  1. Cryptic species have been found in a wide range of marine organisms ; with majority of them are benthic invertebrates. in contrast, marine holoplanktons are thought to have lower diversity and slow speciation due to their strong dispersal potential. this paper reviewed studies on cryptic species and speciation in marine holoplankton. based on findings in 38 studied taxa, it was concluded that : 1 ) cryptic species are pervasive in marine holoplankton, suggesting holoplankton speciation was more active than previously thought ; 2 ) current morphospecies diversity is untenable to reflect true species diversity in marine holoplankton ; 3 ) geographic isolation may facilitate cryptic speciation of marine holoplankton. however, contribution of allopatric speciation is still questionable ; 4 ) ecological speciation may be the prevailing speciation mode in marine holoplankton. cryptic speciation in marine holoplankton is paradoxical, because rapid speciation under strong gene flow is countertuitive. solution of this paradox will help us gain deep insights of marine speciation and biodivesity

    隱種廣泛存在於各類海洋生物中,尤其是底棲無脊椎動物.然而,海洋終生浮生物由於具有較強的擴散能力,往往被視為生物多樣性低、物種形成慢.本文就海洋終生浮生物隱種與物種形成的研究作一綜述.於研究的38個種類,結果表明: 1 )海洋終生浮生物普遍存在隱種,其物種形成要比想象得快; 2 )由於引種的廣泛存在,形態種生物多樣性無法反映海洋終生浮生物真正的物種多樣性; 3 )地有助於海洋終生浮生物隱種的形成,但異域物種形成的作用仍值得商榷; 4 )生態物種形成很可能是海洋終生浮生物物種形成的主流模式.海洋終生浮生物強因流下快速的物種形成有悖于生物進化常,解決該悖將有助於我們對海洋物種形成和生物多樣性的
  2. Abstract : plant responses to salt stress via a complex mechanism, including sensing and transducing the stress signal, activating the transcription factors and the corresponding metabolizing genes. since the whole mechanism is still unclear, this review emphasize the biochemical events during the plant adaptation to salt stress referring to an index of importance : the homeostasis in cytoplasm, the biosynthesis of osmolytes and the transport of water. most of these biochemical events were elucidated by study of halophyte and salt - sensitive mutations, also many important genes involved were cloned and used to generate stress - tolerance phenotypes in transgenic plants. on the other hand, about the molecular mechanism in signal transduction, the research of arabidopsis mutations and yeast functional complementation provided helpful traces but not full pathway

    摘要植物對鹽脅迫的耐受反應是個復雜的過程,在分子水平上它包括對外界鹽信號的感應和傳遞,特異轉錄因子的激活和下控制生生化應答的效應因的表達.在生化應答中,本文著重討負責維持和重建子平衡的膜轉運蛋白、滲調劑的生物合成和功能及水分控制.這些生生化應答最終使得液泡中子濃度升高和滲調劑在胞質中積累.近年來,通過對各種鹽生植物或鹽敏感突變株的研究,闡明了許多鹽應答的子轉運途徑、水通道和物種特異的滲調劑代謝途徑,克隆了其相關因並能在轉因淡水植物中產生耐鹽表型;另一方面,在擬南芥突變體及利用酵母鹽敏感突變株功能互補篩選得到一些編碼信號傳遞蛋白的因,這些都有助於闡明植物鹽脅迫應答的分子機制。
