| Summary: | F-box proteins containing variable C-terminal domains make an essential part of SKP1-Cullin-Ring box-F box (SCF) complex. SCF complex catalyzes the final step to link the ubiquitin tag with the target protein, destined for degradation, through F-box protein that confer overall substrate specificity to the complex. In this study, we analyzed the role of At2g02870, a Kelch containing F-box protein from Arabidopsis thaliana, by using reverse genetics strategy. At2g02870 loss of function mutant lines (at2g02870) were analyzed and compared with wild type plants for the expression of genes and products of hydroperoxide lyase (HPL) branch of oxylipin pathway. We found that the at2g02870 plants have enhanced expression of HPL pathway genes and produce more green leaf volatiles (GLV) than the wild type plants. Our results suggested that the gene is involved in the regulation of HPL pathway, possibly through the degradation of enzymes or/and the regulatory factors of the pathway.
