Neurodevelopmental disorders (NDDs) encompass a group of conditions that impact brain development and function, exhibiting significant genetic and clinical heterogeneity. NAA15, the auxiliary subunit of the N-terminal acetyltransferase complex, has garnered attention due to its association with NDDs. However, the precise role of NAA15 in cortical development and its contribution to NDDs remain elusive.

Genetic information is involved in the gradual emergence of cortical areas since the neural tube begins to form, shaping the heterogeneous functions of neural circuits in the human brain. Informed by invasive tract-tracing measurements, the cortex exhibits marked interareal variation in connectivity profiles, revealing the heterogeneity across cortical areas. However, it remains unclear about the organizing principles possibly shared by genetics and cortical wiring to manifest the spatial heterogeneity across cortex.

Significant effort has been spent attempting to unravel the causal relationship between histone post-translational modifications and fundamental DNA processes, including transcription, replication, and repair. However, less attention has been paid to understanding the reciprocal influence-that is, how DNA processes, in turn, shape the distribution and patterns of histone modifications and how these changes convey information, both temporally and spatially, from one process to another. Here, we review how histone modifications underpin the widespread bidirectional crosstalk between different DNA processes, which allow seemingly distinct phenomena to operate as a unified whole.

Pinus pinaster Aiton (maritime pine) stands are suffering a generalized deterioration due to different decline episodes throughout all its distribution area. It is well known that external disturbances can alter the plant associated microbiota and metabolome, which ultimately can entail the disruption of the normal growth of the hosts. Notwithstanding, very little is known about the shifts in the microbiota and the metabolome in pine trees affected by decline.

The study of mutational processes in somatic genomes has gained recent momentum, uncovering a wide array of endogenous and exogenous factors associated with somatic changes. However, the overall landscape of mutational processes in germline mutations across the tree of life and associated evolutionary driving forces are rather unclear. In this study, we analyzed mutational processes in single-stranded RNA (ssRNA) viruses which are known to jump between different hosts with divergent exogenous environments.
