Evolution of petal patterning: blooming floral diversity at the microscale
New Phytologist, EarlyView.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.

Plant Biotechnology Journal, EarlyView.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.

Plants, Pollinators and Pheromones: Promises and Lies of Semiochemicals
Plant, Cell &Environment, EarlyView.ABSTRACT Pollination is traditionally regarded as a quintessential mutualism, yet many plants employ deceptive strategies to achieve reproductive success. Among the most intriguing is sexual deception, wherein flowers mimic the sex pheromones and visual signals of female insects to attract male pollinators—without providing any reward.

Dark side of anthocyanin pigmentation
Plant Biology, EarlyView.This review examines dark anthocyanin pigmentation in plants by outlining its distribution, exploring the genetic mechanisms behind its development, and discussing its ecological role together with its potential for various industrial applications. Abstract Dark pigmentation can be observed in various parts of the plant, ranging from foliage to petals ...

Plant Biology, EarlyView.Human‐invisible but bee‐visible UV patterns in flowers aid pollination by signalling to pollinators and protecting vulnerable DNA in pollen. ABSTRACT Ultraviolet light shining on flowers has various effects. In this review we assess functions of UV pigments and UV reflection patterns in flowers, including visual signalling by reflectance, fluorescence,

Plant Breeding Techniques in Tissue Culture to Improve the Quality of Orchids
Jurnal Ilmu Pertanian IndonesiaConventional orchid cultivation is thought to be ineffective and time-consuming. Simple tissue culture procedures are insufficient to increase orchid quality. The need for ongoing development can be met by integrating different plant breeding strategies

Are lichens biocompasses? Revisiting an old prediction using new techniques
Plant Biology, EarlyView.The equator‐facing portions of tree trunks receive direct sunlight and create restrictive microclimate conditions for lichens that orient preferentially towards the Earth's poles where trunks are shaded, indicating an optimal zone at the fine‐scale radial dimension.

Anther mimicry in an African orchid pollinated by pollen‐feeding beetles
Plant Biology, EarlyView.Beetles chew the fleshy yellow tips of an orchid's petals and pollinate its flowers, representing a novel case of pollen‐seeking beetles being deceived through anther mimicry. Abstract Flowers of many species have yellow markings that appear to mimic anthers or pollen and attract the attention of pollen‐seeking insects (usually female bees).
