The polyploidy and its key role in plant breeding
(Planta, 2018)
A protocol for the in vitro propagation and polyploidization of an interspecific hybrid of Glandularia (G. peruviana×G. scrobiculata)
(Elsevier Science, 2015-03)
The genus Glandularia (Verbenaceae) has more than 50 species and it holds great ornamental potential due to its colorful flowers, long flowering period and low water requirements. Since the floriculture market avidly seeks ...
Molecular confirmation of species status for the allopolyploid cotton species, Gossypium ekmanianum Wittmack.
(Springer, 2014-06)
Understanding the relationship between domesticated crop species and their wild relatives is paramount to germplasm maintenance and the utilization of wild relatives in breeding programs. Recently, Gossypium ekmanianum was ...
The role of triploids in the origin and evolution of polyploids of Turnera sidoides complex (Passifloraceae, Turneroideae)
(Springer Tokyo, 2017-08)
Triploids can play an important role in polyploid evolution. However, their frequent sterility is an obstacle for the origin and establishment of neotetraploids. Here we analyzed the microsporogenesis of triploids (x=7) ...
Relationships in Patagonian species of Berberis (Berberidaceae) based on the characterization of rDNA internal transcribed spacer sequences
(Wiley Blackwell Publishing, Inc, 2007-03)
Sequence analysis of the internal transcribed spacer (ITS) of the 18S(ITS1)-5.8S 26S(ITS2) rDNA region was performed in order to analyse the phylogenetic relationships between 13 Patagonian species of the genus Berberis ...
Variation in the amino acids, volatile organic compounds and terpenes profiles in induced polyploids and in Solanum tuberosum varieties
(Pergamon-Elsevier Science Ltd, 2020-12)
Polyploids often display a variety of phenotypic novelties when compared to their diploid progenitors, some of which may represent ecological advantages, especially regarding tolerance to biotic and abiotic factors. Plants ...
Indução de poliploidia em protocormos de Cattleya nobilior
(Universidade Estadual Paulista (Unesp), 2022-07-08)
A exuberância da Cattleya nobilior vem garantindo a ela mais espaço e relevância no mercado ornamental. Porém características almejadas como tamanho das flores, bem como sua intensidade de cor, podem ser acentuadas quando ...
Phenotypic and epigenetic variation induced in newly synthesized allopolyploids and autopolyploids of potato
(Elsevier Science, 2018-04)
Polyploidy is one of the most important events in plant evolution: the evidence suggests that more than 70% of the angiosperms underwent some event of genomic duplication during their diversification. In potato, the third ...
