Maize, as a C4 plant, possesses two distinct types of photosynthetic cells, the mesophyll (M) and the bundle sheath (BS) cells. To elucidate their functional and regulatory differentiation we isolated large quantities of highly homogeneous M and BS cells from new mature leaves for transcriptome prof...

Histone acetylation and methylation regulate gene expression in eukaryotes, but their effects on the transcriptome of a multicellular organism and on the transcriptomic divergence between species are still poorly understood. Here we present the first genome-wide 1-bp resolution maps of histone acety...
ORGANISM(S): Arabidopsis thaliana 
Deep sequencing of Arabidopsis thaliana small RNAs was conducted to reveal microRNAs (miRNAs) and other small RNAs that were differentially expressed in response to phosphate (Pi) deficiency. About 3.5 million sequence reads corresponding to 0.6-1.2 million unique sequence tags from each Pi-sufficie...
ORGANISM(S): Arabidopsis thaliana 
Gene expression is regulated both by cis elements, which are DNA segments closely linked to the genes they regulate, and by trans activating factors, which are usually proteins capable of diffusing to unlinked genes. Understanding the patterns and sources of regulatory variation is crucial for under...
