Colocalization was also observed between the berry weight QTL on LG8 and a gene from the CNR family, which regulates cell number and was involved in fruit size changes during the domestication of tomato [ 69].
Both Pima and Upland cotton underwent many phenotypic changes during the domestication process, including reductions in seed dormancy, a shift to a more compact plant architecture, and loss of photoperiod sensitivity (that is, the plant is no longer dependent on changes in day-length to induce flowering).
Much of its genetic architecture and phenotypic construction changed during domestication from wild rice.
The changes that occur during the domestication of crops such as maize and common bean appear to be controlled by relatively few genes.
If the same is true for the Fabaceae, the most efficient approach to understanding the genetic changes that occurred during the domestication of lupin may be to study intensively a better characterized crop such as common bean.
Since DNA changes that have occurred during the domestication process can be considered as a historical record, changes such as functional nucleotide polymorphisms (FNPs) in existing landraces, cultivars, and wild relatives provide strong hints that can be used to establish such a model.
A concordant response is consistent with differences between slow-growing wild and fast-growing domesticated strains being changes that are stable across developmental stages and rearing conditions, and thus may be critical changes that have arisen during the domestication process.
Dnmt3a is an important protein with functions in DNA methylation, and a previous study had shown that Dnmt3a regulates behavioral plasticity to emotional stimuli (LaPlant et al. 2010), indicating that linc-sscg2561 anDnmt3a3a may influence the methylation of genes in the pig nervous system, and thus contribute to changes in emotional behavior during the domestication of the pig.
To identify the genetic variation that caused the seed coat color change during domestication, the W05 genome was compared with the two published bacterial artificial chromosomes of Wm82 that were previously used in I locus studies23,25 (the I locus region is poorly assembled in Wm82_v2), as well as the recently published ZH13 genome5.
This indicates that expression and methylation profiles are relatively stable within breeds, but both may have changed considerably during domestication.
