Immunocytological Analysis of Meiotic Recombination in the Gray Goose (<b><i>Anser anser</i></b>)

Abstract: Studies on mammals demonstrate wide interspecific variation in the number and distribution of recombination events along chromosomes. Birds represent an interesting model group for comparative analysis of cytological and ecological drivers of recombination rate evolution. Yet, data on variation in recombination rates in birds are limited to a dozen of species. In this study, we used immunolocalization of MLH1, a mismatch repair protein marking mature recombination nodules, to estimate the overall recombination… Show more

“…This indicates that GRC is likely to be an indispensable component of the songbird germline genome (including the rook, the infraorder Corvides). We found no indications of GRC in eight species beyond this Suborder reanalyzing our own data 6,7 and published SC images [8][9][10][11] (Fig. 1).…”

“…There is a regular presence of three or more MLH1 foci on the largest macrobivalents in the Greater rhea ( Table 1 ). Similar observations were reported in four species of Galloanserae and also in pigeons, with species-specific distributions of foci along chromosomal arms [ 45 , 48 ]. This occurrence of multiple CO events per macrobivalent, however, is not shared by all birds.…”

“…This suggests that the GRC is an important component of the germline genome. However, no GRCs were observed [by reanalyzing our own data (14,15) and published SC images (16)(17)(18)(19)] in eight species of nonpasserine birds from seven separate lineages (Fig. 1).…”
