bydv 中文意思是什麼
bydv
解釋
黃矮病毒-
Barley yellow dwarf virus often leads to a serious loss in the yield of wheat. but at present, we have not find excellent genes resistant to bydv in wheat, so transferring the excellent genes from relatives to cultivars of wheat will be a good method
因此，植物耐鹽、耐黃矮病、耐蚜蟲等機理和相應耐性植物的培育，乃至相應耐性相天基因的分離與克隆及其基因工程育種的研究正在受到人們越來越多的關注。 -
The pap gene was also transformed into wheat by pollen tube pathway - mediated and 320 grains of transgenic wheat was harvested. the seedlings of the seeds were inoculated with the gav isolate of barley yellow dwarf virus ( bydv ) by schizaphis graminum ( rondani ) and the results revealed that 33 wheat seedlings did not produce the symptom or the symptom was very mild
通過花粉管通道法將pap基因導入小麥，收獲了轉基因小麥種子320粒，將其播種，返青后，直接用麥二叉蚜將大麥黃矮病毒（ bydv ） gav株系接種到幼苗葉片上，觀察發病情況。 -
High - level expression of bydv gav coat protein gene in escherichia coli
株系外殼蛋白基因在大腸桿菌中的高效表達 -
The leymus multicaulis has many excellent traits, such as immune or highly resistant to bydv, and highly tolerant to salt and aphid, which are controlled by some unknown genes
這些特性都是目前種植的大多數農作物、牧草與草坪草栽培品種，本身缺乏急需改良的特性。因此，分離克隆控制這些優異抗逆特性的功能基因，非常必要。 -
One of them is line24 which is tolerant to bydv and aphid when inoculated with aphid which take gav strains. the other is line 14 which is tolerant to salt when treated with 1 % nacl solution. the result showed that fourteen fragments which is only expressed in disomic addition line - line 14 and twelve fragments only expressed in disomic addition iine - line24 were obtained
在表現差異的條帶中，共分離得到了12條line24特異表達條帶，其中8條是有毒蚜誘導下的帶， 3條是有毒蚜、無毒蚜和不接蚜蟲處理下均表達的帶， 1條是有毒蚜和無毒蚜處理下均表達的帶；也獲得10800條耐鹽材料cdna擴增條帶，其中89 . 5在不同處理條件下是非常一致的。
