Abstract
Many of the proteins involved in meiotic recombination are conserved among eukaryotes, and here we discuss those recombination proteins that have been identified in plants. In addition, we summarize some of the differences in crossover regulation between plants and budding yeast (the primary model for molecular studies of recombination in eukaryotes). We also discuss factors that influence the distribution of crossovers including chromosome, chromatin and genomic structure. Different methods have been used for mapping recombination in plants including genetic linkage maps, cytogenetic maps (e.g., chiasmata and recombination nodules), and physical maps (DNA sequence and contigs). Progress has been made in integrating the different types of maps to provide a more complete understanding of genome structure and function in plants, including the control of meiotic recombination.

Deep learning in Single Cell Analysis
The field of biology is undergoing a revolution in our ability to study individual cells at the molecular level, and to integrate data from multiple sources and modalities. This has been made possible by advances in technologies for single-cell sequencing, multi-omics profiling, spatial transcriptomics, and high-throughput imaging, as well as ...read more
New insights on Pediatric Tumors and Associated Cancer Predisposition Syndromes
Because of the broad spectrum of children cancer susceptibility, the diagnosis of cancer risk syndromes in children is rarely used in direct cancer treatment. The field of pediatric cancer genetics and genomics will only continue to expand as a result of increasing use of genetic testing tools. It's possible that ...read more
