Abstract
Nitrate is a critical nutrient for plant growth, affecting biomass accumulation and development. This study explores the impact of nitrate supplementation on leaf growth in wild-type and mutant Arabidopsis thaliana to determine whether genetic differences influence nitrate response. Plants were grown under both control and nitrate-treated conditions, and leaf number was documented and measured.
Mutant plants exhibited lower leaf counts overall, even before nitrate treatment. After nitrate treatment, the quantity of leaves seemed to even out across the board, leading to no significant difference between the treated plants. These results suggest that without any nitrate, the mutants had fewer leaves than the wild type. However, with the addition of nitrate, both the wild types and the mutants shared similar numbers of leaves.
These findings highlight the role of genetic factors in nitrate metabolism and introduce the opportunity for future experiments regarding the interaction between growth and nitrate. This may inform future studies on improving nitrogen use efficiency in crops.
