Multi class intracellular protein targeting predictions in diatoms and other algae with complex plastids: ASAFind 2.0 [PDF]
Cells of diatoms and related algae with complex plastids of red algal origin are highly compartmentalized. These plastids are surrounded by four envelope membranes, which also define the periplastidic compartment (PPC), the space between the second and third membranes.

Comparison of different versions of SignalP and TargetP for diatom plastid protein predictions with ASAFind [PDF]
Plastid targeted proteins of diatoms and related algae can be predicted with high sensitivity and specificity using the ASAFind method published in 2015. ASAFind predictions rely on SignalP predictions of endoplasmic reticulum (ER) targeting signal peptides. Recently (in 2019), a new version of SignalP was released, SignalP 5.0.

Phytochrome activates the plastid-encoded RNA polymerase for chloroplast biogenesis via nucleus-to-plastid signaling. [PDF]
Light initiates chloroplast biogenesis by activating photosynthesis-associated genes encoded by not only the nuclear but also the plastidial genome, but how photoreceptors control plastidial gene expression remains enigmatic.

Aggregations of organelles in meiotic cells of higher plants
During early prophase I in microsporocytes and sporocytes of various plants all mitochondria and plastids aggregate in a group, where some plastids seem to undergo division. This group desintegrates by middle prophase I.

Comparative Analysis of Plastid Genomes Using Pangenome Research ToolKit (PGR-TK) [PDF]
Plastid genomes (plastomes) of angiosperms are of great interest among biologists. High-throughput sequencing is making many such genomes accessible, increasing the need for tools to perform rapid comparative analysis. This exploratory analysis investigates whether the Pangenome Research Tool Kit (PGR-TK) is suitable for analyzing plastomes.

New Insights Into Sunflower (Helianthus annuus L.) FatA and FatB Thioesterases, Their Regulation, Structure and Distribution [PDF]
Sunflower seeds (Helianthus annuus L.) accumulate large quantities of triacylglycerols (TAG) between 12 and 28 days after flowering (DAF). This is the period of maximal acyl-acyl carrier protein (acyl-ACP) thioesterase activity in vitro, the enzymes that

Metabolic engineering of p‐hydroxybenzoate in poplar lignin
Summary Ester‐linked p‐hydroxybenzoate occurs naturally in poplar lignin as pendent groups that can be released by mild alkaline hydrolysis. These ‘clip‐off’ phenolics can be separated from biomass and upgraded into diverse high‐value bioproducts. We introduced a bacterial chorismate pyruvate lyase gene into transgenic poplar trees with the aim of ...

How a simple chloroplast psbA gene mutation changed world agriculture [PDF]
Atrazine as a weed control tactic profoundly changed world agriculture. Long-term use revealed resistant biotypes, R, with a single base pair mutation of the chloroplast psbA gene. The R phenotype emerged from a sequential cascade of pleiotropic effects from the plastid to the whole plant.

The import and assembly of most of the mitochondrial proteome is regulated by protein translocases located within the mitochondrial membranes. The Presequence Translocase-Associated Motor (PAM) complex powers the translocation of proteins across the ...
