Genome-wide identification and analysis of the NF-Y transcription factor family reveal its potential roles in tobacco ( L.).

Nuclear Factor Y (NF-Y) represents a group of transcription factors commonly present in higher eukaryotes, typically consisting of three subunits: NF-YA, NF-YB, and NF-YC. They play crucial roles in the embryonic development, photosynthesis, flowering, abiotic stress responses, and other essential processes in plants. To better understand the genome-wide NF-Y domain-containing proteins, the protein physicochemical properties, chromosomal localization, synteny, phylogenetic relationships, genomic structure, promoter -elements, and protein interaction network of NtNF-Ys in tobacco ( L.

Zygotic genome activation (ZGA) is crucial for maternal to zygotic transition at the 2-8-cell stage in order to overcome silencing of genes and enable transcription from the zygotic genome. In humans, ZGA is induced by DUX4, a pioneer factor that drives expression of downstream germline-specific genes and retroelements. Here we show that herpesviruses from all subfamilies, papillomaviruses and Merkel cell polyomavirus actively induce DUX4 expression to promote viral transcription and replication.

Signals from the lens regulate multiple aspects of eye development, including establishment of eye size, patterning of the presumptive iris and ciliary body in the anterior optic cup and migration and differentiation of neural crest cells. To advance understanding of the molecular mechanism by which the lens regulates eye development, we performed transcriptome profiling of embryonic chicken retinas after lens removal. Genes associated with nervous system development were upregulated in lens-removed eyes, but the presumptive ciliary body and iris region did not adopt a neural retina identity following lens removal.

The expression of maternal derived antibodies (MDAs) and avian β-defensins (AvBDs) in yolk sac tissue may be age-specific and influenced by breed, thereby immunological window difference in hatchlings. This study investigated the mRNA expression of MDAs and AvBDs in the yolk sac tissues of Beijing You and Hy-Line Gray chickens from the embryonic day (ED)7 to 3 days after hatch (DAH). Hy-Line showed a higher embryo bodyweight and a lower residual yolk weight at ED17 (P < 0.

Alternative proteins (AltProts) are a class of proteins encoded by DNA sequences previously classified as noncoding. Despite their historically being overlooked, recent studies have highlighted their widespread presence and distinctive biological roles. So far, direct detection of AltProt has been relying on data-dependent acquisition (DDA) mass spectrometry (MS).
