Seminars at the Chair

António Miguel Frederico, Curso de Doutoramento em Ciências Agrárias, will be presenting a seminar on "AOX2a as source of potential functional markers for Daucus efficient somatic embryogenesis" in the frame of ICAAM PhD Seminar Series. More in here .

The stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals the termination of translation. Premature stop codons (premature termination of transcription) occurs when a mutation in which one of the three terminator codons in the mRNA used to signal the end of a polypeptide appears in the middle of a genetic message (nonsense mutation). Two genetically-encoded amino acids, selenocysteine and pyrrolysine, are encoded by what normally would be a stop codon – mechanism called translational recoding and depends on the presence of different compounds and translation initiation factors. Premature stop codons interfere with gene regulation, and can result in phenotypic consequences. Though often associated with diseases, they can give rise to interesting agronomic characteristics.

Strigolactones are multifunctional molecules involved in several processes outside and within the plant. As signalling molecules in the rhizosphere, they favour arbuscular mycorrhizal (AM) symbiosis establishment, but they also act as host detection cues for root parasitic plants.

This work aims at the analysis of the most stable proteins present in a thermophilic proteome(“stabilome”). The results obtained focus at identifying particularly stable proteins, cellular pathways or processes. A proteome-level perspective of protein stability in the cellular context contribute to a better understanding of functioning and control of proteins in biological systems.
