良种是提高棉花产量的基础。随着科学种田水平的提高,人们对品种的认识和需求越来越迫切。目前,棉花三圃繁殖良种方法,已不适应棉花生产中品种多、周期短的新形 Good seed is the basis for increasing cotton yield. With the improvement of the level of scientific farming, people’s understanding of and demand for varieties are more and more urgent. At present, the method of breed of fine breeds in three nurseries of cotton has not adapted to the new breed with short cycle in cotton production

桦褐孔菌(Inonotus obliquus)是一种十分珍稀而名贵的野生药用真菌,其药用部分为菌核。目前虽然很多学者已成功人工驯化栽培桦褐孔菌,并能够形成菌核,但其生物学效率过低,严重地限制了桦褐孔菌的规模化生产。为了从分子水平研究影响菌核产量的因素,本研究采用RACE技术首次克隆得到桦褐孔菌酸性蛋白酶基因(IO-AP),对该基因进行生物信息学分析,并对该基因进行原核表达与多克隆抗体制备,结果如下
