Study of spontaneous mutations in the transmission of poplar chloroplast genomes from mother to offspring.

ABSTRACT:

Background

Chloroplasts have their own genomes, independent from nuclear genomes, that play vital roles in growth, which is a major targeted trait for genetic improvement in Populus. Angiosperm chloroplast genomes are maternally inherited, but the chloroplast' variation pattern of poplar at the single-base level during the transmission from mother to offspring remains unknown.

Results

Here, we constructed high-quality and almost complete chloroplast genomes for three poplar clones, 'NL895' and its parents, 'I69' and 'I45', from the short-read datasets using multi-pass sequencing (15-16 times per clone) and ultra-high coverage (at least 8500× per clone), with the four-step strategy of Simulation-Assembly-Merging-Correction. Each of the three resulting chloroplast assemblies c
