More than symbioses : orchid ecology ; with examples from the Sydney Region [PDF]

open access: yes, 2013
The Orchidaceae are one of the largest and most diverse families of flowering plants. Orchids grow as terrestrial, lithophytic, epiphytic or climbing herbs but most orchids native to the Sydney Region can be placed in one of two categories.

Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen‐rewarding Caribbean bloodwort

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Reproductive assurance through autogamous self-pollination across diverse sexual and breeding systems [PDF]

open access: yes, 2015
Pollination becomes a constraint when conspecific plants and/or their pollinators become scarce. Many plant species have evolved autogamous self-pollination as a means of reproductive assurance (RA) under pollination-uncertain environments. So far RA has

Phylogenomics, ecomorphological evolution, and historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae)

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

Autonomous pollination alleviates pollen limitation in the endemic Cienfuegosia yucatanensis Millsp. (Malvaceae)

open access: yesBotan‪ical Sciences, 2020
Background: Self-compatibility is common on endemic plant species, but pollen limitation and self-pollination could be risk factors. Study species: The endemic Cienfuegosia yucatanensis (Malvaceae), whose distribution is mainly restricted to the ...

Development of Artificial Intelligence for Quantitative Assessment of Nasal Inflammatory Cytology in Chronic Rhinitis by Whole‐Slide Images

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinitis (CR) is currently recognized as a syndrome that manifests in different phenotypes. We aimed to establish an artificial intelligence system (quantitative assessment of nasal inflammatory cytology, QANIC) on the basis of whole‐slide images (WSIs) to enable quantitative assessment of nasal inflammatory cells.

A Thornless Trifoliate Orange from Self-pollination

open access: yesHortScience, 1985
Abstract A thornless variant of the trifoliate orange [Poncirus trifoliata (L.) Raf.] was found as a chance seedling. All other characters were indistinguishable from those of normal trifoliate. Genotypes of the variant at loci controlling GOT isozymes were PP,SS, whereas those of the normal trifoliate orange have been reported to be MP,SM. The variant

Cenh3: An Emerging Player in Haploid Induction Technology. [PDF]

open access: yes, 2016
True-breeding lines are required for the development and production of crop varieties. In a classical breeding approach these lines are obtained through inbreeding, and often 7-9 generations of inbreeding is performed to achieve the desired level of ...

Local Specific IgE Levels Can Predict and Monitor the Therapeutic Response to Subcutaneous Immunotherapy With House Dust Mite

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Identifying predictive and monitoring biomarkers for allergen immunotherapy response is crucial for enhancing clinical efficacy. This study aims to investigate the systemic and local levels of immunoglobulins and identify potential biomarkers in house dust mite (HDM) allergic rhinitis (AR) patients who are undergoing subcutaneous ...
