摘要

植物毒性土壤盐碱化是一个全球性问题,在大平原北部和加拿大西部,盐分积聚在每年作物覆盖下地下水位较高的海洋沉积土壤表面,尤其是在湿地附近。作物生产可以利用具有耐盐性的作物品种和栽培品种以及管理方法的改变来克服受盐碱影响的土壤。本研究旨在加深我们对向日葵(Helianthus annuus)基因对高盐度土壤耐受性的了解。使用向日葵关联图谱面板进行了全基因组关联研究,该面板在自然发生的盐碱土壤中生长了两年(2016 年和 2017 年,加拿大萨斯喀彻温省印第安黑德附近),并测量了六种表型:开花天数、高度、叶面积、叶片质量、油分百分比和产量。通过对土壤进行网格取样,然后进行克里格法计算,确定了地块的土壤盐度。计算了向日葵表现的三个估计值:(1) 低土壤盐度下(4 dS/m);(3) 可塑性(表型与土壤盐度之间的回归系数)。有 14 个基因位点具有显著性,其中有一个叶面积和叶片质量基因位点共定位。本研究中发现的一些重要基因组区域,在最近使用同一小组进行的温室盐度实验中也具有重要意义。此外,在其他植物物种中也发现了一些潜在于重要 QTL 的候选基因在盐度反应中的作用。这项研究为改良栽培品种和进一步阐明耐盐碱途径的遗传研究确定了等位基因。

Association studies of salinity tolerance in sunflower provide robust breeding and selection strategies under climate change.

Phytotoxic soil salinity is a global problem, and in the northern Great Plains and western Canada, salt accumulates on the surface of marine sediment soils with high water tables under annual crop cover, particularly near wetlands. Crop production can overcome saline-affected soils using crop species and cultivars with salinity tolerance along with changes in management practices. This research seeks to improve our understanding of sunflower (Helianthus annuus) genetic tolerance to high salinity soils. Genome-wide association was conducted using the Sunflower Association Mapping panel grown for two years in naturally occurring saline soils (2016 and 2017, near Indian Head, Saskatchewan, Canada), and six phenotypes were measured: days to bloom, height, leaf area, leaf mass, oil percentage, and yield. Plot level soil salinity was determined by grid sampling of soil followed by kriging. Three estimates of sunflower performance were calculated: (1) under low soil salinity (< 4 dS/m), (2) under high soil salinity (> 4 dS/m), and (3) plasticity (regression coefficient between phenotype and soil salinity). Fourteen loci were significant, with one instance of co-localization between a leaf area and a leaf mass locus. Some genomic regions identified as significant in this study were also significant in a recent greenhouse salinity experiment using the same panel. Also, some candidate genes underlying significant QTL have been identified in other plant species as having a role in salinity response. This research identifies alleles for cultivar improvement and for genetic studies to further elucidate salinity tolerance pathways.

期刊介绍: Theoretical and Applied Genetics publishes original research and review articles in all key areas of modern plant genetics, plant genomics and plant biotechnology. All work needs to have a clear genetic component and significant impact on plant breeding. Theoretical considerations are only accepted in combination with new experimental data and/or if they indicate a relevant application in plant genetics or breeding. Emphasizing the practical, the journal focuses on research into leading crop plants and articles presenting innovative approaches.
