Independent genetic control of maize (Zea Mays L.) kernel weight determination and its phenotypic plasticity.
(Oxford University Press, 2014-06)
Maize kernel weight (KW) is associated with the duration of the grain-filling period (GFD) and the rate of kernel biomass accumulation (KGR). It is also related to the dynamics of water and hence is physiologically linked ...
Long-term dynamics of phenotype-dependent dispersal within a wild bird population
(Oxford Univ Press Inc, 2019-04)
Dispersers are not a random subset of the source population, and there is considerable evidence that they differ from non-dispersers in a number of phenotypic traits. However, it is not clear whether the magnitude and ...
A Potential Role for Phenotypic Plasticity in Invasions and Declines of Social Insects
(Frontiers Media S.A., 2019-10)
Eusociality, a form of animal social organization involving sterile and reproductive castes, is a rare, but highly ecologically successful form of life. There are striking examples of eusocial species with populations that ...
Phenotypic selection mosaic for flower length influenced by geographically varying hawkmoth pollinator proboscis length and abiotic environment
(Wiley Blackwell Publishing, Inc, 2019-09)
Biotic and abiotic context may affect the intensity of interspecific interactions and subsequently drive locally particular phenotypic selection patterns on interacting traits. We evaluated the geographical variation of ...
Same Phenotype in Children with Growth Hormone Deficiency and Resistance
(Hindawi Publishing Corporation, 2018-04)
By definition, about 2.5% of children show a short stature due to several causes. Two clinical conditions are characterized by serum IGF-I low levels, idiopathic GH deficiency (IGHD), and GH insensitivity (GHI), and the ...
Environmental fluctuations and their consequences for the evolution of phenotypic diversity
(Frontiers Media SA, 2017-05)
An essential aspect of the current theory of adaptive speciation is the maintenance of phenotypic variation and the evolution of stationary stable phenotypic diversity, a phenomenon known as evolutionary branching. Theoretical ...
Phenotyping for resistance to pre-harvest sprouting in grain sorghum
(Cambridge University Press, 2021-03)
Pre-harvest sprouting (PHS) is a common threat to cereal crops in which the grain maturation phase takes place under rainy, moist conditions. Susceptibility to PHS is higher in sorghum genotypes displaying low levels of ...
Canonical transient receptor potential 6 channel deficiency promotes smooth muscle cells dedifferentiation and increased proliferation after arterial injury
(Elsevier, 2020-07)
Objective Previous studies showed the benefit of canonical transient receptor potential 6 (TRPC6) channel deficiency in promoting endothelial healing of arterial injuries in hypercholesterolemic animals. Long-term studies ...
Dispersion, colonization and phenotypic structure of prehistoric human populations of the Andes of North-Western ArgentinaDispersion, colonization and phenotypic structure of prehistoric human populations of the andes of North-Western Argentina
(E. Schweizerbart'sche Verlagsbuchhandlung, 2018-12)
In this article we study the phenotypic structure, biological relationships and evolutionary factors that acted on the biological diversity observed in the prehistoric groups that inhabited Northwest Argentina (NWA). The ...
Assessment of phenotypic variability among EEA INTA Pergamino sunflower lines: Its relationship with the grain yield and oil content
(2021-05)
The aims of the present study were to assess the phenotypic diversity among 221 sunflower accessions of INTA Pergamino Sunflower Breeding Program, to obtain discriminant functions that allow the classification of new ...
