P450 gene) and individual component; thereof including its coding region and its gene product; modification thereto; application of said gene, coding region and modification thereto; DNA construct, vectors and transformed plants each comprising the gene or part thereof.

Cytochrome P450 gene highly expressed in the incompatible interaction

Small and cysteine rich antifungal defensin and thionine-like protein genes highly expressed in the incompatible interaction

The present invention relates to a cDNA clone, designated to icc13 (incompatible,-,interactions) gene and individual component; thereof including its coding region and its gene product; modification thereto; application of the gene, coding region and modifications thereto; DNA construct, vectors and transformed plants each comprising the gene or part thereof.

Incompatible plant and pathogen interaction related gene

An improved method for producing flowering orchid plants by tissue culture is provided. The improvement comprises regenerating orchid plants from rhizome in a medium supplemented with cytokinin, i.e. BA 10 &mgr;M, or auxin, i.e. NAA 20 &mgr;M, or without plant growth regulators and culturing orchid plants without roots which are excised prior to transfer to subsequent medium containing high cytokinin content, i.e. 20-50 &mgr;M, low nitrogen content 3 mM, high phosphorus content, i.e. 6.25 mM, for about 1 to 3 months under the 16/8 hours light/dark photoperiod.

Method for producing flowering orchids in vitro

The present invention relates to a cDNA clone, designated to icc13 (incompatible Capsicum annuum-Colletotrichum gloeosporioides interactions) gene and individual component; thereof including its coding region and its gene product; modification thereto; application of said gene, coding region and modifications thereto; DNA construct, vectors and transformed plants each comprising the gene or part thereof.
