A novel mycovirus with the proposed name “Magnaporthe oryzae botourmiavirus 9” (MoBV9) was found in rice blast fungus Magnaporthe isolate SH05. The virus has a positive single-stranded RNA genome of 2,812 nucleotides and contains single open reading frame predicted to encode an RNA-dependent polymerase that is closely related those some unclassified viruses family Botourmiaviridae, including Pl...

This paper presents a divide-and-conquer approach that aims at making QSIM simulation tractable. We consider dynamical systems the structure of which can be represented by compartments. The system model is decomposed into sub-models tightly connected through shared variables on the basis of the analysis of the causality relations intrinsically captured by the compartmental model structure. The ...

To investigate the in-situ response to a stress, grapevine leaves have been subjected to mass spectrometry imaging (MSI) experiments. The Matrix Assisted Laser Desorption/Ionisation (MALDI) approach using different matrices has been evaluated. Among all the tested matrices, the 2,5-dihydroxybenzoic acid (DHB) was found to be the most efficient matrix allowing a broader range of detected stilben...

Most WRKY transcription factors activate expression of defence genes in a salicylic acid- and/or jasmonic acid-dependent signalling pathway. We previously identified a WRKY gene, VvWRKY1, which is able to enhance tolerance to fungal pathogens when it is overexpressed in tobacco. The present work analyzes the effects of VvWRKY1 overexpression in grapevine. Microarray analysis showed that genes e...

Impact of disease severity on infected bunches upon a yield grape variety Vanec, caused by Plasmopara viticola (Berk. & M.A. Curtis) Berl. De Toni., every year causes damage to the vines infection while they are still unripe. It is essential assess Downy Mildew in vineyards predict loss accurately. The software platform 'image J' was used detect and quantify measuring berries relative healt...

Stilbene synthase is a key enzyme for the production of the phytoalexin resveratrol. Some clones of Vitis sylvestris, a wild European grapevine species which is almost extinct, have been shown to accumulate more resveratrol in response to different forms of stress. In the current study, we asked whether the induction of stilbene synthase transcripts in Hoe29, one of the V. sylvestris clones wit...
