Nanoscale movements of cellulose microfibrils in primary cell walls ($)

/
Cell walls are complex mixtures of cellulose microfibrils, proteins and other materials. Their mechanical properties can be measured and modeled, but it is not always simple to translate these measurements to changes at the molecular level. Zhang et al. used atomic force microscopy to provide an unprecedented…

Drop-Seq for plants: High-throughput, single cell transcriptomics (Cell Reports)

Drop-Seq is an exciting high-throughput technology for single cell transcriptomics. Using microfluidics, single cells are encapsulated in drops with beads carrying “bar-coded” primers. The RNA from each individual cell is labeled with a unique primer code, then sequenced. Now, Shulse et al. have…

High-temporal-resolution transcriptome landscape of early maize seed development (Plant Cell)

Seeds determine the yield and quality of the plants. In maize, seed development initiates from a double fertilization event where one pollen sperm fuses with the egg and the other with the central cell of female gametophyte to produce the progenitors of embryo and endosperm, respectively. The embryo…

Single-cell RNA sequencing reveals developmental trajectories of Arabidopsis root cells

New advances in sequencing technologies have made possible the understanding of the dynamics of developmental processes in an unprecedented manner. In a recent study, Denyer, Ma, et al. profiled nearly 5,000 cells from Arabidopsis roots using single-cell RNA sequencing technology. Gene expression profiles…
