Question

Nodulin and nodulation genes are coded by the genomes of

Answer 1

HEY FRND...☺☛⚫✔⛤
⬛⚫☛✔Two classes of genes are being analyzed: mutants that produce phenotypic changes in nodule number or physiology (referred to as symmutants) and genes encoding nodulins or other proteins with important roles in nodule biochemistry. Our approach has been to carefully characterize the symmutants, thereby defining as accurately as possible their role in nodule formation and to map each of the sym and nodulin genes on the pea linkage map. Functionally related genes do not generally form clusters in the genomes of higher eukaryotes, and we expected the genes involved in nodule formation to be widely distributed on the pea linkage map. ⬛⚫☛✔Correspondance between the map positions of sym and nodulin genes might indicate that the two are genetically related. If the two are coded by the same locus the precise metabolic defect affecting nodule formation in the mutant and, conversely, the mechanism through which a nodulin influences nodulation would be revealed.⛤⛤⛤⛤⛤⛤⛤⛤⛤⛤⛤⛤⛤
