Activities of Synthetic Tob Sys I and II. Synthetic Tob Sys I and II lack carbohydrates, so Ala substitutions have been introduced at each position in the primary structure. The analogs were assayed by monitoring the change in pH in the medium at 15 min after supplying 25 nmol of the systemins to 1 mL of L. peruvianum cultured cells. Error bars indicate standard deviation from three experiments.

Tree Plot of the RALF Genes Present in Arabidopsis. Created by the program Pileup (Genetics Computer Group), this tree plot shows the clustering relationships among the different RALF-like genes found in the Arabidopsis genome. The identity (%) between the clones in each cluster, the clone accession number, and the tissue from which each EST is derived are shown.

Proteolytic Processing of the PSK-α. PSK-α is proteolyically processed from the C terminus of a preproprotein precursor. The precursor is synthesized through the secretory pathway where the signal sequence is removed, and where the sulfate groups are attached to tyrosine residues.

Model for the Receptor Complex and Its Interaction with the Polypeptide CLV3. A model for the receptor complex and its interaction with the polypeptide CLV3, which regulates the balance of cell proliferation and organ formation in the shoot and flower meristems of Arabidopsis. Upon binding of CLV3 to the CLV1-CLV2 receptor complex, the protein kinase domain becomes activated, leading to the autophosphorylation of CLV1 and subsequent signaling pathway events. (Adapted from Trotochaud et al., 1999.) s-s, disulfide bonds; P, phosphorylation.

SI Signaling in Brassica. Shown is a model for the initial steps of SI signaling in Brassica (Franklin-Tong and Franklin, 2000). When pollen grains come in contact with the papilla surface of the stigma, the polypeptide signal, SCR, interacts with the SLG-SRK receptor kinase complex to activate a signaling cascade that leads to the incompatible SI response. The complex results in the activation of the receptor kinase and the phosphorylation of ARCI, which may lead to the activation of aquaporins to limit the access of water to the incompatible pollen. P, phosphorylation.

Short ORFs Derived from the ENOD40 Genes from Alfalfa and Soybean. In soybean, a 12–amino acid polypeptide and a 24–amino acid polypeptide are translated from overlapping ORFs. aa, amino acids.
