The invention relates to genetic loci associated with response to abiotic stress. Compositions and methods useful in identifying and counter-selecting maize plants with having enhanced yield-related traits relative to control plants under abiotic stress conditions such as salt stress and/or drought are provided herein. The methods use molecular genetic markers to identify, select and/or constructsalt stress tolerant and/or drought tolerant maize plants. Also provided are methods to enhance tolerance to salt stress and/or drought in crop plants by transforming crop plants with the Zea mays antiporter/sodiunn ion transporter or by introducing favorable allelic variants of the Zea mays antiporter/sodiunn ion transporter gene via gene editing. 本发明涉及与对非生物胁迫的响应相关联的基因座。本文提供了可用于鉴定和反选择玉米植物的组合物和方法，所述玉米植物在非生物胁迫条件诸如盐胁迫和/或干旱下相对于对照植物具有增强的收率相关的性状。所述方法使用分子遗传标记来鉴定、选择和/或构建盐胁迫耐受性和/或耐旱性玉米植物。还提供了通过利用玉米反向转运蛋白/钠离子转运蛋白转化作物植物或者通过经由基因编辑引入玉米反向转运蛋白/钠离子转运蛋白基因的有利等位变体来增强作物植物对盐胁迫和/或干旱的耐受性的方法。
