芝麻核心种质株高构成相关性状的遗传变异及关联定位

以我国216份芝麻核心种质为材料,分析芝麻株高及其构成相关性状的变异、相互关系等,利用79对EST-SSR、AFLP和SRAP引物对供试材料基因组进行检测并进行标记-性状关联分析,检测群体中与株高构成性状相关的DNA变异位点.结果表明,株高及其构成性状的变异均呈现连续变化,变异丰富,变异系数均在10％以上;相关性分析和多元回归拟合株高及其构成因素间的关系表明,主茎始蒴高度、主茎果轴长度是影响株高差异的主要因素.利用GLM(Q)和MLM(Q+K)模型共检测到34个变异位点同时与供试群体两年的株高构成显著关联,对表型变异解释率在1.89％～5.29％,平均为2.82％,其中与主茎始蒴高度显著关联的标记位点M20E12-3被2种模型均检测到.此外,研究发现株高构成因素受基因型、环境和两者互作影响,且均达到极显著水平.     

Genetic Diversity in Crop Improvement

SUMMARY

The use of genetic diversity to form modern crops is one of the most remarkable accomplishments of agriculture. Even in the age of genomics, genetic diversity remains the cornerstone of crop improvement. There is extensive diversity in soybean and its ancestors. Much of this diversity has been collected though opportunities to extend collections remain. Genetic diversity has been used extensively in Asian breeding but utilization of exotic germplasm has been limited in North America. Capturing the value of diversity is easy for some traits but quite difficult for other traits, such as yield. New procedures and technology may greatly facilitate understanding and effective use of these exotic yield alleles. For the foreseeable future though, progress in capturing yield value from exotic germplasm through traditional breeding will continue to outstrip our scientific understanding of the alleles themselves. Public institutions will need to facilitate access to germplasm to increase utilization of diversity so it favorably impacts humanity.

Conserving rare plants in locally-protected urban forest fragments: A case study from Miami-Dade County,Florida

We consider Miami-Dade County’s Environmentally Endangered Lands (EEL) network of preserves as a means to conserve rare plant species in urban and suburban forest fragments. In this rapidly urbanizing landscape, upland forests are at particularly high risk of development. We examined the number of rare plant species present in preserves based on the site area, ecosystem type and management practices using the EEL database maintained by the county and a database of plant species inventories collected by the Institute for Regional Conservation. About 99% of the area of the EEL system is located in southern Miami-Dade. Pine rockland forests are primarily in the outer suburbs of the county where fire can be used most effectively for management. Hardwood hammock forests are distributed throughout the county including within the urban core. All 56 EEL forested sites under study contained at least one rare plant species. Small sites often contained high numbers of rare species per unit area, but presumably at lower population sizes. The type of upland forest was not related to the mean richness of rare or state-listed plant species. Public access was not related to the mean richness of rare plants, but was negatively associated with the richness of state-listed plant species.
