Background: The stem, which consists of nodes and internodes, is an axis of the shoot that physically supports lateral organs such…
Key factors that interactively regulate maize endosperm development
The Plant Cell: In a NutshellWu et al. explore how three key transcription factors co-regulate gene networks and the regulatory landscape associated with endosperm development and seed phenotype in maize.

Arabidopsis long non-coding RNAs: an orchestrated hubbub
The Plant Cell: In a NutshellKornienko et al. discover that Arabidopsis genome is full of long-non-coding RNAs that show their expression only in specific tissues and plants from different geographic origins because of differences in epigenetic silencing of these genes.

By Chunlei Zhou from Nanjing Agricultural University
Background: Grain size is a key factor for determining grain yield. Many genes or quantitative trait loci (QTLs) that regulate…
Review. Milestones in understanding phosphorus uptake, transport, sensing, use, and signaling
Plant Science Research WeeklyPhosphorus (P) is an essential nutrient and critical component of nucleic acids, phospholipids, and other molecules. Yang et al. provide a historical (since 1996) overview of the processes controlling its uptake and use. Plants take up P from the rhizosphere primarily in the form of orthophosphate (Pi).…
Review: CEP hormones at the nexus of nutrient acquisition and allocation, root development, and plant–microbe interactions
Plant Science Research WeeklyC-TERMINALLY ENCODED PEPTIDE (CEP) is a multigene family of peptide hormones originally described as systemic long-distance signals in response to nitrogen limitation. Over the years since the discovery of these peptide hormones, the literature on CEP biology has expanded the repertoire of developmental…
Review: Stem cells for crop improvement
Plant Science Research WeeklyPlants, like animals, have small populations of stem cells capable of differentiating into other tissues, but in plants these stem cell populations are even more long-lived and versatile. Stem cells in plants include the meristems (shoot and root apical meristems, inflorescence and axillary meristems)…
