Pollination biology and breeding system of syntopic Adenocalymma nodosum and A. peregrinum (Bignonieae, Bignoniaceae) in the Brazilian savanna
(Elsevier B.V., 2016-08-01)
The tropical Bignoniaceae is mostly late-acting self-incompatible (LSI) and depends on a guild of medium to large sized bees for their pollination. Adenocalymma nodosum and A. peregrinum are syntopic shrubs in savanna areas ...
Self-incompatibility, inbreeding depression and crossing potential in five Brazilian Pleurothallis (Orchidaceae) species
(Academic Press LtdLondonInglaterra, 2001)
Neighboring genes for DNA-binding proteins rescue male sterility in Drosophila hybrids

UGP gene expression and UDP-glucose pyrophosphorylase enzymatic activity in grafting annonaceous plants
(2016-03-01)
Grafting is commonly used to propagate commercial fruit species to ensure that the genetic characteristics of selected clones are maintained. However, the biochemical and molecular mechanisms involved in the graft ...
Molecular analysis of the rDNA ITS-1 intergenic spacer in Drosophila mulleri, D-arizonae, and their hybrids
(Kluwer Academic/plenum Publ, 2002-12-01)
We analyzed the ITS-1 spacer region of the rDNA in Drosophila mulleri and D. arizonae, two sibling species belonging to the mulleri complex (repleta group) and in hybrids obtained in both cross directions. In spite of ...

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 ...
Hybridization could be a common phenomenon within the highly diverse lizard genus Liolaemus
(Wiley Blackwell Publishing, Inc, 2018-06)
Hybridization is likely to occur more often between closely related taxa that have had insufficient time to diverge to the point of reproductive incompatibility; hybridization between deeply divergent lineages is rare. In ...
