A high-quality reference genome is critical for understanding genome structure, genetic variation and evolution of an organism. Here we report the de novo assembly of an indica rice genome Shuhui498 (R498) through the integration of single-molecule sequencing and mapping data, genetic map and fosmid sequence tags. The 390.3 Mb assembly is estimated to cover more than 99% of the R498 genome and ...
It is known that the common cultivated rice (Oryza sativa) was domesticated from Asian wild rice, O. rufipogon. Among the morphological differences between them, loss of seed shattering is one of the striking characters specific for the cultivated forms. In order to understand the genetic control on shattering habit, QTL analysis was carried out using BC(2)F(1) backcross population between O. s...
A central element of the Green Revolution was the widespread adoption of semidwarf rice cultivars (SRCs) that more than doubled worldwide rice production (1). The high-yield potentials of modern SRCs are attributed primarily to their improved harvest index, lodging resistance, and responsiveness to high inputs (primarily nitrogen and water) (1–3), contributing to their adoption in irrigated are...
Transgenic rice plants overexpressing a mutant rice gene for anthranilate synthase alpha subunit (OASA1D) accumulate large amounts of free tryptophan (Trp) with few adverse effects on the phenotype, except for poor germination and weak seedling growth. Metabolic profiling of 8-d-old seedlings of Nipponbare and two high-Trp lines, HW1 and HW5, by high performance liquid chromatography-photo diod...
Cadmium (Cd) in rice is a major source of Cd intake for people on a staple rice diet. The mechanisms underlying Cd accumulation in rice plant are still poorly understood. Here, we characterized the physiology and genetics of Cd transport in a high-Cd-accumulating cultivar (Jarjan) of rice (Oryza sativa). Jarjan showed 5- to 34-fold higher Cd accumulation in the shoots and grains than the cultiv...
امروزه گردآورندگان اطلاعات به ویژه سازمان های آماری با دو مسئله متضاد مواجه اند. از یکسو، بنا به وظیفه قانونی و رشد روزافزون تقاضا برای اطلاعات جمعآوری شده، خود را متعهد به انتشار هر چه گسترده تر و باکیفیت تر اطلاعات به شکل داده های آماری می بینند و از سوی دیگر با توجه به نگرانی عمومی نسبت به افشا اطلاعات شخصی و وظیفه قانونی این سازمانها برای مراقبت از اطلاعات خصوصی پاسخگویان، باید این تضمین را...
Abstract Background Seed-set density is an important agronomic trait in rice. However, its genetic mechanism complex. Chromosome segment substitution lines (CSSLs) are ideal materials for studying complex traits. Results A rice CSSL, Z749, with a dense and erect panicle phenotype, was identified among progeny of the recipient parent Nipponbare donor Xihui 18. Z749 carried seven segments (averag...
phosphate (p) is one of the key substrates in energy metabolism and biosynthesis of nucleic acids and membranes. in order to identify molecular mechanisms involved in rice adaptation to p deficiency, we applied a proteomic approach to compare a rice parental line, nipponbare (sensitive), and its near isogenic line (nil6-4) (resistant). the experiment was conducted using a completely randomized ...
