Abstract

Chloroplast genome diversity in taro (Colocasia esculenta) and one other Colocasia species (C. formosana) was previously analysed using concatenated sequences produced by sequencing six polymorphic loci. Here we present complete chloroplast genome sequences for 19 samples (17 new) from six species of Colocasia (Araceae): C. esculenta, C. lihengieae, C. formosana, C. spongifolia, C. oresbia and C. fallax. Three different alignments of these sequences were prepared for a report entitled "Chloroplast capture and range extension after hybridization in taro (Colocasia esculenta)" (Matthews et al. 2024 in press). The alignments show that C. fallax is a distant outgroup and C. oresbia a near outgroup for C. esculenta (including wild and cultivated forms) and a group of closely related wild species (C. lihengiae, C. formosana, C. spongifolia).

The alignments may be useful for future studies involving (1) further populations of each species in the present study, and (2) Colocasia species not represented here.

This work was mainly carried out as part of a project entitled "Mapping Genetic Diversity in Taro to Test Domestication Theories" an international research project supported by the  Japan Society for the Promotion of Science (JSPS Kakenhi No. 17H04614, awarded to P. J. Matthews, with funding for the period 1st April 2017 -– 31st March 2021. Other funding sources for related work carried out before, during and after this period are also noted here.
