C3 cotyledons are followed by C4 leaves: intra-individual transcriptome analysis of Salsola soda (Chenopodiaceae).

ABSTRACT: Some species of Salsoleae (Chenopodiaceae) convert from C₃ photosynthesis during the seedling stage to the C₄ pathway in adult leaves. This unique developmental transition of photosynthetic pathways offers the exceptional opportunity to follow the development of the derived C₄ syndrome from the C₃ condition within individual plants, avoiding phylogenetic noise. Here we investigate Salsola soda, a little-studied species from tribe Salsoleae, using an ontogenetic approach. Anatomical sections, carbon isotope (δ¹³C) values, transcriptome analysis by means of mRNA sequencing, and protein levels of the key C₄ enzyme phosphoenolpyruvate carboxylase (PEPC) were examined from seed to adult plant stages. Despite a previous report, ou
