In this seminal paper, Roszak et al. present a deeper understanding of the development of the protophloem cell lineage. The differentiation process from the phloem stem cell to the enucleated cell state spans approximately 19 cells. Using live imaging, FACS sorting and single-cell RNA sequencing, the…

Many biological processes are controlled by the circadian clock in plants, yet studies often don't report sampling timepoints, leaving much to be discovered about the plant circadian rhythm. Apelt et al. have utilised single cell RNA sequencing to examine almost 70,000 Arabidopsis cells from above and…

Desert plants must produce seeds that can withstand incredibly high temperatures. Nevertheless, different species of cacti –one of the most emblematic plant groups of these ecosystems– exhibit variable responses to extreme temperatures. In this fascinating paper, Visscher and colleagues conduct a…

Plants have evolved well-coordinated crosstalk between different signaling pathways to respond and adapt to various environmental stresses. Brassinosteriods (BRs) and Target of Rapamycin Complex (TORC) have multiple roles, through transcription, translation and autophagy, to control the balance between…

Land plant evolution accompanied a plethora of evolutionary novelties such as cells that compose complex organs (e.g., stems, leaves, roots) and male/female gametophytes. The identity and conservation of the transcriptional programs underlying organogenesis and reproductive development across land plants…

Cis-regulatory elements (CREs) are DNA sequences found near or within genic regions that drive proper gene expression in time and space. Thus, CREs play essential roles in the diversification of spatially distinct cell-types with specialized function in multicellular organisms. To identify CREs underlying…

The outcome of a plant-bacteria interaction is determined by the bacterial virulence and plant immune systems. Individually, these systems, and to an extent their interactions, have been well studied. However, certain aspects of their interactions remain elusive, particularly how plant immunity affects…

Plants (embryophytes) are by definition multicellular, but we seek to understand them as the sum of the activities of individual cells. Much of this knowledge rests on information obtained through grinding up tissues  made up from several cell types. This review by Luo et al. describes methods for plant…
