本研究发现MYB5_A12在陆地棉(SG747)纤维起始及伸长早期的表达水平显著低于海岛棉(GZ75);通过QTL共定位分析发现,海岛棉GbMYB5_A12的等位基因型与纤维长度(FL)、纤维强度(FS)和衣分(LP)等性状显著正相关,其启动子区的顺式作用元件TFmatrixID_0063 (GATGTTGT)的自然变异可能导致海陆等位基因差异表达;通过酵母单杂及双荧光素酶报告基因实验验证了RAV...
SMAD3, a member of SMAD transcription factors, plays a key role in transforming growth factor-beta (TGF-β) signalling pathway and regulation of muscle growth. However, there was no strong evidence of ...
The identification of causative mutations affecting economically important traits has benefited the worldwide pig industry. We investigated the genetic variation at five loci including RYR1, IGF2, FUT...
Genetic variation of striped stem borer Chilo suppressalis populations in Guilan and Mazandaran provinces in Iran was studied in 2010 by means of RAPD markers. Collected 45 samples from 19 locations...
In this study, two donaors CN962 and 8065 were used to improve the resistance to northern leaf blight of the recurrent parent inbred line 08-641 (R08). A total of 79 lines (BC2F4) were developed by a ...
The protein diversity of 45 genotypes (forty genotypes selected within two gene pools and five varieties) of meadow fescue was examined. Genetic variation was described using ISTA/UPOV methods for cro...
Genetic variations are the raw materials of plant breeding and have been increasingly narrowed due to various reasons. Landraces are good sources of genetic variation, but need to be characterized fir...
An efficient antioxidant defense system represented by enzymatic and non-enzymatic forms is important in the control of oxidative stress caused by free radicals and other reactive species. Leaf antiox...
For improving the wood properties of Sakhalin fir (Abies sachalinensis) variation in annual ring structure and genetic variation in different environments were examined by X-ray densitometry. The spec...
Prolactin (PRL) and Growth hormone (GH) are secreted from the anterior pituitary gland and affect a wide variety of physiological functions in birds. A causal relationship between plasma PRL concentra...
One hundred and thirty one clones of Zoysia spp. collected from 59 sites on the coasts of Taiwan and its neighboring islets were analyzed using both random amplified polymorphicDNA (RAPD) and isozymes...
The seedling emergence of rice in direct seeding in submerged soil was investigated with respect to the degree of the forced sprouting, temperature and seedling depth. As a preliminary test, eight re...
The major histocompatibility complex (MHC) plays well-defined roles in eliciting immune responses and combating infectious diseases. The major histocompatibility complex of cattle is referred to as Bo...
In Australia, periodic waterlogging throughout the cotton growing season can cause production losses of up to 10%. There is limited information on the genetic variation in cotton for waterlogging tole...
We investigated longevity, ethylene production and ethylene sensitivity of flowers among 42 pot carnation cultivars. Our results indicate that there was a large genetic variability in flower longevity...
