Investigation of the molecular, physiological and genetic bases of the phosphate and zinc homeostasis crosstalk in Arabidopsis
To meet the global food demand agriculture expansion by 2050 will be accompanied by an approximate 2.5-fold increase in the nutrient input. In many developing tropical countries, subsistence farmers cannot buy enough fertilizer due to limited financial capacities or poor infrastructure.
To solve this problem, in the selected mobility project a comprehensive investigation of the molecular, physiological and genetic bases of the phosphate and zinc homeostasis crosstalk in Arabidopsis will be carried out. A knowledge database generated from the successful completion of this project will help to generate crop plants able to cope with ions deficiency and use available nutrients efficiently, reducing farmer dependence on fertilizer.
I hold a Masters in Botany with distinction majoring in plant physiology and biochemistry. During my PhD training, the expertise I acquired was in the area of molecular and physiological aspects of the crosstalk between plant hormones (brassinosteroids, auxins, abscisic acid) and polyamines under heavy metal stress tolerance. My PhD training provided me with external insights into the complexity of the crosstalks, which could be involved in the coordination of development according to plant hormones/nutrient (essential/non essential) cues. During my post-doctoral stint, I continued studying the physiological and molecular crosstalk of brassinosteroids with polyamines under heavy metal stress, and also studied the role of paclobutrazol in drought stress management in tomato using a combination of genomics, systems and bioinformatics approaches.
My immediate research plans include elucidation of the crosstalk between an essential macro- and micronutrient (essential heavy metal), namely phosphate and zinc, crosstalk in plants, is not only of great scientific interest, but also crucial for sustainable agriculture worldwide. I aim to facilitate the transfer of this knowledge to an agronomic or biotechnological application, such as producing crop plants that are able to grow on soil with low micronutrient concentration. Ultimately, my long term goal is to develop a research group of my own and continue to undertake research with high scientific impact, evidenced by the continued publication in high impact sources and uptake of outputs by industry to inform practice for greater global food security.
