Phylogeographic analysis of the chloroplast DNA variation in wild common bean (Phaseolus vulgaris L.) in the Americas por Chacón Sánchez, María I., Pickersgill, B, Debouck, Daniel G., Arias, J.S.

“…Age estimates place the divergence of P. vulgaris from its sister taxa from Mesoamerica at or before 1.3 Ma, and divergence of populations from Ecuador-northern Peru at or before 0.6 Ma. As these ages are taken as minimum divergence times, the influence of past events, such as the closure of the Isthmus of Panama and the final uplift of the Andes, on the migration history and population structure of this species cannot be disregarded.…”

Early generation in vitro assay to identify potato populations and clones tolerant to heat por Khan, A., Munive, S., Bonierbale, Merideth W.

“…The results from true seed family level in vitro screening at 25 °C and tuber family evaluation under field conditions in Tacna, an arid sub-tropical environment in Southern Peru, were positively correlated (r = 0.57). There was low to moderate correlation between percentage of plants with tubers under 27 °C in vitro temperature treatment and harvest index in the in vivo conditions in Majes–Arequipa, San Ramon, and La Molina that followed increasing temperature ranges between the sites. …”
