Broad spectrum resistance to fungal pathogens in sorghum is conferred by an immune receptor gene
Lee, Fu et al. discover an unusual immune receptor locus that confers broad-spectrum, strong resistance to fungal pathogens in sorghum.
Background: Sorghum, the fifth most widely grown cereal crop globally, provides food security for millions of people. The fungal disease sorghum anthracnose is the…
Nonessential genes are nevertheless good for something: Cold acclimation and photosynthesis
By Yang Gao and Reimo Zoschke, Max Planck Institute of Molecular Plant Physiology, Potsdam-Golm, Germany
Gao and colleagues dissect how transcription and translation of tobacco chloroplast genes respond to cold exposure and reveal a critical role for the nonessential gene petL.
Background: Plants…
An N-terminally truncated NLR is functional
Wu et al. uncover the unexpected role of the truncated NLR NRG1C in negatively regulating plant immunity by antagonizing its full-length NRG1 neighbors.
Background: Plants utilize sophisticated innate immune systems to fight against pathogens. Their genomes encode abundant immune receptors to detect…

WHITE-CORE RATE 1 regulates grain chalkiness in rice
Wu et al. uncover a mechanism underlying chalkiness, an important grain quality trait in rice.
Background: With improved living standards, the demand for better grain quality has become a challenge in rice production areas. Rice chalkiness, i.e., endosperm containing opaque regions, seriously reduces…
A role for MdMPK4s in apple peel coloration
Wang et al. investigate the role of MdMPK4 in fruit peel degreening during light/dark transitions
By Shuai Wang, Zhenhai Han and Ting Wu
Background: One of the most important visual indicators of fruit ripening in apple is the color change caused by anthocyanin accumulation and chlorophyll degradation.…
