Oriental lily hybrids engineered to resist aphid attack [PDF]

, 2009
Establishing in vitro bulb scale cultures of lily cultivars followed by callusing and regeneration after gene transfer was found to be not very successful in our hands, except for ‘Snow Queen’.

Functional traits and soil water availability shape competitive interactions in a diploid–polyploid complex

Journal of Ecology, EarlyView.
Our study emphasises that the long‐term fate of polyploids largely depends on water availability, with high polyploids having a competitive advantage in arid environments. This ultimately highlights the role of functional traits in shaping the competitive dynamics between cytotypes.

Efficient haploid production on 'Wilking' mandarin by induced gynogenesis [PDF]

, 2015
Seedlessness is a major criterion for the citrus fresh fruit market. Therefore, triploid breeding appears very promising for the selection of new citrus cultivars.

Unreduced megagametophyte production in lemon occurs via three meiotic mechanisms, predominantly second-division restitution [PDF]

, 2017
Unreduced (2n) gametes have played a pivotal role in polyploid plant evolution and are useful for sexual polyploid breeding in various species, particularly for developing new seedless citrus varieties.

What are the consequences of water stress on the development of late postzygotic reproductive isolation in an orchid hybrid zone?

Plant Species Biology, EarlyView.
Hybrids vulnerable to drought may increase postzygotic isolation in hybrid zones. Drought experiments can reveal the influence of climate change on hybrid zones. Crassulacean acid metabolism in parental species and hybrids was negatively affected by drought.

Comparison of genetic and phenotypic variations in disjunct populations of highly polyploid Betula davurica in the Japanese Archipelago with continental populations in a region of northeast Asia

Plant Species Biology, EarlyView.
Betula davurica is widely distributed in continental regions of northeast Asia but is disjunctly distributed in the Japanese Archipelago. Disjunct Honshu populations are genetically divergent from continental populations in a continuously distributed region in Primorye although disjunct Hokkaido populations are not divergent. These disjunct populations

Molecular Method Based on Hydrolysis Probe Assays to Identify the Sex Chromosomes of Iberian Desman (Galemys pyrenaicus) Using Non‐Invasive Sampling

Integrative Zoology, EarlyView.
To monitor populations of an endangered species such as Galemys pyrenaicus in the Extremadura area, qPCR techniques have been used to determine sex, using non‐invasive sampling techniques. ABSTRACT Desmans belong to the subfamily Desmaninae, which are members of the family Talpidae.

Effects of ploidy level on leaf morphology, stomata, and anatomical structure of Hibiscus syriacus L.

BMC Plant Biology
Background Hibiscus syriacus L. is a deciduous shrub with a strong environmental resistance and wide application prospects. The genetic background and ploidy levels of Hibiscus cultivars are complex, and polyploid breeding has long been an important ...
