| Abstract: | Nitrogen (N) availability is one of the most important factors regulating plant metabolism and growth as it affects global gene expression profiles. Dynamic changes in chromatin structure, including histone modifications and nucleosome assembly/disassembly, have been extensively shown to regulate gene expression under various environmental stresses in plants. However, the involvement of chromatin related changes in plant nutrient responses has been demonstrated only in a few studies to date. In this study, we investigated the function of histone chaperone NUCLEOSOME ASSEMBLY PROTEIN1 (NAP1) proteins under N deficient conditions in Arabidopsis. In the nap1;1 nap1;2 nap1;3 triple mutant (m123-1), the expression of N-responsive marker genes and growth of lateral roots were decreased under N deficient conditions. In addition, the m123-1 plants showed a delay in N deficiency-induced leaf senescence. Taken together, these results suggest that NAP1s affect plant growth under N deficient conditions in Arabidopsis. |
