Advances in Bract Coloration: Diversity, Pigment Synthesis, and Regulatory Mechanisms in Ornamental Plants [PDF]

Plants
Bract coloration in ornamental plants is a complex trait governed by diverse pigments (chlorophylls, anthocyanins, betalains, and carotenoids), their biosynthetic pathways, and regulatory networks.

Mining and expression analysis of color related genes in Bougainvillea glabra bracts based on transcriptome sequencing [PDF]

Scientific Reports
Bract coloration is one of the key ornamental traits in Bougainvillea, yet research has predominantly focused on phenotypic color traits and pigment composition, with limited understanding of the molecular mechanisms underlying color formation.

Pantranscriptome combined with phenotypic quantification reveals germplasm kinship and regulation network of bract color variation in Bougainvillea [PDF]

Frontiers in Plant Science, 2022
Bracts are the metamorphic non-flower organ in angiosperm plants. The variation of the color and shape of bracts was found to be neo-functionalized (i.e., similar to petals), garnering research interest as a pollinator attractor.

Analysis of Pigmentation Changes in Bracts of Bougainvillea × buttiana ‘Miss Manila’ During Different Developmental Periods [PDF]

Biology
Bougainvillea has large and vibrant-colored bracts, which are widely used in landscape gardening. In order to study the changing pattern of pigmentation and the expression of genes related to pigment synthesis during different developmental periods of ...

Hybrid de novo transcriptome assembly of poinsettia (Euphorbia pulcherrima Willd. Ex Klotsch) bracts

BMC Genomics, 2019
Background Poinsettia is a popular and important ornamental crop, mostly during the Christmas season. Its bract coloration ranges from pink/red to creamy/white shades.

Effect of different soil water potential on leaf transpiration and on stomatal conductance in poinsettia

Acta Agrobotanica, 2013
Euphorbia pulcherrima Wild.'Lilo' was grown in containers in 60% peat, 30% perlite and 10% clay (v/v) mixture, with different irrigation treatments based on soil water potential. Plants were watered at two levels of drought stress: -50kPa or wilting. The

The rare orange-red colored Euphorbia pulcherrima cultivar ‘Harvest Orange’ shows a nonsense mutation in a flavonoid 3’-hydroxylase allele expressed in the bracts

BMC Plant Biology, 2018
Background Commercially available poinsettia (Euphorbia pulcherrima) varieties prevalently accumulate cyanidin derivatives and show intense red coloration. Orange-red bract color is less common.

Genome-Wide Identification of the MYB Gene Family in Bougainvillea and Silencing-Based Evidence for the Involvement of BbMYB6 and BbMYB69 in Yellow and Red Bract Coloration

Horticulturae
MYB transcription factors (TFs) serve pivotal regulatory functions in plant pigmentation; however, the composition of the MYB family in Bougainvillea spp. and the regulatory mechanisms underlying bract coloration have not yet been systematically examined.

Pollen Morphology of Crucianella L. (Rubiaceae) Based on Light and Scanning Electron Microscope Data and Implications for Taxonomy

Microscopy Research and Technique, EarlyView.
This study provides the palynological analysis of 12 Crucianella L. taxa using LM and SEM. Variations in pollen size, aperture number, and exine ornamentation were identified as key traits, demonstrating their taxonomic value for distinguishing closely related species and subspecies within the genus. ABSTRACT Crucianella L.
