Degenerate oligonucleotides to highly conserved regions of cucumis melo 1 - aminocyclopropane - 1 - carboxylic acid ( acc ) oxidase gene were used to prime the amplification of fragment of 128bp by ploymerase chain reaction ( pcr ) in samples of genomic dna from fruit of cucumis melo l. cv hetao flesh, which was cloned into plasmid vector pmd - 18 - t. the clon of antisense orientation were selected, and it was inserted downstream of camv35s promoter and enhancer " " of tmv into the plant expression vector pbinyxw, antisence expression vector pbinya was constructed. at the base that pollination and fertilization of cucumis melo l. cv hetao was studied, using pollen tube pathway transformate cucumis melo l. cv hetao, 76 fruit had been obtained, moreover, hardness and content of sugar were analysed
本實驗以河套蜜瓜果肉基因組dna為模板，用甜瓜acc氧化酶基因特異寡核苷酸鏈為引物進行pcr擴增，得到128bp的擴增產物。將得到的擴增產物克隆到質粒載體pmd - 18 - t上，篩選反向克隆，然後將其反向構建到植物表達載體pbinyxw的camv35s啟動子和tmv增強子「 」的下游，構建成反義表達載體pbinya 。並在對河套蜜瓜授粉受精生物學研究的基礎上，通過花粉管通道法轉化河套蜜瓜，共獲76顆瓜，並進行了硬度和含糖量的分析。Enclosure of the nucellus by the integuments is incomplete, the embryo sac or, in gymnosperms, to the archegonium
珠被並不是將珠心完全封閉，而是留有珠孔以便受精時花粉管進入胚囊，或裸子植物的藏卵器。In this paper, observation was conducted on pollen germination and growth behavior in distant hybridization between cerasus fruticosa and c. avium and hybridization between varieties in c. fruticosa through fluorescent light system of microscope. the results showed that pollens could normally germinate and pollen tubes could reach ovary through style to completed fertilization in intraspecific hybridization in c. fruticosa. the average fruit - set rate was 27 %
