Genetic variation in MYB5_A12 is associated with fibre initiation and elongation in tetraploid cotton
MYB5_A12 陆地棉 纤维起始 纤维伸长 表达水平 海岛棉
2024/5/17
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...

Natural variation of OsGluA2 is involved in grain protein content regulation in rice
Natural variation OsGluA2 grain protein rice
2023/8/9
Grain protein content (GPC) affects rice nutrition quality. Here, we identify two stable quantitative trait loci (QTLs), qGPC-1 and qGPC-10, controlling GPC in a mapping population derived from indica...

The most significant breakthrough in plant biotechnology is the development of the techniques to transform genes from unrelated sources into commercially important crop plants to develop resistance ag...
Variation of Morphological and Agronomic Traits in Hybrids of Trifolium pratense × T. medium and a Comparison with the Parental Specie
interspecific hybrids morphological traits persistence ed clover rhizomes zigzag clover
2014/2/25
Trifolium pratense L. is a high-yielding and high-quality fodder crop. However, it shows low persistence,
which may be overcome by hybridisation with species that produce rhizomes. Hybrids between T...
Determining the levels of genetic variation using SSR markers in three Turkish barley materials known as Tokak
Barley genetic variation landrace microsatellite markers
2010/2/24
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...
Genotypic and Environmental Variation of Lag Period of Pod Growth in Soybean
Lag period Photoperiod Pod growth Soybean
2009/7/29
Pod growth in soybean (Glycine max (L.) Merr.) begins several days after flower opening, compared with more immediate growth in other beans. We investigated the relationship between genotype, raceme ...
Genotypic Variation in Response of Rainfed Lowland Rice to Prolonged Drought and Rewatering
Drought Drought recovery Osmotic adjustment Rainfed lowland rice Root
2009/7/29
Duration of the drought period is important for plant response during drought and after rewatering. We hypothesized that, if drought duration is extended, (1) high seedling vigor and rapid developmen...
Relative Contribution of Hetero- and Auto-trophic Growth to Genotypic Variation of Seedling Vigor in Rice (Oryza sativa L.)
Autotrophic growth Genotypic variation Heterotrophic growth Oryza sativa L.,Relative growth rate Seed reserve Seedling vigor
2009/7/24
To elucidate the major physiological process to cause genotypic variation in the seedling vigor of rice, we analyzed the dry matter accumulation in the seedling for diverse cultivars distinguishing he...
