The present work investigated the roles of Si and/or Rhizophagus irregularis on growth, nutrient acquisition, proline biosynthesis and productivity of two pigeonpea genotypes (metal tolerant—PUSA 2002, metal sensitive—PUSA 991) under Cd (25, 50 mg kg⁻¹), Zn (600, 1000 mg kg⁻¹) stress. The key mechanisms evoked include reducing active heavy metal ions in growth media, reduced metal uptake and root-to-shoot translocation, chelation and stimulation of antioxidant systems in plants, complexation and co-precipitation of toxic metals with Si in different plant parts, compartmentation and structural alterations in plants and regulation of the expression of metal transport genes. ions and with other environmental factors.

Presently, many countries are focusing special attention towards soilless cultivation i.e., hydroponics, aeroponics and other substrates medium like cocopeat, compost etc. in mining industries, foundries, smelters, coal-burning power plants and agriculture. Heavy metal buildup in soils is of concern in agricultural production due to the adverse effects on food safety and marketability, crop growth due to phytotoxicity, and environmental health of soil organisms. Most of the cellular and molecular. metals, including copper, manganese, iron, cobalt, zinc, and chromium, are, however, essential to plant metabolism in trace quantities.

Pollution of the environment with the toxic heavy metals has become one, of the major causes for worry for human health in both emerging and, advanced countries. Plant responses to heavy metals are molecularly regulated in a process called metal homeostasis, which also includes regulation of the metal-induced reactive oxygen species (ROS) signaling pathway. Reports, are also available on the occurrence of high con-, centration of these metals in crop plants, and on. Plants are stationary, and roots, of a plant are the primary contact site for heavy, metal ions in soil. Lewis S, Donkin ME, Depledge MH (2001) Hsp, 70 expression in Enteromorpha intestinalis.
