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/.

tasselseed1 is a lipoxygenase affecting jasmonic acid signaling in sex determination of maize.

TL;DR: Application of jasmonic acid to developing inflorescence rescued stamen development in mutant ts1 and ts2 inflorescences, revealing a role for jasMonic acid in male flower development in maize.

PIC1, an ancient permease in Arabidopsis chloroplasts, mediates iron transport.

TL;DR: Observations suggest that PIC1 functions in iron transport across the inner envelope of chloroplasts and hence in cellular metal homeostasis.

The Tomato Terpene Synthase Gene Family

TL;DR: In this paper, it was shown that the tomato genome contains 44 terpene synthase (TPS) genes, including 29 that are functional or potentially functional in at least some organs or tissues of the plant.

Jasmonate biosynthesis and the allene oxide cyclase family of Arabidopsis thaliana.

TL;DR: Immunohistochemical analyses and metabolic profiling data suggest regulation of JA biosynthesis by OPDA compartmentalization and a positive feedback by JA during leaf development and preferential activity of the AOS branch within the LOX pathway.

A chloroplast DegP2 protease performs the primary cleavage of the photodamaged D1 protein in plant photosystem II

TL;DR: The isolation of a single‐copy nuclear gene from Arabidopsis thaliana is reported, encoding a protease that performs GTP‐dependent primary cleavage of the photodamaged D1 protein and hence catalysing the key step in the repair cycle in plants.

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.
