Lysobacter capsici AZ78, isolated from tobacco rhizosphere, effectively controls Phytophthora infestans and Plasmopara viticola on tomato and grapevine plants, respectively. We report the first draft genome sequence of the L. capsici species.

Cuticular membranes were isolated enzymically from tomato fruits and from the dorsal and ventral surfaces of the leaves of Euonymus japonicus. Penetration of Fe from FeSO(4) and FeEDDHA (ferric ethylenediamine di(o-hydroxyphenylacetate) in the absence and presence of urea through the isolated cuticular membranes was studied. Fe from FeSO(4) penetrated more rapidly through the cuticles than Fe f...

Delftia acidovorans strain HK171, isolated from tomato roots, exhibited nematicidal activity against Meloidogyne incognita Here, we present the genome sequence of D. acidovorans strain HK171, which consists of one circular chromosome of 6,430,384 bp, with 66.9% G+C content.

Ethylene is a plant hormone that has an essential role in fruit ripening (Yang and Hoffman, 1984; Kende, 1993). ACC synthase (S-adenosyl-L-methionine methylethioadenosine-lyase, EC 4.4.1.14), which is encoded by a multigene family, plays a regulatory role in ethylene production. Severa1 genes for ACC synthase have been isolated from tomato (Rottmann et al., 1991), mung bean (Botella et al., 199...

Tomato is one of the most important vegetables in the world. Decay after harvest is a major issue in the development of tomato industry. Currently, the most effective method for controlling decay after harvest is storage of tomato at low temperature combined with usage of chemical bactericide; however, long-term usage of chemical bactericide not only causes pathogen resistance but also is harmf...

We have employed a genetic approach to study the resistance of tomato to the phytopathogenic bacterium Pseudomonas syringae pv tomato. Resistance to P. s. tomato depends upon expression of the Pto locus in tomato, which encodes a protein with similarity to serine/threonine protein kinases and recognizes pathogen strains expressing the avirulence gene avrPto. Eleven tomato mutants were isolated ...

Early plant defense response is characterized by elevation of activity of peroxidases and enhanced insolubilization of hydroxyproline-rich glycoproteins, such as extensin, in the cell wall. The insolubilization process (cross-linking between soluble extensin precursor molecules) is catalyzed by extensin peroxidases. We have ionically eluted extensin peroxidases from intact water-washed suspensi...

Carotenoids are isoprenyl pigments necessary for protection of the photosynthetic apparatus in a11 green plants. One of the intermediate steps in carotenoid biosynthesis is the conversion of phytoene to {-carotene via two dehydrogenation reactions catalyzed by the enzyme PDS. We have previously cloned cDNAs for this enzyme from soybean (Glycine max; Bartley et al., 1991) and tomato (Lycopersico...

Rider is a novel and recently active Ty1-copia-like retrotransposon isolated from the T3238fer mutant of tomato. Structurally, it is delimited by a duplication of target sites and contains two long terminal direct repeats and an internal open reading frame, which encodes a Ty1-copia-type polyprotein with characteristic protein domains required for retrotransposition. The family of Rider element...

Analysis of a collection of 120,892 single-pass ESTs, derived from 26 different tomato cDNA libraries and reduced to a set of 27,274 unique consensus sequences (unigenes), revealed that 70% of the unigenes have identifiable homologs in the Arabidopsis genome. Genes corresponding to metabolism have remained most conserved between these two genomes, whereas genes encoding transcription factors ar...
