A cDNA, BohLOL1, encoding a protein containing three zf-LSD1 (zinc finger-Lesions Simulating Disease resistance 1) domains was cloned from growing bamboo (Bambusa oldhamii) shoots. A phylogenetic analysis revealed that BohLOL1 is a homolog of Arabidopsis LSD1 and LOL1 (LSD-one-like 1), which have been reported to act antagonistically in controlling cell death via the maintenance of reactive oxygen...
Aldehyde dehydrogenases (ALDHs) catalyze the irreversible oxidation of a broad spectrum of reactive aldehydes to their corresponding carboxylic acids. Although the proteins have been studied from various organisms and at different growth stages in plants, their potential roles in pathogen infection have not been examined. Here we isolated and functionally characterized a pathogen-inducible ALDH gene...
WRKY transcription factors are crucial regulatory components of plant responses to pathogen infection. In the present study, we report isolation and functional characterization of the pathogen-responsive rice WRKY30 gene, whose transcripts accumulate rapidly in response to salicylic acid (SA) and jasmonic acid (JA) treatment. Overexpression of WRKY30 in rice enhanced resistance to rice sheath blight...
Sporisorium reilianum f. sp. zeae is an important biotrophic pathogen that causes head smut disease in maize. Head smut is not obvious until the tassels and ears emerge. S. reilianum has a very long life cycle that spans almost the entire developmental program of maize after the pathogen successfully invades the root. The aim of this study was to understand at a molecular level how this pathogen...
Pepper (Capsicum annuum L.) provides a good experimental system for studying the molecular and functional genomics underlying the ability of plants to defend themselves against microbial pathogens. Cell death is a genetically programmed response that requires specific host cellular factors. Hypersensitive response (HR) is defined as rapid cell death in response to a pathogen attack. Pepper plants...
Main conclusionA novel broad-spectrum powdery mildew resistance genePmPB74was identified in wheat-Agropyron cristatumintrogressionline Pubing 74. Development of wheat cultivars with broad-spectrum, durable resistance to powdery mildew has been restricted by lack of superior...
Main conclusionThe DUF642 geneVqDUF642, isolated from the Chinese grape speciesV. quinquangularisaccession Danfeng-2, participates in berry development and defense responses againstErysiphe necatorandBotrytis cinerea.The proteins with domains of unknown function 642 (DUF642) comprise a large protein family according to cell wall proteomic analyses in plants. However, the works about functional characterization...
