genetic improvement of legume roots for adaption to acid soils

The Crop Journal 2023年第4期11卷 1022-1033页

作者： Xinxin Li Xinghua Zhang Qingsong Zhao Hong Liao Root Biology Center College of Resources and EnvironmentFujian Agriculture and Forestry UniversityFuzhou 350002FujianChina

Acid soils occupy approximately 50% of potentially arable lands.Improving crop productivity in acid soils,therefore,will be crucial for ensuring food security and agricultural sustainability.High soil acidity often coexists with phosphorus(P) deficiency and aluminum(Al) toxicity,a combination that severely impedes crop growth and yield across wide areas.As roots explore soil for the nutrients and water required for plant growth and development,they also sense and respond to below-ground stresses.Within the terrestrial context of widespread P deficiency and Al toxicity pressures,plants,particularly roots,have evolved a variety of mechanisms for adapting to these stresses.As legumes,soybean(Glycine max) plants may acquire nitrogen(N) through symbiotic nitrogen fixation(SNF),an adaptation that can be useful for mitigating excessive N fertilizer use,either directly as leguminous crop participants in rotation and intercropping systems,or secondarily as green manure cover crops.In this review,we investigate legumes,especially soybean,for recent advances in our understanding of root-based mechanisms linked with root architecture modification,exudation and symbiosis,together with associated genetic and molecular strategies in adaptation to individual and/or interacting P and Al conditions in acid soils.We propose that breeding legume cultivars with superior nutrient efficiency and/or Al tolerance traits through genetic selection might become a potentially powerful strategy for producing crop varieties capable of maintaining or improving yields in more stressful soil conditions subjected to increasingly challenging environmental conditions.

Juglans mandshurica is an economically and ecologically valuable species that is used for various construction purposes,making luxurious furniture,as food and sources of medicinal substances and landscaping because of its excellent wood,edible fruits and rich in various types of chemical compounds.In the past few decades,several genetic improvements of J.mandshurica were made,with a focus on the selection of improved varieties and on breeding technology.Many elite provenances and families were selected based on growth traits or wood properties.In recent years,with the increasing demand for high-quality seedlings in Chinese forestry production,the breeding goals of genetic improvement for J.mandshurica were redefined to include other traits,such as fruit yield and contents of medicinal component.However,the improvement processes were still slow due to the long breeding cycle and the limited use of advanced breeding technologies,resulting in the selection of fewer improved varieties.In this review,we summarized the research progresses on genetic improvements of J.mandshurica and other related works,and discussed research gaps and suggested future directions for genetic improvement of the species.The review provides valuable insight for the selection of improved varieties and production of excellent germplasms.

Journal of Integrative Plant Biology 2023年第2期65卷 496-525页

作者： Zhirui Yang Feng Qin State Key Laboratory of Plant Environmental Resilience College of Biological SciencesChina Agricultural UniversityBeijing 100193China

With ongoing global climate change,water scarcity-induced drought stress remains a major threat to agricultural productivity.Plants undergo a series of physiological and morphological changes to cope with drought stress,including stomatal closure to reduce transpiration and changes in root architecture to optimize water uptake.Combined phenotypic and multi-omics studies have recently identified a number of drought-related genetic resources in different crop species.The functional dissection of these genes using molecular techniques has enriched our understanding of drought responses in crops and has provided genetic targets for enhancing resistance to drought.Here,we review recent advances in the cloning and functional analysis of drought resistance genes and the development of technologies to mitigate the threat of drought to crop production.

Wheat(Triticum aestivum)is a staple food for about 40%of the world’s population.As the global population has grown and living standards improved,high yield and improved nutritional quality have become the main targets for wheat breeding.However,wheat production has been compromised by global warming through the more frequent occurrence of extreme temperature events,which have increased water scarcity,aggravated soil salinization,caused plants to be more vulnerable to diseases,and directly reduced plant fertility and suppressed yield.One promising option to address these challenges is the genetic improvement of wheat for enhanced resistance to environmental stress.Several decades of progress in genomics and genetic engineering has tremendously advanced our understanding of the molecular and genetic mechanisms underlying abiotic and biotic stress responses in wheat.These advances have heralded what might be considered a“golden age”of functional genomics for the genetic improvement of wheat.Here,we summarize the current knowledge on the molecular and genetic basis of wheat resistance to abiotic and biotic stresses,including the QTLs/genes involved,their functional and regulatory mechanisms,and strategies for genetic modification of wheat for improved stress resistance.In addition,we also provide perspectives on some key challenges that need to be addressed.

Sperm is essential for successful artificial insemination in dairy cattle,and its quality can be influenced by both epi-genetic modification and epigenetic inheritance.The bovine germline differentiation is characterized by epigenetic reprogramming,while intergenerational and transgenerational epigenetic inheritance can influence the offspring’s development through the transmission of epigenetic features to the offspring via the germline.Therefore,the selec-tion of bulls with superior sperm quality for the production and fertility traits requires a better understanding of the epigenetic mechanism and more accurate identifications of epigenetic biomarkers.We have comprehensively reviewed the current progress in the studies of bovine sperm epigenome in terms of both resources and biological discovery in order to provide perspectives on how to harness this valuable information for genetic improvement in the cattle breeding industry.

Abiotic stresses, predominately drought, heat, salinity, cold, and waterlogging, adversely affect cereal crops. They limit barley production worldwide and cause huge economic losses. In barley, functional genes under various stresses have been identified over the years and genetic improvement to stress tolerance has taken a new turn with the introduction of modern geneediting platforms. In particular, clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein 9(Cas9) is a robust and versatile tool for precise mutation creation and trait improvement. In this review, we highlight the stress-affected regions and the corresponding economic losses among the main barley producers. We collate about 150 key genes associated with stress tolerance and combine them into a single physical map for potential breeding practices. We also overview the applications of precise base editing, prime editing, and multiplexing technologies for targeted trait modification, and discuss current challenges including high-throughput mutant genotyping and genotype dependency in genetic transformation to promote commercial breeding. The listed genes counteract key stresses such as drought, salinity, and nutrient deficiency, and the potential application of the respective gene-editing technologies will provide insight into barley improvement for climate resilience.

Japonica rice variety Kanto 194 as the donor of resistance gene Stv-b^i and Iow-amylose content gene Wx-mq was used to improve the resistance and eating quality of Wuyujing 3 by the breeding strategy of backcross. In continuous backcross and selfcross generations, the related molecular markers with Stvobi and Wx-mq genes were utilized for genotypic detection by associated with resistance identification of rice stripe disease and agronomic traits selection. Finally, 10 improved lines with homozygous genotype Stv-b^i Stv-b^iWx-mqWx-mq were obtained from BC3F4 generation. The results of comparative analysis indicated that most characters of these lines were consistent with those of recipient parent Wuyujing 3, except for the improved resistance, appearance and eating quality. By evaluation of the comprehensive performance of them, two excellent lines K01 and K04 were selected for further experiments.
