Article Abstract
Meiosis is a critical biological process for reproduction and genetic variation in higher plants. Gene duplication is a prominent feature of plant genomic architecture. Meiosis and gene duplication are of fundamental importance in unraveling the nature of genetics and evolution. The ideas and findings in this letter demonstrate a highly significant connection between meiosis and gene duplication, bring together these two disparate fields of study and highlight the importance of meiosis for understanding the evolutionary success of flowering plants. These insights and opinions open a new area of investigation and point to a significant way to illustrate the impact of duplicated genes on meiosis and fitness in higher plants, as well as their ultimate evolutionary, ecological, and agronomic impacts in light of challenges that have arisen due to global climate change. This study addresses novel ideas and viewpoints in plant developmental genomics and evolution.

Organismal complexity strongly correlates with the number of protein families and domains.

In the pregenomic era, scientists were puzzled by the observation that haploid genome size (the C-value) did not correlate well with organismal complexity. This phenomenon, called the "C-value paradox," is mostly explained by the fact that protein-coding genes occupy only a small fraction of eukaryotic genomes. When the first genome sequences became available, scientists were even more surprised by the fact that the number of genes (G-value) was also a poor predictor of complexity, which gave rise to the "G-value paradox.

Division of Pediatric Endocrinology, All India Institute of Medical Sciences, New Delhi, India.
Background: 46, XY disorders of sex development (DSD) are a group of highly heterogeneous conditions in which the molecular etiology remains unknown in a significant proportion of patients, even with massive parallel sequencing. Clinically significant copy number variants (CNVs) are identified in 20-30% of cases, particularly among those with gonadal dysgenesis (GD) and no molecular diagnosis.
Methods: Fourteen patients with 46, XY DSD due to GD in whom no pathogenic/likely pathogenic variants were found on next-generation sequencing using a targeted panel of 155 genes were screened for clinically significant CNVs using Affymetrix Comparative Genomic Hybridization (CGH).
Structural and evolutionary insights into the functioning of glycoprotein hormones and their receptors.

Department of Biochemistry and Molecular Biophysics, Columbia University, New York, New York, USA.
The neuroendocrine system that comprises the glycoprotein hormones (GpHs) and their receptors is essential for reproduction and metabolism. Each GpH hormone is an αβ heterodimer of cystine-knot proteins and its cognate receptor is a G-protein coupled receptor (GPCR) distinguished by a large leucine-rich-repeat (LRR) extracellular domain that binds the hormone and a class A GPCR transmembrane domain that signals through an associating heterotrimeric G protein. Hence, the receptors are called LRR-containing GPCRs-LGRs.

Laboratory of Artificial Intelligence Applied to Bioinformatics, Professional and Technical Education Sector - SEPT, UFPR, Curitiba, Paraná, Brazil.
Background: Diazotrophs carry out biological nitrogen fixation (BNF) using the nitrogenase enzyme complex (NEC), which relies on nitrogenase encoded by nif genes. Horizontal gene transfer (HGT) and gene duplications have created significant diversity among these genes, making it challenging to identify potential diazotrophs. Previous studies have established a minimal set of Nif proteins, known as the Nif core, which includes NifH, NifD, NifK, NifE, NifN, and NifB.

College of Horticulture, Bioinformatics Center, Academy for Advanced Interdisciplinary Studies, Nanjing Agricultural University, Nanjing, 210095, China.
The traditional Chinese medicinal plant Prunella vulgaris contains numerous triterpene saponin metabolites, notably ursolic and oleanolic acid saponins, which have significant pharmacological values. Despite their importance, the genes responsible for synthesizing these triterpene saponins in P. vulgaris remain unidentified.
