MicroRNAs and their regulatory roles in plants
Article Abstract:
MicroRNAs (miRNAs) are small, endogenous RNAs that regulate gene expression in plants and animals, where ~21 of these nucleotide RNAs in plants are processed from stem-loop regions of long primary transcripts by a Dicer-like enzyme and are loaded into silencing complexes, where they generally direct cleavage of complementary mRNAs. miRNAs play a crucial role at the cores of gene regulatory networks, targeting genes that are themselves regulators.

Mechanism of leaf-shape determination
Article Abstract:
Leaf-shape control mechanisms especially of Arabidopsis genes determined from a major genetic research project are discussed. 'Compensated cell enlargement', a curious phenomena found in leaf organogenesis may provide interesting details regarding the mechanisms of multicellular organ development.
