Resistance to Tomato spotted wilt virus isolated from paprika (TSWV-Pap) was overcome at high temperatures (30 ± 2°C) in both accessions of Capsicum annuum S3669 (Hana Seed Company) and C. chinense PI15225 (AVRDC Vegetable Genetic Resources). S3669 and PI15225, which carrying the Tsw gene, were mechanically inoculated with TSWV-Pap, and then maintained in growth chambers at temperatures ranging...

Induced systemic resistance in chickpea against wilt disease caused by Fusarium oxysorum f. sp. ciceri (FOC) was studied by treating the seeds with benzo (1,2,3)-thiadizole-7-carbothioic acid smethyl ester (Bion), salicylic acid (SA) and dipotassium hydrogen phosphate (K2HPO4). Reduction in disease was observed in both type of applications but seed dressing was found more effective than soaking...

Bacteria and fungi that colonise plant surfaces and internal plant tissues (epiphytes and endophytes respectively) are ubiquitous, residing latently or actively colonising the plant locally as well as systemically. Endophytic microorganisms generally originate from the epiphytic communities of the root or aerial surfaces as well as from within seed material. Besides entering plants through natu...

In Arabidopsis thaliana, significant efforts to determine the effect of naturally occurring variation between phenotypically divergent accessions on different biotic or abiotic stresses are underway. Although it is usually assumed that induced systemic resistance (ISR) against pathogen will covary with plant genetic variation, this assumption has not been tested rigorously in previous experimen...

Salicylic acid (SA) is a defense hormone required for both local and systemic acquired resistance (SAR) in plants. Pathogen infections induce SA synthesis through up-regulating the expression of Isochorismate Synthase 1 (ICS1), which encodes a key enzyme in SA production. Here we report that both SAR Deficient 1 (SARD1) and CBP60g are key regulators for ICS1 induction and SA synthesis. Whereas ...

BACKGROUND Recently, the IMPRES study revealed that systemic imatinib improves exercise capacity in patients with advanced pulmonary arterial hypertension. Imatinib blocks the tyrosine kinase activity of the platelet-derived growth factor (PDGF)-receptor (PDGFR), acts antiproliferative and relaxes pulmonary arteries. However so far, the relaxant effects of imatinib on pulmonary veins (PVs) and ...

Bacterial canker of tomato is a systemic disease caused by Clavibacter michiganensis (Cm), which poses grave threat to production worldwide. Towards the identification genes underlying resistance Cm infection, transcriptome resistant inbred backcross line IBL2353 carrying Rcm2.0 locus derived from Solanum habrochaites LA407 and susceptible lycopersicum Ohio88119 was comparatively analyzed after...
