Summary: Effective nitrogen management is crucial for optimizing crop growth and minimizing environmental impact. This study found that using calcium cyanamide as a slow-release nitrogen source improved onion growth and yield while reducing nitrogen leaching. Additionally, topdressing calcium cyanamide with limestone ammonium nitrate or urea further enhanced plant growth and total yield, and decreased onion bolting.

Summary: This paper introduces the onion production in Pakistan and the phenomenon of bolting in onion plants due to fluctuations in environmental factors. To reduce bolting, a Smart Farming Monitoring System (SFMS) is proposed to provide a more favorable environment using IoT technology and remote monitoring. In experiments, the SFMS successfully reduced the bolting rate, leading to better onion production.

Summary: Late-bolting Chinese cabbage lines were developed through mutagenesis of the BrLFY gene using the CRISPR/Cas9 system. The edited lines showed delayed bolting and continuous vegetative growth compared to the control line. This study demonstrates that CRISPR/Cas9-mediated mutagenesis is a useful method for molecular breeding of crops.

Summary: This study identified nine QTLs associated with radish flower color, bolting time, and flowering time, with three major QTLs qRFC1, qRBT1, and qRFT1 consistently explaining a high proportion of the variation. Candidate genes related to flower color and bolting/flowering times were annotated, providing valuable information for radish breeding programs and functional characterization. Genetic complexity of radish traits was revealed, with candidate genes in the QTL regions potentially being useful for future breeding efforts and functional studies.

Summary: Argonaute proteins CSR-1 and CSR-2 in Caenorhabditis elegans, interacting with 22G-RNAs, are found to be involved in the accurate formation of synaptonemal complexes during homolog recognition. CSR-1 associates with CeRep55 minisatellites, which express 22G-RNAs and lncRNAs that colocalize with synaptonemal complexes on paired chromosomes and cohesin regions of unpaired chromosomes. CSR-1 and CSR-2 play crucial roles in homology recognition and condensation of unpaired chromosomes through targeting repeat-derived lncRNAs.

Summary: Transplantation time had a greater impact on agronomic traits than physicochemical traits, but did not affect the percentage of early flowering in genotypes. The first transplantation season yielded higher bulb productivity, while the second season reduced the cycle and productivity.

Summary: This study identified key genes and genetic networks related to bolting in spinach through RNA-seq analysis, revealing their association with vernalization, photoperiod/circadian clock, gibberellin, autonomous, and aging pathways. The analysis also highlighted potential roles of genes like Fructose-1, 6-bisphosphate aldolase, TREHALOSE-6-PHOSPHATE SYNTHASE 1, FLOWERING PROMOTING FACTOR 1, EARLY FLOWERING, GIGANTEA, and MADS-box proteins in initiating or delaying bolting. The findings provide insights into bolting control and have implications for molecular breeding programs and further research on genetic mechanisms related to bolting in other vegetable crops.

Summary: This study reports an approach to greatly increase the binding energy of cation-pi interactions by replacing Trp in the aromatic box with an electron-rich Trp derivative. By using this approach, the binding affinity between histone H3K4me3 and its reader can be significantly enhanced, and a high-affinity H3K4me3 Super-Reader can be constructed.
