The significance of methionine, histidine and tryptophan in plant responses and adaptation to cadmium stress

Popis výsledku v původním jazyce

Noccaea caerulescens (NC) and Arabidopsis halleri (AH) were studied to compare Cd accumulation and resistance. After 30, 60 and 90 days of plant cultivation in Cd contaminated soil amino acids were determined in plants. The comparison between both species showed that Cd stress resulted in different changes of amino acids levels playing significant role in plant adaptation to Cd stress. Our analyses indicated the higher accumulations of amino acids in the roots of NC compared to AC. Contrasting responsesof plants to Cd contamination were confirmed in methionine metabolism. Methionine was determined only in roots of AH and it decreased with increasing Cd contamination. NC contains more than 10-fold higher content of histidine than AC. This amino acid may be involved in Cd resistance and accumulation by reducing oxidative damage. Tryptophan plays a major role in the regulation of plant development and in defence responses. Its increase for NC treatments in contrast to AH treatments was d
