查询词典 drought-stricken

Thischaracteristic of Atriplex canescens is consistent with that of many local species. TheLCP of Atriplex canescens in different treatments (light, medium, no and heavy watersoil stress) are 314.8μmolm~(-2)s~(-1)、272.5μmolm~(-2)s~(-1)、176.7μmolm~(-2)s~(-1)、143.1μmolm~(-2)s~(-1), respectively, which indicates that the LCP of Atriplex canescens is reducingwith the escalation of soil water stress. This tendency is favorable for Atriplexcanescens under drought stress to maintain certain photosynthesis even in weaksunlight so as to ensure the survival of itself, and keep balance between maintainingwater content inside and its photosynthesis.

四翅滨藜在不同土壤水分胁迫下的光补偿点：轻度土壤水分胁迫、中度土壤水分胁迫、无土壤水分胁迫和重度土壤水分胁迫下的光补偿点分别为，314.8μmolm~(-2)s~(-1)、272.5μmolm~(-2)s~(-1)、176.7μmolm~(-2)s~(-1)、143.1μmolm~(-2)s~(-1)，说明四翅滨藜的LCP随着土壤水分胁迫的加重而呈现降低的趋势，这种变化有利于处在干旱胁迫中的四翅滨藜在光强较弱的条件下仍然能维持一定的光合作用，以满足植物自身生命活动所需，同时也可以使植物在保持体内水分和进行光合作用之间寻找平衡。

Atriplex canescens is an evergreen shrub introduced from the United States. Trials onits ecophysiological and drought-resistance features were conducted.

The trials on cultivation of Atriplex canescensconducted in Minqin Desert Control Experiment Station reveals that this speciesentails fine qualities as strong tolerance in drought, cold, salinity and low temperatureas well as high annual biomass. So it cab be extended in sandy areas with favorableirrigation condition, and on hilly in loess plateau with relatively high rainfall and lowevaporation. As a new substitute species for water/soil conservation and rangelandregeneration, it has a big potential to be extended. However, more research on withinwhich scope this species can be extended need to be done

从干旱沙区民勤治沙综合试验站的栽培来看，四翅滨藜在此地表现出了耐旱、耐寒、耐盐碱、耐低温且年生长量大的优良特性，因此可以在有灌溉条件的沙区和降雨较多且蒸发较小的黄土丘陵区进行推广，作为该地区的水土保持和草场更新的新物种，具有一定的推广潜力，但推广地域范围的划分，仍需进一步的试验研究和充分的科学论证。

Genes encoding Drought-Responsive-Element Binding proteins were cloned from Triticum aestivum and Atriplex hortensis. TaDREB1 and AhDREB1 can specifically bind the DRE elements in the promoters and thus activate the transcription of downstream genes in yeast cells as well as transgenic Arabidopsis and transgenic tobacco plants.

克隆了小麦和山菠菜转录因子TaDREB1和AhDREB1基因，它们都编码DRE（Dehydration-Responsive-Element）结合蛋白，在酵母单杂交系统、转基因拟南芥和转基因烟草中都能特异结合DRE元件并激活下游报告基因的表达。

The OsCMO contains 10 exons and 9 introns and encodes a protein with 410 amino acids,which shows 62﹪, 51﹪, 51﹪, 51﹪ and 50﹪ identities in amino acids to CMOs from Arabidopsis thaliana,Atriplex hortensis, Amaranthus tricolor, Suaeda liaotungensis and Beta vulgaris respectively. Semi-quantitative RT-PCR assay revealed OsCMO was significantly up-regulated in the rice seedlings under salt, cold and drought stresses. It suggests that OsCMO might play an important role in rice responses to abiotic stresses.

该基因含有10个外显子和9个内含子，其开放阅读框编码一条长为410个氨基酸残基的多肽，与拟南芥、山菠菜、苋、碱蓬和甜菜等植物的胆碱单加氧酶的氨基酸序列的一致性50﹪～62﹪。mRNA分析表明OsCMO基因在水稻幼苗组织中的表达受高盐、低温和干旱等胁迫的上调诱导表达，表明该基因可能在抵御非生物胁迫中发挥重要作用。

The United Nations says some African farmers grow bambara groundnuts during long dry periods. The seeds of this drought-resistant plant can be boiled for eating or for making flour.

联合国说非洲的一些农民在干燥期间种植落花生，这种抵御干燥环境的植物种子可以煮着吃或者用来做面粉。

The annual seedling such as clove, katsuratree, Japanese pagoda-tree, border privet, amur barberry, golden caryopteris and gloss privet being taken as experimental tree, the content of chlorophyll and proline, the permeability of plasma membrane were measured and compared under continued drought stress.

方法］选用一年生丁香、连翘、国槐、水蜡、红叶小檗、金叶莸、金叶女贞的苗木为试验材料，在土壤持续干旱胁迫下，对其叶绿素含量、质膜相对透性和脯氨酸含量进行测定与比较。

Dignam laid in clay of an apoplexy and after hard drought, please God, rained, a bargeman coming in by water a fifty mile or thereabout with turf saying the seed won't sprout, fields athirst, very sadcoloured and stunk mightily, the quags and tofts too.

迪格纳穆卒于脑溢血。葬于地下。久旱之后，天降喜雨。一名运泥炭约航行五十英里水路之船夫曰："种子无从萌芽，田野涸竭，色极暗淡，恶臭冲天，沼地与小丘亦如是矣。"
