endopolygalacturonase/necrosis

CLPG1, an endopolygalacturonase (endoPG) gene of Colletotrichum lindemuthianum, was transferred to tobacco (Nicotiana tabacum) leaves by using the Agrobacterium tumefaciens transient delivery system. The following four constructs were prepared: CLPG1, with or without its signal peptide (SP; PG1,

Six endopolygalacturonases from Botrytis cinerea (BcPG1 to BcPG6) as well as mutated forms of BcPG1 and BcPG2 were expressed transiently in leaves of Nicotiana benthamiana using agroinfiltration. Expression of BcPG1, BcPG2, BcPG4, BcPG5, and mutant BcPG1-D203A caused symptoms, whereas BcPG3, BcPG6,

Plants perceive microbial invaders using pattern recognition receptors that recognize microbe-associated molecular patterns. In this study, we identified RESPONSIVENESS TO BOTRYTIS POLYGALACTURONASES1 (RBPG1), an Arabidopsis (Arabidopsis thaliana) leucine-rich repeat receptor-like protein, AtRLP42,

Phytophthora parasitica is an oomycete plant pathogen that causes severe disease in a wide variety of plant species. In our previous study, we discovered a multigene family encoding endopolygalacturonases (endoPG) in Phytophthora parasitica. Here, we screened the genomic library of Phytophthora

Alternaria brown spot, caused by Alternaria alternata (Fr.) Keissler, causes leaf, twig, and fruit lesions and reduces yield and fruit quality of many tangerines (Citrus reticulata Blanco) and their hybrids (3). In 2003, characteristic symptoms of brown spot were observed on young leaves and fruit

Botrytis cinerea is a necrotrophic pathogen that attacks more than 200 plant species. Here, the nonpathogenic mutant A336, obtained via insertional mutagenesis, was characterized. Mutant A336 was nonpathogenic on leaves and fruits, on intact and wounded tissue, while still able to penetrate the host
