摘要
摘要:微芒豆(Combretum micranthum G. Don)原产于西非,是一种野生灌木、藤本植物或乔木,因其具有多种健康和营养价值而受到重视。尽管如此,缺乏与其经济价值相称的遗传信息。本研究旨在测定西非塞内加尔东部的小红花(C. microranthum)种质的核DNA含量和染色体数目。首次确定了基因组大小的估计值,并利用活跃生长的根尖分析了染色体数目。基因组大小的平均值、中位数、最小值和最大值分别为1587.44 Mb、1540.85 Mb、1472.24 Mb和2146.66 Mb。细胞学分析显示染色体数目为2 n = 2x = 26。该研究结果可用于结构和功能基因组学、基因组测序、系统发育研究以及育种和驯化计划。
Nuclear DNA content and chromosome number determination in a Sahel medicinal plant, Combretum micranthum G. Don
ABSTRACT Combretum micranthum G. Don, also known as kinkéliba, is native to West Africa where the plant grows wild as a shrub, liana, or tree and is valued for its numerous attributes including health and nutritional benefits. Despite this, genetic information commensurate with its economic value is lacking. The aim of this study was to determine the nuclear DNA content and chromosome numbers of C. micranthum germplasm from eastern Senegal, West Africa. Genome size estimates were determined, for the first time, and chromosome number was analyzed using actively growing root tips. The mean, median, minimum, and maximum genome size estimates were 1587.44 Mb, 1540.85 Mb, 1472.24 Mb, and 2146.66 Mb, respectively. Cytological analysis revealed a chromosome number of 2 n = 2x = 26. The results of this investigation can be useful for structural and functional genomics, genome sequencing endeavors, and phylogenic studies as well as breeding and domestication programs.
期刊介绍:
Journal of Crop Science and Biotechnology (JCSB) is a peer-reviewed international journal published four times a year. JCSB publishes novel and advanced original research articles on topics related to the production science of field crops and resource plants, including cropping systems, sustainable agriculture, environmental change, post-harvest management, biodiversity, crop improvement, and recent advances in physiology and molecular biology. Also covered are related subjects in a wide range of sciences such as the ecological and physiological aspects of crop production and genetic, breeding, and biotechnological approaches for crop improvement.
