Roots are important to plants for a wide variety of processes, including nutrient and water uptake, anchoring and mechanical support, storage functions, and as the major interface between the plant and various biotic and abiotic factors in the soil environment. Understanding the development and architecture of roots holds potential for the exploitation and manipulation of root characteristics to both increase food plant yield and optimize agricultural land use. This theme issue highlights the importance of investigating specific aspects of root architecture in both the model plant Arabidopsis thaliana and (cereal) crops, presents novel insights into elements that are currently hardly addressed and provides new tools and technologies to study various aspects of root system architecture. This introduction gives a broad overview of the importance of the root system and provides a snapshot of the molecular control mechanisms associated with root branching and responses to the environment in A. thaliana and cereal crops.

“…We screened out the SSGs and GSGs expressed merely at the larva and adult stages to examine their presumed protein functions using InterProScan 5. The resulting analysis showing that signal-peptide domains prevail among SSGs and GSGs indicates that these LSGs may be of great importance in cell differentiation, as signal peptides have central roles in development [30]. InterProScan results for the predicted functions are provided in Additional File 5.…”

With the rapid growth of sequencing technology, a number of genomes and transcriptomes of various species have been sequenced, contributing to the study of lineage-specific genes (LSGs). We identified two sets of LSGs using BLAST: one included Caenorhabditis elegans species-specific genes (1423, SSGs), and the other consisted of Caenorhabditis genus-specific genes (4539, GSGs). The subsequent characterization and analysis of the SSGs and GSGs showed that they have significant differences in evolution and that most LSGs were generated by gene duplication and integration of transposable elements (TEs). We then performed temporal expression profiling and protein function prediction and observed that many SSGs and GSGs are expressed and that genes involved with sex determination, specific stress, immune response, and morphogenesis are over-represented, suggesting that these specific genes may be related to the Caenorhabditis nematodes' special ability to survive in severe and extreme environments.

“…As a result, the contribution of small open reading frames (sORF) to the development and response to abiotic and biotic stresses has not been investigated in much detail. 9,10 Greater than 8,000 sORFs have been reported in Arabidopsis 11,12 and many of these have been reported to be associated with morphogenesis. 12 Although some of the sORFs are present as antisense to the Arabidopsis Genome Initiative (AGI)-annotated genes (4.78%), the majority of these sORFs lie in intergenic regions.…”

“…Although the exact function of the peptides putatively encoded by these sORFs remains unclear, it is plausible that some are involved in root to shoot signaling in response to drought stress. Cell-to-cell and root-to-shoot signaling is extremely important in plants and both function to regulate developmental changes 10 and the response to abiotic stresses. Secreted peptides are reported to play an important role in cell-to-cell communication and are believed to coordinate and specify cellular functions in plants during development and the response to environmental stresses.…”
