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.

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]
arXivMitochondrial 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.

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 ...

Journal of Integrative Plant Biology, EarlyView.Genomic evidence suggests that sex chromosomes may not be conserved within liverworts. Re‐evolution of dioicy in the genus Riccia may have occurred with probable de novo establishment of a new sex chromosome from the autosome, and the m‐chromosomes have evolved independently from chromosomes in the Marchantiales.

Insights into the genomic divergence of maize heterotic groups in China
Journal of Integrative Plant Biology, EarlyView.Seven core heterotic groups were differentiated in maize germplasm from China, and these groups showed regionality and uniqueness at the genomic level. The environmental adaptability of heterotic groups was improved by selection for more stress tolerance‐related genes for adaptation to the complex and changeable climate.

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