干旱是限制植物种植分布、生长发育以及作物产量的主要非生物胁迫因素之一。棉花是重要的经济作物,新疆是中国棉花种植的主要地区,占全国棉花种植面积80%以上。干旱胁迫是影响新疆棉花生产重要的非生物胁迫因素。挖掘关键抗旱基因,揭示棉花对干旱胁迫的应答机制,培育耐逆新材料和新品种,不仅具有重要的科学研究价值,也是服务棉花可持续发展的重要保障。NAC转录因子在植物非生物胁迫信号中起着重要的转录调控作用。然而,...
生长素在植物的正常生长发育中起着至关重要的作用。TAA/YUCCA基因家族编码色氨酸氨基转移酶(tryptophan aminotransferase),是生长素合成的关键酶。然而,棉花中YUCCA(YUC)基因家族尚未见报道。为了揭示YUC基因在棉花中的功能,我们系统地鉴定了五个棉种中的YUC基因家族,包括成员分析、特征描述、基因组内复制和共线关系。转录组学分析表明,GhYUCs参与了棉花的非生...
Songbirds reduce reproduction to help survive drought(图)     Songbirds  reduce reproduction  survive drought       font style='font-size:12px;'> 2020/9/4
With climate change heating the globe, drought more frequently impacts the reproduction and survival of many animal species.New U.S. National Science Foundation-funded research by University...
India being an agrarian nation widely depends upon rainfall for its agricultural productivity. The failure of rainfall and hence shortfall of productivity badly affects national economy. With an intri...

Drought-stricken areas anxiously await the arrival of rain. Full recovery of the ecosystem, however, can extend long past the first rain drops on thirsty ground.According to a study published August 1...
A study led by UC Santa Cruz researchers has found that drought dramatically increases the severity of West Nile virus epidemics in the United States, although populations affected by large outbreaks ...
Cold snaps in sub-tropical ecosystems, life under cities in soils, drought in rainforests, and desertification in grasslands are among the topics featured at the 2016 meeting of the Ecological Society...
By sequencing its genome, scientists are homing in on the genes and genetic pathways that allow the juicy pineapple plant to thrive in water-limited environments. The new findings, reported in the jou...
Background: Calcium-binding proteins that contain EF-hand motifs have been reported to play important roles in transduction of signals associated with biotic and abiotic stresses. To functionally char...
Backg round: MicroRNAs (miRNAs) are small, endogenous RNAs that play important regulatory roles in development and stress response in plants by negatively affecting gene expression post-transcriptiona...
Scientists Reprogram Plants for Drought Tolerance     Scientists  Reprogram Plants  Drought Tolerance       font style='font-size:12px;'> 2015/3/4
Crops and other plants are constantly faced with adverse environmental conditions, such as rising temperatures (2014 was the warmest year on record) and lessening fresh water supplies, which lower yie...
A key question for climate change adaptation is whether existing cropping systems can become less sensitive to climate variations. We use a field-level data set on maize and soybean yields in the cent...
Common bean (Phaseolus vulgaris L.) cultivars (cvs) (Göynük 98, Karacaşehir 90, Şehirali 90, ES 855, and Yunus 90) were subjected to drought stress in order to assess the levels of dro...
Drought stress is considered a restricting factor for plant products; therefore many compounds were applied to minimise the harmful effects of stress. One type of these compounds that have antioxidati...
