Arabidopsis Signal Responsive 1 (AtSR1) is involved in plant immune response as well as growth and development. (a) Phenotypic comparison. Five-week-old wild-type (WT) and the atsr1 loss-of-function plants were grown at 20–22 °C under a 12 h photoperiod. Scale bar represents 10 mm. (b) Growth comparison. Fresh weight of rosettes was calculated from five-week-old WT and the atsr1 loss-of function mutant were grown at 20–22 °C under a 12 h photoperiod. Values are means ±SD (n = 5). (c) Disease resistance test for WT and atsr1. Rosette leaves of five-week-old Arabidopsis were infiltrated with Pst DC3000 (OD₆₀₀ = 0.001), and the number of colony-forming units (cfu) was calculated at zero (1 h after inoculation) and three days post-inoculation (dpi). Values are means ± SD (n = 5).
