Intra-population variability in the drought response of a beech (Fagus sylvatica L.) population in the southwest of Europe
(2017-06)Phenotypic variability within forest species populations is considered of special relevance for local adaptation under new environments, albeit it has been analyzed to a lesser extent than inter-population phenotypic ... -
Isolation and genetic characterization of Acidovorax avenae from red stripe infected sugarcane in Northwestern Argentina
(2013-11)Red stripe is a bacterial disease of sugarcane causing important economic losses in Argentina that affects 30 % of the milling stems and consequently the juice quality. In this study, sugarcane leaves exhibiting red stripe ... -
Local adaptation along a sharp rainfall gradient occurs in a native Patagonian grass, Festuca pallescens, regardless of extensive gene flow
(Elsevier, 2020-03)Increasing global aridity combined with changing environmental conditions might cause irreparable alterations in arid and semiarid ecosystems. Knowledge of within-species genetic diversity and adaptive responses, especially ... -
