Generalized arterial calcification of infancy is a rare entity with poor fetal and postnatal outcomes and high morbidity in survivors. Half of the cases are diagnosed intrauterine due to hemodynamic compromise, and the associated manifestations pose unique management challenges. We hereby report an account of a fetal diagnosis in a referral for hydrops with postnatal evaluation and management.

Article Synopsis
  • Genomic imprinting occurs in the endosperm of plants, where specific gene expression is influenced by parental epigenetic marks on alleles.
  • A chromatin remodeler called OsCLSY3 is crucial for endosperm development and regulates small RNA pathways, showing a preference for paternal imprinting.
  • Disruption of OsCLSY3 leads to significant defects in endosperm development and a loss of small RNAs, highlighting its vital role in controlling imprinted and seed development-related genes in rice, with potential implications for other cereals.

Wounding is a general stress in plants that results from various pest and pathogenic infections in addition to environment-induced mechanical damages. Plants have sophisticated molecular mechanisms to recognize and respond to wounding, with those of monocots being distinct from dicots. Here, we show the involvement of two distinct categories of temporally separated, endogenously derived peptides, namely, plant elicitor peptides (PEPs) and phytosulfokine (PSK), mediating wound responses in rice.

Histones are crucial proteins that are involved in packaging the DNA as condensed chromatin inside the eukaryotic cell nucleus. Rather than being static packaging units, these molecules undergo drastic variations spatially and temporally to facilitate accessibility of DNA to replication, transcription as well as wide range of gene regulatory machineries. In addition, incorporation of paralogous variants of canonical histones in the chromatin is ascribed to specific functions.
