Interdependence of Nitrogen Nutrition and Photosynthesis in Pisum sativum L: I. Effect of Combined Nitrogen on Symbiotic Nitrogen Fixation and Photosynthesis.

abstract：:We used pulsed-field gel electrophoresis and restriction fragment mapping to analyze the structure of Medicago truncatula chloroplast DNA (cpDNA). We find most cpDNA in genome-sized linear molecules, head-to-tail genomic concatemers, and complex branched forms with ends at defined sites rather than at random sites as ...
