Verticillium wilt of olive (VWO), caused by dahliae, is a major concern in many olive-growing countries. An efficient VWO control measure the use tolerant/resistant cultivars. Low information available about secondary metabolites and its relationship with tolerance. In this study, comprehensive metabolic profiling roots six cultivars differing their level tolerance/susceptibility to was address...

Lysin-motif (LysM) receptor kinases (LYKs) play essential roles in recognition of chitin and activation of defense responses against pathogenic fungi in the model plants Arabidopsis and rice. The function of LYKs in non-model plants, however, remains elusive. In the present work, we found that the transcription of two LYK-encoding genes from cotton, Gh-LYK1 and Gh-LYK2, was induced after Vertic...

Verticillium dahliae is a fungal pathogen that causes wilt disease in a wide range of host plants. Characterization of virulence, morphological, and molecular variations among V. dahliae isolates from different geographic origins is essential for any breeding program aimed at producing plant cultivars resistant to this disease. We characterized virulence variation among V. dahliae isolates...

Participation of phospholipase A (PLase A) in plant signal transduction has been documented for auxin stimulation of growth but not for elicitation of any plant defense response. In this paper, we report two independent assays for monitoring PLase A induction in plant cells and have used these assays to evaluate whether transduction of defense-related signals might require PLase A activation. O...

The reaction of pepper breeding lines under organic production conditions to Verticillium wilt, viruses and phytoplasma was observed at Maritsa Vegetable Crop Research Institute, Plovdiv, Bulgaria during two successive years. diseases severity recorded, when symptoms dahliae, Phytoplasma were deeply expressed. dahliae attack index for early varied widely from 15.04% line O58/14 43.83% O26/16. F...

Pectin, the major non-cellulosic component of primary cell wall can be degraded by polygalacturonases (PGs) and pectin methylesterases (PMEs) during pathogen attack on plants. We characterized two novel enzymes, VdPG2 VdPME1, from fungal plant Verticillium dahliae. VdPME1 was most active citrus methylesterified (55–70%) at pH 6 a temperature 40 °C, while polygalacturonic acid 5 50 °C. Using LC-...
