A complete study was made of 20 Spanish herbaria and of the literature concerning the regional flora of Spain in order to define the geographical limits of the different genera of the subtribe Hordeineae found in Spain. Accordingly, several expeditions were undertaken to the greater part of the Spanish mainland and its islands in order to collect samples of wild populations of the genera Hordeum L., Taeniatherum Nevski and Hordelymus Jessen. This paper, which contains information garnered from both collection activities and the study of herbaria, describes the distribution and ecological characteristics of the habitats where populations of H. bulbosum, H. secalinum, H. murinum subsp. murinum, H. murinum subsp. leporinum, H. marinum subsp. marinum, H. marinum subsp. gussoneanum, Taeniatherum caput-medusae and Hordelymus europeus grow.The bioclimatic and geographical characteristics of the populations of the different genera and species from which samples were taken during collect ing expeditions are also described. 相似文献

为了证实长发带芒草中的y型高分子量谷蛋白亚基的存在,利用SDS-PAGE分析了3份长发带芒草的高分子量谷蛋白亚基组成,发现其y亚基的迁移率均较普通小麦中迁移率最快的D y12亚基迁移率更快,应用PCR扩增、序列测定及基因编码区体外表达等方法研究了1份材料中的y亚基,确认了长发带芒草比普通小麦中迁移率最快的D y12亚基迁移率更快的T ay亚基的真实存在及表达。研究结果证实带芒草属具有与普通小麦中相类似的y型高分子量谷蛋白亚基。 相似文献
