Inoculation with Efficient Nitrogen Fixing and Indoleacetic Acid Producing Bacterial Microsymbiont Enhance Tolerance of the Model Legume to Iron Deficiency.

The aim of this study was to assess the effect of symbiotic bacteria inoculation on the response of genotypes to iron deficiency. The present work was conducted on three genotypes: A17, TN8.20, and TN1.

Effect of salt on physiological responses of barley to iron deficiency.

Iron chlorosis is very common on alkaline soils such as calcareous ones, since iron availability is limited by high pH. Under these conditions of iron deficiency, graminaceous plant species induce special mechanisms for iron acquisition, involving enhanced release of iron chelators called phytosiderophores. On the other hand, it is known that most of salt soils have alkaline pH.
