Oca (Oxalis tuberosa)

The name is derived from the Quechua words ok’aocca and/or uqa. Tubers are mainly claviform and cylinder in shape and tuber color ranges from white to deep grayish purple. Oca yields up to 20-40 tons per ha and tubers are ready for harvesting 7 months after planting. Oca is also grown in Mexico and New Zealand where oca has become a popular table vegetable and is simply called yam or New Zealand yam. Oca is a good source of carbohydrate, antioxidant compounds (anthocyanin and flavonoids), potassium and oxalates.

Cryopreserved potato shoot tips showed genotype-specific response to sucrose concentration in rewarming solution (RS)

Cryopreservation protocols have been successfully developed for hundreds of species and thousands of genotypes in laboratories around the world. In many of the protocols, the rewarming process occurs in a rewarming solution (RS) with a high concentration of sucrose (0.8–1.2 M).

A taxonomic monograph of Ipomoea integrated across phylogenetic scales

Taxonomic monographs have the potential to make a unique contribution to the understanding of global biodiversity. However, such studies, now rare, are often considered too daunting to undertake within a realistic time frame, especially as the world’s collections have doubled in size in recent times.

Structural genome analysis in cultivated potato taxa

The common potato (Solanum tuberosum L.) is an important staple crop with a highly heterozygous and complex tetraploid genome. The other taxa of cultivated potato contain varying ploidy levels (2X–5X), and structural variations are common in the genomes of these species, likely contributing to the diversification or agronomic traits during domestication

Conserving Biodiversity for the Future

Food production will be hard pressed to keep up with demand in the next 30 years. The world’s population is expected to swell by some two billion by midcentury, chiefly in developing countries already struggling to feed their people.
