Small Talk: Protons Help Calcium Get the Message Across
The Plant Cell, The Plant Cell: In BriefCalcium (Ca2+) is a versatile second messenger that controls a range of cellular processes—from pollen tube growth to stress responses—by regulating the activity of various proteins. Although Ca2+ is present at millimolar concentrations in the cell wall and vacuole, a set of channels, pumps, and…
Corn ChIPs and RNA-seq: Researchers Dip into Advanced Tools and Resources to Examine bZIP Transcription Factor Function in the Maize Endosperm
The Plant Cell, The Plant Cell: In BriefThe endosperm of maize (Zea mays) seeds undergoes a complicated developmental program that ends with the production of massive amounts of storage compounds, particularly carbohydrates, but also including zein storage proteins (reviewed in Li and Berger, 2012; Hannah and Boehlein, 2017; Larkins et al.,…
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
Research, The Plant Cell, The Plant Cell: In a NutshellZhang et al. investigate the assembly of a molecular motor that produces cellular ATP in chloroplasts https://doi.org/10.1105/tpc.18.00075.
By Lin Zhang, Lianwei Peng and Jean-David Rochaix
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…
Taking the TOC/TIC path to the chloroplast
