The accumulation of compatible solutes, such as betaines, proline and sugar alcohols, is a widespread response that may protect plants against environmental stress. It is not yet fully understood how these compounds are involved in the stress tolerance of whole plants. Some plants have been genetically engineered to express enzymes that catalyze the synthesis of various compatible solutes. Some interventions have increased the tolerance of some crop plants to abiotic stress. Furthermore, analysis of such transgenic plants has begun to clarify the roles of compatible solutes in stress tolerance.
诸如甜菜碱、脯氨酸和糖醇等相容性溶质的积累是一种广泛存在的反应，可能保护植物免受环境胁迫。目前尚未完全了解这些化合物如何参与整株植物的胁迫耐受性。一些植物已通过基因工程改造来表达催化各种相容性溶质合成的酶。一些干预措施提高了某些作物对非生物胁迫的耐受性。此外，对这类转基因植物的分析已开始阐明相容性溶质在胁迫耐受性中的作用。
