“…Dm-AMP1 protein folds into a small and compact b-barrel, which is stabilized by four internal disulfide bridges were treated with anti-DmAMP1 and FITC-conjugated goat anti-rabbit IgG. Bar corresponds to 10 lm (Yun et al 1997). Secretory proteins have to pass through endoplasmic reticulum for correct folding and assembly of proteins (Vitale and Denecke 1999).…”

Magnaporthe oryzae and Rhizoctonia solani, are among the most important pathogens of rice, severely limiting its productivity. Dm-AMP1, an antifungal plant defensin from Dahlia merckii, was expressed in rice (Oryza sativa L. sp. indica cv. Pusa basmati 1) using Agrobacterium tumefaciens-mediated transformation. Expression levels of Dm-AMP1 ranged from 0.43% to 0.57% of total soluble protein in transgenic plants. It was observed that constitutive expression of Dm-AMP1 suppresses the growth of M. oryzae and R. solani by 84% and 72%, respectively. Transgenic expression of Dm-AMP1 was not accompanied by an induction of pathogenesis-related (PR) gene expression, indicating that the expression of DmAMP1 directly inhibits the pathogen. The results of in vitro, in planta and microscopic analyses suggest that Dm-AMP1 expression has the potential to provide broad-spectrum disease resistance in rice.

“…These findings indicate that the genes might be responsive to other pathogen infections. Yun et al (1997) found that TLPs are not only effective against a broad range of fungal species, including several plant pathogens, but that they also exhibit specificity toward certain fungi.…”

“…PR5 proteins from mutant barley grain inhibited growth of Trichoderma viride and Candida albicans (Hejgaard et al, 1991). In addition to inhibiting hyphal growth and spore germination, some TLPs greatly increase the permeability of fungal and oomycete plasma membranes (Yun et al, 1997;Kitajima and Sato, 1999). Overexpression of TLPs appears to enhance resistance to fungal disease (Liu et al, 1994;Zhu et al, 1996;Chen et al, 1999).…”

“…Resistance in the host is often manifested by a hypersensitive response, which results in localized cell death at the site of infection, structural alterations, and production of a wide range of plant defense molecules such as antimicrobial proteins (Broekaert et al, 1997;Yun et al, 1997;Grant and Mansfield, 1999). It has been suggested that the H 2 O 2 produced by the OxO members of germin and GLP family may act as a messenger for the initiation of other defense-related genes in the same cell or in neighboring cells and activate an effective defensive response.…”
