• Molecular formula of hexose

• In this study, we built a yeast strain that produces the sucrose invertase Suc2p upon illumination with light and tested the population growth dynamics and the benefits of cooperation in various artificially shaped landscapes of cooperators and cheaters. The OptoSuc2 strain indeed acts as a cooperating cell when illuminated but remains a cheater when kept in the dark because non-illuminated cells cannot metabolize sucrose and instead rely on the hexose produced by adjacent cooperating cells. We were, therefore, able to quantitatively explore the spatial metabolic interactions between cooperators and cheaters.

• AtSWEET4 coding sequence was cloned into vector pDR196, the resulting construct was introduced into yeast hexose transport mutant EBY.VW4000 strain41. The yeast transformants were first grown on selective synthetic complete medium (without uracil) with 2% maltose as the sole carbon source. Drop tests were used to assess the growth of transformed yeast in 2% glucose and 1% fructose solid SD media with a serial of dilutions (OD500 = 1, 10−1, 10−2, 10−3, 10−4). The transformants with empty vector was used as a negative control. All transformants were grown at 30 °C for 3 days.
