Shooting for the STARRs: A Modified STARR-seq Assay for Rapid Identification and Evaluation of Plant Regulatory Sequences in Tobacco Leaves

A single genome gives rise to different cell types and organs in response to precise temporal and spatial regulation of gene expression, driven by developmental and environmental cues. These expression patterns are orchestrated by cis-regulatory elements, distal enhancers and gene-proximal promoters.…

Glutelin mRNAs are transported on endosomes

Tian et al. identify the factors mediating localization of specific mRNAs in developing rice endosperm cells. Plant Cell https://doi.org/10.1105/tpc.20.00111  by Li Tian and Thomas W. Okita  Background: Localization of mRNAs is a universal mechanism to efficiently drive protein targeting in eukaryotes…

Sulfoxidation of NON-RIPENING Affects Tomato Fruit Ripening

Transcription factors (TFs) can be subject to multiple posttranslational modifications (PTMs) that affect protein stability, subcellular localization, interactions with corepressors and activators, and DNA binding activity of TFs, thereby influencing their regulatory activities on target genes. Recent…

An Intrinsically Disordered Protein Interacts with the Plant Cytoskeleton

Intrinsically disordered proteins lack a defined three-dimensional structure but often contain a simple amino acid composition with repeated  sequences that provide the basis for multivalent intermolecular interactions. Because of their unique structural flexibility, conformational adaptability, and…

A Peptide Hormone Receptor Controls Seed Size and Yield

Leucine-rich repeat receptor-like kinases (LRR-RLK) are one of the largest gene families in  plants. Research over the past decade has implicated LRR-RLKs and their selective interactions with secreted peptide hormones in a myriad of developmental processes. A conserved LRR-RLK with a burgeoning list…

Remorin and Plant Death

Programmed cell death (PCD) in plants is closely associated with a wide variety of biological processes, including cell differentiation, aleurone layer formation, tapetum degradation, leaf and fruit resistance, pathogen invasion and abiotic stresses. Plant PCD is a complex genetically programmed mechanism,…

Roots, Bacteria, Ethylene, and Rhizosheath Formation

The rhizosheath, the sticky part of the rhizosphere, is the layer of soil that adheres to roots upon excavation of the root system. The stickiness of the layer arises from mucilage and other substances secreted by roots, soil microbes or both. Rhizosheaths preferentially form in drier soil and  are…
