Leymus Racemosus, The Mammoth Wild Rye, Is A Rhizomatous Perennial Grass, Mainly Distributed In The Moving Or Semi-Stabilized Sand Dunes In Deserts Of The Junggar Basin In Xinjiang, China. The Revival Ability Of The Young Seedling After Periods Of Desiccation Can Be Influenced By Several Factors: (1) The Stage Of Seedling Development – The Later The Stage At Dehydration, The Longer The Root Length And The Lower Is The Percentage Of Seedlings That Survive; (2) The Length Of The Period Of Desiccation – The Longer The Period That The Seedlings Are Under Desiccation, The Lower Is The Percentage Of Seedlings That Survive; (3) Endosperm Size – The Smaller The Proportion Of Endosperm That Remains In The Caryopses, The Lower Is The Percentage Of Seedlings That Revive, Determined By (A) The Stage Of Seedling Development, And (B) The Proportion Of The Endosperm That Is Removed By Cutting; And (4) Caryopsis Size – The Larger The Polymorphic Caryopses, The Higher Is The Percentage Of Young Seedlings That Revive From Periods Of Desiccation. The Physiological And Ecological Implications Of L. Racemosus Seedling Desiccation Tolerance Are That Under Extreme Desert And Unpredictable Environmental Conditions, The Chances Of Seedling Establishment Are Increased.

Main Component

Climate is one of the most important factors determining the adaptive evolution of plants. In this study, 44 different populations of wild barley were used as materials to analyze the diversity of 17 genes (495 sequences), in order to study the influence of different climatic conditions on adaptive evolution of wild barley. A Geographical Information System (GIS) provided tools to visually present and analyse the geographical distribution of number of variable positions in the alignments and the differentiation index. 19 different bio factors were classified into 4 main component groups, and OLS Regression was used to analyze the differentiation coefficient of main climatic factors and the expression of gene differentiation degree. DHN family, a drought and temperature related gene family, showed significant spatial correlation with main climatic factors. Meanwhile, the results of other genes, which reported insignificant effects on drought or heat tolerance, were quite contrary. The phenotypes of plants were observed after the interaction of plant genotype with the environment. Simultaneously, the environment also has influence on some special genes. New analysis methods using GIS could be used to research the complex relationship between plant phenotype, plant genotype and the environment.
