RNAi-mediated oncogene silencing confers resistance to crown gall tumorigenesis.
Crown gall disease, caused by the soil bacterium Agrobacterium tumefaciens, results in significant economic losses in perennial crops worldwide. A. tumefaciens is one of the few organisms with a well characterized horizontal gene transfer system, possessing a suite of oncogenes that, when integrated into the plant genome, orchestrate de novo auxin and cytokinin biosynthesis to generate tumors. ...
متن کاملWhole-Genome Characterization of Prunus necrotic ringspot virus Infecting Sweet Cherry in China
Prunus necrotic ringspot virus (PNRSV) causes yield loss in most cultivated stone fruits, including sweet cherry. Using a small RNA deep-sequencing approach combined with end-genome sequence cloning, we identified the complete genomes of all three PNRSV strands from PNRSV-infected sweet cherry trees and compared them with those of two previously reported isolates.
متن کاملSurvey of Cherry necrotic rusty mottle virus and Cherry green ring mottle virus incidence in Korea by Duplex RT-PCR
The incidence of Cherry necrotic rusty mottle virus (CNRMV) and Cherry green ring mottle virus (CGRMV) have recently been occurred in Korea, posing a problem for sweet cherry cultivation. Since infected trees have symptomless leaves or ring-like spots on the pericarp, it is difficult to identify a viral infection. In this study, the incidence of CNRMV and CGRMV in sweet cherry in Gyeongbuk prov...
متن کاملRNAi-mediated DNA silencing
Tucker, and Edwin Chapman (University of Wisconsin, Madison, WI) find that PIP 2 is a plasma membrane dock for synaptotagmin-1 (syt), a transmembrane protein localized in secretory vesicle membranes, when calcium is absent. This dock may ensure speedy and directed fusion in response to calcium influx. The syt dock has two calcium-binding domains in its cytoplasmic region, called C 2 A and C 2 B...
متن کاملشناسایی و بررسی تنوع ژنتیکی ویروس لکه‌حلقوی بافت مرده هسته‌دارها (Prunus necrotic ring spot virus) در درختان میوه هسته‌دار و دانه‌دار استان کردستان
شمار 149 نمونۀ برگی از درختان میوۀ هسته‌دار و دانه‌دار استان کردستان هنگام بهار و تابستان سال‌های 1394 و 1396 به‌منظور شناسایی مولکولی و بررسی گوناگونی ژنتیکی عامل لکه حلقوی بافت مردۀ درختان هسته‌دار جمع‌آوری شدند و با آغازگرهای اختصاصی ژن پروتئین پوششی PNRSV-F3/PNRSV-R3 آزمون RT-PCR شدند. نتیجهها RT-PCR نشان دادند که 8/20 درصد از نمونه‌ها آلوده به PNRSV بودند. سیزده جدایه بر پایۀ نوع میزبان و...
