TLDR
An analysis of 715 Arabidopsis thaliana sequences from SWISS‐PROT suggests that the ChloroP method should be useful for the identification of putative transit peptides in genome‐wide sequence data.Abstract:
We present a neural network based method (ChloroP) for identifying chloroplast transit peptides and their cleavage sites. Using cross-validation, 88% of the sequences in our homology reduced training set were correctly classified as transit peptides or nontransit peptides. This performance level is well above that of the publicly available chloroplast localization predictor PSORT. Cleavage sites are predicted using a scoring matrix derived by an automatic motif-finding algorithm. Approximately 60% of the known cleavage sites in our sequence collection were predicted to within +/-2 residues from the cleavage sites given in SWISS-PROT. An analysis of 715 Arabidopsis thaliana sequences from SWISS-PROT suggests that the ChloroP method should be useful for the identification of putative transit peptides in genome-wide sequence data. The ChloroP predictor is available as a web-server at http://www.cbs.dtu.dk/services/ChloroP/.read more

Towards an understanding of wheat chloroplasts: a methodical investigation of thylakoid proteome
TL;DR: The chloroplast proteome contains many proteins that are localized to the thylakoids but as yet have no known function, and it is proposed that some of these familiar proteins participate in the photosynthetic pathway.

Identification and characterization of the Non-race specific Disease Resistance 1 (NDR1) orthologous protein in coffee
Jean-Luc Cacas,Jean-Luc Cacas,Anne-Sophie Petitot,Louis Bernier,Joan Estevan,Geneviève Conejero,Sébastien Mongrand,Diana Fernandez +7 more
TL;DR: The coffee NDR1 gene is isolated and characterized, whose Arabidopsis ortholog is a well-known master regulator of the hypersensitive response that is dependent on coiled-coil type R-proteins, and the cDNA was dubbed CaNDR1a (standing for Coffea arabica Non-race specific Disease Resistance 1a).

PgLOX6 encoding a lipoxygenase contributes to jasmonic acid biosynthesis and ginsenoside production in Panax ginseng
Shadi Rahimi,Shadi Rahimi,Yu-Jin Kim,Johan Sukweenadhi,Dabing Zhang,Dabing Zhang,Deok-Chun Yang +6 more
TL;DR: PgLOX6 encodes a lipoxygenase that is required for biosynthesis of jasmonic acid and its overexpression increases ginsenoside levels in ginseng.

Isolation of a polyphenol oxidase (PPO) cDNA from artichoke and expression analysis in wounded artichoke heads
TL;DR: expression analysis of the gene in wounded capitula indicated that CsPPO was significantly induced after 48 h, even though the browning process had started earlier, suggesting that the early browning event observed in artichoke heads was not directly related to de novo mRNA synthesis.

Identification of prokaryotic and eukaryotic signal peptides and prediction of their cleavage sites.
TL;DR: A new method for the identification of signal peptides and their cleavage sites based on neural networks trained on separate sets of prokaryotic and eukaryotic sequence that performs significantly better than previous prediction schemes and can easily be applied on genome-wide data sets.
SHORT COMMUNICATION Identification of prokaryotic and eukaryotic signal peptides and prediction of their cleavage sites
TL;DR: In this paper, a new method for the identification of in performance compared with the weight matrix method signal peptides and their cleavage sites based on neural (Arrigo et al., 1991; Ladunga et al, 1991; Schneider and networks trained on separate sets of prokaryotic and eukaryotic sequence.
