Novo artigo publicado na npj Science of Plants! 🌱🍅
É com grande entusiasmo que anunciamos a publicação do nosso artigo:
“Tomato aspartic proteinases harbouring PSI domains reveal stress responsiveness, organ specificity, and conserved features.”
Neste estudo, investigámos proteinases aspárticas contendo domínios PSI em Solanum lycopersicum (tomateiro), analisando as suas características moleculares, expressão específica por órgão e resposta a stress abiótico.
🔬 Identificámos 58 APs no tomateiro, das quais cinco possuem domínio PSI.
🌿 Observámos elevada expressão em cotilédones e raízes, com padrões específicos em tecidos reprodutivos.
🌊 Sob stress osmótico e salino, verificaram-se respostas diferenciadas, com aumento de marcadores de stress oxidativo e ativação de mecanismos antioxidantes.
Os nossos resultados destacam o papel regulatório destas enzimas na adaptação das plantas a condições ambientais adversas.
Parabéns a toda a equipa pelo excelente trabalho! 👏

We are excited to share our latest publication:
“Tomato aspartic proteinases harbouring PSI domains reveal stress responsiveness, organ specificity, and conserved features.”
In this study, we investigated PSI-containing aspartic proteinases in Solanum lycopersicum (tomato), focusing on their molecular characteristics, tissue-specific expression, and responses to abiotic stress.
🔬 We identified 58 APs in tomato, five of which contain a PSI domain.
🌿 Most PSI-containing APs are highly expressed in cotyledons and roots, with organ-specific patterns in reproductive tissues.
🌊 Under osmotic and saline stress, distinct expression patterns were observed, accompanied by increased oxidative stress markers and antioxidant responses.
Overall, our findings highlight the tightly regulated role of PSI-containing APs in plant adaptation to environmental stress.
Congratulations to the entire team on this achievement! 👏
