In agriculture, web-based social media are increasingly used to share knowledge concerning best practices. One goal of agroecology is to reduce the use of synthetic chemical inputs. Agroecology represents a contrast with intensive agriculture in that it better manages interactions with life forms. It is crucial to help people share their knowledge to accomplish the agroecological transition. This paper proposes an analogy between the use of social media to facilitate (1) caring for plants in the context of agroecology and (2) preventing human diseases in the context of medicine. The authors created a bibliography of scientific publications related to social media use in preventative medicine to identify best practices for social media use (and the associated drawbacks) that can be applied to develop social media dedicated to agroecology.

The parents and transgressive variation lines of hybrids with significant difference in amylose content were selected to compare and analyze the accumulation characteristics of amylose and the change of OsRSR1 expression in grains in the process of grain filling, and the PCR technology was used to clone the OsRSR1 gene base sequence of four varieties. The results showed that the amylose content in grains increased gradually with grain filling process, the amylose content of offspring and parents with high amylose content were higher than the offspring and parents with low amylose content, hybrids could obtain the transgressive variation lines through the continuous directional selection of amylose content in grain, and the accumulation of amylose content in grain was closely related to genotypes. The expression quantity of OsRSR1 gene in grain was increasing during the grain filling process, the amylose content of grain was closely related to the activity of OsRSR1 gene, and the expression of grain OsRSR1 gene could also produce transgressive variation.
