Method & Evidence

AimTo identify and confirm genes responsible for zinc hyperaccumulation in Thlaspi caerulescens and to develop a transformation protocol for functional gene testing.
MethodMolecular biology techniques including microarrays, qPCR, RNA interference (RNAi), and plant transformation attempts.
ProcedureMicroarray analysis was used to identify differentially expressed genes in Thlaspi caerulescens compared to a non-accumulating relative. Candidate genes, such as HMA4, were selected and confirmed using qPCR. An RNAi construct was created to silence the HMA4 gene, and attempts were made to transform Thlaspi caerulescens using tissue culture and floral dip methods.
ContextEnvironmental remediation, agricultural land restoration, plant biotechnology.

Variables

IVPresence of HMA4 gene (or its expression level).
DVZinc accumulation levels in Thlaspi caerulescens.
CVPlant species (T. caerulescens vs. T. avense), soil type, environmental conditions (light, water, temperature).
