Journal ArticleDOI
The advantages and disadvantages of being polyploid
TL;DR: The advantages and challenges of polyploidy, and its evolutionary potential, are considered.
Journal ArticleDOI
Pathways, mechanisms, and rates of polyploid formation in flowering plants
TL;DR: The results indicate that the triploid bridge pathway can contribute significantly to autopolyploids formation regardless of the mating system, and to allopolyploid formation in outcrossing taxa.
Journal ArticleDOI
Evidence for Extensive Overlap of Sporophytic and Gametophytic Gene Expression in Lycopersicon esculentum.
TL;DR: Male gametophyte (pollen) isozyme profiles were compared with those of the sporophyte for nine enzyme systems and all the genes tested were found to be expressed after meiosis, apparently transcribed and translated in the haploidgametophytes.
BookDOI
Polyploidy and genome evolution
TL;DR: This book discusses the evolution of genome and karyotype restructuring in Nicotiana tabacum L, and the early stages of polyploidy: rapid and repeated evolution in Tragopogon.
Journal ArticleDOI
Ecological studies of polyploidy in the 100 years following its discovery
Justin Ramsey,Tara S. Ramsey +1 more
TL;DR: A historical overview of hypotheses and empirical data regarding the ecology of polyploidy is presented, which revealed multi-faceted ecological and phenotypic differences, some of which may be direct consequences of genome duplication.

Chromosome behaviour and structural hybridity in the tradescantiae. II.
TL;DR: Fragments are small in Rhoeo and in the tetraploids, showing that the assumption of pairing and crossing-over being restricted to the end regions is justified and that the anaphase in some forms comes to correspond with the hollow metaphase in others.
Journal ArticleDOI
A Cytological and Genetical Study of Triploid Maize.
TL;DR: McClintock's Ph.D. thesis on a triploid maize plant was published in 1929 as this long article.
Journal ArticleDOI
Zytologische studien an allium schoenoprasum
TL;DR: Chromosome painting, as a direct and concise method in analysing chromosome structure abnormality, is an important complement and development of chromosome banding technique, and has important application in genetic counselling and prenatal diagnosis.
Journal ArticleDOI
The Assortment of Chromosomes in Triploid Daturas
TL;DR: The present article is the one of a number of proposed papers which will deal with the behavior of the chromnosomes in the different classes, of Datura mutants, the correlation of the chromosomal differences with changes in structural and other characters, and with the ratios in which Mendelian allelomorphs are found in the offspring.
Journal ArticleDOI
Chromosome Behaviour Due to a Gene Which Prevents Metaphase Pairing in Datura
TL;DR: In Datura stramonium a recessive gene (bd) which is located in the 21·22 chromosome, is responsible for a complete lack of pairing of homologous chromosomes during the first meiotic division in both microsporocytes (pollen-mother-cells) and megasporocytes.
