Cross‐continental variation of herbivore resistance in a global plant invader

Ecography, EarlyView.
While successful plant invasions often occur in novel environments, invasive species usually occupy broad niches within their native and introduced ranges. A better understanding of the process of invasion therefore requires a wide sampling of ranges, and a good knowledge of introduction history.

Genetic Manipulation of the Chloroplast Genome

, 1989
Publisher Summary This chapter discusses the genetic manipulation of the chloroplast genome. Chloroplasts are one of a group of organelles, the plastids, which are vital for the metabolic functioning of plants. Chloroplasts are the site of photosynthesis and many biosynthetic reactions, but other, non-green plastids also carry out essential metabolic

The Mitochondrial Genome of Cathaya argyrophylla Reaches 18.99 Mb: Analysis of Super-Large Mitochondrial Genomes in Pinaceae [PDF]

arXiv
Mitochondrial genomes in the Pinaceae family are notable for their large size and structural complexity. In this study, we sequenced and analyzed the mitochondrial genome of Cathaya argyrophylla, an endangered and endemic Pinaceae species, uncovering a genome size of 18.99 Mb, meaning the largest mitochondrial genome reported to date.

Protein import into bacterial endosymbionts and evolving organelles

The FEBS Journal, EarlyView.
The acquisition of bacterial endosymbionts by ancient host cells followed by massive adaptation of the partners gave rise to mitochondria and plastids. Today, various systems with younger and less integrated endosymbionts provide insights into the initial steps in the endosymbiont to organelle transition.

Phylogenetic relationships and characterization of the complete chloroplast genome of strawberry, Fragaria x ananassa (Rosaceae: Fragaria)

Mitochondrial DNA. Part B. Resources, 2019
Strawberry (Fragaria x ananassa) is an economically and important fruit species that is grown extensively around the entire world. In this study, we obtained the complete chloroplast genome of F. x ananassa. The chloroplast genome of F. x ananassa is 155,

High Spatio-Temporal-Resolution Detection of Chlorophyll Fluorescence Dynamics from a Single Chloroplast with Confocal Imaging Fluorometer [PDF]

arXiv, 2016
Chlorophyll fluorescence (CF) is a key indicator to study plant physiology or photosynthesis efficiency. Conventionally, CF is characterized by fluorometers, which only allows ensemble measurement through wide-field detection. For imaging fluorometers, the typical spatial and temporal resolutions are on the order of millimeter and second, far from ...

Tracing the evolutionary pathway: on the origin of mitochondria and eukaryogenesis

The FEBS Journal, EarlyView.
This study examines the stepwise transition from archaeal–bacterial associations to the emergence of eukaryotic cells. Metabolic cooperation and endosymbiosis fostered ecological and genetic integration, with extensive gene transfer reshaping host biology.

Eukaryotes evade information storage-replication rate trade-off with endosymbiont assistance leading to larger genomes [PDF]

arXiv
Genome length varies widely among organisms, from compact genomes of prokaryotes to vast and complex genomes of eukaryotes. In this study, we theoretically identify the evolutionary pressures that may have driven this divergence in genome length.

Characterisation of components and mechanisms involved in redox-regulation of protein import into chloroplasts [PDF]

, 2009
The vast majority of chloroplast proteins is encoded in the nucleus and thus has to be posttranslationally imported into the organelle, a process that is facilitated by two multimeric protein machineries, the Toc and Tic complexes (translocon at the ...
