Abstract Paeonia decomposita Hand.‐Mazz. subsp. rotundiloba D. Y. Hong is here raised to the specific rank, P. rotundiloba (D. Y. Hong) D. Y. Hong, based on its distinctiveness of four diagnostic characters: number of carpels; height of disk; number of leaflets of the lower leaves, and shape of the terminal leaflets; and unpublished molecular data. Paeonia rotundiloba differs distinctly from P. decomposita in having carpels mostly 3, less often 2 or 4, very rarely 5 (vs. almost always 5, very occasionally 4 or 3), disk 8–15 mm high (vs. 4–9.6 mm), leaflets mostly 19–39 (vs. 29–63) in number, and ratio of length to width of the terminal leaflets 1.09–1.93 (vs. 1.81–2.99). 相似文献

THE ESTIMATION OF SULPHATE-REDUCING BACTERIA (D. DESULPHURICANS) 总被引:3,自引:3,他引:0
SUMMARY: Sodium sulphide or cysteine stimulated the growth of sulphate-reducing bacteria; small populations often did not grow without such supplements. Ascorbic acid, glutathione or thiolacetic acid had similar properties but thiolacetic acid was sometimes inhibitory, Dilution counts in liquid media or colony counts in agar media did not bear any regular relation to the total count unless one of these supplements was present. With suitable precautions colony counts reaching 50 to 60% of the total count were obtained in media incorporating cysteine and a ferrous salt (as an indicator of sulphide formation).
Samples of natural origin containing sulphate-reducing bacteria gave greater viable counts in cysteine-iron media than in unsupplemented media. Blackend culture tubes with natural populations were sometimes due to cysteine-decomposing organisms; further examination of positive tubes was therefore necessary. 相似文献

The diversity of immunoglobulins and T cell receptors is largely due to the assembly of functional genes from separate segments. The mechanism by which these gene fragments are joined is starting to be deciphered, with broken DNA molecules that may be intermediates in the reaction providing a new clue. 相似文献
