The research direction


   The State Key Laboratory of Crop Stress Biology for Arid Areas focuses oin the major sicientific needs forof promoting the scientific development of arid agriculture and conductdoes research for developing theoriesetical reserve and applied practicespractical exploration to based on solveing the major scientific and technical issues of arid agriculture includingto protection of both arid food security and ecological security in the arid areas. The main research directions are the as followings:

Direction one: Exploration of crop stress-resistant germplasm and genetic resources
   This direction includes three research areas: (1) selection and identification of stress-resistant crop germplasm, (2) studying the genetic basis of resistance to various biotic and abiotic stresses, and (3) preserve germplasm and genetic resources. The plant germplasm including Selecting grain, fruit, vegetables and other crops and their related speciesplant germplasms of arid areas as main research objects, are collected, preserved, cataloged, tidy and evaluated comprehensively for their resistance to germplasms depending on traits of drought, salinity, low temperatures, disease and insect resistance., cold resistance and high yield and quality comprehensively; Facilities are established and technologies are developed and used for selecting, evaluating and improving germplasm for resistance to various biotic and abiotic stressessetting up the technical system of election and evaluation of germplasm resources on stress resistance;select germplasm resources of great importance in genetic improvement of crop on stress resistance and high yield and quality. Indicate the Ggenetic basis and molecular mechanisms of resistance to various biotic and abiotic stresses regularity of many important characters including drought, salinity, cold, disease and insect resistance, and high yield and quality are studied to provide scientific basis for developing and set up the foundation of crop sStress biology and breeding for new germplasm and cultivars research and resistance germplasm innovation and new varieties breeding. This direction includes three parts: (1) selection and identification of crop resistance germplasm (2) studying the genetic regularity of characteristics of resistance (3) conservation of germplasm and genetic resources.

Dierection two: Mechanisms of cCrop responses mechanism to abiotic stress.
   This direction includes two parts: 1) basic research of abiotic stresses of arid crops and 2) development of strategies and technologies for developing new germplasm and cultivars with resistance to abiotic stresses. Selecting the Aabiotic stresses of arid crops including drought, salinity, low temperature and high temperature are theas majorin research areas for this direction.objects, study the Ccrop adaptation and resistance mechanisms of resistance to these abiotic stresses are studied in depth with selected the resistant and susceptible lines of crops including (wheat, corn, fruit trees, and vegetables, etc.) as main germplasm materials on Research approaches include morphology, physiology and biochemistry, cell biology, genetics and epigenetics, molecular biology to determinerevealing the damage mechanisms of the abiotic stresses toon crops. Studies include and clarifying crop acquiring, resisting and withstanding adversity signal transduction pathways and gene regulatory networks, and develop exploring resistance strategies and techniques for utilizing resistance to abiotic stresses in crops. The goal of research in this direction is to ,provide a theoretical basis forabout improving crop resistance to abiotic stress resistance through breeding for new germplasm and cultivars.

Direction three: Mechanisms of the interactions mechanism between crops and harmful organisms.

   This direction includes four parts: 1) epidemiology of of major crop diseases and pests, 2) mechanisms of virulence in harmful organisms, 3) characteristics and mechanisms of crops resistance to harmful organisms, and (4) strategies and technologies for effective management of major crop pests and diseases. Directing at The following major harmful diseases and pests oforganisms on arid crops in arid areas are studied:, many harmful organisms of grain, fruit, vegetables, such as wheat stripe rust, wheat scab, viralus diseases of wheat, wheat midge, wheat aphid of wheat;, apple cankerrot;, and Phytophthoraeggs bacterial diseases as the main object, are studied usingfrom the molecular and, cellular approaches at, individual and population biology levels in order to reveal the epidemiologicaloccurrence patterns and interaction mechanisms of the interactions between crops and harmful organisms, especially and crops, further indicate the genetic basis of the interactions and the virulence mechanisms of virulence in of crop pathogens diseases and insect pests, crop resistance, mechanism to diseases and insect pests, the genetic basis of interaction between harmful organisms and crop and the roles of environmental factors on harmful organisms populations. Theis studies in this directiony willcan also provide a scientific basis and key technologies for breeding crops with resistance to diseases and insects and resistance breeding, and develop strategies for integrated disease and pest managementestablishment of preventing and controlling of major pests and diseases on food and fruit crops of the arid areas and construction of integrated pest governance system.

Direction four: Develop new stress-resistant ggermplasm and cultivars innovation of resistant crop to stress and variety excogitation

   This direction includes (1) theory and methods for developing stress-resistant cultivars of crops for arid areas and (2) developing new germplasm and cultivars with high yield, high quality, resistance to biotic and abiotic stresses, and wide adaptation to various arid areas. Based on available knowledge and new findings from studies for directions 1-3 on resistance to biotic and abiotic stresses According to some important traits including drought, salinity, cold resistance and disease resistance (such as wheat stripe rust, powdery mildew, wheat scab, wheat aphids of wheat, grape powdery mildew of grapes, apple ring rot and canker of apple, and soft rot of cabbage), establish the new theories will be established and new effective methods will be developed for developing new germplasm and cultivars of the majorabout crops grown in arid areas includingresistance germplasm and new varieties excogitation of wheat, corn, canola, special cropsminor coarse cereals, apples, grapes, and vegetables usingand create new resistance germplasm through the modern biotechnology such as cell engineering, chromosome engineering, genetic engineering, molecular marker-assisted selection technology combining with conventional breeding technologies. GrowingCultivate the new stress-resistantce cultivars with high yield, high quality and wide adaption tovarieties which suitable for various arid areas agricultural production under optimized production systems and practices should sustainably improve agricultural production in the large arid areas in China while improving the environment, conserving natural resources, increasing farmer's income, and reducing costs and improving food quality and safety for consumersand large-scale production applications.
