Hybridization, a common process in nature, can give rise to a vast reservoir of allelic variants. Combination of these allelic variants may result in novel patterns of gene action and is thought to contribute to heterosis. In this study, we analyzed genome-wide allele-specific gene expression (ASGE) in the super-hybrid rice variety Xieyou9308 using RNA sequencing technology (RNA-Seq). We identi...
هدف: در این مطالعه به بررسی ارتباط ki-67 با stage سرطان سینه در بیمارستان بوعلی طی سالهای 90-1389 پرداختیم. روش مطالعه: در این مطالعه توصیفی – تحلیلی مقطعی، 144 نفر از مراجعین به بیمارستان بوعلی از سال 89 تا 90 مورد بررسی قرار گرفتند که به صورت در دسترس انتخاب و وارد مطالعه شدند. یافته ها: ki-67 در 9/81 درصد از بیماران مثبت بود. stageتومور در 4/26 درصد یک، در 2/47 درصد دو و در 4/26 درصد سه بو...
Chloroplast development and chlorophyll (Chl) biosynthesis in plants are regulated by many genes, but the underlying molecular mechanisms remain largely elusive. We isolated a rice mutant named yss2 (young seedling stripe2) with a striated seedling phenotype beginning from leaf 2 of delayed plant growth. The mutant developed normal green leaves from leaf 5, but reduced tillering and chlorotic l...
cml in breif cml is characterized by the proliferation of large numbers of immature wbc in the blood and bone marrow. in most of the patients , it is a clonal disorder in which all cell lines, express the philadelphia chromosome)q/22 translocation(it accounts for 20 of all leukemias and most cases occur over 25 yrs of age. the disease usually begins insidiously,but symptoms referable to anemia ...
The paper presents the results of research on biological and economic efficiency new herbicide Femida, OD (2,4 D-acid, 320 g/l 2-ethylhexyl ester + 4.2 chlorsulfuron) produced by Schelkovo Agrohim, Ltd., Russia. It’s established that with protection winter wheat at tillering stage in spring reduction infestation annual perennial weeds amounts to more than 85 %, particular, blind weed,

The qTSN4 was identified as rice QTL (Quantitative Traits Locus) increasing total spikelet number per panicle and flag leaf area but potentially reducing panicle number depending on the environment. So far, this trade-off was mainly observed at grain maturity and not specifically studied in details, limiting the apprehension of the agronomic interest of qTSN4. This study aimed to understand the...
Metre-resolution airborne multispectral images have been used to estimate crop biomass in rice (Orysa sativa L.). Images were acquired at four stages of crop development; mid-tillering, flowering, panicle initiation and immediately prior to harvest. The imaging system, flown in a light aircraft, comprised four CCD video cameras; recording in the infrared, red, green and blue wavebands. Normaliz...
Fertilizers usually enhance potassium (K) content and other naturally occurring radioactive materials in agricultural fields that eventually enter the human food chain through plants. In this study, pot-grown rice plants planted in soil that is relatively high in natural radioactive content was used to estimate the individual influence of fertilizer applications on the uptake of 226Ra, 232Th, a...
