  黄萎病是棉花生产中最具毁灭性病害之一,种植抗病品种是控制该病害最为有效途径之一.本试验通过花粉管通道法将hpa1Xoo基因导入陆地棉品系854,经多代选育获得了可稳定遗传表达hpa1Xoo基因且农艺性状稳定的2个棉花材料854-3和854-5.转hpa1Xoo基因棉花具有出苗快,长势较好,整齐度高;植株中等,株型松,茎秆毛少光滑,叶片大,叶色深绿,叶功能较好,结铃性较强,铃桃形,较大,吐絮畅的特点.

甜菜坏死黄脉病毒(Beet necrotic yellow vein virus,BNYVV)是甜菜丛根病的病原,由4-5条+ssRNA组成,其中RNA3编码的p25蛋白是BNYVV在甜菜上的关键致病因子,参与病毒在根中的复制与转移,与病毒侵染后的"毛根"症状相关.当接种毒源中含有野生型RNA3时,就会出现典型的丛根症状,并导致甜菜根重降低95%,病毒浓度提高10-20倍,而当接种毒源中含有RNA
