This review updates the present status of the field of molecular markers and marker-assisted selection(MAs),using the example of drought tolerance in *** accuracy of selected quantitative trait loci(QTLs),candidate genes and suggested markers was assessed in the barley genome *** common strategies are described for molecular marker development,candidate gene identification and verification,and their possible applications in MAs to improve the grain yield and yield components in barley under drought *** strategies are based on the following five principles:(1)Molecular markers are designated as genomic‘tags’,and their‘prediction’is strongly dependent on their distance from a candidate gene on genetic or physical maps;(2)plants react differently under favourable and stressful conditions or depending on their stage of development;(3)each candidate gene must be verified by confirming its expression in the relevant conditions,e.g.,drought;(4)the molecular marker identified must be validated for MAs for tolerance to drought stress and improved grain yield;and(5)the small number of molecular markers realized for MAs in breeding,from among the many studies targeting candidate genes,can be explained by the complex nature of drought stress,and multiple stress-responsive genes in each barley genotype that are expressed differentially depending on many other factors.

种群是草原生态系统结构、功能形成和发展的基础。然而,长期放牧伴随着全球气候变化深刻影响着种群的生长和繁殖。长芒草(stipa bungeana)是黄土高原典型草原的优势种,具有较高的生态和经济价值。该研究依托黄土高原典型草原长期滩羊轮牧实验平台,采用完全随机的裂区实验设计,以放牧率(0、2.7、5.3、8.7 sheep·hm^(-2))作为主因子,氮添加水平(0、5、10、20 g·m^(-2))作为副因子,探究放牧、氮添加及其交互作用对长芒草的形态性状、地上生物量及其占群落生物量比例的作用。结果表明:随放牧率的增加,长芒草的株高、冠幅直径、分蘖密度、实生苗密度、地上生物量和生物量占比呈“单峰”曲线变化趋势,种群密度降低。而氮添加增加长芒草的株高、冠幅直径、生殖枝密度、分蘖密度、地上生物量和生物量占比;实生苗密度随氮添加的增加呈先增后减的趋势。相比氮添加,放牧对长芒草地上生物量和生物量占比的总效应小,放牧对地上生物量有直接的负效应,并通过调控分蘖密度、种群密度及地上生物量影响其生物量占比;氮添加不仅对地上生物量有直接的积极效应,还通过株高、生殖枝密度对地上生物量有间接的正效应,同时通过调控种群密度、冠幅直径、分蘖密度和生殖枝密度影响生物量占比。总体上,氮添加增加长芒草的冠幅直径和生殖枝密度(相比株高和分蘖密度),放牧增加实生苗密度(相比种群密度),而放牧和氮添加的交互作用显著影响生殖枝密度。放牧率为4.10和5.29 sheep·hm^(-2)时长芒草具有最大地上生物量及其群落占比。上述结果表明放牧和氮添加通过影响长芒草种群的形态特征来调控其地上生物量和群落地位。

作者： Akniyazov Таmerlan the sino-kazakh Economic and Trade Institute at the Universit of International Business and Economics

My ‘Journey to the East’I was born in sakhalin Island and grew up in the Zhetysu region in the southeast of kazakhstan. After graduating from high school in 2007, I enrolled in a local university in kazakhstan, intending to major in physics. However, one summer evening, my father came home from work with an enrollment brochure from China’s Tongji university in his hand. He approached me and asked,“Do you want to study abroad?” Longing for independence at an early age and eager to explore the outside world, I agreed without hesitation. Not long after, I was sitting on the train bound for shanghai, China, starting my “Journey to the East.”
