Abstract
We identified an alternative mode of cytokinin action that uses endocytic trafficking as a means to direct plant organogenesis. This activity occurs downstream of known cytokinin receptors but through a branch of the cytokinin signaling pathway that does not involve transcriptional regulation. We sh...

Abstract
We discovered 16 drought stress-associated miRNA (DsAmR) families in P. patens through computational analysis. Due to the possible discrepancy of expression periods and tissue distributions between potential DsAmRs and their targeting genes, and the existence of false positive results in computation...

Abstract
We report here that the expression of endogenous microRNAs (miRNAs) can be efficiently silenced in Arabidopsis thaliana (Arabidopsis) using artificial miRNA (amiRNA) technology. We demonstrate that an amiRNA designed to target a mature miRNA directs silencing against all miRNA family members, wherea...

Abstract
Transient populations of cis- and trans-acting small RNAs have recently emerged as key regulators of extensive epigenetic changes taking place during periconception, which encompasses gametogenesis, fertilization, and early zygotic development. These small RNAs are not only important to maintain gen...

Paramutation refers to the process by which homologous DNA sequences communicate in trans to establish meiotically heritable expression states. Although mechanisms are unknown, current data are consistent with the hypothesis that the establishment and heritable transmission of specific chromatin sta...

Abstract
We show that in virus-infected plants the enhanced expression of AGO1 mRNA is not accompanied by increased AGO1 protein accumulation. We also show that the induction of AGO1 mRNA level is a part of the host defence reaction, whereas the induction of miR168, which overlaps spatially with virus-occupi...

Abstract
We recently performed a genome-wide survey for endogenous targets silenced by MOM1 and identified loci that are concentrated around centromeres and rich in sequences homologous to the 24-nt small interfering RNAs (siRNAs) that accumulate in wild type plants. Further and independent analyses indicate...

Abstract
MicroRNAs (miRNAs) are 21-23 nucleotide (nt) non-coding RNAs that play a key role in regulating the expression of protein-coding genes at post-transcriptional levels in plants and animals. MiRNA genes, which serve as genetic buffers and regulators, are primarily located in the intergenic regions of...

Abstract
We reinvestigated the relationship between auxin-induced elongation and gene expression of glucanases upon treatment of coleoptile segments with sugars. Gene expression of exo-beta-1,3:1,4-glucanase ExoII was not affected by treatment with IAA and/or sucrose. In contrast, levels of endo-beta-1,3:1,4...

Abstract
Plants have evolved a variety of gene silencing pathways mediated by small RNAs. Mostly 21 or 24 nt in size, these small RNAs repress the expression of sequence homologous genes at the transcriptional, post-transcriptional and translational levels. These pathways, also referred as RNA silencing path...
