Phosphoserine and phosphohydroxypyruvic Acid: evidence for their role as early intermediates in photosynthesis.

abstract：:Plant reproduction depends on the concerted activation of many genes to ensure correct communication between pollen and pistil. Here, we queried the whole transcriptome of Arabidopsis (Arabidopsis thaliana) in order to identify genes with specific reproductive functions. We used the Affymetrix ATH1 whole genome array ...
