技术领域
本发明属于基因工程技术和果实采后病害生物防治技术领域,涉及盔形毕赤酵母(Pichia galeiformis)Thioredoxin类分泌蛋白及其应用。
背景技术
拮抗酵母是果实采后病害防治中常用的生物防治拮抗菌。已有大量文献报道拮抗酵母能诱导果实抗病性,涉及果实多种抗病基因的表达、激素合成和信号转导途径、抗病相关物质的合成等。然而,拮抗酵母分泌蛋白对果实抗病性的作用还不清楚。
柑橘是芸香科柑橘亚科柑橘属植物,是世界和中国产量最多的水果。新鲜柑橘果实在采后运输、贮藏等过程中极易受微生物侵染,损失可达总产量的30%以上。由真菌指状青霉(Penicillium digitatum)引起的绿霉病是柑橘果实贮藏过程中主要的侵染性病害。目前产业上主要采用咪鲜胺等化学杀菌剂控制果实采后病害,但存在杀菌剂残留、微生物产生耐药性等问题。

4.含有上述重组表达载体的工程菌。
进一步,所述工程菌是将含有盔形毕赤酵母Thioredoxin类分泌蛋白编码基因的重组表达载体转入农杆菌GV3101中而得到。
5.盔形毕赤酵母Thioredoxin类分泌蛋白在制备诱导柑橘果实抗病性的保鲜剂中的应用。
进一步,所述诱导柑橘果实抗病性为诱导柑橘果实绿霉病抗病性。
6.所述工程菌在制备诱导柑橘果实抗病性的保鲜剂中的应用。
进一步,所述诱导柑橘果实抗病性为诱导柑橘果实绿霉病抗病性。
本发明的有益效果在于:本发明提供了盔形毕赤酵母Thioredoxin类分泌蛋白及其在制备诱导柑橘果实抗病性的保鲜剂中的应用,研究结果证实,农杆菌介导的遗传转化在柑橘果实上瞬时表达Thioredoxin类分泌蛋白,能一定程度抑制柑橘果实绿霉病的发病和病斑直径的增长。本发明从盔形毕赤酵母中挖掘出具有诱导柑橘果实抗病性的Thioredoxin类分泌蛋白,不仅丰富了盔形毕赤酵母诱导柑橘果实抗病性的机理,拓宽了拮抗酵母在果实保鲜领域的应用方式,也为柑橘果实采后绿霉病的防治提供了新的解决方法。
