NITRATE TRANSPORT 1/PTR FAMILY (NPF) substrates are very diverse, and include nutrients, secondary metabolites and hormones.

Number of NRT1/PTR FAMILY (NPF) homologs found in different species of red algae and viridiae plants. The homologs have been classified based on a BLASTP against Arabidopsis using the classification established by Léran et al. (2014).

Very happy to see our work out examining guard cell transcriptomes over the course of a slowly developing drought. Thanks to @bradylabs.bsky.social and @kaisakajala.bsky.social for the inspiration, way back in Davis in 2013! The data are available in bar.utoronto.ca/eplant & doi.org/10.1093/plce...

Fig. 1.Schematic diagram showing submerged treatment and leaf materials of H. difformis. Clonal-cutting seedlings grown under terrestrial conditions were grown under terrestrial or submerged conditions. The water levels for terrestrial and submerged conditions were maintained at the top of vinyl pots and near the top of the tank, respectively. After initial growth for 4 weeks, several pots with plants were transferred from terrestrial conditions to submerged conditions as the submerged treatment. Photographs show leaf samples that have been harvested and washed. Scale bars in the photographs=10 mm.

A single-cell multi-omics atlas of rice | Nature Cell functions across eukaryotes are driven by specific gene expression programs, which are dependent on chromatin structure1–3. Here we report a single-cell multi-omics atlas of rice, one of the world’s major crops. By simultaneously profiling chromatin accessibility and RNA expression in 116,564 cells from eight organs, we identified cell-type-specific gene regulatory networks and described novel cell states, such as a ‘transitional state’ in floral meristems. On the basis of our network analyses, we uncovered the function of the cell-type-specific regulatory hubs RSR1, F3H and LTPL120 during rice development. Our analysis revealed correlations between cell type and agronomic traits, as well as conserved and divergent cell-type functions during evolution. In summary, this study not only offers a unique single-cell multi-omics resource for a major crop but also advances our understanding of cell-type functions and the underlying molecular programs in rice.
