Taxonomic notes on Metasasa and Indocalamus nanunicus (Poaceae: Bambusoideae)

Based on comprehensive field observations and careful herbarium studies, we discuss the status of the type species of Metasasa W. T. Lin (M. carinata W. T. Lin) and entities previously treated as synonyms of its name. Three species in two genera were involved. First, M. carinata and M. albofarinosa W. T. Lin were confirmed to be conspecific and a new combination Acidosasa carinata (Lin) D. Z. Li & Y. X. Zhang is proposed. Secondly, although M. carinata was previously treated as a synonym of Acidosasa nanunica (McClure) C. S. Chao & G. Y. Yang, close morphological study revealed that these two are not conspecific. Pseudosasa nanunica (McClure) Z. P. Wang & G. H. Ye is restored to accommodate this distinct species. Finally, another name previously treated as a synonym of A. nanunica, Pseudosasa acutivagina T. H. Wen & S. C. Chen should also be resumed. Synonyms are provided for each of these three species.     

斑苦竹学名的订正

作者研究了斑苦竹后认为, 当斑苦竹组合到青篱竹属Arundinaria 时, 其合法双名应为Arundinaria oleosa (Wen)C.S.Chao et G.Y.Yang。而Arundinaria chinensis C.S.Chao et G.Y.Yang 和Acidosasa lentiginosa W.T.Lin et Z.J.Feng 为斑苦竹的新异名。     

国产海桑属植物的两个杂交种

作者通过对红树林海桑属植物进行形态学、花粉学、细胞学以及其它方面的比较研究,证实了拟海桑和海南海桑为两个杂交种,它们的嫌疑亲本分别是杯萼海桑和海桑、杯萼海桑和卵叶海桑·ｓｏｎｎｅｒａｔｉａ×ｈａｉｎａｎｅｎｗｓｉｓｋｏ,ＥＹ．ＣｈｅｎｅｔＷ．Y　Ｃｈｅｎ（ｐｒｏｓｐ）为海南海桑的新名称,而拟海桑S．ｐａｒａｃｓｅｏｌａｒｉｓＫｏ,Ｅ.Ｙ.Ｃｈｅｎ,ｅｔＷ,ＣｈｅｎＹ.Ｃｈｅｎ则被归并入ｓｏｎｎｅｒａｔｉａ×ｇｕｌｎｇａｉＮ.C．Ｄｕｋｅ．     

中国铁角蕨属(铁角蕨科)一新名称

提出新名称 Asplenium dulongjiangense Y.F.Deng以代替晚出同名 Asplenium qiujiangense Chingex S.H.Wu non Nakaike,1 986。     

Gymnosporia thyrsiflora comb. nov. (Celastraceae), a correct name to replace G. graciliramula from southwest China

In ‘Flora of China’, the combination ‘Gymnosporia graciliramula (S. J. Pei & Y. H. Li) Q. R. Liu & Funston’ was proposed, but this name was not validly published in 2008 because the presumed basionym Maytenus graciliramula S. J. Pei & Y. H. Li was not published in 1979 as stated, but in 1981, contrary to Article 33.4 of ICBN. Meanwhile, two older names, M. thyrsiflora S. J. Pei & Y. H. Li and M. pseudoracemosa S. J. Pei & Y. H. Li, were listed as synonyms in conflict with article 52.3 of ICBN. In this article, we propose a new combination G. thyrsiflora (S. J. Pei & Y. H. Li) W. B. Yu & D. Z. Li that is the correct name when G. thyrsiflora, M. pseudoracemosa and M. graciliramula are treated as a single species in Gymnosporia.

TWO TYPES OF AUXILIARY CELL AMPULLAE IN GRATELOUPIA (HALYMENIACEAE,RHODOPHYTA), INCLUDING G. TAIWANENSIS SP. NOV. AND G. ORIENTALIS SP. NOV. FROM TAIWAN BASED ON rbcL GENE SEQUENCE ANALYSIS AND CYSTOCARP DEVELOPMENT1

Few species in the genus Grateloupia have been investigated in detail with respect to the development of the auxiliary cell ampullae before or after diploidization. In this study, we document the vegetative and reproductive structures of two new species of Grateloupia, G. taiwanensis S.‐M. Lin et H.‐Y. Liang sp. nov. and G. orientalis S.‐M. Lin et H.‐Y. Liang sp. nov., plus a third species, G. ramosissima Okamura, from Taiwan. Two distinct patterns are reported for the development of the auxiliary cell ampullae: (1) ampullae consisting of three orders of unbranched filaments that branch after diploidization of the auxiliary cell and form a pericarp together with the surrounding secondary medullary filaments (G. taiwanensis type), and (2) ampullae composed of only two orders of unbranched filaments in which only a few cells are incorporated into a basal fusion cell after diploization of the auxiliary cell and the pericarp consists almost entirely of secondary medullary filaments (G. orientalis type). G. orientalis is positioned in a large clade based on rbcL gene sequence analysis that includes the type species of Grateloupia C. Agardh 1822 , G. filicina. G. taiwanensis clusters with a clade that includes the generitype of Phyllymenia J. Agardh 1848 , Ph. belangeri from South Africa; that of Prionitis J. Agardh 1851 , Pr. lanceolata from Pacific North America; and that of Pachymeniopsis Y. Yamada ex Kawab. 1954, Pa. lanceolata from Japan. A reexamination of the type species of the genera Grateloupia, Phyllymenia, Prionitis, and Pachymeniopsis is required to clarify the generic and interspecific relationships among the species presently placed in Grateloupia.     

In vivo biosynthesis of vacuolar proteinases in proteinase mutants of Saccharomyces cerevisiae

The molecular forms of proteinase A, proteinase B and Car?ypeptidase Y, enzymes of the lysosome like yeast vacuole, were studied in mutants (Wolf,D.H. and Fink,G.R. (1975) J. Bacteriol. 123, 1150–1156;Wolf,D.H. and Ehmann,C. (1978) FEBS Lett. 92, 121–124;Mechler,B. and Wolf,D.H. (1981) Eur. J. Biochem. 121, 47–52) defective in genes, which appear to be structural genes of the respective enzymes. According to the immunochemical reactivity of proteinase protein, mutants could be divided into three classes: 1) Mutants harboring no immunoreactive proteinase material. 2) Mutants synthesizing proteinase precursor molecules of similar size as wild type, which are transferred into mature proteins, which are, however, completely inactive. 3) Mutants synthesizing proteinase precursor-like proteins, which are not processed into the mature proteins. As measured in the car?y-peptidase Y mutant strain the mutant precursor car?ypeptidase Y is rapidly degraded. A pleiotropic mutation (pep4-3) resulting in low activities of five vacuolar enzymes had been shown to accumulate pro-car?ypeptidase Y like immunoreactive material (Hemmings,B.A., Zubenko,G.S., Hasilik,A., and Jones,E.W. (1981) Proc. Natl. Acad. Sci. U.S.A. 78, 435–439). We found that this mutant is also defective in processing the proteinase B precursor, whereas no cross-reactive proteinase A molecule could be detected under the conditions employed.
