Enhancing the tolerance of Saccharomyces cerevisiae to inhibitors derived from lignocellulose is conducive to producing biofuel and chemicals using abundant lignocellulosic materials. Vanillin is a major type of phenolic inhibitor in lignocellulose hydrolysates for S. cerevisiae. In the present work, the factors beneficial to vanillin resistance in yeast were identified from the vanillin-resist...
BACKGROUND The understanding of the molecular basis of yeast tolerance to ethanol may guide the design of rational strategies to increase process performance in industrial alcoholic fermentations. A set of 21 genes encoding multidrug transporters from the ATP-Binding Cassette (ABC) Superfamily and Major Facilitator Superfamily (MFS) in S. cerevisiae were scrutinized for a role in ethanol stress...
The resistance mechanisms to azole antifungal agents were investigated in this study with two pairs of Candida glabrata clinical isolates recovered from two separate AIDS patients. The two pairs each contained a fluconazole-susceptible isolate and a fluconazole-resistant isolate, the latter with cross-resistance to itraconazole and ketoconazole. Since the accumulation of fluconazole and of anot...
BACKGROUND Pretreatment of biomass for lignocellulosic ethanol production generates compounds that can inhibit microbial metabolism. The furan aldehydes hydroxymethylfurfural (HMF) and furfural have received increasing attention recently. In the present study, the effects of HMF and furfural on redox metabolism, energy metabolism and gene expression were investigated in anaerobic chemostats whe...
مطالعات نشان داده سالیسیلیک اسید به عنوان یک عامل کلیدی در القای مقاومت گیاهان به تنش های محیطی به خصوص بیماری ها نقش دارد. پس از هجوم پاتوژن ها به خصوص عوامل قارچی، گیاهان با القای مقاومت اکتسابی سیستمیک که با افزایش میزان سالیسیلیک اسید درونی گیاه همراه است مسیرهای پیام رسانی گسترده ای از قبیل رونویسی از ژن های رمز کننده پروتئین های وابسته به بیماری زایی (pathogenesis related proteins)، آنزیم...
Directional transport of the phytohormone auxin is required for the establishment and maintenance of plant polar growth. Natural auxins, primarily indole 3-acetic acid (IAA), are ampipathic weak acids that diffuse into membrane bilayers when protonated, suggesting that polar auxin movement is primarily established at the point of cellular efflux. However, recent evidence indicates that proton-c...
