Chi竹属和牡竹属（竹亚科）叶表皮微形态特征

利用光学显微镜和扫描电镜,对Chi竹属21个种（包括Chi竹亚属5个种、孝顺竹亚属2种、单竹亚属4种绿竹亚属9种和亚属未定1种）以及牡竹属5种叶表皮微形态特征进行了观察和研究。所得结果表明气孔保卫细胞上乳突的数目和分布存在一定的规律,并具有一定的分类价值。绿竹亚属的叶表皮微形态特征界于Chi竹属和牡竹属之间,但更接近于Chi竹属。因此认为在分类处理上,将绿竹亚属置于Chi竹属比单独成立绿竹属更为合理。

Identity of a Chi site of Escherichia coli and Chi recombinational hotspots of bacteriophage λ

Chi sites in bacteriophage λ stimulate recombination promoted by the RecBC pathway of Escherichia coli. We have located a Chi site within the E. coli lacZ gene by deletion mapping and have isolated a mutation inactivating this Chi. Sequence analysis showed that the mutation arose by a single base-pair transition $\text{G}\text{C}\text{?}\text{→}\text{A}\text{T}\text{?}$ within an eight base-pair sequence (5′ G-C-T-G-G-T-G-G 3′) identical to that found at Chi sites in λ and in plasmid pBR322.     

Does Chi Give or Take?

In lytic cycle crosses with Red-Gam-lambda phage, particles were examined that had undergone an Int-mediated exchange. It was assumed that this exchange dimerized the circular lambda, making it packageable. Among these Int-mediated recombinants, particles were identified that had, in addition, enjoyed a close double exchange mediated by the RecBC pathway. Such close double exchanges indicate localized negative interference and are analogous to eukaryotic conversions that have retained parental configuration of flanking markers. These events are stimulated by Chi, a recombinator specific to the RecBC pathway. When Chi is present in only one parent in the cross, the complementary double exchange recombinants are Chi stimulated to the same degree. This behavior of Chi contrasts with that of characterized eukaryotic recombinators.
