Fecha de publicación: 17/10/2017 Fuente: Wipo tomato The invention provides a tomato SLLCD coding region gene, and tomato SLLCD protein encoded by the gene; a tomato coding region nucleotide sequence of the tomato SLLCD gene is shown as in SEQ ID No. 1. The tomato SLLCD gene and the application thereof have the advantages that the tomato LSSCD coding region gene is an enzyme coding gene related directly to the production of endogenous H2S, can inhibit SLLCD gene expression in tomato to significantly affect the development of seeds in tomato, and transgenic plants having zero seeds or incompletely developed seeds; the gene is applicable to the acquisition of seedless tomato and maintenance of beneficial matters in fruits; in addition, growth of fruits on SLLCD-transgenic plants is not affected; therefore, good traits of tomato can be maintained; it is indicated that the SLLCD gene is well applicable in the development process.
