Compared with the prior art, the planting method for improving the content of the total flavone in the pueraria lobata has the advantages that the seedling bed soil in the seedling stage and the management in the planting stage are adjusted appropriately, the nutritional growth and leaf development can be effectively promoted, and the planting method is helpful for the synthesis of flavone; compared with an existing planting technology, the content of the total flavone in the pueraria lobata can be improved while the yield is ensured, thereby conforming to the stipulation of the Chinese pharmacopoeia.

Moso bamboo leaf shape regulation gene PheLBD29 and application thereof
The invention discloses a moso bamboo leaf shape regulation and control gene PheLBD29 and application thereof. The moso bamboo leaf shape regulation and control gene PheLBD29 has a nucleotide sequence as shown in SEQ ID NO. 1. The invention provides the moso bamboo PheLBD29 gene related to regulation and control of the leaf shape as well as the encoded protein and application thereof for the first time. The PheLBD29 gene overexpression vector is transferred into wild type arabidopsis thaliana through an agrobacterium tumefaciens mediated inflorescence dip dyeing method, and the result shows that compared with a wild type strain, the leaf shape of an overexpression strain is obviously changed. The result provides a theoretical basis for research on moso bamboo leaf development.
