Plant cells accumulate small RNA molecules that regulate plant development, genome
stability, and environmental responses. These small RNAs fall into three major classes …

The establishment, maintenance, and removal of epigenetic modifications provide an
additional layer of regulation, beyond genetically encoded factors, by which plants can …

Reproductive tissues are a rich source of small RNAs, including several classes of short
interfering (si) RNAs that are restricted to this stage of development. In addition to RNA …

Whereas micro (mi) RNAs are considered the clean, noble side of the small RNA world,
small interfering (si) RNAs are often seen as a noisy set of molecules whose barbarian …

Phased small interfering RNAs (phasiRNAs) are abundantly expressed in anthers and
linked to environment-related male fertility in grasses, yet how they function under different …

Anthers express the most genes of any plant organ, and their development involves
sequential redifferentiation of many cell types to perform distinctive roles from inception …

DNA methylation plays essential homeostatic functions in eukaryotic genomes. In animals,
DNA methylation is also developmentally regulated and, in turn, regulates development. In …

Male sterility is classified as either cytoplasmic male sterility (CMS) or genic male sterility
(GMS). Generally, CMS involves mitochondrial genomes interacting with the nuclear …

Successful pollen formation is essential for plant reproduction. During anther development,
microspore mother cells undergo meiosis to form tetrads. After being released from the …

Argonaute protein (AGO) in association with small RNAs is the core machinery of RNA
silencing, an essential mechanism for precise development and defense against pathogens …
