Transcription profiling of Arabidosis Ler and Cvi ecotypes and 17 derived inbred recombinant lines subjected to micro-landscape fragmentation and two levels of disturbance revealing functional landscape genomics reveals genetic changes in fixed and migrating experimental populations.

ABSTRACT: We carried out a five-generation selection experiment in which two Arabidopsis accessions (Ler and Cvi) and 17 Recombinant Inbred Lines (RILs) derived from them were subjected in 24 replicated populations to four levels of micro-landscape fragmentation and two levels of disturbance, factorially crossed with each other to yield 8 experimental selection regimes. We used 19 lines (including the two parental Ler and Cvi) in generation 1 of our experiment, nine of which contained the erecta mutation and ten of which did not. Lines expressing the erecta mutation are short and compact and are likely to disperse seeds over shorter distances. Both the non-erecta and the erecta lines spanned the full available range of seed sizes from the original 162 RILs in the collection. We set up 24 experiment
