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...
