Plant scientists are rapidly integrating single-cell RNA sequencing (scRNA-seq) into their workflows. Maximizing the potential of scRNA-seq requires a proper understanding spatiotemporal context cells. However, positional information is inherently lost during scRNA-seq, limiting its to characterize complex biological systems. In this review we highlight how current analysis pipelines cannot completely recover spatial information, which confounds interpretation. Various strategies exist identify location RNA, from classical in situ hybridization transcriptomics. Herein discuss possibility utilizing supervise analyses. An integrative approach will maximize each technology, and lead insights go beyond capability individual technology.

Single-cell RNA-sequencing datasets of Arabidopsis roots have been generated, but related comprehensive gene co-expression network analyses are lacking. We conducted a single-cell analysis with publicly available scRNA-seq using SingleCellGGM algorithm. The identified 149 modules, which we considered to be expression programs (GEPs). By examining their spatiotemporal expression, GEPs specifically expressed in major root cell types along developmental trajectories. These define regulating development at different stages and enriched relevant regulators. As examples, GEP specific for the quiescent center (QC) contains 20 genes QC stem niche homeostasis, four sieve elements (SEs) from early late stages, early-stage containing 17 known SE also metabolic pathways cell-type-specific suggesting existence metabolism roots. Using GEPs, discovered verified columella-specific gene, NRL27, as regulator auxin-related gravitropism response. Our thus systematically reveals that regulate provides ample resources biology studies.

Legume plants establish an endosymbiosis with nitrogen-fixing rhizobia bacteria, which are taken up from the environment anew by each host generation. This requires a dedicated genetic program on side to control microbe invasion, involving coordinated reprogramming of cells create infection structures that facilitate inward movement symbiont. Infection initiates in epidermis, different legumes utilizing distinct strategies for crossing this cell layer, either between (intercellular infection) or transcellularly (infection thread infection). Recent discoveries plant using fluorescent-based imaging approaches have illuminated spatiotemporal dynamics infection, underscoring importance investigating process at dynamic single-cell level. Extending fluorescence-based live-dynamic bacterial partner opens exciting prospect learning how individual reprogram rhizospheric host-confined state during early root infection.

ABSTRACT Legumes have the beneficial capacity to establish symbiotic interactions with rhizobia, which provide their host plants fixed nitrogen. However, in presence of nitrogen, this process is rapidly repressed avoid unnecessary investments carbon symbiosis. Several players involved regulating nodulation response nitrate availability been identified, including peptide hormones, microRNAs and transcription factors. Nevertheless, how these molecular are linked each other what underlying mechanisms at play inhibit remain unresolved. Nitrate‐mediated control seems differ between model legumes, such as Medicago Lotus , compared legume crops soybean. A deeper understanding regulatory processes, particularly soybean, expected contribute establishing increased efficiency modern agricultural systems, hence improving sustainability by reducing need for environmentally hazardous nitrogen fertilizers. This review describes state art nitrate‐regulated while drawing parallels described legumes addressing knowledge gaps that require future study.
