Moss Chloroplasts Are Surrounded by a Peptidoglycan Wall Containing D-Amino AcidsA peptidoglycan wall surrounding each plastid in the moss Physcomitrella patens was visualized using metabolic labeling with a d-Ala-d-Ala dipeptide probe and click chemistry.
LARGE-SCALE BIOLOGY ARTICLES
Evolutionarily Distinct BAHD N-Acyltransferases Are Responsible for Natural Variation of Aromatic Amine Conjugates in RiceEight BAHD N-acyltransferases with diverse specificities, including four tryptamine/tyramine bifunctional N-acyltransferases, are present in the Gramineae.
A Sorghum Mutant Resource as an Efficient Platform for Gene Discovery in GrassesSequencing of 256 sorghum mutant families uncovered 1.8 million mutations, providing an efficient resource for causal gene/SNP variant to trait association with wide application to cereal crops.
RESEARCH ARTICLES
The Slicer Activity of ARGONAUTE1 Is Required Specifically for the Phasing, Not Production, of Trans-Acting Short Interfering RNAs in ArabidopsisAmplified short interfering RNAs are made in the absence of RNA cleavage activity of ARGONAUTE1, implying that recruitment of RNA-dependent RNA Polymerase 6 does not require RNA cleavage fragments.
SMAX1-LIKE7 Signals from the Nucleus to Regulate Shoot Development in Arabidopsis via Partially EAR Motif-Independent MechanismsThe strigolactone signaling target, SMXL7, signals from the nucleus to regulate diverse aspects of shoot development through mechanisms that in part do not require its conserved EAR motif.
CLAUSA Is a MYB Transcription Factor That Promotes Leaf Differentiation by Attenuating Cytokinin SignalingThe tomato CLAUSA gene encodes a unique MYB transcription factor that promotes leaf differentiation by attenuating cytokinin response.
Circadian Stress Regimes Affect the Circadian Clock and Cause Jasmonic Acid-Dependent Cell Death in Cytokinin-Deficient Arabidopsis PlantsStrong changes in the light-dark regime negatively affect the circadian clock, causing circadian stress, which leads to jasmonic acid-dependent cell death in cytokinin-deficient Arabidopsis plants.
Global Regulation of Plant Immunity by Histone Lysine Methyl TransferasesArabidopsis histone methyl transferases SET DOMAIN GROUP8 and 25 regulate pep1-, flg22-, and effector-triggered immunity as well as systemic acquired resistance through regulation of the basal and induced transcriptome.
Arabidopsis HOOKLESS1 Regulates Responses to Pathogens and Abscisic Acid through Interaction with MED18 and Acetylation of WRKY33 and ABI5 ChromatinArabidopsis HOOKLESS1 contributes to plant immunity and responses to the stress hormone ABA and is a critical component of the transcription complex modulating defense gene expression.
Biosynthesis of 8-O-Methylated Benzoxazinoid Defense Compounds in MaizeA genome-wide quantitative trait mapping strategy revealed a side branch of the benzoxazinoid pathway in maize that specifically increases maize resistance against aphids.
The Arabidopsis Malectin-Like/LRR-RLK IOS1 Is Critical for BAK1-Dependent and BAK1-Independent Pattern-Triggered ImmunityThe receptor-like kinase IOS1 is critical for priming of Arabidopsis thaliana innate immunity and is required for optimal function of BAK1-dependent and BAK1-independent cell surface immune receptors.
Arabidopsis CSLD5 Functions in Cell Plate Formation in a Cell Cycle-Dependent MannerCell cycle-regulated CSLD5 provides essential cell wall synthase activity for cell plate formation during cytokinesis.
Multiple Calmodulin-Binding Sites Positively and Negatively Regulate Arabidopsis CYCLIC NUCLEOTIDE-GATED CHANNEL12A cyclic nucleotide-gated channel that regulates plant immunity has multiple C-terminal calmodulin domains and is regulated both positively and negatively by calmodulin, challenging the current model.
