Extensive Copy Number Variation Explains Genome Size Variation in the Unicellular Zygnematophycean Alga, Closterium peracerosum-strigosum-littorale Complex

Y. W. Kawaguchi, Y. Tsuchikane, K. Tanaka, T. Taji, Y. Suzuki, A. Toyoda, M. Ito, Y. Watano, T. Nishiyama, H. Sekimoto, T. Tsuchimatsu

This study identifies genome size variation in the alga Closterium psl. complex as primarily due to copy number variation, with nonrandom distribution of CNV across gene functions.

Massive rhizobial genomic variations associated with partner quality in Lotus-Mesorhizobium symbiosis

M. Bamba, S. Aoki, T. Kajita, H. Setoguchi, Y. Watano, S. Sato, T. Tsuchimatsu

The paper investigates how genetic variations in rhizobial symbionts affect partner quality in Lotus-Mesorhizobium symbiosis, finding that core genome variations, not symbiosis island genes, correlate with plant growth phenotypes.

Patterns of polymorphism at the self-incompatibility locus in 1,083 Arabidopsis thaliana genomes

T. Tsuchimatsu, P. Goubet, S. Gallina, A.-C. Holl, I. Fobis-Loisy, H. Berges, W. Marande, E. Prat, D. Meng, Q. Long, A. Platzer, M. Nordborg, X. Vekemans, V. Castric

The paper analyzes polymorphism at the S-locus in 1,083 Arabidopsis thaliana genomes to understand the historical loss of self-incompatibility, finding multiple independent origins and recombination events during post-glacial colonization.
