简介:瑞斯耕作长被认为从在某处在画热带野米饭的年度类型播种发源,热带或在长江盆。然而,当我们认为巨大的困难让原始的人在温暖、潮湿的气候播种任何谷物庄稼时,那个想法包含一个毁灭性地弱的点,在杂草全年繁荣的地方。而不是接受理论,我们不得不看见可食的植物的植物的繁殖是在如此的区域的农业的一种主导的形式的现实。可能性被讨论那个工作的眼泪和米饭,对这个区域唯一的二谷物庄稼,可能经由植物的繁殖被开发了在谷物生产以前在后院花园里为药或植物茶获得材料。这个想法被在适度的区域的米饭在它的生长习惯仍然是长期的并且有移植芋头的如此的后院花园能仍然从中国的云南省被看见到老挝的事实支持。由于在整个为19701980的中国的野米饭的详细调查,野米饭的一套克隆在江西省在浅沼泽地存在,这现在被证实,有严重冬季的一个区域冷。在早夏天,古老的农民可能划分了发芽的芽并且由移植进充满的浅沼泽地散布了他们。繁殖力量的如此的方法更快比的为对人的干扰的反应通过一个更好基因的潜力改进了不太高效的大米在种子繁殖的快固定,因为植物的部分是异构的。显然,大米耕作的如此的一种原始方式确实包括了大米耕作的必要部分,即,托儿所床,在浅沼泽地的充满的地里移植象一样。到由种子的真托儿所的从原始托儿所的转移以后可能允许米饭耕作被延长到北区域。在因此设计的充满的耕作,有一系列唯一的优点,即;在一个一样的阴谋的大米的连续收割,没有土壤侵蚀,土壤富饶的慢衰落,矿物质的可获得性,并且每统一区域导致高产量,它一起在温暖、潮湿的区域达到了高度高效的谷物耕作。在沼泽地的瑞斯耕作也是有利的提起鱼文化,哪个组成了一个营养地平衡的底。到充满的�

简介:植物蛋白质蛋白质相互作用网络没被大规模实验识别了。以便更好在米饭理解蛋白质相互作用,预言的米饭Interactome网络(PRIN;http://bis.zju.edu.cn/prin/)介绍76,585个预言的相互作用包含5,049米饭蛋白质。在印射米饭的genomic特征以后(去注解,subcellular本地化预言,和基因表示),我们发现一个注解得好、生物学上重要的网络是足够富有的在高顺序的生物系统以内捕获许多重要功能的连接,例如小径和生物进程。而且,我们作为例子拿了疯盒子的包含域的蛋白质和生理节奏的节奏发信号小径证明功能的蛋白质建筑群和生物小径能有效地在我们的预言的网络被扩展。在PRIN的扩展分子的网络更加改进了这些分析的能力集成存在知识并且提供新奇卓见进基因和基因网络的功能和协作。
