GOLVEN peptide signaling through RGI receptors and MPK6 restricts asymmetric cell division during root initiation (Nature Plants)

Lateral root starts development starts with an asymmetric cell division in the founder cell. In this study, Fernandez et al. explored the role of peptide signaling this process. The authors started with the previous finding that GOLVEN peptides are involved in lateral root initiation, as overexpression…

Melatonin represses oil and anthocyanin accumulation in seeds (Plant Physiol.)

Seed oils and anthocyanins play several roles in plant physiology and are promising substances for crop engineering given their benefits for human health. Recent studies proposed that melatonin –a potent antioxidant present in all plant species– regulates the deposition of these metabolites in seeds,…

MYB30 negatively regulates photomorphogenesis by interacting with PIFs and phytochromes in Arabidopsis (Plant Cell)

Photomorphogenesis is the growth and development of plants in response to light. The phytochrome family of photoreceptors absorbs red and far-red light, and in Arabidopsis the most abundant phytochromes are phyA and phyB. PHYTOCHROME-INTERACTING FACTORS (PIFs) repress photomorphogenesis, and under red…

A moonlighting kinase induces immune responses in rice and Arabidopsis ($) (Plant Physiol.)

Bacterial infections are a serious issue for crop plants and it is thus imperative to understand the mechanisms employed by plants to develop resistance against pathogens. Malukani et al. have identified a receptor kinase in rice, WALL-ASSOCIATED KINASE-LIKE 21 (OsWAKL21.2) that perceives pathogen-induced…

Mechanistic insights into host perception by a fungal pathogen (PNAS)

Host perception is crucial for soil-borne microbes to successfully colonize plant roots. Ding et al. conducted transcriptome analysis of the fungal pathogen Fusarium graminearum (Fg) in the presence of its host plant Brachypodium distachyon (Bd), either without direct contact (precontact) or during colonization.…

MASS proteins and stomatal development in Arabidopsis (PLOS Genetics)

Stomata are the pores surrounded by a pair of guard cells on the plant epidermis that help in gaseous exchange. The number and spacing of stomata are regulated by a series of phosphorylation and de-phosphorylation events of key transcription factors through the mitogen-activated protein kinase (MAPK)…

Interplay between phosphorylation and ubiquitination is key for regulating reactive oxygen species during plant immunity (Nature Comms)

Reactive oxygen species (ROS) are essential secondary messengers for rapid transmission of local and long-distance signalling in plants. Respiratory oxidase homologs (RBOHs) are the family of enzymes in plants that produce extracellular ROS, with RBOHD being the primary oxidase in Arabidopsis for ROS…

A regulatory module for survival on low potassium (Nature Plants)

Potassium ions (K+) play a variety of important roles in plant physiology and are maintained at a high concentration in the cytosol relative to the available K+ in the environment. Potassium may accumulate to an even higher concentration in the vacuole, where it helps to regulate turgor pressure. During…

Extensive inter-plant protein transfer between Cuscuta parasites and their host plants (Mol. Plant)

Cuscuta (dodders) are parasites that survive on other host plants.Liu et al. found more than 1500 proteins are transferred between Cucuta and host plants forming a sort of interplant chemical communication. Furthermore, proteins could move between two hosts that are connected by dodder bridges, and retain…
