The alterations in the sap-associated microbiota of papaya plants were studied under drought-stress conditions. A major impact was found which revealed the replacement of several bacterial species by others associated with growth-promoting and stress functions. We propose that the changes found in the sap microbiota composition represent an adaptive mechanism which papaya plants utilize to cope water stress. The identified bacterial species could be exploited as potentially microbial biostimulants to enhance the response of plants to drought stress.

番木瓜树液相关微生物群对干旱胁迫的响应

在干旱胁迫条件下，研究了番木瓜植物液相关微生物的变化。发现一个重大影响，揭示了几种细菌被促进生长和胁迫功能相关的细菌替代。我们建议在汁液微生物群组成中发现的变化代表木瓜植物用来应对水分胁迫的适应性机制。鉴定出的细菌物种可以用作潜在的微生物生物刺激剂，以增强植物对干旱胁迫的响应。
