解釋
能育花粉-
Abstract : the main characters and seed set of bc1 ， bc2 ， bc1f2 from ms line back - crossing with the pollen of hybrid rice were studied. the appearance of a large number of self fertile plants in ms line was analyzed. the effect of introgression of restoring genes on ms line purity and hybrid yield in indica and japonica rice was discussed. it was pointed out that “ iso - cytoplasm restorer line ” was seriously reducing the purity of ms line and that hybrid rice was unsuitable for isolation zone in the seed production fields
文摘:研究了雜交稻花粉對母本不育系回交後代群體bc1 、 bc2 、 bc1f2的主要農藝性狀和育性表現，分析了不育系中出現大量自交結實株的原因，討論了恢復基因滲入對秈、粳不育系純度和雜交稻產量的影響，指出「同質恢」對降低不育系純度的嚴重性和雜交稻作制種田隔離區的不合理性。 -
Varieties that do not produce fertile pollen are used as females.
不產生可育花粉的品種被用作母體。 -
Dong a, the male sterile line of cotton discovered in 1972 from a pollenless mutant of cotton variety dongting no. l, is an ideal materials used to study the pollen - specific genes during anther development. the fertile individuals and its pollenless mutant have a highly homogeneous genetic background except for the male sterility
棉花洞a雄性核不育系是1972年從洞庭一號棉花原種圃中發現的突變體，不育度高且穩定，可育與不育花粉在單核期以前發育同步，是研究棉花花藥與花粉發育相關基因的理想材料。 -
Expression analysis the expression analysis of gharf in different tissues of cotton was carried out by rna dot blotting with ghakf probe labeled with dig. the result showed that the expression of arf gene was mainly in anthers of sterile and fertile, pollen of fertile, corolla rather than in leaves, radicel and ovule
棉花ari ； 』基因的表達分析用地高辛將棉花arf基因標記為探針，與棉花洞a的不育株花藥、司有株花藥、可育花粉粒、葉片、花冠、胚根和胚珠的總rna進行斑點雜交。 -
The paraffin section analysis showed that there were no difference between transgenic sterile plants and control fertile plants in the development and structure of pollen sac. in order to analyze the sterility mechanism further, we handled the pollen mitochondria in normal temperature and heat shock response, then we extracted the mitochondrion proteins and make variance analysis
石蠟切片分析表明，轉基因不育植株的花粉囊的發育和結構與對照的可育植株之間沒有任何差異，只是花粉囊中的花粉在不育株中是不育的，而可育株是可育的。
