Selenium and its Role in Higher Plants | SpringerLink

Abstract. Selenium (Se) is a naturally occurring metalloid element which occurs nearly in all environments in the universe. The common sources of Se in earth crust occurs in association with sulfide minerals as metal selenide whereas, it is rarely seen in elemental form (Se 0).Furthermore, Se is considered a finite and non-renewable resource on earth, and has been found to be an essential ...
