[[Ultraviolet#Subtypes|Ultraviolet-B radiation]] (UV-B) from sunlight stimulates plant growth, but in high amounts can increase production of tissue-damaging [[reactive oxygen species]] (ROS), i.e., [[oxidants]]. Using &#039;&#039;[[Arabidopsis thaliana]]&#039;&#039; (common name: thale cress), researchers demonstrated that UV-B exposure increased pyridoxine biosynthesis, but in a mutant variety, pyridoxine biosynthesis capacity was not [[Enzyme induction and inhibition|inducible]], and as a consequence, ROS levels, [[lipid peroxidation]], and cell proteins associated with tissue damage were all elevated.Biosynthesis of [[chlorophyll]] depends on aminolevulinic acid synthase, a PLP-dependent enzyme that uses [[succinyl-CoA]] and [[glycine]] to generate [[aminolevulinic acid]], a chlorophyll precursor. In addition, plant mutants with severely limited capacity to synthesize vitamin B&lt;sub&gt;6&lt;/sub&gt; have stunted root growth, because synthesis of [[plant hormone]]s such as [[auxin]] require the vitamin as an enzyme cofactor.</div>
