ABSTRACT
Arsenic (As) is a ubiquitously present carcinogen and its contamination through food is major threat to the large population of the world. The problem is severe in South East Asia including West Bengal India. Thiourea (TU) is a redox active thiol (-SH) based molecule and found positive against variety of stresses, including As stress in lab condition. It can also improve the redox environment of the plant system which is the key component of As toxicity in rice in lab based study. In this work, we, evaluated the impact of TU on selected transporter expression (log2 fold) in developing grains of gosai cultivar of rice. The gosai rice cultivar was selected on the basis of largely consumption pattern in the area, grown in three fields (Control, Experimental field 1 and Experimental field 2) in Nadia district, West Bengal, India. The result indicated impact of TU supplementation on As accumulation pattern in gosai rice grain. Further As concentration was also found to be reduced at grain level by 17.24%. Thus TU can act as sustainable solution to tackle this problem by giving quick response in real field scale. This result could also be useful to understand the mechanism of As reduction in rice in sustainable manner.
