The word is a hybrid construction derived from the Latin 'gravitas' (weight or heaviness) and the Greek 'tropos' (a turning or change in direction).

In the news

In the article, the term explains the biological mechanism being researched in pomegranate roots to help scientists understand how to breed more stable, deep-rooted crops. It is central to the field of plant biology as it determines how vegetation establishes itself in different environments.
