Loss of the IR region in conifer plastomes: Changes in the selection pressure and substitution rate of protein-coding genes. [PDF]

Ecol Evol, 2022
There are significant differences in the selection pressure of 12 genes and the evolution rate of 9 genes between conifer and non‐conifer. This difference seems to be not related to the loss of typical IR regions but related to habitat. And the newly obtained short IR region plays a role in stabilizing the genome.

Phylogenetic reconciliation provides new insights into the evolutionary diversification of the glutamine synthetase gene family in seed plants. [PDF]

FEBS J
Phylogenetic analyses of glutamine synthetase (GS) in seed plants revealed that all three major evolutionary lineages (GS2, GS1a, and GS1b) must have been present in the common ancestor, with GS2 being the first lineage to diverge. Unlike GS1b, GS1a and GS2 are usually single‐copy genes, even though they underwent duplications that resulted in ...

Rapid Dereplication of Bioactive Compounds in Plant and Food Extracts Using Liquid Chromatography-Electrospray-Tandem Mass Spectrometry. [PDF]

Anal Sci Adv
ABSTRACT High‐throughput screening and identification of common phytochemicals are crucial for lead optimization, drug development and investigation of metabolic pathways in complex herbal extracts. The available databases contain a huge number of compounds, making it challenging and time‐consuming to dereplicate valuable compounds.

Commodity risk assessment of bonsai plants from China consisting of Pinus parviflora grafted on Pinus thunbergii

EFSA Journal, Volume 20, Issue 2, February 2022., 2022
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver a scientific opinion on the risk posed by bonsai plants from China consisting of Pinus parviflora grafted on Pinus thunbergii taking into account the available scientific information, including the technical information provided by China.

[Retracted] Artificial Neural Network‐Based Planting Arrangement of Smart City in Green Ecological Environment

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
The traditional urban planting arrangement is largely limited by the designer’s idea and has a high repetition rate and a low reference reuse rate. Therefore, a scientific and reasonable planting arrangement of the urban environment is necessary. In this work, research on planting arrangements in a smart city is carried out under green ecology and ...

A new subfamily classification of the Citrus family (Rutaceae) based on six nuclear and plastid markers

TAXON, Volume 70, Issue 5, Page 1035-1061, October 2021., 2021
Abstract Rutaceae is a family of angiosperms well known for the economically important genus Citrus. The division of Rutaceae into subfamilies is still inadequate and provisional. Previous phylogenetic studies at the family level are characterized by a limited sampling of genera and lack several crucial taxa. Here, we present a phylogenetic study based

Pest categorisation of <i>Pyrrhoderma noxium</i>. [PDF]

EFSA J
Abstract Following the commodity risk assessment of bonsai plants (Pinus parviflora grafted on Pinus thunbergii) from China performed by EFSA, the EFSA Plant Health Panel performed a pest categorisation of Pyrrhoderma noxium, a clearly defined plant pathogenic basidiomycete fungus of the order Hymenochaetales and the family Hymenochaetaceae.

Overlooked Parrot Seed Dispersal in Australia and South America: Insights on the Evolution of Dispersal Syndromes and Seed Size in Araucaria Trees

Frontiers in Ecology and Evolution, 2019
While Psittaciformes (parrots and allies) are well-recognized as highly-mobile seed predators, their role as seed dispersers has been overlooked until very recently.

Distinguishing the Woods of Araucaria Cunninghamii (Hoop Pine) and Araucaria Bidwilli (Bunya Pine)

IAWA Journal, 1995
Araucaria today is endemic to the Southern Hemisphere, with three species in Australia. Araucaria cunninghamii Ait. ex D.Don (Hoop Pine) and A. bidwilli Hook. (Bunya Pine) were cut in the past and marketed together as Colonial Pine. Today only A. cunninghamii is cut commercially, mainly from plantations established in the last few decades.
