Arracacha (Arracacia xanthorrhiza)

The name is derived from the Quechua word rakacha. The upper part of the plant resembles its close relative celery.  Three main cultivars types of arracacha are found in the Andean valleys, “amarillo” (yellow), “blanco” (white), and “morado” (purple). In Brazil about 20 000 ha are sown annually. Arracacha starch is easy to digest and the root is rich in b-caroten, calcium, and starch. A major challenge with this crop is poor postharvest storability.

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
