为了探究Al-Sr10具有低光泽属性的本质,对该材料进行X射线衍射、X射线能量色散谱、面扫元素分析、8~14μm红外发射率、光泽度及400~760 nm可见光反射率测试。并采用高能球磨法制备该颜填料,通过扫描电子显微镜等手段探究Al-Sr10颜填料的组分、形态和光学性能随球磨时间的变化。结果表明,Al-Sr10表面易氧化形成灰黑色氧化锶,以及固溶体中的锶元素产生等离激元效应共同作用导致材料消光;Al-Sr10颜填料的物相不会随球磨时间变化,在一定时间内,材料的片状化程度、发射率和光泽度性能随时间的延长得到改善,其中球磨15 h后的颜填料其片状化程度高,发射率低至0.123,光泽度低至3.8。

Stripe rust,caused by Puccinia striiformis ***(Pst),is a devastating disease in wheat *** and characterizing new resistance genes/QTL is crucial for wheat breeding *** this study,we fine-mapped and characterized a stripe rust resistance gene,YRAYH,on chromosome arm 5BL in the Chinese wheat landrace Anyuehong(AYH).Evaluations of stripe rust response to prevalent Chinese Pst races in near-isogenic lines derived from a cross of Anyuehong and Taichung 29 showed that YrAYH conferred a high level of resistance at all growth *** mapping using a large segregating population of 9748 plants,narrowed the YRAYH locus to a 3.7 Mb interval on chromosome arm 5BL that included 61 annotated *** analysis of two NIL pairs identified 64 upregulated differentially expressed genes(DEGs)in the resistant NILs(NILs-R).Annotations indicated that many of these genes have roles in plant disease resistance *** a combined approach of fine-mapping and transcriptome sequencing,we identified a serine/threonine-protein kinase SRPK as a candidate gene underlying YrAYH.A unique 25 bp insertion was identified in the NILs-R compared to the NILs-S and previously published wheat *** InDel marker was developed and co-segregated with *** trait evaluation of the NILs suggested that YrAYH not only reduces the impact of stripe rust but was also associated with a gene that increases plant height and spike length.
