查询词典 quantitative change

从蛋白质的氨基酸序列来预测它的三维结构是计算生物学和计算化学长期面临的挑战。研究人员40多年前就知道蛋白质的结构完全是由其氨基酸序列决定的，但是用序列信息来做结构的预测极为困难。

To determine the regulating role of mtlR in transcription of mannitol PTS operon in V.cholerae,and whether it plays a role in the ferment difference of the toxigenic and non-toxigenic strains,the mtlR deletion mutants from the mannitol rapid-ferment strain(non-toxigenic strain) and slow-ferment strain were constructed.Comparisons of the growth in M9 containing 0.2% mannitol as the sole carbon source and pH change in mannitol fermentation media of these wild strains and their mutants,indicated that mtlR is a repressor.Its repression in mtlCBA transcription was further verified with the analyses of quantitative reverse-transcriptional PCR.

通过比较快发酵菌株和慢发酵菌株mtlR缺失突变株与野生株在含0.2%甘露醇的M9培养液及甘露醇发酵液中生长、产酸等的变化，定性地证明了mtlR基因的抑制作用；另外通过定量RT-PCR进一步验证了MtlR蛋白在mtlCBA转录水平发挥负调控作用。

The spatial-temporal distribution of NPP along NECT and its response to climatic change were also analyzed. Results showed that the change tendency of NPP spatial distribution in NECT is quite similar to that of precipitation and their spatial correlation coefficient is up to 0.84 (P.01). The inter-annual variation of NPP in NECT is mainly affected by the change of the aestival NPP every year, which accounts for 67.6% of the inter-annual increase in NPP and their spatial correlation coefficient is 0.95 (P.01). The NPP in NECT is mainly cumulated between May and September, which accounts for 89.8% of the annual NPP. The NPP in summer accounts for 65.9% of the annual NPP and is the lowest in winter. Recent climate changes have enhanced plant growth in NECT. The mean NPP increased 14.3% from 1980s to 1990s. The inter-annual linear trend of NPP is 4.6 gCm^(-2)a^(-1), and the relative trend is 1.17%, which owns mainly to the increasing temperature.

结果表明：(1)NECT样带植被NPP的空间变化趋势同降水量的空间变化十分相似，由东到西逐渐降低，二者在空间上的相关性达到了0.84 (P.01)，说明NECT样带的植被NPP在空间分布上主要受水分趋动：(2)NECT样带植被NPP的年际变化主要是由各年份夏季NPP的变化造成的，夏季对NECT样带植被NPP的年际增长贡献率最大(67.6%)，二者之间的相关性达到了0.95 (P.01)；(3)NECT样带的植被NPP积累期主要发生在5-9月份，这5个月的NPP占了全年NPP总量的89.8%，整个夏季（6-8月份）的NPP占了全年的65.9%，冬季（12-2月份）的NPP最低，基本为0；(4)近19年来的气候变化促进了NECT样带的植被生长，从1980年代到1990年代，NPP显著增加，年代际相对增长率为14.3%，平均年际绝对增长趋势为4.6 gCm^(-2)a^(-1)，相对增长趋势为1.17%，这主要是由温度升高引起的。
