Abstract

Improving fiber quality has been an important breeding goal for cotton breeders. Better understanding of fiber development helps cotton scientists to devise a strategy for crop improvement either through marker-assisted selection or via manipulation of fiber genes. USDA-ARS Southern Regional Research Center (SRRC) in New Orleans, LA has a long history of studying postharvest fiber chemistry and physics, but research on cotton fiber development in planta began only in 1985. During the period of 1985 to 2008, cotton fiber bioscience research at SRRC was led by Barbara Triplett whose research focused on dissecting cotton fiber development at the level of gene processes and testing hypotheses about the functional roles of specific genes or cohorts of coordinately regulated genes in important fiber traits. Following stakeholders’ recommendations, the cotton fiber bioscience research unit (CFBRU) was established in 2007 at SRRC. Currently, research projects at the CFBRU are focusing on 1) in-depth research to understand the basic biology of cotton fiber development, 2) genetically mapping fiber quality and yield quantitative trait loci, and 3) using the obtained information in breeding to improve cotton fiber quality. Major recent accomplishments include, but are not limited to, identification of causative genes for Ligon-lintless 1 and immature fiber mutations and identification of stable large-effect fiber quantitative trait loci and their application in practical breeding.
美国农业部-农业研究局南部区域研究中心棉纤维生物科学研究的历史
提高棉花纤维品质一直是棉花育种者的重要育种目标。对纤维发育的更好理解有助于棉花科学家设计出一种通过标记辅助选择或通过操纵纤维基因来改良作物的策略。位于新奥尔良的美国农业部农业研究中心(USDA-ARS)南部区域研究中心(SRRC)在棉花收获后的纤维化学和物理方面有着悠久的研究历史,但对棉花纤维在植物中的发育的研究直到1985年才开始。1985年至2008年期间,Barbara Triplett博士领导了SRRC棉纤维生物科学研究,她的研究重点是在基因过程水平上剖析棉纤维的发育,并验证特定基因或协调调节基因群在重要纤维性状中的功能作用假设。根据利益相关者的建议,棉纤维生物科学研究单位(CFBRU)于2007年在SRRC成立。目前,CFBRU的研究项目主要集中在:1)深入研究棉纤维发育的基础生物学;2)定位棉纤维品质和产量数量性状位点;3)利用获得的信息在育种中提高棉纤维品质。近年来取得的主要成果包括,但不限于,Ligon-lintless 1和未成熟纤维突变的致病基因的鉴定,稳定的大效纤维数量性状位点的鉴定及其在实际育种中的应用。
