Application of TurboID-mediated proximity labeling for mapping a GSK3 Kinase signaling network in Arabidopsis (bioRxiv)

In this preprint Kim et al., have provided an optimized method for determining protein-protein interaction in plants using TurboID-mediated labelling.  TurboID is an engineered promiscuous biotin ligase that marks proteins it comes in contact with. Identification of interacting partners of a protein…

HORT1 retrotransposon causes harlequin/black flowers in Phalaenopsis orchids (Plant Physiol)

Phalaenopsis orchids produce beautiful, long-lived flowers and are widely popular houseplants. In 1996, a new variety was identified with intensely dark, nearly black pigmentation. Hsu et al. have identified the molecular basis for this phenotype; a Gypsy-like retrotransposon inserted in the promoter…

Characterizing the serotonin biosynthesis pathway upon aphid infestation in Setaria viridis leaves (bioRxiv)

In response to biotic stresses, plants produce chemical defenses to reduce damage. Adaptations to insect infestation involve synthesis of Trp-derived metabolites, leading to metabolome alterations. Here, Dangol et al. analyzed the transcriptomic and metabolomic effects after herbivore feeding in Setaria…

Arabidopsis FLL2 promotes liquid–liquid phase separation of polyadenylation complexes ($) (Nature)

The nucleus of plants cells, like other eukaryotes, is full of non-membranous compartments separated by liquid-liquid phases. These complexes are often called nuclear bodies and concentrate proteins and nucleic acids. Disordered protein domains play a critical in their formation. Here, Fang et al. aimed…

Review. Chemical convergence between plants and insects: biosynthetic origins and functions of common secondary metabolites (New Phytol)

Plants and insects aren't closely related, but they have a plethora of similar chemical weapons used for their interactions (defense, attraction, etc.). Beran et al. describe the function and biosynthesis of secondary metabolites that are shared in both insects and plants. The monoterpenes and…

Diverse metabolites across maize GWAS panel for dissecting maize genetic architecture (Plant Cell)

Plants can produce metabolites that are directly involved in various biological pathways. Identifying variations of specific metabolites in different genotypes would facilitate the understanding underlying complex genetic architecture of maize. One of most representative natural diversity panels, the…

Generating novel, dual herbicide-resistant crops using CRISPR-mediated gene editing (Plant Physiol)

There is an ever-growing need for novel herbicides as more weeds are becoming resistant to commonly used herbicides. In a recent report from Hu et al., the authors identified that a previously described cellulose biosynthesis-inhibiting chemical, C17, possesses an herbicidal quality. The authors showed…

Complete biosynthesis of cannabinoids and their unnatural analogues in yeast (Nature) ($)

Cannabis sativa L. produces cannabinoid compounds that interest the medical community for the treatment of symptoms that may be difficult to suppress with common medical treatments. Research on cannabinoids is limited by their low abundance in plant tissue and structurally complex chemical synthesis.…

Ubiquitin-dependent chloroplast-associated protein degradation in plants (Science) ($)

The fidelity of the chloroplast proteome is a major factor in the functional efficiency of photosynthesis. A RING-type ubiquitin E3 ligase, SP1, is an outer envelope localized protein in the chloroplast which ubiquitinates the protein import translocases (TOC proteins) and thus target them to 26S mediated…
