Tomato ethylene sensitivity determines interaction with plant growth-promoting bacteria.

ABSTRACT:

Background and aims

Plant growth-promoting bacteria (PGPB) are soil micro-organisms able to interact with plants and stimulate their growth, positively affecting plant physiology and development. Although ethylene plays a key role in plant growth, little is known about the involvement of ethylene sensitivity in bacterial inoculation effects on plant physiology. Thus, the present study was pursued to establish whether ethylene perception is critical for plant-bacteria interaction and growth induction by two different PGPB strains, and to assess the physiological effects of these strains in juvenile and mature tomato ( Solanum lycopersicum ) plants.

Methods

An experiment was performed with the ethylene-insensitive tomato never ripe and its isogenic wild-type line in which thes
