糜子

Broomcorn millet playsan important part in grain production. Because of its high yield it caneven help to tide over faminein years of crop failure.

对糜子比较耐旱的特性进行了生物学方面分析，物候学方面的分析及地理分布方面的分析，说明糜子在宁南山区仍有较大的增产潜力。

Exploring novel genes and gene combinations are of primary importance in plant drought-tolerance and water-saving research. Based on the EST sequence of MYB gene obtained in the research on molecular basis of drought-tolerance and water-saving in broomcorn millet Panicum miliaceum L.

根据在糜子抗旱节水分子基础研究中获得的一个糜子 MYB 基因的EST序列，以其序列及水稻MYB18基因的序列为基础设计引物，扩增得到1 739 bp的全长基因组序列。

PmMYB has the highest similarity (84%) with MYB18 gene of rice, whereas 46% and 41% with barley and corn, respectively. Semi-quantitative RT-PCR confirmed that PmMYB was upregulated by water stress and re-watering in broomcorn millet.

通过半定量RT-PCR对其表达模式分析表明，该基因在水分胁迫和干旱后复水条件下上调表达，与糜子抗旱节水紧密相关。

Through biological, phenological, geographical and distributionalanalyses of drought resistance and tolerance of broomcorn millet, it canbe seen that this crop has a good yield potentialin south Ningxia. Inthe last part of the paper the author ...

最后对提高糜子生产提出如下几点建议： 1、加强对糜子的科研工作，特别要注意高产栽培的研究； 2、在品种普查基础上，对宁南山区的糜子品种资源进行一次收集整理工作； 3、种子部门应繁殖经营糜子品种，特别要留足小日月救灾品种； 4、大力推广固原县鸦儿沟生产队糜子高产经验； 5、用少量尿素作种肥，增产显著，可普遍采用。

PmMYB is a typical R2, R3-MYB transcription factor with its 2 typical DNA-binding domains (amino acid sites of 13-63 and 66-114).The multiple alignment of R2, R3 amino acid repeat regions of MYB genes among broomcorn millet, rice, corn, loblolly pine, Arabidopsis, capsicum, upland cotton, barley and aubergine indicates that R2, R3 repeat regions are very conserved. The phylogenetic analysis based on amino acid sequence shows that MYB genes are highly divergent with similarity ranging from 32% to 84%.

对其与水稻、玉米、火炬松、拟南芥、辣椒、陆地棉、大麦及茄子等9种植物的 MYB 基因的R2、R3重复区的氨基酸序列多重比较，表明R2R3重复序列在植物中具有较高的保守性；基于氨基酸序列的编码区系统进化树分析表明，不同植物的MYB基因遗传分化很大，序列相似性为32%~84%，其中糜子 MYB 基因与水稻的 MYB18相似程度最高(84%)，与大麦和玉米的相似性分别为46%和41%。

In this paper it is pointed out that broomcorn milletis one of staplecrops in the mountain areas of south Ningxia.

本文指出，糜子是宁夏南部山区的主要作物之一，在粮食生产中占有重要地位，在个别年份甚至起着稳产救灾的作用。

The results showed, in the rain-fed agriculture, slowing leaves ageing is vital important to promote grain filling and increase jield and quallty of Panicum miliaceum L.

研究认为，在旱作农业生产中，延缓叶片衰老，对促进糜子籽粒充实，提高糜子产量和品质具有重要作用。

In order to study the quality properties quickly test method of broom corn millet, this test used near infrared spectral analysis technology to determine the content of thick albumen of 73 broom corn millets.

为了研究糜子蛋白的快速测定方法，本试验应用近红外光谱分析技术测定73份糜子粗蛋白含量。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
