A key feature of RNA interference is its ability to spread from cell to cell. Such non-cell-autonomous
gene silencing has been characterized extensively in both plants and animals, but …

In both animals and plants, many developmentally important regulatory genes have
complementary microRNAs (miRNAs), which suggests that these miRNAs constitute a class of …

High-throughput single-cell RNA sequencing (scRNA-seq) is becoming a cornerstone of
developmental research, providing unprecedented power in understanding dynamic processes…

The flattening of leaves results from the interaction between upper (adaxial) and lower (abaxial)
domains in the developing primordium. These domains are specified by conserved, …

The flattening of leaves results from the juxtaposition of upper (adaxial)and lower (abaxial)
domains in the developing leaf primordium. The adaxial-abaxial axis reflects positional …

Background Long non-coding RNAs (lncRNAs) are transcripts that are 200 bp or longer, do
not encode proteins, and potentially play important roles in eukaryotic gene regulation. …

MicroRNAs and trans-acting siRNAs (ta-siRNAs) have important regulatory roles in
development. Unlike other developmentally important regulatory molecules, small RNAs are not …

The regulation of members of the knotted1-like homeobox (knox) gene family is required for
the normal initiation and development of lateral organs. The maize rough sheath2 (rs2) gene…

KNOTTED1-like homeobox (KNOX) genes promote stem cell activity and must be repressed
to form determinate lateral organs. Stable KNOX gene silencing during organogenesis is …

Small RNAs are important regulators of gene expression. In maize, adaxial/abaxial (dorsoventral)
leaf polarity is established by an abaxial gradient of microRNA166 (miR166), which …
