Automated color detection in orchids using color labels and deep learning

open access: yesPLoS ONE, 2021
The color of particular parts of a flower is often employed as one of the features to differentiate between flower types. Thus, color is also used in flower-image classification. Color labels, such as ‘green’, ‘red’, and ‘yellow’, are used by taxonomists

Transgenerational Plasticity in Flower Color Induced by Caterpillars

open access: yesFrontiers in Plant Science, 2021
Variation in flower color due to transgenerational plasticity could stem directly from abiotic or biotic environmental conditions. Finding a link between biotic ecological interactions across generations and plasticity in flower color would indicate that

Flowering Phenology and the Influence of Seasonality in Flower Conspicuousness for Bees

open access: yesFrontiers in Plant Science, 2021
Flowering patterns are crucial to understand the dynamics of plant reproduction and resource availability for pollinators. Seasonal climate constrains flower and leaf phenology, where leaf and flower colors likely differ between seasons.

Phenotypic Diversity Analysis of the Progeny Variation of a ‘Mosaic Leaf’ Loropetalum chinense var. rubrum Based on Flower Organ Characteristics

open access: yesDiversity, 2022
Loropetalum chinense var. rubrum is a common landscape plant. Because of the preference for the ‘red leaf’ trait, the ‘flower color’ trait was ignored in breeding, and the genetic diversity of L. chinense var.

Transcription and Metabolic Profiling Analysis of Three Discolorations in a Day of Hibiscus mutabilis

open access: yesBiology, 2023
In this study, we used combined transcriptomics and metabolomics to analyze the H. mutabilis cultivar’s genetic and physiological mechanisms during three flower color transition periods (from white to pink, then from pink to red) within the span of one ...
