Molecular Cloning of HbPR-1 Gene from Rubber Tree, Expression of HbPR-1 Gene in Nicotiana benthamiana and Its Inhibition of Phytophthora palmivora
This is the first report to present a full-length cDNA (designated HbPR-1) encoding a putative basic HbPR-1 protein from rubber tree (Hevea brasiliensis) treated with salicylic acid. It was characterized and also expressed in Nicotiana benthamiana using Agrobacterium-mediated transient gene expression system in order to investigate the role of HbPR-1 gene in rubber tree against its oomycete pat...
متن کاملNegative Chemotaxis of Zoospores of the Fungus Phytophthora palmivora
347 Phytophthora palmivora zoospores are repelled by many low molecular weight cations. This negative chemotactic response occurs at a different threshold concentration for each cation, that for the most effective ion, H+, being 150 ,!AM. The effectiveness of different cations parallels their ionic conductivities, the most active cations having the highest conductivities. It is suggested that t...
متن کاملThe plant defense and pathogen counterdefense mediated by Hevea brasiliensis serine protease HbSPA and Phytophthora palmivora extracellular protease inhibitor PpEPI10
Rubber tree (Hevea brasiliensis Muell. Arg) is an important economic crop in Thailand. Leaf fall and black stripe diseases caused by the aggressive oomycete pathogen Phytophthora palmivora, cause deleterious damage on rubber tree growth leading to decrease of latex production. To gain insights into the molecular function of H. brasiliensis subtilisin-like serine proteases, the HbSPA, HbSPB, and...
متن کاملSalicylic Acid Protects Photosynthesis against Cadmium Toxicity in Pea Plants
In the present study we have investigated the possible mediatory role of salicylic acid (SA) in protecting photosynthesis against cadmium (Cd) toxicity. The exposure of pea plants to increasing Cd concentrations (0.5, 1.0, 2.0 and 5.0 µM) during early stages of their establishment caused a gradual decrease in shoot and root fresh weight accumulation, the rate of CO 2 fixation and the activity o...
متن کاملA central role of salicylic Acid in plant disease resistance.
Transgenic tobacco and Arabidopsis thaliana expressing the bacterial enzyme salicylate hydroxylase cannot accumulate salicylic acid (SA). This defect not only makes the plants unable to induce systemic acquired resistance, but also leads to increased susceptibility to viral, fungal, and bacterial pathogens. The enhanced susceptibility extends even to host-pathogen combinations that would normal...
