Reactive oxygen species (ROS) regulate plant growth and development. ROS are kept at
low levels in cells to prevent oxidative damage, allowing them to be effective signaling …

Chloroplasts are the metabolically active, semi-autonomous organelles found in plants,
algae and cyanobacteria. Their main function is to carry out the photosynthesis process …

Plant carotenoids are a family of pigments that participate in light harvesting and are
essential for photoprotection against excess light. Furthermore, they act as precursors for the …

Chlamydomonas reinhardtii is a unicellular green alga whose lineage diverged from land
plants over 1 billion years ago. It is a model system for studying chloroplast-based …

Tocopherols (vitamin E) are lipid soluble antioxidants synthesized by plants and some
cyanobacteria. We have earlier reported that overexpression of the γ-tocopherol methyl …

There are 244 cytochrome P450 genes (and 28 pseudogenes) in the Arabidopsis genome.
P450s thus form one of the largest gene families in plants. Contrary to what was initially …

Plastoglobuli (PGs) are plastid lipoprotein particles surrounded by a membrane lipid
monolayer. PGs contain small specialized proteomes and metabolomes. They are present in …

During the past decade, there has been a paradigm shift in our understanding of the roles of
intracellular lipid droplets (LDs). New genetic, biochemical and imaging technologies have …

During leaf senescence, chlorophyll is removed from thylakoid membranes and converted in
a multistep pathway to colorless breakdown products that are stored in vacuoles …

During leaf senescence, plants degrade chlorophyll to colorless linear tetrapyrroles that are
stored in the vacuole of senescing cells. The early steps of chlorophyll breakdown occur in …
