Gene Details:

• Gene ID: Zm00001eb375490
• Gene Symbol: ZmRNRL1 rnrl1
• Gene Name: ribonucleotide reductase large subunit1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• First, ZmRNRL1 and ZmRNRL2 are expressed ubiquitously; second, ZmRNRL2 is expressed at a lower level than ZmRNRL1; and third, ZmRNRL1 and ZmRNRL2 are expressed at higher levels in developing tissues compared to mature tissues.
• Both results suggest that ZmRNRL1 and ZmRNRL2 expression is sensitive to restrictive temperatures. However, we believed that reduced expression levels of ZmRNRL1 and ZmRNRL2 is not the major factor leading to the no-tassel phenotype of tvt1-R mutants at restrictive temperatures.
• ZmRNRL2 and ZmRNRL1 proteins have same interaction partners at normal growth temperatures. These results indicate that ZmRNRL2 performs molecular functions similar to ZmRNRL1, although they are expressed at different levels.
• ZmRNRL2 mutant has a thermosensitive vanishing tassel phenotype,mutant results in loss of subsidiary cells.
