Ensuring the future of perennial crops in Southeast Asia in a context of gobal change : case of Garcinia fruit tree species.

Abstract

Southeast Asian rainforests host a remarkable biodiversity. This natural heritage is seriously threatened from deforestation and climate change. To ensure that crop production meets future needs, genetic diversity (the source of adaptation and improvement) needs to be conserved in cultivated and in close wild relative species. Yet, determining wild ancestors of perennial crops is very complex. For a large number of cultivated plants, we still do not know their origin or cultivation history. These elements are fundamental to establish strategies of conservation, sustainable management and use (CSM&U) of perennial crops, and thus to ensure their contribution to food and nutrition security.

Goal

MANNGIS will focus on a key perennial crop, the mangosteen (Garcinia mangostana; Clusiaceae), as one of the most desirable tropical fruits of the region. Mangosteen’s place of origin and cultivation history remain unknown, but it is believed to have originated from a wild relative species in the Malay archipelago. Garcinia malaccensis and G. hombroniana are often cited as candidates, although this needs to be verified.

Action

WP 2. Effects of calcareous soil and high temperature on genome expression

Results

MANNGIS will allow:
unravelling the respective status of these species, as well as the cultivation history of mangosteen
identifying zones of high or particular genetic diversity to be conserved
contributing to the establishment of CSM&U strategies

Perspectives

Aa number of wild Garcinia species are still neglected (and threatened by deforestation), yet they can contribute to diversity in markets and to diets. These species need to be characterized (diversity, distribution, threats, nutrition, agronomic and economic potential, etc), and MANNGIS will provide a methodological framework to be replicated
