Tanacetum cinerariifolium Schultz Bip.

, 2021
2.1. Morphological and anatomical analysis of T. cinerariifolium flowers The T. cinerariifolium flower head is supported by a long peduncle rising from the base of the plant, and composed of an outer ring of white ray florets and a yellow flower heart densely populated by disk florets in the center of the receptacle (Fig. 1A). Both disk and ray florets

Paraphoma Crown Rot of Pyrethrum (Tanacetum cinerariifolium) [PDF]

Plant Disease, 2016
Pyrethrum (Tanacetum cinerariifolium) is commercially cultivated for the extraction of natural pyrethrin insecticides from the oil glands inside seed. Yield decline has caused significant yield losses in Tasmania during the last decade. A new pathogen of pyrethrum causing crown rot and reduced growth of the plants in yield decline affected fields of ...

Identification of multiple odorant receptors essential for pyrethrum repellency in Drosophila melanogaster.

PLoS Genetics, 2021
Pyrethrum extract from dry flowers of Tanacetum cinerariifolium (formally Chrysanthemum cinerariifolium) has been used globally as a popular insect repellent against arthropod pests for thousands of years.

In situ characterisation of whole‐plant stomatal responses to VPD using leaf optical dendrometry

Plant, Cell &Environment, Volume 46, Issue 11, Page 3273-3286, November 2023., 2023
Abstract Vapour pressure deficit (VPD) plays a crucial role in regulating plant carbon and water fluxes due to its influence on stomatal behaviour and transpiration. Yet, characterising stomatal responses of the whole plant to VPD remains challenging due to methodological limitations.

Plant terpene specialized metabolism: complex networks or simple linear pathways?

The Plant Journal, Volume 114, Issue 5, Page 1178-1201, June 2023., 2023
SUMMARY From the perspectives of pathway evolution, discovery and engineering of plant specialized metabolism, the nature of the biosynthetic routes represents a critical aspect. Classical models depict biosynthesis typically from an end‐point angle and as linear, for example, connecting central and specialized metabolism. As the number of functionally

CmERF5‐CmRAP2.3 transcriptional cascade positively regulates waterlogging tolerance in Chrysanthemum morifolium

Plant Biotechnology Journal, Volume 21, Issue 2, Page 270-282, February 2023., 2023
Summary Waterlogging stress affects plant growth by limiting root respiration and reducing yield and economic value. Therefore, identifying genes involved in regulating waterlogging stress is vital. This study reports the ethylene‐responsive VII transcription factor (CmRAP2.3) in the chrysanthemum.

Establishment of an efficient genetic transformation system for Tanacetum cinerariifolium

Plant Cell, Tissue and Organ Culture (PCTOC), 2023
Abstract The Dalmatian Daisy Tanacetum cinerariifolium is an Asteraceae plant species that produces the natural insecticide “pyrethrum”, which is effective against mosquito disease vectors and household pests. To enhance the content of pyrethrum in flowers, a more detailed understanding of the mechanisms underlying pyrethrum biosynthesis is ...

Mega‐sized pericentromeric blocks of simple telomeric repeats and their variants reveal patterns of chromosome evolution in ancient Cycadales genomes

The Plant Journal, Volume 112, Issue 3, Page 646-663, November 2022., 2022
Significance Statement Telomeric sequences, typically found at chromosome ends, play an essential role in genome integrity. We studied their abundance across land plants and observe large blocks of telomeric repeats at centromere positions, particularly on telocentric chromosomes of cycads.

Genome sequencing reveals chromosome fusion and extensive expansion of genes related to secondary metabolism in Artemisia argyi

Plant Biotechnology Journal, Volume 20, Issue 10, Page 1902-1915, October 2022., 2022
Artemisia argyi is a medicinal plant with huge economic value. Here, Miao et al construct a chromosome‐level genome of A. argyi, revealing the chromosome fusion event and extensive expansion of genes related to flavonoids and terpenoids synthesis. Summary Artemisia argyi, as famous as Artemisia annua, is a medicinal plant with huge economic value in ...
