Data from: Topological DNA-binding of SMC-like RecN promotes RecA-mediated DNA double-strand break repair

Kenji Keyamura & Takashi Hishida
Bacterial RecN, closely related to the structural maintenance of chromosomes (SMC) family of proteins, functions in the repair of DNA double-strand breaks (DSBs) by homologous recombination. However, the understanding of how RecN acts in concert with the RecA recombinase to promote DSB repair remains limited. Here, we demonstrated that the purified Escherichia coli RecN protein topologically loads onto both single-stranded DNA (ssDNA) and double-stranded DNA (dsDNA) that has a preference for ssDNA. RecN topologically bound...

Data from: Phenotypic determinism and contingency in the evolution of hypothetical tree-like organisms

Tomonobu Nonoyama & Satoshi Chiba
Whether evolutionary history is mostly contingent or deterministic has been given much focus in the field of evolutionary biology. Studies addressing this issue have been conducted theoretically, based on models, and experimentally, based on microcosms. It has been argued that the shape of the adaptive landscape and mutation rate are major determinants of replicated phenotypic evolution. In the present study, to incorporate the effects of phenotypic plasticity, we constructed a model using tree-like organisms. In...

Variations in leaf economics spectrum traits for an evergreen coniferous species: Tree size dominates over environment factors

Zhili Liu, Kouki Hikosaka, Fengri Li & Guangze Jin
Many leaf traits strongly vary with tree size and environmental factors, but the importance of these factors to intraspecific variations of leaf traits in forest trees have rarely been simultaneously evaluated. We measured needle longevity and specific leaf area (SLA) and nitrogen (N) content of every needle age (0 to 4 year old) for 65 individuals with 0.3-100 cm diameter at breast height (DBH) for an evergreen coniferous species, Pinus koraiensis Sieb. et Zucc., in...
