2. Involvement of brassinosteroids and ethylene in the control of mitochondrial electron transport chain in postharvest papaya fruit
The plant hormones brassinosteroids (BR) and ethylene (ET) act together to regulate plant metabolism. We used BR and 1-methylcyclopropene (1-MCP, an ET action inhibitor) to elucidate the interactions between both hormones for the regulation of mitochondrial respiratory pathways in papaya fruit. The exogenous application of the 24-epibrassinolide (epiBR) enha

3. Produção, qualidade e conservação de tomates heterozigotos nos locos alcobaça, nonripening e ripening inhibitor
O objetivo deste trabalho foi avaliar os atributos de produtividade, qualidade e conservação pós-colheita de tomates, para comparar os efeitos promovidos pelos alelos alcobaça (norª), nonripening (nor) e ripening inhibitor (rin) em heterozigose, isoladamente ou em duplas combinações, sobre frutos de tomateiros híbridos. Foram avaliados dez tratamento

4. Simultaneous employment of ripening (rin and nor A) and colour (org and hp) mutants as heterozygotes in long shelf life tomato genotypes. / Emprego simultÃneo dos mutantes de amadurecimento (rin e nor A) e de coloraÃÃo (og C e hp) em heterozigose em genÃtipos de tomateiro longa-vida.
Os alelos mutantes ripening inhibitor (rin), alcobaÃa (norA), high pigment (hp) e old gold-crimson (ogc) retardam o processo natural de amadurecimento e/ou alteram a pigmentaÃÃo dos frutos. Foi avaliada a viabilidade do emprego simultÃneo dos mutantes em heterozigose rin, norA, ogc e/ou hp em genÃtipos de tomateiro, utilizando dois backgrounds, visando

5. Estudos genÃtico/fisiolÃgicos dos mutantes alcobaÃa (alc), non ripening (nor), e ripening inhibitor (rin) em tomateiro / Genetic-Physiological studies of the tomato mutants alcobaÃa (alc), non-ripening (nor) e ripening-inhibitor (rin).
The tomato mutants alcobaÃa (alc), non-ripening (nor) and ripening-inhibitor (rin) were compared for their post-harvest effects as homozygotes, as heterozygotes and in their double heterozygous combinations. The genotypes Flora-Dade, TOM-559 (alc/alc), TOM-613 (nor/nor), TOM-614 (rin/rin), F1 [(Flora-Dade x TOM-613)] (nor+/nor), F1 [(Flora-Dade x TOM-559)]

6. Acetaldehyde Is a Causal Agent Responsible for Ethanol-Induced Ripening Inhibition in Tomato Fruit.
Inhibition of tomato (Lycopersicon esculentum Mill.) fruit ripening by exogenously applied ethanol was shown to be caused by elevated endogenous levels of acetaldehyde (AA). Exposure of excised pericarp discs of mature-green tomato fruit to ethanol or AA vapors produced elevated levels of both compounds in the tissue, but only the levels of AA were associate

7. Ethylene-regulated expression of a tomato fruit ripening gene encoding a proteinase inhibitor I with a glutamic residue at the reactive site.
We report the isolation from tomato (Lycopersicon esculentum) of an ethylene-responsive member of the proteinase inhibitor gene family. DNA sequence analysis of a full-length cDNA clone indicates that the ethylene-responsive gene is distantly related to the tomato proteinase inhibitor I gene, having 53% sequence identity. The predicted amino acid sequence re

8. Subcellular Distributions of Isoenzymes in Fruits of a Normal Cultivar of Tomato and of the rin Mutant at Two Stages of Development
Fruits of tomato (Lycopersicon esculentum Mill.) cv. Rutgers and of a nearly isogenic stock containing the ripening inhibitor gene rin harvested at green (66% mature) and ripe (107% mature) stages were studied for the subcellular distribution of isoenzymes using isoelectric focusing. The enzymes studied were peroxidases, esterases, phosphatases, phosphorylas

9. Expression of a chimeric polygalacturonase gene in transgenic rin (ripening inhibitor) tomato fruit results in polyuronide degradation but not fruit softening.
Tomato fruit ripening is accompanied by extensive degradation of pectic cell wall components. This is thought to be due to the action of a single enzyme, polygalacturonase, whose activity is controlled, at least in part, at the level of gene expression. At the onset of tomato fruit ripening, polygalacturonase enzyme activity, mRNA levels, and relative rate o

10. Ethylene-Mediated Posttranscriptional Regulation in Ripening Avocado (Persea americana) Mesocarp Discs.
Discs of avocado (Persea americana) fruit (15 x 3 mm thick) kept in a stream of moist air ripen within 72 h. Following cutting, a modest evolution of wound ethylene that dissipates in 24 h is followed by a burst of autocatalytic ethylene production associated with a respiratory climacteric, much as in the intact fruit. Aminoethoxyvinylglycine (AVG), an inhib

11. Differential Expression and Internal Feedback Regulation of 1-Aminocyclopropane-1-Carboxylate Synthase, 1-Aminocyclopropane-1-Carboxylate Oxidase, and Ethylene Receptor Genes in Tomato Fruit during Development and Ripening1
We investigated the feedback regulation of ethylene biosynthesis in tomato (Lycopersicon esculentum) fruit with respect to the transition from system 1 to system 2 ethylene production. The abundance of LE-ACS2, LE-ACS4, and NR mRNAs increased in the ripening fruit concomitant with a burst in ethylene production. These increases in mRNAs with ripening

12. Ethylene Insensitivity Conferred by the Green-ripe and Never-ripe 2 Ripening Mutants of Tomato1
The ripening of a fleshy fruit represents the summation of an array of biochemical processes that are regulated by interactions between developmental programs and environmental inputs. Analysis of tomato (Solanum lycopersicum) mutants and inhibitor studies indicate that ethylene is necessary for full development of the ripening program of climacteric fruit s
