RNA polymerase (RNAP) loses activity during transcription as it stalls at various inactive states due to erratic translocation. Reactivation of these stalled RNAPs is essential for efficient RNA synthesis. Here we report a 4.7-Å resolution crystal structure of the Escherichia coli RNAP core enzyme in complex with ATPase RapA that is involved in reactivating stalled RNAPs. The structure reveals ...
Field trials of transgenic crops may result in unintentional transgene flow to compatible crop, native, and weedy species. Hybridization outside crop fields may create novel forms with potential negative outcomes for wild and weedy plant populations. We report here the outcome of large outdoor mesocosm studies with canola (Brassica napus), transgenic canola, a sexually compatible weed B. rapa, ...
Diversity of coral reef fish at Rapa Island (French Polynesia). The South Pacific island of Rapa (27°36'S, 144°21'W) is the southernmost inhabited island of French Polynesia. It is sufficiently isolated (the closest island lies 520 km northwest of Rapa) to be regarded as a separate geographic unit. In 2002, an international team of scientists conducted a marine biodiversity survey of Rapa (alga...
Numerous studies using single nucleotide polymorphisms (SNPs) have been conducted in humans, and other animals, and in major crops, including rice, soybean, and Chinese cabbage. However, the number of SNP studies in cabbage is limited. In this present study, we evaluated whether 7,645 SNPs previously identified as molecular markers linked to disease resistance in the Brassica rapa genome could ...
Based on RFLP analysis, two evolutionary lineages for Brassica diploid species have been proposed. These are (I) the nigra lineage and (II) the rapa/oleracea lineage. The phylogenetic relationship of Raphanus species to these two lineages is still unclear because chloroplast and mitochondrial DNA genomic restriction site variation suggests that Raphanus is more closely related to the rapa/...
GIGANTEA (GI) was originally identified by a late-flowering mutant in Arabidopsis, but subsequently has been shown to act in circadian period determination, light inhibition of hypocotyl elongation, and responses to multiple abiotic stresses, including tolerance to high salt and cold (freezing) temperature. Genetic mapping and analysis of families of heterogeneous inbred lines showed that natur...
Activation of the mammalian target of rapamycin (mTOR) signaling pathway is aberrant in autosomal-dominant polycystic kidney disease (ADPKD). The mTOR inhibitors, such as rapamycin, ameliorate PKD in rodent models, but clinical trials have not shown benefit, possibly as a result of low tissue concentrations of rapamycin at clinically tolerable doses. To overcome this limitation, we synthesized ...
Rapa Nui is one of the most remote islands in the world. As a young island, its biota is a consequence of both natural dispersals over the last ~1 million years and recent human introductions. It therefore provides an opportunity to study a unique community assemblage. Here, we extract DNA from museum-preserved and newly field-collected spiders from the genus Tetragnatha to explore their histor...
We aimed to investigate the effects of feeding fermented Brassica rapa L. on ecological and immunological changes in the mouse gut using in vitro cultivation tests and in vivo experiments in normal mice. In the preliminary in vitro study, two B. rapa L. products from different fermentation periods (one d [SF] or six months [LF]) were evaluated along with non-fermented vegetables (NF). Among the...
اهداف: شلغم از گیاهان دارویی پرمصرف است که بهنظر میرسد اثرات سودمندی بر هایپرلیپیدمی دارد. مطالعه حاضر بهمنظور بررسی اثرات کاهنده چربیهای خون عصاره آبی ریشه شلغم در موشهای صحرایی هایپرلیپیدمی انجام شد. مواد و روشها: در این مطالعه تجربی 40 سر موش صحرایی نر نژاد ویستار به پنج گروه مساوی کنترل سالم، هایپرلیپیدمی (دریافت روزانه نرمالسالین)، آتورواستاتین (دریافت روزانه 10میلیگرم بر کیلوگرم)...
