TL;DR: These findings reveal that plants use a highly dynamic maternal ‘short-term stress memory’ with which to respond to adverse external conditions and epigenetically targeted sequences function as distantly-acting control elements of antisense long non-coding RNAs, which in turn regulate targeted gene expression in response to stress.

TL;DR: The effects of exogenous Se supply on physiological and biochemical processes that may influence yield and quality of maize under drought stress conditions are reported and Se may be an activator of particular classes of genes that are involved in tolerance to abiotic stresses.

TL;DR: It is proposed that, in nucellar cells of apomictic genotypes, PpSERK is the switch that channels embryo sac development and that it may also redirect signaling gene products to compartments other than their typical ones.

TL;DR: It is found that salinity could induce genome-wide changes in DNA methylation status, and that these changes, when averaged across different genotypes and developmental stages, accounted for 16.8% of the total site-specific methylation differences in the rapeseed genome, as detected by MSAP analysis.

TL;DR: In Poa pratensis the cDNA-AFLP method of mRNA profiling allowed us to visualize a total of 2248 transcript-derived fragments and to isolate 179 sequences that differed qualitatively or quantitatively between apomictic and sexual genotypes at the time of flowering when the primary stages of apomixis occur.
