The results show that: double and heavy machine-plucking increase bud density and one-leaf and one-bud yield in autumn. They also remarkably decrease bud weight, length and fitting ratio for processing of Bailumaojian tea. Among the 4 treatments, light machine-plucking has the largest one-leaf and one-bud yield fitting for processing famous Bailumaojian tea. Chemical analysis shows that leaves of four treatments are all fit for processing famous Bailumaojian tea, while those of no machine-plucking treatment have the best organoleptic quality.

①Location of WD gene in Ch inese: Using pairwise linkage analysis and multipoint linkage analysis method, w e constructed a genetic map of DNA markers within D13q14.2-3 which refined the location of WD gene by restriction fragment length polymorphism and microsatellite polymorphism analysis;②Screen for mutations of WD gene in Chinese people: we detected the structure of 21 exons of WD ge ne in 45 patients from 39 pedigrees by PCR-SSCP(Single strand conformation poly morphism) and PCR-DNA sequencing technology, found a new mutation in exon 5 and nuclcotide sequence analysis showed it is a T insertion. We also conformed the Arg778Leu in exon 8, the highest frequence mutation point in Chinese people, wit h mutation rate 22.8%in total;③Carrier detection and presymptomatic diagnosi s of WD: Based on DNA recombination technology, we peformed successfully the gen e diagnosis in all individuals of 79 families with WD and built up a helpful spe cific enzyme cut method (PCR-Msp1) to detect the carrier and presympomatic patients in Chinese pe ople with WD.

Results as bellows: AtSIRT1 was located in Mitochondrial as hSIRT4 of human, and maybe take part in respiration and electron transformation chain, AtSIRT2 was located in nucleolus as hSIRT6 of human, maybe play important role in extend lifespan;mutation in AtSIRT1 leaded to cotyledon of plant turn to yellow and caused short life span. Mutation in AtSIRT2 could make the color of leaf turn to purple and accumulate a lot of anthocyanin;Sirtinol, a inhibitor of SIRT which did not cause the same model of the mutation of AtSIRT1 and AtSIRT2 indicated that the mechanism of Sirtinol was different from other organism;the structure of AtSIRT1 and AtSIRT2 were similar to other known Sir2, which indicated that they maybe have the same function;AtSIRT2 was overexpressed and its activity was detected.

结果表明，1，拟南芥AtSIRT1与人的同源蛋白hSIRT4相同，定位于线粒体，可能参与呼吸作用和电子传递，SIRT2与人的同源蛋白hSIRT6相同，定位于细胞核，可能同它的功能类似，在延缓衰老及调节细胞寿命方面起作用。2，AtSIRT1突变，可引起幼苗和植株的子叶变黄和早衰；AtSIRT2突变，可引起叶片发紫，沉积大量花青素。3，SIRT蛋白的抑制剂Sirtinol不能表型模写AtSIRT1和AtSIRT2突变体，说明Sirtinol在拟南芥中的作用机制不同于其他生物。4，AtSIRT1和AtSIRT2蛋白质结构预测表明与已知的Sir2蛋白相似，揭示其功能的相似性。5，在大肠杆菌中过量表达了其中一个基因(AtSIRT2)，可体外检测其酶学活性，进一步证明其功能。
