Analysis of the Plastid Genome Sequence During Maize Seedling Development

Frontiers in Genetics, 2022
Shoot development in maize progresses from small, non-pigmented meristematic cells to expanded cells in the green leaf. During this transition, large plastid DNA (ptDNA) molecules in proplastids become fragmented in the photosynthetically-active ...

Removal of the large inverted repeat from the plastid genome reveals gene dosage effects and leads to increased genome copy number

Nature Plants
The chloroplast genomes of most plants and algae contain a large inverted repeat (IR) region that separates two single-copy regions and harbours the ribosomal RNA operon.

Plastid Genome Comparative and Phylogenetic Analyses of the Key Genera in Fagaceae: Highlighting the Effect of Codon Composition Bias in Phylogenetic Inference

Frontiers in Plant Science, 2018
Fagaceae is one of the largest and economically important taxa within Fagales. Considering the incongruence among inferences from plastid and nuclear genes in the previous Fagaceae phylogeny studies, we assess the performance of plastid phylogenomics in ...

Nuclear genome sequence of the plastid-lacking cryptomonad Goniomonas avonlea provides insights into the evolution of secondary plastids

BMC Biology, 2018
The evolution of photosynthesis has been a major driver in eukaryotic diversification. Eukaryotes have acquired plastids (chloroplasts) either directly via the engulfment and integration of a photosynthetic cyanobacterium (primary endosymbiosis) or ...

The non-photosynthetic, pathogenic green alga Helicosporidium sp. has retained a modified, functional plastid genome [PDF]

, 2004
A fragment of the Helicosporidium sp. (Chlorophyta: Trebouxiophyceae) plastid genome has been sequenced. The genome architecture was compared to that of both a non-photosynthetic relative (Prototheca wickerhamii) and a photosynthetic relative (Chlorella ...

Allelic Variation in Maize Malate Dehydrogenase 7 Shapes Promoter Methylation and Banded Leaf and Sheath Blight Resistance

Advanced Science, EarlyView.
In this study maize chloroplastic malate dehydrogenase7 (ZmMDH7), is identified as a Rhizoctonia solani resistance gene in maize. ZmMDH7 is regulated by transcription factor ZmWRKY44 via pathogens challenge to elevate mitochondrial ROS and SA signaling pathway.

Terniopsis chanthaburiensis (Podostemaceae), a new record for China and its complete plastid genome

Nordic Journal of Botany, EarlyView.
The genus Terniopsis consists of plants that have not been thoroughly studied, with many species remaining taxonomically unresolved. In this study, Terniopsis chanthaburiensis is reported as a new record of China based on morphological traits. Then, we assembled and annotated its chloroplast genome based on genome skimming data.

Phylogenomics and plastome evolution of Lithospermeae (Boraginaceae)

BMC Plant Biology
Background Lithospermeae is the largest tribe within Boraginaceae. The tribe has been the focus of multiple phylogenetic studies over the last 15 years, with most focused on one genus or a few genera.
