Allocation of Heme is Differentially Regulated by Ferrochelatase Isoforms in Arabidopsis Cells

Frontiers in Plant Science, 2016
Heme is involved in various biological processes as a cofactor of hemoproteins located in various organelles. In plant cells, heme is synthesized by two isoforms of plastid-localized ferrochelatase, FC1 and FC2.

A Holistic Investigation of Arabidopsis Proteomes Altered in Chloroplast Biogenesis and Retrograde Signalling Identifies PsbO as a Key Regulator of Chloroplast Quality Control. [PDF]

Plant Cell Environ
ABSTRACT Communication between the diverse compartments of plant cells relies on an intricate network of molecular interactions that orchestrate organellar development and adaptation to environmental conditions. Plastid‐to‐nucleus signalling pathways play a key role in relaying information from developing, mature, and damaged or disintegrating ...

A molecular phylogenetic study of Deschampsia (Poaceae: Aveneae) inferred from nuclear ITS and plastid trnL sequence data: support for the recognition of Avenella and Vahlodea [PDF]

, 2007
The circumscription and phylogeny of Deschampsia were studied for the first time by parsimony analysis of nuclear ribosomal internal transcribed spacer (ITS) and plastid trnL intron sequences.

Chloroplasts are central players in sugar-induced leaf growth [PDF]

, 2016
Leaves are the plant's powerhouses, providing energy for all organs through sugar production during photosynthesis. However, sugars serve not only as a metabolic energy source for sink tissues but also as signaling molecules, affecting gene expression ...

TaIRE1‐mediated unconventional splicing of the TabZIP60 mRNA and the miR172 precursor regulates heat stress tolerance in wheat

Journal of Integrative Plant Biology, EarlyView.
In wheat, INOSITOL‐REQUIRING ENZYME 1 (IRE1) helps plants cope with heat stress by regulating unconventional splicing of the mRNA encoding the bZIP transcription factor TabZIP60, which activates heat‐responsive genes, and cleavage of the precursor of the microRNA miR172 during heat stress.

Cryo‐SEM and large volume FIB‐SEM of Arabidopsis cotyledons: Degradation of lipid bodies, biogenesis of glyoxysomes and reorganisation of organelles during germination

Journal of Microscopy, EarlyView.
Abstract Until recently, the lack of three‐dimensional visualisation of whole cells at the electron microscopic (EM) level has led to a significant gap in our understanding of the interaction of cellular organelles and their interconnection. This is particularly true with regard to the role of the endoplasmic reticulum (ER).

Reminiscent of the pre‐diatom? A hitherto undescribed scaly bolidophyte Lepidoparma frigida gen. et sp. nov. in a new order Lepidoparmales based on morphology, phylogeny, and ecology

Journal of Phycology, EarlyView.
Abstract The class Bolidophyceae, which consists of small phytoplankton distributed worldwide, is the sister group of diatoms. This class has contained only one order, the Parmales, until now. In this study, we established a new order Lepidoparmales Kamakura & S.Sato ord. nov. and a new family Lepidoparmaceae Kamakura & S.Sato fam.

A Set of Plastid Loci for Use in Multiplex Fragment Length Genotyping for Intraspecific Variation in Pinus (Pinaceae)

Applications in Plant Sciences, 2014
Premise of the study: Recently released Pinus plastome sequences support characterization of 15 plastid simple sequence repeat (cpSSR) loci originally published for P. contorta and P. thunbergii.

Nutrient‐driven growth and microbiome shifts in the brown alga Sargassum fluitans III

Journal of Phycology, EarlyView.
Abstract Since 2011, holopelagic Sargassum has been accumulating in a region of the tropical Atlantic now referred to as the Great Atlantic Sargassum Belt (GASB). Among the hypothesized contributors to these accumulations are the increased inputs of nitrogen (N) and phosphorus (P) in the tropical Atlantic Ocean.

Microscopic Analyses of Fruit Cell Plastid Development in Loquat (Eriobotrya japonica) during Fruit Ripening

Molecules, 2019
Plastids are sites for carotenoid biosynthesis and accumulation, but detailed information on fruit plastid development and its relation to carotenoid accumulation remains largely unclear.
