Rapamycin was found to increase (11% to 16%) the lifespan of male and female C57BL/6J mice most likely by reducing the increase in the hazard for mortality (i.e., the rate of aging) term in the Gompertz mortality analysis. To identify the pathways that could be responsible for rapamycin's longevity effect, we analyzed the transcriptome of liver from 25-month-old male and female mice fed rapamyc...
Flowering time is an important agronomic trait, and wide variation exists among Brassica rapa. In Arabidopsis, FLOWERING LOCUS C (FLC) plays an important role in modulating flowering time and the response to vernalization. Brassica rapa contains several paralogues of FLC at syntenic regions. BrFLC2 maps under a major flowering time and vernalization response quantitative trait locus (QTL) at th...
Glucosinolates and their breakdown products have been recognized for their effects on plant defense, human health, flavor and taste of cruciferous vegetables. Despite this importance, little is known about the regulation of the biosynthesis and degradation in Brassica rapa. Here, the identification of quantitative trait loci (QTL) for glucosinolate accumulation in B. rapa leaves in two novel se...
The glucosinolate biosynthetic gene AOP2 encodes an enzyme that plays a crucial role in catalysing the conversion of beneficial glucosinolates into anti-nutritional ones. In Brassica rapa, three copies of BrAOP2 have been identified, but their function in establishing the glucosinolate content of B. rapa is poorly understood. Here, we used phylogenetic and gene structure analyses to show that B...
Strong evidence exists for polyploidy having occurred during the evolution of the tribe Brassiceae. We show evidence for the dynamic and ongoing diploidization process by comparative analysis of the sequences of four paralogous Brassica rapa BAC clones and the homologous 124-kb segment of Arabidopsis thaliana chromosome 5. We estimated the times since divergence of the paralogous and homologous...
Studies into the cell death program termed apoptosis have resulted in new information regarding how cells control and execute their own demise, including insights into the mechanism by which death-preventing factors can inhibit Bax-induced caspase activation. We investigated high temperature stress-induced cell death in Brassica rapa. Using a yeast functional screening from a Brassica rapa cDNA...
ویروس پیچیدگی برگ شلغم (Turnip curly top virus, TCTV) یک جمینی ویروس جدید است که اخیراً از مزارع شلغم استان فارس گزارش شده است. از آنجا که این ویروس از نظر سازمان‌دهی ژنوم از سایر جمینی ویروس‌ها متفاوت است، هنوز بسیاری از ویژگی‌های بیولوژیکی آن از جمله ناقل و سایر میزبان‌های طبیعی آن مورد مطالعه قرار نگرفته است. به منظور شناسایی ناقل TCTV در شرایط آزمایشگاهی، توانایی زنجرک‌های Circulifer hae...
Stable expression of a transgene may lead to increased fitness for wild plants after acquiring the transgene via crop-weed hybridization. Here, we investigate the stability of Bt toxin content in wild Brassica rapa acquiring the Bt gene from Bt Brassica napus. The Bt toxin content in nine Bt-expressing B. napus lines was 0.80-1.70 micro g/g leaf tissue throughout the growing season. These nine ...
We have developed experiments and materials to model human genetics using rapid cycling Brassica rapa, also known as Fast Plants. Because of their self-incompatibility for pollination and the genetic diversity within strains, B. rapa can serve as a relevant model for human genetics in teaching laboratory experiments. The experiment presented here is a paternity exclusion project in which a chil...
اهداف: درد احساس پیچیدهای است که روح و روان را متاثر میسازد و در بسیاری موارد نیاز به استفاده از داروهای مختلف برای کاهش درد وجود دارد. این پژوهش با هدف بررسی اثر عصاره الکلی ریشه شلغم بر کاهش درد حاد و مزمن ناشی از تزریق فرمالین در موش‌های صحرایی نر بالغ انجام شد. روش‌ها: در این مطالعه تجربی از 40 سر موش صحرایی نر بالغ استفاده شد که به 5 گروه 8تایی کنترل، شاهد ، آزمایش 1، آزمایش 2 و آزمایش 3...
