Gene regulatory network (GRN) comprises complicated yet intertwined gene-regulator relationships. Understanding the GRN dynamics will unravel the complexity behind the observed gene expressions. Insect gene regulation is often complicated due to their complex life cycles and diverse ecological adaptations. The main interest of this review is to have an update on the current mathematical modelling methods of GRNs to explain insect science. Several popular GRN architecture models are discussed, together with examples of applications in insect science. In the last part of this review, each model is compared from different aspects, including network scalability, computation complexity, robustness to noise and biological relevancy.

B-box proteins (BBX) play pivotal roles in the regulation of numerous growth and developmental processes in plants, particularly the light-mediated biosynthesis of pigments. To elucidate the role of BBX transcription factors in the anthocyanin biosynthetic pathway of Lagerstroemia indica leaves, this study identified 41 BBX genes in the L. indica genome.

R-loops, three-stranded nucleic acid structures composed of RNA-DNA hybrids, are increasingly recognized as central regulators of genomic stability and transcription. These structures play critical roles across various cellular processes, including DNA replication, repair, and gene regulation, with significant implications for stem cell biology and disease pathogenesis. This review comprehensively explores the molecular underpinnings of R-loop formation, emphasizing the dual nature of R-loops in both facilitating normal cellular functions and contributing to genomic instability.

A new gene coding for an iron-containing enzyme was identified in the genome of Acinetobacter radioresistens. Bioinformatics analysis allowed the assignment of the protein to DyP peroxidases, due to the presence of conserved residues involved in heme binding and catalysis. Moreover, Ar-DyP is located in an operon coding also for other enzymes involved in iron uptake and regulation.

Troponin C (TnC) is a calcium-binding subunit of the troponin complex that regulates muscle contraction in animals. However, the physiological roles of TnC, especially in insect development and reproduction, remain largely unknown. We identified seven TnC genes encoding four EF-hand motif protein in the rice pest, the brown planthopper Nilaparvata lugens.
