Expressed genes and their new alleles identification during fibre elongation reveal the genetic factors underlying improvements of fibre length in cotton
棉花 纤维伸长 表达基因簇
2024/4/16
本研究对亲本海7124、中棉所36及47个子代纤维发育5，10和15天的转录组数据分析，鉴定到35420个表达基因，构建了纤维伸长相关动态表达调控网络，其中10366个表达基因在子代中产生新等位基因（ENAs）；进一步鉴定到7个时空特异调控表达基因簇，差异表达分析筛选到105个候选基因，包含15个新等位基因。CRISPR-cas9系统敲除GhMAH1使纤维显著变短。本研究为解析陆海群体纤维长度变异...
Identification of candidate genes for key fibre-related QTLs and derivation of favourable alleles in Gossypium hirsutum recombinant inbred lines with G. barbadense introgressions
海岛棉 基因组组分 遗传作图群体
2024/5/17
该研究以渗入了海岛棉基因组组分的优质种质鲁原343为亲本，构建了包含239个重组自交系的遗传作图群体，利用SLAF标签构建了高密度遗传图谱，结合7个环境的表型数据，共鉴定104个纤维品质和产量性状QTLs，其中66个QTL共定位于19个QTL簇中。该研究团队通过进一步对鲁原343进行全基因组深度测序，解析鲁原343的遗传组成及其对纤维相关性状的遗传贡献，发现来自G. hirsutum races（...
Creating Novel Wx Alleles with Fine-tuned Amylose Levels and Improved Grain Quality in Rice by Promoter Editing using CRISPR/Cas9 System
CRISPR/Cas9 System Fine-tuned Amylose Grain Quality Rice
2023/8/9
In rice, the Waxy (Wx) gene encoding GBSSI (granule-bound starch synthase I) controls amylose synthesis in the endosperm and is the primary factor influencing grain eating and cooking quality (ECQ). T...
Identification of Multiple Alleles at the Wx Locus and Development of Single Segment Substitution Lines for the Alleles in Rice
rice waxy gene single segment substitution line allelic variation molecular marker-assisted sele
2009/1/7
The microsatellite markers 484/485 and 484/W2R were used to identify the multiple alleles at the Wx locus in rice germplasm. Fifteen alleles were identified in 278 accessions by using microsatellite c...
