Nectary Development in Petunia and Arabidopsis, a Sweet Story!
Research, The Plant Cell, The Plant Cell: In a NutshellMorel et al. study the nectar-producing organs in flowers and identify major regulators of nectary size https://doi.org/10.1105/tpc.18.00425
By Patrice Morel and Michiel Vandenbussche
Background: Nectaries are the organs that produce nectar, a sugary substance that motivates pollinators such as…
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…
Gatekeepers of Storage Lipids in Seeds: The Switch-Off Mechanism
Research, The Plant Cell, The Plant Cell: In a NutshellDeruyffelaere et al. investigate lipid mobilization during seed germination. Plant Cell https://doi.org/10.1105/tpc.18.00275
By Sabine D’ANDREA and Corine ENARD
Background: In cells, storage lipids are compartmentalized in specialized organelles called lipid droplets (LDs). The structure…

Uncovering the Steps Before: Sulfate Induces ABA Biosynthesis and Stomatal Closure
The Plant Cell, The Plant Cell: In BriefPlant stomatal aperture regulation via guard cells is an example of how plants dynamically process environmental signals to induce a physiological response. The drought stress hormone abscisic acid (ABA) is a well-characterized signal that induces stomatal closure, preventing water loss. ABA acts via…
A Partnership for ABA Responses
The Plant Cell: In BriefThe phytohormone abscisic acid (ABA) regulates a variety of processes in plants including seed dormancy, seedling growth, and response to environmental stresses. A fascinating study by Ni et al. (2018) shows that ABA responses in rice are regulated by an interaction between the DMI3 kinase, which activates…
