Guard cell proteome - Dawn regulates guard cell proteins in Arabidopsis thaliana that function in ATP production from fatty acid beta-oxidation

Proteome changes that happen in the guard cells during dawn were up till now poorly described. Bad accessibility to pure and intact guard cell samples can be considered as the primary reason behind this lack of knowledge. By elucidating the identities of enzymes that change in abundance by the transition from dark to light, we corroborate the hypothesis that respiratory ATP production for stomatal opening results from fatty acid beta-oxidation.
