Retrotransposon molecular markers resolve cocoyam (Xanthosoma sagittifolium) and taro (Colocasia esculenta) by type and variety.

The most important worldwide root and tuber crops are cassava (Manihot esculenta), sweet potato (Ipomoea batatas), potato (Solanum tuberosum), yam (Dioscorea spp.), malanga (Colocasia esculenta), and tannia (Xanthosoma spp.).

(93) For example, Yeh and coworkers have casted and cured polydimethylsiloxane onto superhydrophobic Xanthosoma sagittifolium leaves and transferred the micropapillary structures to produce a series of superhydrophobic polymer-based coatings on mild steels (Fig.
