1Transfer of bacterial blight resistance from Oryza meyeriana to O. sativa L. by asymmetric somatic hybridization显示文摘Asymmetric somatic hybrid plants were pro-duced between cultivated rice (Oryza sativa L.) and wild spe-cies [O. meyeriana (Zoll. etMor. exSteud.)] with high resis-tance to rice bacterial blight. X-ray-irradiated protoplasts of the wild species were used as donor and chemically fused with iodoacetamide-inactivated protoplasts of rice cv. 02428 to produce hybrids. Seventy-two plants were regenerated from 623 calli based on metabolic complementation. The morphological characters of the plants closely resembled that of the rice. Simple sequence repeats were employed to iden-tify their hybridity. Cytological analysis of root-tips revealed that their chromosome number varied in the range of 27— 38. The somatic hybrids were inoculated with strains of Xanthamonas oryzae pv. oryzae at adult growth stage and demonstrated the resistance to bacterial blight introgression from the O. meyeriana.ZHUYongsheng CHENBaotang YUShunwu ZHANGDuanpin ZHANGXueqin YANQiusheng 2004Chinese Science Bulletin2004,49,14:6

3Primary report on the plant regeneration from rice protoplasts incorporated with diazotroph显示文摘In our experiment the protoplasts of wide com-patible rice variety 02428 isolated from cell suspen-sion were used.The diazotroph Alcaligenes faecalisstrain A15H1 was selected for incorporation intorice protoplast.A.faecalis A15H1 is an associativediazotroph isolated from rice roots in South China.It can utilize and assimilate CO_2 as the soleSONGWei WANGYaodong ZHANGXuetao YOUChongbiao YANQiusheng ZHANGXueqin 1991Chinese Rice Research Newsletter1991,,2:0
4Somatic hybridization between rice and ap.omictic Panicum显示文摘Protoplasts from suspension-culture cells of japonica rice cultivar 02428 (Oryza sativa L.)were inactivated with 2.5 mM indoacetamide (IDA) at room temperature (22-25℃) for 15 minutes before fusion. The nonmorphogenic protoplasts from suspension culture of apromictic Panicum maximum Jacq. were treated with 60 Kr soft X-ray or with no treat ment. These inactivated protoplast mixtures were fused by electrofusion or PEG method and incubated. After incubation, over 50 putative rice cybrids plantlets were obtained. A mong them, 28 regenerated plants were vigorously growing and flowering. Comparing with the original rice parental plants, these fusion-cell derived plants have remarkahle variation in morphology and structure on the flower organ. In most plants, the number of anthers was increased, ranging from 7 to 13 and the number of stigma or ovary was increased, ranging from 3 to 6 on a single flower(see fingure). In some plants, the fiumber of ovule in a single ovary or the embryo sac in a single ovuleYANQiusheng ZHANGXueqin TENGSheng SUNJingsan XINHuawei 1995Chinese Rice Research Newsletter1995,3,4:0
5Observation on ultrastructural change of embryogenic suspension cells cryopreserved by vitrification in rice(Oryza sativa L.)显示文摘Vitrification is a new approaeh for cryopreservation, which could avoid damages due ro ice formation and solution effects occurring under conventional methods.WANGJunhui LUIFeng HUAGChannong YANQiusheng ZHANGXunqin 1998Chinese Rice Research Newsletter1998,6,2:0
