Self-alleviation of continuous-cropping obstacles in potato via root-exudate-driven recruitment of growth-promoting bacteria.

ABSTRACT: Continuous-cropping (CC) obstacles are among the primary factors limiting the development of global agriculture. Although most plants are negatively affected by barriers that develop with CC, they may also overcome such obstacles by altering the soil biological and chemical environment to favor plant growth. In this study, we investigated the mechanism by which plants recruit beneficial microorganisms using root exudates to alleviate obstacles in a 10-year CC potato system. On day 20 after potato emergence, soil microorganisms in the CC system promoted an increase in adventitious root (AR) numbers by increasing the indole-3-acetic acid (IAA) content of the rhizosphere soil. Analysis of rhizosphere bacterial communities using 16S rRNA sequencing revealed that CC alters community structure,
