1Characterization of Gibberellin Receptor Mutants of Barley (Hordeum vulgare L.)显示文摘Gid1 的顺序(为赤霉素(GA ) 的基因从米饭的受体) 被用来从大麦识别通常认为的 orthologue。这在 E 被表示。coli,并且生产了能与结构的特性和 saturability 在 vitro 绑 GA 的蛋白质。它在 GA 回答的潜在的角色与减少的 GA 敏感(gse1 异种) 用大麦异种被调查。十六不同 gse1 异种各在这个序列带了唯一的核苷酸替换。在里面几乎一个案例,这些变化导致了单个氨基酸替换,并且,为留下的异种,在 mRNA 的 5 untranslated 区域的替换被建议防碍翻译开始。在分离有完美的连接在新变异的等位基因和 gse1 显型之间的人口,导致在大麦的通常认为的 GID1 GA 受体顺序对应于 Gse1 地点的结论。在异种之一的内长的 GA 内容的决心揭示了 C20 GA 先锋的 bioactive GA1,和赤字的提高的累积。所有在通常正在浸透的集中 gse1 异种把敏感归结为外长的 GA3,并且到 AC94377 (GA 类似物) ,,但是,在高得多的集中,经常有可观的回答。在大麦和米饭异种之间的比较揭示这之间的有趣的差别在 GA 的二谷物种神经质的生理学。Peter M.

2The tropical-subtropical evergreen forest transition in East Asia:An exploration显示文摘The transition from tropical to subtropical(warm temperate)evergreen forests is more clearly apparent in East Asia,fromNepal to the western Pacific coast,than elsewhere in the tropics.We review the nature of this transition and hypothesize the physical,ultimately climatic,factors thatmay maintain it,with a special focus on how the increasing instability and warming of climates will affect these forests.A primary climatic mediator of the transition is proposed,thereby offering a testable hypothesis for the climateeforest transition relationship.What is known of this transition is summarized in context of the primary climatic mediators of elevational zonation of forest formations in equatorial Asia to the tree line,in the Himalaya at the India-Indo-Burma northern tropical margin,and as both elevational and latitudinal zonation in southern China.Consequent secondary edaphic and other physical changes are described for the Himalaya,and hypothesized for southern China.The forest ecotones are seen to be primarily defined by tree floristic change,on which account changes in structure and physiognomy are determined.The montane tropical-subtropical transition in the Himalaya is narrowand observed to correlate with an as yet ill-defined frost line.A distinct tropical-subtropical transition forest is recognized in the southwest Chinamountains.There is a total change in canopy species at the Himalayan ecotone,but subcanopy tropical species persist along an elevational decline of c.400 m.The latitudinal transition in South China is analogous,but here the tropical subcanopy component extends north over ten degrees latitude,albeit in decline.The tropical-subtropical transition is uniquely clear in East Asia because here alone a tropical wet summer-dry winter monsoon extends to 35north latitude,encompassing the subtropical evergreen forest,whereas subtropical evergreen forests elsewhere exist under drier temperate summer climate regimes.Peter Ashton Hua Zhu 2020Plant Diversity2020,42,4:8
3中国热带-亚热带常绿阔叶林群落交错区显示文摘在中国南部热带北缘,热带森林向亚热带常绿阔叶林转变过渡,它们之间存在群落交错区.本文主要通过对中国热带北缘地区的4个永久样地植被的群落结构、生态外貌和植物区系组成分析,论证了热带-亚热带常绿阔叶林群落交错区的存在和其识别特征.由于中国南部西高东低的地势,西南部群落交错区主要体现在沿海拔的转变过渡,东南部则是沿纬度的转变过渡.西南部热带北缘存在两个明显的群落交错区.在海拔800~1200 m,热带低地季节性雨林与热带低山常绿阔叶林交错过渡,森林群落的外貌、结构和林冠层树种明显改变:由具有3个乔木亚层和散生巨树、典型混交热带树种组成林冠层的热带低地季节性雨林转变为具有2个乔木亚层、缺乏散生巨树、林冠趋于平整、主要由热带山地分布的壳斗科和茶科植物为林冠层优势树种的热带低山常绿阔叶林.在海拔1800~2100(2200)m,热带低山常绿阔叶林向亚热带常绿阔叶林交错过渡,林冠层树种发生了替换,群落的植物区系性质也发生了改变,由热带性质的植物区系变成亚热带-暖温带性质的植物区系.在中国东南部低地,约22°30′N及两侧附近,存在一个明显的常绿森林群落交错区:热带北缘低地季节性雨林向(南)亚热带低地常绿阔叶林交错过渡,群落的外貌、结构和林冠层树种明显改变.我们认为,热带-亚热带常绿阔叶林群落交错区与霜冻情况有关,霜冻对热带低地季节性雨林的林冠树种是致命的.我们建议,西南部的热带低山常绿阔叶林与亚热带常绿阔叶林的群落交错区和东南部的低地热带季节性雨林与亚热带常绿阔叶林的群落交错区为热带森林分布的北界.超越热带北界,林冠树种在西南部替换为亚热带-温带分布的中国-喜马拉雅和中国特有种,在东南部替换为主要是亚热带分布的中国特有种.中国东南部的亚热带气候地区存在热带植物区系成分,本文也对其原因进行了探讨,并提出了尚需进一步研究的问题.朱华 Peter Ashton 2021科学通报2021,66,28:7
4Tropical deciduous forest in Yunnan,southwestern China:Implications for geological and climatic histories from a little-known forest formation显示文摘In the southern mountain ranges of Yunnan province,China,deep valleys of several large rivers create rain shadows with hot dry summers,and are locally designated tropical;towards the north,notably in the Lancang(Upper Mekong)valley,these regions may experience frost during winter.The woody forest canopy of these valleys is predominantly deciduous,with evergreen elements in the north,where the canopy is open and the forest savanna-like.However,we here present tall forest with a closed deciduous canopy and semi-evergreen subcanopy observed in hot dry valleys of these rivers and their tributaries in the tropical south.The structure and physiognomy of these forests resemble the tall(moist)deciduous forest formation widespread in South Asia and Indo-Burma.Furthermore,these forests are largely composed of tropical elements at both the generic(80%)and the species level(>70%),indicating that these forests are indeed tropical.We originally hypothesized that these isolated forests represent refugia of a pre-Holocene extension of tall(moist)deciduous forest formation of South Asia and Indo-Burma.The sample plot we established to test this hypothesis confirmed that these forests share the structure and physiognomy of the tall(moist)deciduous forest formation;however,the plots also showed that these forests lack the characteristic and dominant species of the formation's Indo-Burmese range.The tree flora,in particular,indicates that both deciduous and evergreen elements are instead mostly derived from the adjacent tropical semi-evergreen forests of tropical southern China;yet they also include an important endemic element,which implies that these forests have survived as refuges possibly since the Pliocene.The exceptional representation of evergreen elements in these forests indicates that they have rarely been subject to hot fires or domestic cattle browsing,adding to the unique nature of the forests and further justifying their strict conservation.Hua Zhu Peter Ashton Bojian Gu Shisun Zhou Yunhong Tan 2021Plant Diversity2021,43,6:2
