IN BRIEF
LARGE-SCALE BIOLOGY ARTICLES
- Metabolome-Scale Genome-Wide Association Studies Reveal Chemical Diversity and Genetic Control of Maize Specialized Metabolites
Metabolite profiling combined with genome-wide association studies provides a resource for structural and functional assignments of the many unknown metabolites in maize seedlings.
- A Comprehensive Map of Intron Branchpoints and Lariat RNAs in Plants
Analysis of 948 RNA sequencing data sets produced a comprehensive map of intron branchpoints and lariat RNAs in Arabidopsis thaliana, tomato, rice, and maize.
- High Temporal-Resolution Transcriptome Landscape of Early Maize Seed Development
High temporal-resolution transcriptomes uncover the genetic control of the developmental stages of double fertilization, coenocyte formation, cellularization, and differentiation in early maize seed.
RESEARCH ARTICLES
- Dynamics of Gene Expression in Single Root Cells of Arabidopsis thaliana
Single cell transcriptomic profiling can map developmental trajectories and assess cell-type–specific changes during heat shock at single cell resolution.
- Adaptation and Phenotypic Diversification in Arabidopsis through Loss-of-Function Mutations in Protein-Coding Genes
A large-scale study exploring how gene loss contributes to evolutionary change reveals that loss-of-function mutations contribute to the adaptation and phenotypic diversification of plants.
- OsSHI1 Regulates Plant Architecture Through Modulating the Transcriptional Activity of IPA1 in Rice
OsSHI1 represses the DNA binding activity of IPA1 to regulate plant architecture in rice.
- Tomato MYB21 Acts in Ovules to Mediate Jasmonate-Regulated Fertility
Jasmonate function is necessary for proper development of ovules in tomato and is at least partially mediated by SlMYB21 as revealed by analyses of different mutants, transcriptomics, and hormone measurements.
- Genetic Regulation of Ethylene Dosage for Cucumber Fruit Elongation
A RING-type E3 ligase ubiquitinates and degrades both itself and ACS2, thereby controlling the biosynthesis of ethylene, which fine-tunes cell division and fruit elongation in a dose-dependent manner.
- Rice qGL3/OsPPKL1 Functions with the GSK3/SHAGGY-Like Kinase OsGSK3 to Modulate Brassinosteroid Signaling
Rice qGL3 negatively regulates brassinosteroid signaling by regulating the phosphorylation level and stability of OsGSK3, which modulates OsBZR1 phosphorylation status and subcellular distribution.
- Glycome and Proteome Components of Golgi Membranes Are Common between Two Angiosperms with Distinct Cell-Wall Structures
Despite the large differences in the polysaccharide constituents of the cell walls of eudicots and grasses, the glycome profiles are common to Golgi membranes from both Arabidopsis and maize.
- Arabinosyl Deacetylase Modulates the Arabinoxylan Acetylation Profile and Secondary Wall Formation
Rice DARX1 is a GDSL esterase that trims acetyl groups from excess acetylated arabinosyl substituents of arabinoxylan and modulates xylan conformation and secondary wall architecture.
- The bZIP1 Transcription Factor Regulates Lipid Remodeling and Contributes to ER Stress Management in Chlamydomonas reinhardtii
The mRNA of a Chlamydomonas bZIP transcription factor is spliced by CrIRE1 under ER stress, and the resulting protein protects Chlamydomonas cells from ER stress by modulating lipid remodeling.
- The Chromatin-Associated Protein PWO1 Interacts with Plant Nuclear Lamin-like Components to Regulate Nuclear Size
Chromatin and Polycomb-group–associated component PWO1 is functionally connected to nuclear lamina member CRWN1 via genetic and physical interaction, transcriptomic control, and subnuclear localization.
- The Transcription Factors TCP4 and PIF3 Antagonistically Regulate Organ-Specific Light Induction of SAUR Genes to Modulate Cotyledon Opening during De-Etiolation in Arabidopsis
The developmental regulator TCP4 binds to and activates SAUR genes to facilitate cotyledon opening in the light, but high levels of the transcription factor PIF3 inhibit this binding in the dark.
- Identification of Molecular Integrators Shows that Nitrogen Actively Controls the Phosphate Starvation Response in Plants
Identification of molecular integrators shows that nitrogen actively controls the phosphate starvation response in plants.
