Developmental plasticity of Brachypodium distachyon in response to P deficiency: Modulation by inoculation with phosphate-solubilizing bacteria.

ABSTRACT:

Background

Mineral phosphorus (P) fertilizers must be used wisely in order to preserve rock phosphate, a limited and non-renewable resource. The use of bio-inoculants to improve soil nutrient availability and trigger an efficient plant response to nutrient deficiency is one potential strategy in the attempt to decrease P inputs in agriculture.

Method

An in vitro co-cultivation system was used to study the response of Brachypodium distachyon to contrasted P supplies (soluble and poorly soluble forms of P) and inoculation with P solubilizing bacteria. Brachypodium's responses to P conditions and inoculation with bacteria were studied in terms of developmental plasticity and P use efficiency.

Results

Brachypodium showed plasticity in its biomass allo
