Abstract:
... Plant phospholipase D (PLD) and its product phosphatidic acid (PA) function in both abiotic and biotic stress signaling. However, to date, a PLD gene conferring the desired resistance to both biotic and abiotic stresses has not been found in cotton. Here, we isolated and identified a PLD gene GhPLDδ from cotton (Gossypium hirsutum), which functions in Verticillium wilt resistance and salt toleranc ...

Abstract:
... Application of crab shell chitin or pentamer chitin oligosaccharide to Arabidopsis seedlings increased tolerance to salinity in wild-type but not in knockout mutants of the LysM Receptor-Like Kinase1 (CERK1 / LysM RLK1) gene, known to play a critical role in signaling defense responses induced by exogenous chitin. Arabidopsis plants overexpressing the endochitinase chit36 and hexoaminidase excy1 g ...

Abstract:
... Despite its proven agronomic value, the plant disease suppressive effect of composts from olive waste has not been adequately investigated. In the present study, the disease suppressive potential of two olive waste (OW) composts against soil-borne plant pathogens was investigated. Both OW composts showed sizeable, active microbial populations, which were able to grow actively on chitin and cellulo ...

Abstract:
... The effect of cadmium on protein expression in the aerial parts of barley (Hordeum vulgare L. cv. ‘Mandolina’) seedlings was investigated by proteomic analysis of leaf apoplast proteins. Dramatic changes were observed in the protein pattern of intercellular washing fluid from Cd-treated (0–300 μM) barley leaves both by 1D- and 2D-PAGE. By mass spectrometric (MALDI-TOF and/or LC-MS/MS) analy ...

Among these, 13 CRB isolates were selected based on their ability to produce chitinase, colonize roots of tomato seedlings and reduce Fusarium wilt incidence. Four of these isolates produced statistically hig ...

Abstract:
... In nature, plants can recognize potential pathogens, thus activating intricate networks of defense signals and reactions. Inducible defense is often mediated by the detection of microbe or pathogen associated molecular pattern elicitors, such as flagellin and chitin. Chitosan, the deacetylated form of chitin, plays a role in inducing protection against pathogens in many plant species. We evaluated ...

Abstract:
... Chitin is a major component of fungal walls and insect exoskeletons. Plants produce chitinases upon pathogen attack and chito-oligomers induce defense responses in plants, though the exact mechanism behind this response is unknown. Using the ATH1 Affymetrix microarrays consisting of about 23,000 genes, we examined the response of Arabidopsis (Arabidopsis thaliana) seedlings to chito-octamers and h ...
