Rethinking plastid evolution [PDF]

open access: yesThe EMBO Reports, 2010
How easy is it to acquire an organelle? How easy is it to lose one? These questions underpin the current debate about the evolution of the plastid—that is, chloroplast—the organelle of photosynthesis in eukaryotic cells. The origin of the plastid has been traced to an endosymbiosis between a eukaryotic host cell and a cyanobacterial symbiont, the ...

Evolution: The plasticity of plastids

open access: yesCurrent Biology, 2023
Many chloroplast-bearing plants and algae lost their photosynthetic activity during evolution but retained their chloroplasts for other functions. A group of dinoflagellate algae apparently lost one half of their photosynthetic machinery but retained the other, providing a novel mechanism for light perception.

Seagrass species diversity in Tanzania based on morphological and molecular data

open access: yesNordic Journal of Botany, EarlyView.
Seagrass diversity along the Tanzanian coast has been documented mainly through morphology, with limited molecular reference data available for Tanzania and the wider Western Indian Ocean. This study combined morphological identification with nuclear ribosomal internal transcribed spacer (ITS) and plastid ribulose‐1,5‐bisphosphate carboxylase/oxygenase

Taxonomy and phylogeny of the intercontinental disjunctive ferns: series Reniformia Adiantum

open access: yesNordic Journal of Botany, EarlyView.
There are disputed opinions about the three taxa of series Reniformia, namely A. nelumboides X.C.Zhang (A. reniforme var. sinense Y.X.Lin), A. reniforme var. reniforme, and A. reniforme var. asarifolium (Willd.) R. Sim, owing to their similar morphology but intercontinental disjunctive distribution and close lineage with the series Venusta (only ...

The Glycerate and Phosphorylated Pathways of Serine Synthesis in Plants: The Branches of Plant Glycolysis Linking Carbon and Nitrogen Metabolism

open access: yesFrontiers in Plant Science, 2018
Serine metabolism in plants has been studied mostly in relation to photorespiration where serine is formed from two molecules of glycine. However, two other pathways of serine formation operate in plants and represent the branches of glycolysis diverging

Mazus dabieshanensis sp. nov. (Mazaceae) from eastern China

open access: yesNordic Journal of Botany, EarlyView.
Mazus dabieshanensis, a newly described species endemic to the Dabieshan Mountains in eastern China, is illustrated and described. Molecular phylogenetic analyses based on nuclear and chloroplast DNA sequences consistently demonstrate that this new species forms a stable clade with other Mazus species characterized by a pubescent ovary. Morphologically,

Plastid Division and Development [PDF]

open access: yesThe Plant Cell, 1999
Plastids are an important group of plant cellular organelles and comprise one of the primary features that distinguish plant cells from those of other eukaryotes. Plastids are thought to have arisen as a result of an endosymbiotic event in which an early photosynthetic prokaryote invaded a ...

Comprehensive DIA‐MS Proteomics of Root Basal Nodes Elucidates Mechanisms of Salt Tolerance in Rice

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Soil salinity severely affects rice growth, yield, and quality, posing a global food security challenge. Rice is particularly vulnerable to high salinity, which restricts growth and tolerance to other stresses. To address this, breeding efforts have been made in the past, leading to the generation of multi‐stress‐tolerant rice lines.

Gene turnover in the common ancestor of all C4 grasses

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Plastome phylogenomics and phylogenetic diversity of endangered and threatened grassland species (Poaceae) in a North American tallgrass prairie

open access: yesEcology and Evolution, 2020
Native grasslands are one of the most endangered ecosystems in North America. In this study, we examined the ecological and evolutionary roles of endangered and threatened (e/t) grasses by establishing robust evolutionary relationships with other ...
