Abstract: The present application discloses a semi-dominant molecular marker related to maize dwarf and an application thereof, and relates to the technical field of maize molecular breeding. The molecular marker related to the maize dwarf is caused by a non-synonymous mutation from G to A in a maize gene Zm00001d013465, and the molecular marker is a nucleotide sequence composed of the non-synonymous mutation site and its upstream and downstream bases. The present application identifies a dwarf mutant, coded as E5779, from an EMS mutation population with maize B73 as the genetic background. By genome resequencing and Mutmap mapping, it is found that the mutant is caused by the non-synonymous mutation from G to A in the gene Zm00001d013465. The molecular marker is developed based on this, and the analysis and utilization of E5779 are helpful to improve the maize plant height and density-tolerant breeding, it has an important breeding application potential.

Abstract: An information display method, an information display apparatus, and an electronic device are provided. The information display method includes: acquiring a first interactive message card forwarded by a first terminal device, where the first interactive message card displayed by the first terminal device includes a data submission control element used to collect user data in response to an user interaction operation and send the collected user data to another electronic device; generating a second interactive message card based on the first interactive message card, where a data submission control element in the second interactive message card does not have a data collection function; and displaying the second interactive message card.
