The basal transcription factor IIE (TFIIE) is thought to be one of the last factors to be assembled into a preinitiation complex (PIC) at eukaryotic promoters after RNA polymerase II and TFIIF have been incorporated. It was shown that a primary function of TFIIE is to recruit and cooperate with TFIIH in promoter melting. Here, we show that the large subunit of TFIIE (E56) can directly stimulate...
Virus-induced gene silencing (VIGS) is a valuable tool for identification and characterization of genes function. To improve the efficiency of VIGS in different organ, we developed an organ-specific VIGS that could be applied to tomato (Solanum lycopersicum cv Micro Tom) leaves, flowers and fruits respectively. With phytoene desaturase (PDS) as a reporter gene, almost up to 100% of efficiency o...
New antibiotics with novel mechanisms of action are urgently needed to overcome the growing bacterial resistance problem faced by clinicians today. PC190723 and related compounds represent a promising new class of antibacterial compounds that target the essential bacterial cell division protein FtsZ. While this family of compounds exhibits potent antistaphylococcal activity, they have poor acti...
منظور شناسایی قارچ های عامل پوسیدگی ریشه باقلا در استان لرستان، در سال های 1386 و 1387 بیش از 43 بار از نمونه های مشکوک به پوسیدگی ریشه و طوقه باقلا، نمونه برداری شد و در مجموع 121 جدایه قارچ از ریشه و طوقه گیاهان آلوده جدا شد.در این بررسی مشخص شد که فراوانی قارچ fusarium solani که موجب پوسیدگی ریشه باقلا می شود، از سایر جدایه ها بیشتر و خسارت ناشی از آن در مزارع استان زیاد است و بعد از آن بیشت...
