In this literature review, we discuss the various functions of beneficial plant bacteria in improving plant nutrition, the defense against biotic and abiotic stress, and hormonal regulation. We also review the recent research on rhizophagy, a nutrient scavenging mechanism in which bacteria enter and exit root cells on a cyclical basis. These concepts are covered in the contexts of soil agriculture and controlled environment agriculture, and they are also used in vertical farming systems. Vertical farming-its advantages and disadvantages over soil agriculture, and the various climatic factors in controlled environment agriculture-is also discussed in relation to plant-bacterial relationships. The different factors under grower control, such as choice of substrate, oxygenation rates, temperature, light, and CO supplementation, may influence plant-bacterial interactions in unintended ways. Understanding the specific effects of these environmental factors may inform the best cultural practices and further elucidate the mechanisms by which beneficial bacteria promote plant growth.
在本综述中，我们讨论了有益植物细菌在改善植物营养、抵御生物和非生物胁迫以及激素调节方面的各种功能。我们还回顾了最近关于根际吞噬作用的研究，这是一种营养 scavenging 机制，细菌在其中周期性地进出根细胞。这些概念在土壤农业和可控环境农业的背景下进行了阐述，并且它们也被用于垂直种植系统。还讨论了垂直种植与土壤农业相比的优缺点，以及可控环境农业中的各种气候因素与植物 - 细菌关系的联系。种植者可控的不同因素，如基质选择、充氧率、温度、光照和二氧化碳补充，可能会以意想不到的方式影响植物 - 细菌相互作用。了解这些环境因素的具体影响可能有助于确定最佳栽培实践，并进一步阐明有益细菌促进植物生长的机制。
