Widespread production of plant growth-promoting hormones among marine bacteria and their impacts on the growth of a marine diatom.

ABSTRACT:

Background

Reciprocal exchanges of metabolites between phytoplankton and bacteria influence the fitness of these microorganisms which ultimately shapes the productivity of marine ecosystems. Recent evidence suggests that plant growth-promoting hormones may be key metabolites within mutualistic phytoplankton-bacteria partnerships, but very little is known about the diversity of plant growth-promoting hormones produced by marine bacteria and their specific effects on phytoplankton growth. Here, we aimed to investigate the capacity of marine bacteria to produce 7 plant growth-promoting hormones and the effects of these hormones on Actinocyclus sp. growth.

Results

We examined the plant growth-promoting hormone synthesis capabilities of 14 bacterial strains that enhance the growt
