The Metamorphosis of Flowers [PDF]

open access: yesThe Plant Cell, 1993
One of the unifying theories of plant biology is that the variety of plant forms are simply different modifications of a common growth plan. Different permutations of a few key features of plant growth can generate a bewildering array of seemingly distinct forms.

Functional significance of the optical properties of flowers for visual signalling

open access: yesAnnals of Botany, 2018
Background Flower coloration is a key enabler for pollinator attraction. Floral visual signals comprise several components that are generated by specific anatomical structures and pigmentation, and often have different functions in pollinator attraction.

Mining for Candidate Genes in an Introgression Line by Using RNA Sequencing: The Anthocyanin Overaccumulation Phenotype in Brassica

open access: yesFrontiers in Plant Science, 2016
Introgression breeding is a widely used method for the genetic improvement of crop plants; however, the mechanism underlying candidate gene flow patterns during hybridization is poorly understood. In this study, we used a powerful pipeline to investigate

Flowers and climate change: a metabolic perspective.

open access: yesNew Phytologist, 2019
Adverse climatic conditions at the time of flowering severely hinder crop yields and threaten the interactions between plants and their pollinators. These features depend on a common trait: the metabolism of flowers.

A Flower Sanctuary [PDF]

open access: yesNature, 1912
I BEG to thank Mr. Perrycoste for his letter in NATURE of September 19. The county of Somerset has for some time had a by-law similar to that of the county of Cornwall; but you will observe that the by-law does not justify the protection of any particular plant, and that the special flora of Cheddar might easily disappear without any violation of its ...

The influence of pigmentation patterning on bumblebee foraging from flowers of Antirrhinum majus [PDF]

open access: yes, 2013
Patterns of pigmentation overlying the petal vasculature are common in flowering plants,and have been postulated to play a role in pollinator attraction.

The Green Synthesis of MgO Nano-Flowers Using Rosmarinus officinalis L. (Rosemary) and the Antibacterial Activities against Xanthomonas oryzae pv. oryzae

open access: yesBioMed Research International, 2019
Recently, the use of herbs in the agriculture and food industry has increased significantly. In particular, Rosmarinus officinalis L. extracts have been reported to have strong antibacterial properties, which depend on their chemical composition.

Tobacco rattle virus-induced PHYTOENE DESATURASE (PDS) and Mg-chelatase H subunit (ChlH) gene silencing in Solanum pseudocapsicum L. [PDF]

open access: yesPeerJ, 2018
Virus-induced gene silencing (VIGS) is an attractive tool for determining gene function in plants. The present study constitutes the first application of VIGS in S. pseudocapsicum, which has great ornamental and pharmaceutical value, using tobacco rattle

Comprehensive analysis of the WRKY gene family in Cucumis metuliferus and their expression profile in response to an early stage of root knot nematode infection

open access: yesFrontiers in Plant Science, 2023
Root-knot nematode (RKN) is a major factor that limits the growth and productivity of important Cucumis crops, such as cucumber and melon, which lack RKN-resistance genes in their genome. Cucumis metuliferus is a wild Cucumis species that displays a high

Bee pathogen transmission dynamics: deposition, persistence and acquisition on flowers

open access: yesProceedings of the Royal Society B, 2019
Infectious diseases are a primary driver of bee decline worldwide, but limited understanding of how pathogens are transmitted hampers effective management.
