Phenotypic selection under two contrasting environments in wild sunflower and its crop‐wild hybrid
(Wiley Blackwell Publishing, Inc, 2019-06-05)
Hybridization is a common phenomenon in plants and can lead to the introgression of alleles from one population into another, generate new hybrid lineages, or cause species extinction. The environmental conditions and the ...
Heat stress effects on reproductive traits in cultivated and wild sunflower (Helianthus annuus L.): evidence for local adaptation within the wild germplasm
(Springer, 2018-08-01)
Heat stress (HS) is a major threat to current and future crop production. Crop improvement for HS tolerance is a major tool for dealing with HS and crop wild relatives (CWR) offer the greatest variability for such improvement. ...
Intentional and unintentional selection during plant domestication: herbivore damage, plant defensive traits and nutritional quality of fruit and seed crops
(Wiley Blackwell Publishing, Inc, 2021-05)
Greater susceptibility to herbivory can arise as an effect of crop domestication. One proposed explanation is that defenses decreased intentionally or unintentionally during the domestication process, but evidence for this ...
Genetic variation for tolerance to extreme temperatures in wild and cultivated sunflower (Helianthus annuus) during early vegetative phases
(Csiro Publishing, 2020-06-04)
The increased incidence of extreme temperature events due to global climate change poses a major challenge for crop production. Ability to increase temperature tolerance through genetic improvement requires understanding ...
Response to water deficit of semi-desert wild potato Solanum kurtzianum genotypes collected from different altitudes
(Elsevier Ireland, 2021-07)
Drought-sensitive crops are threatened as a consequence of limited available water due to climate change. The cultivated potato (Solanum tuberosum) is susceptible to drought and within its wild relative species, Solanum ...
In situ conservation of wild potato germplasm in Argentina: Example and possibilities
(Elsevier, 2015-01)
The potato is the third most important food crop worldwide and in situ conservation of its wild relatives is considered an urgent priority. Although regions of the Americas with high wild potato species richness have been ...
Maternal control of early life history traits affects overwinter survival and seedling phenotypes in sunflower (Helianthus annuus L.)
(Wiley Blackwell Publishing, Inc, 2021-03)
When cultivated and wild plants hybridize, hybrids often show intermediate phenotypic traits relative to their parents, which make them unfit in natural environments. However, maternal genetic effects may affect the outcome ...
Modelled distributions and conservation status of the wild relatives of chile peppers ( Capsicum L.)
(Wiley Blackwell Publishing, Inc, 2019-11)
Aim: To fill critical knowledge gaps with regard to the distributions and conservation status of the wild relatives of chile peppers (Capsicum L.).Location: The study covered the potential native ranges of currently ...
Phenotypic selection under two contrasting environments in wild and crop-wild hybrid sunflower
(Ecological Society of America, 2019)
Hybridization is common in plants and can lead to the introgression of alleles from one population into another, generate new hybrid lineages, or cause species extinction. The environment and genetic background can influence ...
Unravelling quinoa domestication with wild ancestors
(CABI, 2016)
This chapter approaches quinoa (Chenopodium quinoa) domestication asking three questions: (1) What do we know about quinoa genetic structure, relations among related species and phylogenetics?, (2) What is known about ...
