An RNAi construct expressing a wPDS cDNA fragment induces photobleaching in hexaploid wheat. The PDS-RNAi transgenic T₀ lines were arranged based on the severity of photobleaching. A, Strong photobleached phenotype resulting in albino plants and lethality. B, Intermediate phenotype with patterns of streaks where photobleaching is affecting one-half of the leaf surface. C, Intermediate phenotype with patterns of streaks where photobleaching is affecting the central part of the leaves with the margins still green. D, Weak phenotype where only a small sector of the leaves is affected by photobleaching.
