The LdWRKY23-LdFUS3 module positively regulates embryo development in lily.

The LdWRKY23-LdFUS3 module is a positive regulator of lily embryo development, with LdFUS3 expression linked to embryo viability in hybrid crosses.

• Why it matters: Understanding the molecular mechanisms of embryo abortion in lily hybridization is crucial for improving breeding success and overcoming barriers to distant hybridization.
• What they did: Researchers conducted transcriptome analysis, gene silencing, and molecular assays to identify and verify the roles of LdFUS3 and LdWRKY23 in embryo development, focusing on their expression and regulatory interactions.
• The result: The study demonstrates that the LdWRKY23-LdFUS3 pathway promotes embryo development and viability, providing potential molecular targets to enhance hybridization efficiency in lily breeding.
