The essential oils of many plants have become popular in recent years and their bioactive principles have recently won several industry sectors, however their use as antibacterial and antifungal agents has been reported. This study focuses on the physico chemical and phytochemical with a study of the antimicrobial activity of essential oils of aromatic and medicinal plant of southwest Algeria, ...

Botrytis cinerea (B. cinerea) Pers. Fr. [teleomorph Botryo t in ia fucke l iana (de Bary ) Whetze l ] i s a phytopathogenic fungi responsible for grey mould, which is an important disease in more than 200 species of fruits, vegetables, ornamental crops and affecting a great number of organs[1]. Grey mould, cause important economic losses before and after the harvest[2], worldwide losses from th...

Damage-associated molecular pattern molecules (DAMPs) signal the presence of tissue damage to induce immune responses in plants and animals. Here, we report that High Mobility Group Box 3 (HMGB3) is a novel plant DAMP. Extracellular HMGB3, through receptor-like kinases BAK1 and BKK1, induced hallmark innate immune responses, including i) MAPK activation, ii) defense-related gene expression, iii...

Botrytis cinerea is an important pathogen that causes diseases in ornamental crops. In presentresearch several greenhouses of roses located in central region of Iran were surveyed toidentify the Botrytis cinerea. A total of 80 isolates were collected from rose greenhouses incentral region of Iran. Morphological identification was based on characters such asconidiophore and conidial length. Acco...

Uncinula necator and Botrytis cinerea are the most destructive pathogens of the grapevine in Tunisia and elsewhere. We used two strains of Bacillus subtilis group, B27 and B29 to control powdery mildew and the grey mold disease of the grapevine. Green house experiments showed that B29 and B27 strains of the bacteria efficiently reduced the severity of powdery mildew up to 50% and 60%, respectiv...

Rebecca Safran Q & A 5-methylcytosine. This specificity is unusual in fungi, but was predicted in prior studies of de novo methylation of repeated genes in C. cinerea. Recent attention has been focused on an additional modified base, 5-hydroxymethylcytosine, and its role in ‘poised chromatin’ in stem cells. The C. cinerea genome contains 38 copies of a gene predicted to carry out this conversio...

Cutinase of Botrytis cinerea has been suggested to play an important role in penetration of host tissues. A protein fraction with cutin hydrolyzing activity was purified from culture filtrates of B. cinerea induced for cutinase activity. An 18-kDa protein in this fraction was identified as cutinase and the corresponding gene cutA was cloned. The gene is present in a single copy in the genome of...

The Saccharomyces cerevisiae Elongator complex consisting of the six Elp1-Elp6 proteins has been proposed to participate in three distinct cellular processes: transcriptional elongation, polarized exocytosis and formation of modified wobble uridines in tRNA. In this study, we investigated the function of BcElp4 in Botrytis cinerea, which is homologous to S. cerevisiae Elp4. A bcelp4 deletion mu...
