Antimicrobial peptides
Plants produce a high number of various antimicrobial peptides such as defensins, thionins, lipid transfer proteins and snakins. It had been recently found that these classes of genes account of approximately 2% – 3% of the gene repertoire of each model species (Egorov et al., 2005, Peptides 26, 2064 – 2073; Silverstein et al., 2007, Plant J. 51, 262 – 280; Rossi et al., 2008, J. Pharm. Sci. 97, 1060 – 1070).

Highlights in protein phosphorylation in chloroplasts
Two thylakoid protein kinases (STN7/Stt7) and (STN8/Stll) control the phosphorylation of light-harvesting antenna and photosystem II proteins (D1, D2, CP43, PsbH) (Bellafiore et al., 2005, Nature 433, 892 – 895; Bonardi et al., 2005, Nature 437, 1179 – 1182; Varionen et al., 2005, JBC 280, 33679 – 33686; Rochaix J-D, 2007; FEBS Lett. 581, 2768 - 2775).
STN8 is involved in the phosphorylation of the novel light-regulated phosphoprotein of thylakoid membranes, CaS (Vainonen et al., FEBS J, March 2008).

Small Cab-like proteins of cyanobacteria
Small Cab-like proteins (SCP or also known as HLI, high-light inducible polypeptides) were found to be associated with photosystem II of Synechocystis sp. PCC 6803 (Yao et al., 2007, JBC 282, 267 – 276; Kufryk et al., 2008, Photosynth. Res. 95, 135 – 145). These proteins are not involved in the stability of functional photosystem II but retard the degradation of photosystem II-associated chlorophyll (Vavilin et al., 2008, JBC 282, 37660 – 37668).
