从青春期到泌乳期以至干乳期,奶牛乳腺经历复杂的生物学功能和代谢水平的变化.通过基因芯片分析奶牛乳腺的基因表达谱,通过泌乳旺盛的泌乳期与不泌乳的青春期和干乳期相比较,共筛选出122个差异表达的基因,其中包括79个泌乳期上调基因和43个泌乳期下调基因.GO分析表明,在泌乳期奶牛乳腺中上调的基因主要与物质转运、生物合成、信号转导、催化活性、免疫防御、细胞凋亡以及促进发育相关.这些数据提示了奶牛乳腺泌乳期所发生的分子事件.

中国自1997年便开始大面积种植Bt抗虫棉.本研究试图分析中国种植抗虫棉10年后减少防治棉铃虫杀虫剂用量的可持续性.通过对1999~2007年4个省16个村农户大田Bt抗虫棉生产的跟踪调查数据分析,发现生产上控制棉铃虫的杀虫剂用量不仅未增加,反而呈下降趋势;虽然没有直接回答Bt抗虫棉能够维持并增加其生产率的机理,但本研究发现,10年来不仅抗虫棉,而且非抗虫棉防治棉铃虫的杀虫剂用量也显著减少,这与抗
