TL;DR: LtMADS2, when expressed in transgenic Arabidopsis plants under the control of the AP1 promoter, could partially complement the organ number defect of the severe ap1-15 mutant allele, confirming a close relationship between LtM ADS2 and AP1.

TL;DR: Detailed methylome analyses in a geographically dispersed A. thaliana population, which constitutes a collection of near-isogenic lines, diverged for at least a century from a common ancestor, show that genome-wide epigenetic variation accumulates mostly in a clock-like manner, and epigenetic divergence thus parallels the pattern of genome- wide DNA sequence divergence.

TL;DR: A model in which pattern forming genes act early to determine the salivary gland anlage by regulating the expression of salivARY gland determining genes, which in turn control genes that are involved in salivaries gland morphogenesis is proposed.

TL;DR: The two new AI-RIL populations derived from crosses of Columbia to Estland and Kendallville provide an excellent resource for high precision QTL mapping and are used to map QTL for light response and flowering time, and to identify segregation distortion in one of the AI- RIL populations due to a negative epistatic interaction between two genomic regions.

TL;DR: Following an experimentally determined recombination landscape of Arabidopsis and next generation sequencing-specific biases, more than 400,000 mapping-by-sequencing experiments are simulated, informing about the properties of different crossing scenarios, the number of recombinants and sequencing depth needed for successful mapping experiments.
