Naturally occurring triploids in contact zones between diploid/tetraploid Odontophrynus cordobae and O. americanus (Anura, Odontophrynidae)
(Brill Academic Publishers, 2018-03-07)
Polyploidization plays an important role in speciation and evolution in anurans. However, a few stable triploid populations and some isolated triploid individuals have been reported. Here, we report the discovery of naturally ...
Are ploidy and age size-related? A comparative study on tetraploid Pleurodema kriegi and octoploid P. cordobae (Anura: Leptodactylidae) from Central Argentina
(Elsevier Gmbh, 2017-05)
Size differences of anuran amphibian complexes with different ploidy levels are well known, whereas the larger species usually corresponds to a lower ploidy level. Neotropical Pleurodema kriegi (tetraploid) and P. cordobae ...
Reproductive compatibility studies between wild and cultivated strawberries (Fragaria × ananassa) to obtain “bridge species” for breeding programmes
(Wiley Blackwell Publishing, Inc, 2019-04)
The Fragaria genus has become relevant due to worldwide economic importance of the octoploid hybrid F. × ananassa. Interspecific hybridizations are widely employed in breeding programmes to introduce useful characteristics ...
Flow cytometry : a useful tool measuring ploidy in Passiflora breeding programs
(2016-12)
La citometría de flujo en plantas permite un análisis rápido y sencillo del material genético de las plantas.
Para aplicar este método a plantas del género Passiflora, se pica finamente una porción de hoja y se pasa por ...
Nuclear ADN content and ploidy level in apomitic bufflegrass genotypesContenido de ADN nuclear y nivel de ploidía en genotipos apomícticos de buffelgrass
(Sociedad Mexicana de Fitogenética, 2018-01)
Buffelgrass [Pennisetum ciliare (L.) Link syn. Cenchrus ciliaris L.] is a polyploid fodder grass that has mostly apomictic reproduction. The wide genetic and cytological diversity present in the species indicates that the ...
Repetitive sequences in Eragrostis curvula cDNA EST libraries obtained from genotypes with different ploidy
(Springer, 2016-01)
Eragrostis curvula (Schrad) Nees (weeping lovegrass) represents important cultivated forage in semiarid regions, and the most useful cultivars are tetraploid and reproduce by pseudogamous diplosporous apomixis. We previously ...
Cryptic Haploid Stages in the Life Cycle of Leathesia marina (Chordariaceae, Phaeophyceae) Under In Vitro Culture
(Wiley Blackwell Publishing, Inc, 2020-10-28)
We evaluated the life cycle of Leathesia marina through molecular analyses, culture studies, morphological observations, and ploidy measurements. Macroscopic sporophytes were collected from two localities in Atlantic ...
Effects of ploidy and nutritional conditions on muscle morphology, proliferation and myogenic proteins expression in Rhamdia quelen larvae
(Elsevier Science, 2021-10)
Although Rhamdia quelen is a promising species for farming in South America, many aspects of its development and optimal conditions of culture remain unknown. In this sense, we explore muscle development and some proteins ...
