Modulation of Resistance Genes: Two Paths to Alternaria Resistance in Apple
The Plant Cell, The Plant Cell: In BriefApple (Malus x domestica) is a major fruit crop worldwide that faces production losses due to many pathogens. Among them, Alternaria alternata is a fungal pathogen that causes necrotic leaf spots (see Figure), defoliation, and moldy fruit cores and constitutes a serious threat to orchards. Different…

Assembling a Nanomolecular Power Station
The Plant Cell, The Plant Cell: In BriefThe ATP synthase complex of chloroplasts is an elegant example of the union of structure and function at the molecular level (Junge and Nelson, 2015). This enzyme complex consists of an integral membrane CFo component that transports protons and an extrinsic CF1 component that synthesizes ATP (Hahn et…

Maintaining Cellular Phosphate
Research, The Plant Cell, The Plant Cell: In a NutshellSegami et al. investigate cellular phosphate homeostasis in Arabidopsis. Plant Cell https://doi.org/10.1105/tpc.17.00911
Background: Many biological reactions, including the biosynthesis of DNA, RNA, proteins, and polysaccharides, produce inorganic pyrophosphate (PPi). However, accumulation of PPi…
When Lipids Meet Hormones: Plants’ Answer to Complex Stresses
Research, The Plant Cell, The Plant Cell: In a NutshellWang et al. show that abscisic acid-inducible genes encode lipid degrading enzymes that release polyunsaturated fatty acids from chloroplast lipids as precursors for jasmonic acid production leading to biotic defenses in Arabidopsis.
