To explore the molecular mechanisms of Ipomoea cairica invasiveness insouth China, the de novo transcriptomes from I. cairica and two related species, I. digitata and I. nil,were sequenced and assembled.There were5 6551 all-unigenes obtained by assembling the reads, among them 56522 all-unigenes were annotated, including 7815, 15615, and 180201 all-unigenes in GO, COG and KEGG databases, respectively. Moreover, the activities of NR and GS in I.cairica, keyenzyme in metabolic pathway for nitrogen, were greater than those in related species. In addition, the transcriptome data showed that the genes of key enzymes in secondary metabolism, such aspal, 4cl, cad, chs, and chi, had synergic differential expressionin I. cairica, I. digitata and I. nil. The production synthesis from metabolic pathway could play a key role in stress-resistant, growth and allelopathy of I. cairica. The RT-qPCR verification results of key genes were similar to those from transcriptome.Therefore, the result of the present research might explain partly the successful invasiveness of I. cairicain South China at the level of molecular biology.

Organ size is an important morphological trail in plants, and shows significant differences among species. Organ growth is influenced by environmental factors, such as light and nutrients; however, it is determined by the intrinsic information of cell number and cell size. A large number of genes involved in regulation of cell proliferation and/or cell expansion have been identified, and their up-regulated or down-regulated expression change organ size and accelerate organ growth by means of transcription regulation, protein synthesis and modification, hormonal regulation and cell-wall loosening, and so on. In spite of this, these genes act through relative independent pathways, making it difficult to demonstrate an integrated regulation network in plants. Further challenges will be the regulation pattern and molecular changes in different plant species. Several genes participated in organ growth have been used in crop breeding, and produced significantly large crops. Similarly, characterization of the genes involved in organ size control of Chinese herbs to artificially promote organ size and morphology at the molecular level will contribute to overcome the shortage and endangerment of medicinal plants.
