restriction fragment length polymorphism; loci; clones; chromosome walking; gametogenesis; genes; mutants; yeast artificial chromosomes; genetic recombination; pollen; genetic markers; Solanum lycopersicum var. lycopersicum
Abstract:
... Pollen development requires both sporophytic physic and gametophytic gene expression. We are using a map-based cloning technique to isolate sporophytic a genes which, when mutant, cause pollen abortion and a male sterile (ms) phenotype in tomato (Lycopersicon esculentum). We have genetically characterized one ms locus (ms14) using RFLP analysis and identified flanking markers. High-resolution geno ...

The codons for the amino acid residues making up the proposed ATP-binding sites of the maize (Zea mays L.) endoplasmic reticulum and tomato (Lycopersicon esculentum) cytoplasmic Stress70 proteins were deleted from their respective cDNAs. The deletions had little effect on the predicted secondary structure characteristics of the encoded proteins. Both wild-type and mutant proteins were expressed in ...

The role of systemin in Pin2 gene expression was analyzed in wild-type plants of potato (Solanum tuberosum L.) and tomato (Lycopersicon esculentum Mill.), as well as in abscisic acid (ABA)-deficient tomato (sitiens) and potato (droopy) plants. The results showed that systemin initiates Pin2 mRNA accumulation only in wildtype tomato and potato plants. As in the situation after mechanical wounding, ...

The highest quality level and the most stabilized composts with the highest values of total N (1.3-1.6%) and the smallest C/N ratios (8.0-9.0) were found with the vine branch composts. Compost application significantly increased the yield of tomatoes (24.0-61.1%) a ...

Chemical defense of the tomato plant against noctuid larvae is argued to result from suites of interactive chemical traits that simultaneously impair the acquisition of nutrients and toxify the insect. Defense results from tomatine, catecholic phenolics and phenol oxidases, proteinase inhibitors, and lipoxygenase. The catalytic role of plant oxidative enzymes in activating a variety of defense mec ...

Transgenic plants with altered extracellular acid invertase have highly disturbed growth habits. We investigated the role of intracellular soluble acid invertase in plant and fruit development. Transgenic tomato (Lycopersicon ...

Previous work using microinjection into single cells of the tomato aurea mutant demonstrated that phytochrome A-dependent activation of rbcS and chs genes was mediated by calcium and cGMP, respectively. This work sought to identify promoter cis-elements that respond to these two small molecules. Box II and Unit I, derived from rbcS-3A and chs promoters, respectively, were previously shown to funct ...

Beet armyworm larvae, Spodoptera exigua, and leafminers, Liriomyza trifolii, were used to assay the induced resistance. In whole-plant experiments, damage localized to a single leaflet of four-leaf tomato plants induced a systemic increase in resis ...

Abstract:
... Several studies have indicated that chlorate (ClO3-) and nitrate (NO3-) may share a common transport system in higher plants. Here, we compared the interactions between ClO3- and NO3- uptake by roots of intact tomato (Lycopersicon esculentum cv T5) plants. Exposure to ClO3- for more than 2 h inhibited both net ClO3- and K+ uptake, presumably because of ClO3-toxicity; consequently, subsequent measu ...

Susceptible plants infected by Pseudomonas solanacearum usually wilt, largely due to extracellular proteins (EXPs) and the high-molecular-mass extracellular polysaccharide (EPS I) this pathogen produces. Circumstantial evidence suggested that a 28-kDa protein, the single most abundant EXP made by P. solanacearum in culture, is associated with production of EPS I, and thus might have a role in path ...
