We found that the bimodal GC3 distribution is not a specific feature of grasses but an ancestral one of most monocot genomes.
In Arabidopsis, only one RBR gene has been found, and the presence of two distinct RBR genes have been suggested to a unique feature of grasses [ 59].
Two exceptions to this rule are the low overall SSR frequency of gymnosperm ESTs, which may be an intrinsic characteristic, and the abundance of the SSR trimer motif CGG/CCG, which seems to be a distinct feature of grasses.
Intraspecific local sequence comparisons have also identified interesting features of grass genome structure and evolution.
Some additional features of grass pollen morphology that also have taxonomic significance, such as the distribution of tectal columellae (Fægri et al., 1992; Beug, 2004; Holst et al., 2007), cannot be seen using the SEM because this instrument records information from the surface of individual specimens (Sivaguru et al., 2012).
A dozen years separated Kelly Reichardt's first feature, "River of Grass," from her second, "Old Joy," which quickly established her as one of the leading American independent filmmakers.
So did Kelly Reichardt, who after winning admirers in 1994 for her debut feature, "River of Grass," and then stalling out in Hollywood, returned in 2006 with "Old Joy," one of the high points of that festival.
Much like Ms. Reichardt's first feature, "River of Grass" (1995), about a young woman who dreams of escaping her dreary life by going on the lam, "Old Joy" briefly borrows the conventions of the road movie while keeping its romance safely at bay.
"He's really great at being able to not impose what he would do, but he can figure out your aesthetic and talk to you about it," said Kelly Reichardt ("Meek's Cutoff"), whose 1994 debut feature, "River of Grass," starred Mr. Fessenden.
