TL;DR: It is reported that carpel specification in the Oryza sativa (rice) flower is regulated by the floral homeotic gene DROOPING LEAF (DL) that is distinct from the well-known ABC genes.

TL;DR: A model of stamen and carpel specification in rice is postulate, with DL as a novel gene controlling carpel identity and acting mutually and antagonistically to the class B gene, SPW1.

TL;DR: The results suggest that the two C-class genes in rice have been partially subfunctionalized during rice evolution (i.e., the functions regulated by AG have be partially partitioned into two paralogous genes, OSMADS3 andOSMADS58, which were produced by a recent gene duplication event in plant evolution).

TL;DR: A new class of MITE is described, called miniature Ping (mPing), in the genome of Oryza sativa (rice), where mPing elements are activated in cells derived from anther culture, where they are excised efficiently from original sites and reinserted into new loci.

TL;DR: The FON1 gene was isolated by positional cloning and found that it encodes a leucine-rich repeat receptor-like kinase most similar to CLAVATA1 (CLV1) in Arabidopsis thaliana, which suggests that a pathway similar to the CLV signaling system that regulates meristem maintenance inArabidopsis is conserved in the grass family.
