The Relationship

Meiotic recombination frequency varies along chromosomes and strongly correlates with sequence divergence. However, the causality underlying this correlation is unclear. To untangle the relationship between recombination landscapes and polymorphisms, we characterized the genome-wide recombination landscape in the absence of polymorphisms, using Arabidopsis thaliana homozygous inbred lines in which a few hundred genetic markers were introduced through mutagenesis. We found that megabase-scale recombination landscapes in inbred lines are strikingly similar to the recombination landscapes in hybrids, with the sole exception of heterozygous large rearrangements where recombination is prevented locally. In addition, we found that the megabase-scale recombination landscape can be accurately predicted by chromatin features. Our results show that polymorphisms are not causal for the shape of the megabase-scale recombination landscape, rather, favor alternative models in which recombination and chromatin shape sequence divergence across the genome.

Abstract(+)-7-iso-Jasmonoyl-l-isoleucine (JA-Ile) is a lipid-derived phytohormone implicated in plant development, reproduction, and defense in response to pathogens and herbivorous insects. All these effects are instigated by the perception of JA-Ile by the COI1-JAZ co-receptor in the plant body, which in Arabidopsis thaliana is profoundly influenced by the short JAZ degron sequence (V/L)P(Q/I)AR(R/K) of the JAZ protein. Here, we report that SlJAZ-SlCOI1, the COI1-JAZ co-receptor found in the tomato plant, relies on the extended JAZ degron sequence (V/L)P(Q/I)AR(R/K)XSLX instead of the canonical JAZ degron. This finding illuminates our understanding of the mechanism of ligand perception by JA-Ile in this plant, and will inform both efforts to improve it by genetic modification of the SlCOI1-SlJAZ co-receptor, and the development of the synthetic agonists/antagonists.
