HetR may be the expert regulator of heterocyst differentiation in sp. nitrogen fixation (34). sp. strain PCC 7120 (here referred to as 7120) often used in the study of heterocyst differentiation responds to nitrogen step-down by generating semiregularly spaced heterocysts along its filaments. Heterocyst pattern formation may be mainly interpreted by an activator-inhibitor magic size… Continue reading HetR may be the expert regulator of heterocyst differentiation in sp.
