Hormones regulate the flowering process in saffron differently depending on the developmental stage
Frontiers in Plant Science, 2023 Flowering in saffron is a highly complex process regulated by the synchronized action of environmental cues and endogenous signals. Hormonal regulation of flowering is a very important process controlling flowering in several plants, but it has not been ...

NK2 homeobox gene cluster: Functions and roles in human diseases
Genes and Diseases, 2023 NK2 genes (NKX2 gene cluster in humans) encode for homeodomain-containing transcription factors that are conserved along the phylogeny. According to the most detailed classifications, vertebrate NKX2 genes are classified into two distinct families, NK2.1

Agrobacterium-mediated transformation of tomato elicits unexpected flower phenotypes with similar gene expression profiles. [PDF]
PLoS ONE, 2008 BACKGROUND: Genetic transformation mediated by Agrobacterium tumefaciens is known to cause unexpected phenotypes. Mutations of a specific set of homeotic genes can result in altered floral structure.

Chromatin folding by the Polycomb group proteins and its elusive role in epigenetic repression. [PDF]
FEBS JGenes repressed by the Polycomb system display greater chromatin folding compared to ‘regular’ inactive genes. The associated chromatin compaction, driven by PRC1‐H3K27me3 interactions, is modest and dynamic. This questions traditional models where Polycomb proteins repress transcription by sheltering genes from transcriptional activators.

Hyperconserved Elements in Human 5′UTRs Shape Essential Post-transcriptional Regulatory Networks
Frontiers in Molecular Biosciences, 2020 Post-transcriptional regulation (PTR) of gene expression is a powerful determinant of cellular phenotypes. The 5′ and 3′ untranslated regions of the mRNA (UTRs) mediate this role through sequence and secondary structure elements bound by RNA-binding ...

In planta localisation patterns of MADS domain proteins during floral development in Arabidopsis thaliana [PDF]
, 2009 Background: MADS domain transcription factors play important roles in various developmental processes in flowering plants. Members of this family play a prominent role in the transition to flowering and the specification of floral organ identity. Several
