Seed size is regulated by siRNAs from Arabidopsis maternal tissue in a spatial-temporal manner ($)(PNAS)

Studying seed development is important for understanding plant evolution and engineering food production. Previous discoveries have shown that maternal small interfering RNAs (siRNAs), which induce RNA-directed DNA methylation (RdDM) through NRPD1-mediated pathway, regulate seed development in Arabidopsis.…

The Arabidopsis thaliana pan-NLRome; towards exploring NLR diversity in plants (bioRxiv)

Nucleotide-binding leucine-rich repeat (NLRs) receptors are involved in the intracellular recognition of pathogen effectors. Hundreds of genes encode these NLRs, and the genes are highly polymorphic. So far, a limited number of NLRs were characterized, and three mechanisms of effector recognition have…

KAI2 regulates root and root hair development by modulating auxin distribution (bioRxiv)

To optimize growth, plant development is regulated by environmental information. Root morphology is adaptable to stimuli due to a network of phytohormone signalling pathways. Here Villaecija et al. studied the roles of strigolactones (SL) and karrikins (KL) signalling in controlling root and root hair…

EU regulatory approach to directed mutagenesis: consequences for international trade and potential steps forward (New Phytol)

The seed sector, and particularly plant breeders, are responsible for providing farmers with new plant varieties able to overcome challenges such as climate change, water restrictions or plant pests. In order to do their job, breeders have a collection of tools at their disposal. Among these are traditional…

­Single-cell RNA sequencing resolves molecular relationships among individual plant cells (Plant Physiol)

Single cell RNA sequencing (scRNA-seq) has transformed our understanding of gene expression within and amongst individual cells. These techniques have been applied extensively to animal cell populations to discover the development of specific cell lines and identify rare cell types but are not commonly…

The genome of broomcorn millet: The fourth millet to be sequenced (Nature Comms)

Whole genome sequencing (WGS) unlocks the repertoire of genes encoded within the genome. From a structural genomics aspect, the sequence data enables the development of molecular markers and maps, and identification of novel QTLs/genes/alleles regulating the trait-of-interest. From a functional genomics…

Tapping into the genetic diversity of wild crops for engineering disease resistance (Nature Biotech)

Lack of sequence information makes harnessing the diversity of disease resistance (R) genes in wild crops highly challenging. Arora and Steuernagel et al. report AgRenSeq, a reference genome-free technique, for rapid cloning of nucleotide binding/Leucine-rich repeat (NLR) resistance genes from wild…

SOL1 and SOL2 regulate fate transition and cell division in stomatal lineage ($) (Development)

Stomata and pavement cell development in the leaves occur through programmed asymmetric cell division. In this paper the authors demonstrated the role of two CHC domain proteins, SOL1 and SOL2 that were identified previously by the same group to be downstream targets of a bHLH transcriptional factor…

Light regulates plant alternative splicing through the control of transcriptional elongation (Mol Plant)

Light perception in plants generates a plethora of gene expression changes. Among them, it has been shown that light affects alternative splicing mediated by a chloroplast retrograde signal. Here, Godoy Herz et al. explore the different possible mechanisms possible involved in this regulation. Using…
