Proteins that Function in Lipid Droplets
Research, The Plant Cell, The Plant Cell: In a NutshellKretzschmar et al. study the proteome of lipid droplets and identify a protein that functions in protein degradation during germination https://doi.org/10.1105/tpc.18.00276
Background: Lipid droplets (LDs) are structures inside cells that store oil or fat, for example, in oil seeds. They were once…

Towards Pathogen-Resistant Apples
Research, The Plant Cell, The Plant Cell: In a NutshellZhang et al. show that a single-nucleotide polymorphism in a hairpin RNA promoter contributes to Alternaria alternata leaf spot resistance in apple and could serve as a marker to distinguish susceptible versus resistant apple cultivars. https://doi.org/10.1105/tpc.18.00042.
Background: Apple Alternaria…
Assembling a Nanomolecular Power Station

Background: The F-type ATP synthase produces nearly all of the cellular ATP, the universal energy currency…
How Peroxisomes Modulate Chloroplast Activity in a Microalga
Research, The Plant Cell, The Plant Cell: In a NutshellBackground: Chloroplasts are the major powerhouse of plant and algal cells, where photosynthesis—the conversion of carbon dioxide into organic compounds using sunlight energy—occurs. Chloroplasts are also where important cell components (such as membrane lipids and pigments) and energy-rich compounds…
