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...
Seed protein electrophoresis for assessment of genetic variation within genotypes of meadow fescue (Festuca pratensis Huds)
acid-PAGE genetic diversity meadow fescue SDS-PAGE
2014/3/10
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...

Safflower Carthamus tinctoriuos antioxidant carotenoids chlorophyll
2010/9/14
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...
Genetic Variation of Zoysia as Revealed by Random Amplified Polymorphic DNA (RAPD) and Isozyme Pattern
Genetic variation Geographic distribution Isozyme RAPD Zoysia
2009/7/23
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...
Studies on Evaluating Method and Genetic Variation of Seedling Emergence in Direct Seeding under Submerged Soil Condition
Gene stock Evaluating method Seedling emergence Rice Direct seeding Submerged soil condition
2009/7/9
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...
Genetic Variation for Waterlogging Tolerance in Cotton
Genetic Variation Waterlogging Tolerance Cotton
2009/4/30
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...

Genetic variation Bougainvillea glabra cultivars RAPD markers isozymes patterns
2010/11/12
This study was aimed at determining the genetic relationships among the most important
Bougainvillea cultivars grown at most of the gardens in Egypt using random amplified Polymorphic DNA (RAPD) tech...
The variation between wild barley lines ( Hordeum murinum, Hordeum bulbosumand Hordeum vulgare spontaneum) orig-inated from Turkey were investigated comparatively at the molecular level with the Rando...
Genetic Variation among Cotton（Gossypium hirsutum L.）Cultivars for Seed-Set Efficiency
Cotton seed set genotype
2009/1/9
Seed-set efficiency (SSE) is one of the most important within-boll yield components in cotton production. Increased SSE can lead to increased seed number and, ultimately, to greater fiber yield. A fie...
