The island syndrome in plants on New Zealand's outlying islands: a review

open access: yesNew Zealand Journal of Botany, Volume 63, Issue 5, Page 2300-2324, December 2025.
ABSTRACT The island syndrome is defined as a suite of predictable and consistent differences between island and mainland organisms. In seed plants, much of what we know about the island syndrome comes from work in the Southwest Pacific, which is comprised of the three main islands of New Zealand and ten surrounding archipelagos.

Evolution of Hybrid Inviability Associated With Chromosome Fusions

open access: yesMolecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Chromosomal rearrangements, such as inversions, have received considerable attention in the speciation literature due to their hampering effects on recombination. Less is known about how other rearrangements, such as chromosome fissions and fusions, can affect the evolution of reproductive isolation. Here, we use crosses between populations of

Mechanisms of sexual polyploidization and inheritance in triploid citrus populations [PDF]

open access: yes, 2015
Citrus is the main fruit crop in the world and Spain is the 6th producer and the major exporter for the fresh fruit market. Seedlessness is one of the most important fruit quality traits for this market since consumers do not accept seedy fruits. Recovery of triploid hybrids has become an important breeding strategy to develop new seedless citrus ...

Reproductive pathways inHieracium s.s.(Asteraceae): strict sexuality in diploids and apomixis in polyploids [PDF]

open access: yesAnnals of Botany, 2018
Apomixis or asexual seed reproduction is a key evolutionary mechanism in certain angiosperms providing them with reproductive assurance and isolation. Nevertheless, the frequency of apomixis is largely unknown, especially in groups with autonomous apomixis such as the diploid-polyploid genus Hieracium.Using flow cytometric analyses, we determined the ...

Challenges and prospects of endosperm balance number in potato (Solanum tuberosum) improvement

open access: yesThe Indian Journal of Agricultural Sciences, 2014
Endosperm Balance Number (EBN) is a genome-specific ploidy, which is not necessarily equivalent to the chromosome ploidy. The EBN is the ‘effective ploidy’ that determines crossability in Solanum species.

Human‐Mediated Dispersal Routes Structure Sahara Mustard Genomics

open access: yesMolecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Humans have facilitated the spread and evolution of invasive species, a pattern that has accelerated with the globalisation of trade and societal development. Consequently, the invasiveness of a species may be determined not only by how many propagules and which genotypes are introduced, but also by its evolutionary history and how humans have

Gametes with somatic chromosome number and their significance in interspecific hybridization in Fuchsia

open access: yesBiologia Plantarum, 2011
Sexual polyploidization has both a theoretical as well as an applied significance. Morphological screening for large pollen grains and shape of pollen produced by the individual, cytological investigation of hybrid progeny, and unbalanced separation of ...

Influence of water availability on gender determination of gametophytes in a diploid –polyploid complex of a xerophytic fern genus [PDF]

open access: yes, 2015
Environmental sex determination (ESD) is present in several animal and plant lineages. Diverse factors such as temperature, light or water availability have been described as sex determinants in these organisms. Among plants, ferns frequently display ESD.

Genome composition of triploid lily cultivars derived from sexual polyploidization of Longiflorum × Asiatic hybrids (Lilium) [PDF]

open access: yesEuphytica, 2007
About 19 cultivars, which had originated from backcrosses between F1 LA (Longiflorum × Asiatic) hybrids (2n = 2x = 24) as female parents and Asiatic cultivars as male parents (2n = 2x = 24), were analyzed with genomic in situ hybridization. 17 of them were triploid (2n = 3x = 36), and two aneuploid (2n = 3x + 1 = 37).
