Lotus ( Nelumbo ) is one of the top ten flowers in China, which has high ornamental, edible and medicinal value. Lotus has a been cultivated for thousands of years. Through discovery and cultivation, more than 4,000 cultivars have been recorded. However, the information related to lotus breeding is quite scattered, and the related genetic rules and trait formation mechanisms are still poorly understood, which has caused a greater impact on lotus genetic breeding. This article systematically introduces lotus germplasm resources, including wild species and cultivated species, summarizes lotus breeding methods and breeding directions, and focuses on the latest progress in the isolation and functional identification of structural and regulatory genes related to important horticultural traits. Prospects for the protection and utilization of lotus resources, breeding and industrialization are reported.

Flower type is the most valuable ornamental trait in floricultural plants, for which the ABCDE model was proposed to explain the identity of each floral organ in flowering plants. The C-class gene AGAMOUS ( AG ) is responsible for stamen formation and plays an essential role in the double flower phenotype. A previous study in carnation revealed that the mutation in the miR172 binding site of the A-class gene APETALA2 ( AP2 ) leads to petal accumulation. And the expression level of AG was reduced significantly in the double flowers compared with that in the single flowers. However, there was no sequence polymorphism detected between AGs isolated from the double flowers and single flowers. Here, we performed AG analysis using single and semi-double flower carnations, and detected several mutations located in the crucial position like the MADS-box domain in the AGs of semi-double flower carnations while no changes were found at the miR172 binding site of AP2 . As a result, the expression levels of AGs are reduced in the semi-double flower carnation, which could be caught by the loss function of AGs . Our data proves that AGs mutations are also associated with the semi-double flower formation in carnation, complementing the lack of research about AG -mutation-associated double flower formation in carnation.

Melatonin regulates lily bulblet development; however, the key interactions have not yet been determined. In this study, we found that adding 20 µ M melatonin to the growth medium increased the bulblet circumference and the trehalose and starch content. Moreover, the expression of numerous genes involved in cell proliferation and carbohydrate accumulation were upregulated. Further analysis showed that melatonin downregulated the expression of LoRAV and upregulated the expression of LoBPM3 at an early stage. Cloning and bioinformatics analysis showed that LoRAV is 1056 bp in length and encodes a protein with two structural domains, namely, AP2 and B3; the encoded protein is localized to the nucleus and has no self-activation activity, and this protein interacts with LoBPM3. The expression of LoTCP4 and LoAMY was upregulated, while the expression of LoAGPase , LoCYCB2-1 , and LoPCNA was inhibited when LoRAV was transiently overexpressed. However, the trends in the expression of the genes mentioned above, except LoAGPase and LoAMY, were reversed when LoRAV -OE was treated with melatonin. Interestingly, the expression of LoRAV , LoTCP4 and LoAMY was inhibited, and the expression of LoCYCB2-1 was upregulated by transient overexpression of LoBPM3 , but the expression of LoBPM3 was not regulated by LoRAV overexpression. Based on these data, we suggest that melatonin promoted bulb development, which was partly associated with regulation of the LoBPM3-LoRAV module; thus, LoRAV negatively regulates cell proliferation of bulblets, and LoBPM3 is located upstream of LoRAV and attenuates its expression.
