Beschreibung:
The development of plant root systems is sensitive to the availability and distribution of nutrients within the soil. For example, lateral roots proliferate preferentially within nitrate (NO3-)-rich soil patches. A NO3--inducible Arabidopsis gene (ANR1), was identified that encodes a member of the MADS box family of transcription factors. Transgenic plants in which ANR1 was repressed had an altered sensitivity to NO3- and no longer responded to NO3--rich zones by lateral root proliferation, indicating that ANR1 is a key determinant of developmental plasticity in Arabidopsis roots.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, H -- Forde, B G -- New York, N.Y. -- Science. 1998 Jan 16;279(5349):407-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biochemistry and Physiology Department, IACR-Rothamsted, Harpenden, Herts AL5 2JQ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9430595" target="_blank"〉PubMed〈/a〉
