1不同氮源对海洋微藻氮同位素分馏作用的影响显示文摘以海链藻 (Thalassiosirapseudonana)为研究对象 ,分别考察了以硝酸盐、铵盐和尿素为氮源的氮同位素分馏作用。在建立相应理论模型基础上 ,分别计算出各个实验体系的ε值。结果表明 ,在藻类生长初期 ,δ1 5N均较低 ,其δ1 5N的积累主要发生在指数增长期 ,在稳定期达到最高 ,与氮源的初始δ1 5N相同 ;不同氮源的氮同位素分馏作用也不相同 ,其中以铵盐最强 ,硝酸盐次之 ,尿素最弱。考虑到实际情况下氮化合物并非单一存在 ,作者还进一步考察了上述3种氮源混合后对其同位素分馏作用的影响 ,发现混合氮源体系的表观ε值介于单一氮源时的最大与最小ε值之间 ,该结果较好地解释了Montoya等 ( 1 991 )在Chesapeak湾的现场实验结果。俞志明 Waser N A D Harrison P J 2004海洋与湖沼2004,35,6:13
2Mapping QTL associated with Verticillium dahliae resistance in the cultivated strawberry(Fragaria×ananassa)显示文摘A biparental cross of octoploid strawberry segregating for resistance to Verticillium dahliae,the causative agent of Verticillium wilt,was screened under field conditions for three seasons.Average wilt scores were significantly associated with multiple QTL,which were mostly significant across all years.Markers significantly associated with the traits were used to screen material with known wilt resistance and susceptibility phenotypes.A clear and statistically significant relationship was observed between resistant,tolerant and susceptible material and the total number of markers present in the different resistance classes.In field situations resistance QTL appear to behave in an additive manner.These markers are abundant in the cultivated strawberry germplasm indicating that,despite the large number of markers,clear genetic gain is possible through marker-assisted breeding.L Antanaviciute NŠurbanovski N Harrison K J McLeary D W Simpson F Wilson D J Sargent R J Harrison 2015Horticulture Research2015,2,1:5
