Maca (Lepidium meyenii)

This name is also a Quechua word. Maca is an annual herb but managed as a biennial crop. The first year maca grows vegetatively forming edible hypocotyls 6-8 months after planting. The second year maca grows reproductively and sets flowers and produces orthodox seeds. Maca cultivation is mostly restricted to the central Peruvian Andes (3500-4500 masl). Traditional uses include the putative enhancement of human and animal fertility. In Peru, about 3000 ha are sown annually. Global interest in maca is increasing rapidly. In 2014, more than 1200 patent applications related to maca were filed, mainly from China.

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
