Evolution of petal patterning: blooming floral diversity at the microscale

New Phytologist, Volume 247, Issue 6, Page 2538-2556, September 2025.
Summary The flowers of angiosperms are extraordinarily diverse. While most floral variation is visible to the naked eye, this diversity goes beyond the macroscale: Floral organs comprise an underappreciated range of cell types that generate a multitude of patterns across their surfaces and give rise to novel structures.

Impact of Nitrate and Ammonium ratio on Nutrition and Growth of two Epiphytic Orchids

Anais da Academia Brasileira de Ciências, 2018
Phalaenopsis and Dendrobium do not grow and flower well with 100% ammonium (NH4-N); and there are detailed studies on the effects of nitrate (NO3-N) and ammonium ratios on the flowering, but no information about accumulation of other nutrients and the ...

Evidence of purifying selection and co-evolution at the fold-back arm of the novel precursor microRNA159 gene in Phalaenopsis Species (Orchidaceae). [PDF]

PLoS ONE, 2014
MicroRNAs (miRNAs) are small, endogenously transcribed, non-protein-coding RNAs that play important roles in regulation of gene expression in animals and plants.

The road less taken: Dihydroflavonol 4‐reductase inactivation and delphinidin anthocyanin loss underpins a natural intraspecific flower colour variation

Molecular Ecology, Volume 34, Issue 15, August 2025.
Abstract Visual cues are of critical importance for the attraction of animal pollinators, however, little is known about the molecular mechanisms underpinning intraspecific floral colour variation. Here, we combined comparative spectral analysis, targeted metabolite profiling, multi‐tissue transcriptomics, differential gene expression, sequence ...

Resolving floral development dynamics using genome and single‐cell temporal transcriptome of Dendrobium devonianum

Plant Biotechnology Journal, Volume 23, Issue 8, Page 2997-3011, August 2025.
Summary Dendrobium devonianum, a species of the Orchidaceae family, is notable for its unique floral characteristics, which include two yellow spots and purple tips on its labellum, as well as fringed edges. However, the molecular mechanisms underlying flower pattern formation in D.

Integrative omics reveals mechanisms of biosynthesis and regulation of floral scent in Cymbidium tracyanum

Plant Biotechnology Journal, Volume 23, Issue 6, Page 2162-2181, June 2025.
Summary Flower scent is a crucial determiner in pollinator attraction and a significant horticultural trait in ornamental plants. Orchids, which have long been of interest in evolutionary biology and horticulture, exhibit remarkable diversity in floral scent type and intensity. However, the mechanisms underlying floral scent biosynthesis and regulation

Automated mass spectrometry‐based profiling of multi‐glycosylated glycosyl inositol phospho ceramides (GIPC) reveals specific series GIPC rearrangements during barley grain development and heat stress response

The Plant Journal, Volume 122, Issue 6, June 2025.
Significance Statement This study introduces an automated method for detailed profiling of complex glycosyl inositol phosphor ceramides (GIPC), revealing their structural diversity and dynamic roles in barley grain development and stress responses. By advancing our understanding of GIPC in membrane stability and stress adaptation, this work provides a ...

Transcriptional Reprogramming Deploys a Compartmentalized ‘Timebomb’ in Catharanthus roseus to Fend Off Chewing Herbivores

Plant, Cell &Environment, Volume 48, Issue 5, Page 3236-3256, May 2025.
ABSTRACT The evolutionary arms race between plants and insects has led to key adaptive innovations that drive diversification. Alkaloids are well‐documented anti‐herbivory compounds in plant chemical defences, but how these specialized metabolites are allocated to cope with both biotic and abiotic stresses concomitantly is largely unknown.
