Iriawati finished her PhD in 1996 at Nagoya University (Japan) which focus on plant morphogenesis. Since then, she has done some research and still maintains her focus in plant developmental biology, plant cell, organ and tissue culture, and plant improvement through polyploidization.
The research is focused on wide array of plants ranging from annual crops, horticulture, ornamental plants to treesRead more...
Through protoplast fusion, two distinct species of plants are fused together to form a new hybrid plant with the characteristics of both.Read more...
Plant improvement through polyploidization
Polyploid plants can arise spontaneously in nature by several mechanisms, including meiotic or mitotic failures, and fusion of unreduced (2n) gametes. Both autopolyploids and allopolyploids can be found among both wild and domesticated plant species.Most polyploids display novel variation or morphologies relative to their parental species. The mechanisms leading to novel variation in newly formed allopolyploids may include gene dosage effects (resulting from more numerous copies of genome content), the reunion of divergent gene regulatory hierarchies, chromosomal rearrangements, and epigenetic remodeling, all of which affect gene content and/or expression levelsRead more...
Formation of artificial agarwood
Naturally synthesized agarwood requires a lengthy process of up to thirty years, which impede its continuous production. Therefore, recent effort has been allocated to the elucidation of agarwood formation to stimulate its process rapidly. In this study, we artificially induced agarwood formation by injection and inoculation of cultivated Aquilaria malaccensis with strains of Fusarium solani isolated from different places in Indonesia.
Parts of the project has been published in:

Agroinfiltration of potato
Visi is working on establishment of hairy root lines and analysis of secondary metabolite production in the medicinal plant Talinum paniculatum (Javanese ginseng)
Isqim experiment is focused on the effect of heat shock on pollen development in chili peppers (Capsicum annuum)
In vitro tissue culture techniques offers a feasible alternative to improve the efficiency of agarwood oil production as well as to facilitate some in vitro experiments such as genetic transformation and investigation of the gene expression in agarwood biosynthesis.
