In land plants plastocyanin is indispensable and therefore copper (Cu) availability is a prerequisite for growth. When Cu supply is limited, higher plants prioritize the Cu delivery to plastocyanin by down-regulation of other Cu proteins. Arabidopsis has two plastocyanin genes (PETE1 and PETE2). PETE2 is the predominant isoform in soil-grown plants and in hydroponic cultures it is accumulated in response to Cu addition. It functions as a Cu sink when more Cu is available, in addition to its… CONTINUE READING
