Nicotiana benthamiana Matrix Metalloprotease 1 (NMMP1) gene confers disease resistance to Phytophthora infestans in tobacco and potato plants.

We previously isolated Nicotiana benthamiana matrix metalloprotease 1 (NMMP1) from tobacco leaves. The NMMP1 gene encodes a highly conserved, Zn-containing catalytic protease domain that functions as a factor in the plant's defense against bacterial pathogens. Expression of NMMP1 was strongly induced during interactions between tobacco and one of its pathogens, Phytophthora infestans.

The DOF transcription factor Dof5.1 influences leaf axial patterning by promoting Revoluta transcription in Arabidopsis.

Dof proteins are transcription factors that have a conserved single zinc finger DNA-binding domain. In this study, we isolated an activation tagging mutant Dof5.1-D exhibiting an upward-curling leaf phenotype due to enhanced expression of the REV gene that is required for establishing adaxial-abaxial polarity.

Characterization of full-length enriched expressed sequence tags of dehydration-treated white fibrous roots of sweetpotato.

Sweetpotato (Ipomoea batatas (L). Lam.) is relatively tolerant to unfavorable growth conditions such as drought, yet has not been exploited to provide a better understanding of the molecular basis of drought stress tolerance.
