Identification and characterization of two APETALA2 homolog genes in lotus (Nelumbo nucifera) involved in sepal and petal development.

ABSTRACT:

Background

Lotus (Nelumbo nucifera) is a significant aquatic ornamental genus widely utilized in horticulture for its decorative, culinary, medicinal, and other practical uses. It presents a variety of flower shapes, including few-petalled, semi-double-petalled, double-petalled and thousand-petalled flowers, making it an ideal candidate for studying the flower development of aquatic plants. However, the molecular mechanism of floral development in lotus remains elusive.

Results

In this study, two APETALA2 (AP2) homologues, NnAP2a and NnAP2b, were identified in lotus. Interestingly, both NnAP2a and NnAP2b proteins contained two conserved AP2 domains and were verified to be located primarily in the nucleus. Both NnAP2a and NnAP2b showed high expression levels in the floral bud
