番茄疮痂病菌T3小种抗性的QTL分析

 利用由抗番茄细菌性疮痂病菌T3小种材料PI114490构建的回交自交群体分析其抗性遗传规律,鉴定与抗性连锁的分子标记。从516个SSR、SNP和InDel标记中筛选到72个在亲本之间有多态性的标记。单标记分析结果显示,PI114490对T3小种的抗性由分布于1、3、8和11号染色体上的多个QTL控制,其中11号染色体上的QTL能提供高达56.5%的抗性;分析各回交自交系的基因型发现,这些QTL之间可能存在互作。这为进一步研究PI114490对T3小种的抗性机理和抗病育种提供了参考依据。     

Oceanographic features that define the habitat of Pacific ocean perch, Sebastes alutus

This study investigates the possibility that oceanographic features could have effects on the variations observed in the apparent abundance of a demersal rockfish, Pacific ocean perch, Sebastes alutus. Simultaneous monitoring of physical variables and indices of fish abundance was achieved by attaching oceanographic equipment to the fishing gear of commercial vessels and sampling the fish catch. It was found that perch prefer a temperature range from at least 4.8C to 6.7C and that their movement patterns are linked to the movement of these temperatures by coastal wind patterns. Perch prefer areas with steep bathymetry, characterized by turbulent activity due to interactions between the local bathymetry and tidal currents.     

Coefficients for the dry-weight rank method of botanical analysis of pasture

The coefficients of the dry-weight-rank (DWR) method ('t Mannetje & Haydock, 1963) can be predicted from the general occurrence of the geometric series relationship between abundance and rank of species in a pasture using either an estimate of the percentage contribution of the first ranked species, or from the ratio of the contribution of two species.

Rapid diagnosis of herpes simplex virus infections with fluorescent antibody

A fluorescent microscopy technique is described which may prove useful in differentiating clinically similar lesions into lesions of herpes simplex virus etiology and nonherpetic lesions. Herpes simplex virus was isolated from the specimens which yielded positive fluorescence, and no virus was isolated from the specimens which yielded no fluorescence.
