For searching out male sterility-related proteins (polypeptides) in rice(Oryza sativa L. ), we examined the difference of panicle protein (polypeptides) between hybrid rice( Wujin2A/R168, Wujin5A/R988) and their parents (male-sterile line Wujin2A, Wujin5A, and restorerline R168, R988) at the formation stage of pollen mother cell by two-dimensional electrophoresis(2-DE). The results revealed that the 2-DE polypeptide maps were similar among these experimentalmaterials. A small group of polypeptides were disappeared in 2-DE polypeptide maps of male-sterileline (Wu-jin2A, WujinSA) by comparing to restorer line (R168, R988) and the first filial (F, )generation (Wujin2A/R168, Wujin5A/R988). The isoelectric points of these polypeptides were pl5.8-6.5, molecular weight 42. 7 X 10~3-66. 2 X 10~3. 展开更多

This study aimed to study whether the Sortase A(srt A)gene helps mediate coaggregation and co-adherence between Streptococcus mutans(S.mutans)and other salivary bacteria.S.mutans UA159 and srt A-deficient mutant served as"bait"in classical co-aggregation assays and membrane-based co-adherence assays were used to examine interactions of S.mutans with Fusobacterium nucleatum(F.nucleatum),Streptococcus mitis(S.mitis),Streptococcus gordonii(S.gordonii),Streptococcus sanguis(S.sanguis),Actinomyces naeslundii(A.naeslundii)and Lactobacillus.Co-adherence assays were also performed using unfractionated saliva from healthy individuals.Co-adhering partners of S.mutans were sensitively detected using polymerase chain reaction-denaturing gradient gel electrophoresis(PCR-DGGE).Both UA159 and its srt A-deficient mutant bound to F.nucleatum but not to any of the other five salivary bacteria.The srt A-deficient mutant showed lower co-adherence with F.nucleatum.The two S.mutans strains also showed similar co-adherence profiles against unfractionated salivary bacteria,except that UA159 S.mutans but not the srt A-deficient bound to a Neisseria sp.under the same conditions.Deleting srt A reduces the ability of S.mutans to bind to F.nucleatum,but it does not appear to significantly affect the binding profile of S.mutans to bulk salivary bacteria. 展开更多
