Expression profile of contrasting maize genotypes grown on acid and control soil (root tips)


ABSTRACT: Aluminum toxicity is one of the major limiting factors for many crops worldwide. The primary symptom of Al toxicity syndrome is the inhibition of root growth, leading to poor water and nutrient absorption. The causes of this inhibition are still elusive, with several biochemical pathways being affected and with a significant variation between species. Most of the work done so far to investigate the genes responsible for Al tolerance used hydroponic culture. Here we evaluated plant responses using soil as substrate, which is a condition closer to the field reality. We used Affymetrix chips to reveal the transcriptional changes of two maize genotypes contrasting for Al tolerance.
