Non-Destructive Assessment of Aroma Volatiles from a Climacteric Near-Isogenic Line of Melon Obtained by Headspace Stir-Bar Sorptive Extraction

Foods (2013)

J.P. Fernández-Trujillo Noelia Dos-Santos Rocío Martínez-Alcaraz Inés Le Bleis

A climacteric aromatic near-isogenic line (NIL) of melon (Cucumis melo L.) SC3-5-1 contained an introgression of the non-climacteric Korean cultivar "Shongwan Charmi" accession PI 161375 (SC) in the genetic background of the non-climacteric cultivar "Piel de Sapo" (PS). The aroma production was monitored during ripening at 21 °C in intact fruit using headspace sorptive bar extraction (HSSE). Bars were composed of polydimethylsiloxane (PDMS) and aromas were desorbed and analyzed by gas-chromatography mass-spectrometry. The aromatic profile was composed of 70 aromatic compounds plus 21 alkanes with a predominance of esters, particularly acetate (2-methylbutyl acetate, 2-methylpropyl acetate, hexyl acetate, and phenylmethyl acetate). Some compounds were severely affected by postharvest time. The acetate esters (3-methylbutyl acetate, butan-2-yl acetate and phenylmethyl acetate) decreased with ripening and sulfur-derived compounds (S-methyl butanethioate and S-methyl 3-methylbutanethioate) increased gradually with ripening. A few compounds increased at the senescence phase (propyl ethanoate). Other compounds such as hexadecanoic acid showed a marked decrease after harvest, some decreasing from a relative maximum at harvest (2-methylpropyl hexanoate; n-hexanoic acid; nonanoic acid).

Thorough Characterization of ETHQB3.5, a QTL Involved in Melon Fruit Climacteric Behavior and Aroma Volatile Composition

Foods (2023)

Noelia Dos-Santos María C. Bueso Aurora Díaz Eduard Moreno Jordi García-Más

The effect of the QTL involved in climacteric ripening ETHQB3.5 on the fruit VOC composition was studied using a set of Near-Isogenic Lines (NILs) containing overlapping introgressions from the Korean accession PI 16375 on the chromosome 3 in the climacteric 'Piel de Sapo' (PS) genetic background. ETHQB3.5 was mapped in an interval of 1.24 Mb that contained a NAC transcription factor. NIL fruits also showed differences in VOC composition belonging to acetate esters, non-acetate esters, and sulfur-derived families. Cosegregation of VOC composition (23 out of 48 total QTLs were mapped) and climacteric ripening was observed, suggesting a pleiotropic effect of ETHQB3.5. On the other hand, other VOCs (mainly alkanes, aldehydes, and ketones) showed a pattern of variation independent of ETHQB3.5 effects, indicating the presence of other genes controlling non-climacteric ripening VOCs. Network correlation analysis and hierarchical clustering found groups of highly correlated compounds and confirmed the involvement of the climacteric differences in compound classes and VOC differences. The modification of melon VOCs may be achieved with or without interfering with its physiological behavior, but it is likely that high relative concentrations of some type of ethylene-dependent esters could be achieved in climacteric cultivars.

AROMA VOLATILES DURING WHOLE MELON RIPENING IN A CLIMACTERIC NEAR-ISOGENIC LINE AND ITS INBRED NON-CLIMACTERIC PARENTS

Acta Horticulturae (2012)

J.P. Fernández-Trujillo M. Fernández-Talavera M. Ruiz-León María J. Roca Noelia Dos-Santos

A climacteric aromatic near-isogenic line (NIL) of melon (Cucumis melo L.) SC3-5-1 was obtained from non-climacteric parents: the Korean cultivar 'Shongwan Charmi' accession PI 161375 (SC), and the cultivar 'Piel de Sapo' (PS). The aroma volatiles of individual fruit of the lines were monitored during ripening at 20°C, using headspace sampling by sorptive bar extraction and gas-chromatography mass-spectrometry. The compounds were grouped and plotted using area counts and relative percentages compared with total area counts of the compounds positively identified or the total headspace. By area, the predominant compounds were esters in SC3-5-1 and SC, while acids and, to a lesser extent, aldehydes, ketones, terpenes and aliphatic compounds were more notable in PS. The most noticeable changes in aroma volatiles associated with the climacteric NIL SC3-5-1 were an increase of total acetate esters, and the sudden conversion of alcohols into non-acetate esters during the first seven days of ripening, coinciding with maximum ethylene production. The area of acetate esters was two- to three-fold higher in SC3-5-1 than in SC. In the non-aromatic SC, the relative levels of acetate and non-acetate esters were around 30-40 and 40-50%, respectively, reaching a relative minimum for acetate and a relative maximum for non-acetate esters. In PS, volatile acids increased during ripening with a peak after 5 d (40%), while the relative level of esters in PS slightly increased after 7 d. The PS aldehydes showed relatively high levels at harvest (35%) but decreased after two days. The SC introgression alone or interacting with the PS genetic background determined the aroma in the climacteric NIL SC3-5-1.

Pre- and Postharvest Muskmelon Fruit Cracking: Causes and Potential Remedies

HortTechnology (2013)

J.P. Fernández-Trujillo Gene E. Lester Noelia Dos-Santos Juan A. Martínez J. Esteva

Fruit cracking is an important disorder that can cause severe loss of marketable yield and revenue in the muskmelon ( Cucumis melo ) fruit industry. The physiological and environmental factors causing cracking are poorly understood. Although generally considered a physiological disorder caused by fluctuating environmental conditions, current evidence indicates that this disorder also has a genetic as well as a genotype × environment component. Certain cultivars are more susceptible than others, but wide fluctuations in irrigation, temperature, and nutrition during late fruit maturation stages appear to predispose fruit to cracking. This article summarizes the current state of our understanding of the causes of fruit splitting in muskmelons.

Differential aroma volatiles in non-climacteric near-isogenic lines of melon as biomarkers of differences of flesh firmness at harvest

J.P. Fernández-Trujillo Noelia Dos-Santos María C. Bueso

Two non-climacteric near-isogenic lines (NILs) of melon (Cucumis melo L.), SC10-2 and SC7-1, containing introgressions of the Korean cultivar \'\'Shongwan Charmi\'\' accession PI161375 (SC) into the Spanish cultivar \'\'Piel de Sapo\'\' (PS) were studied. Data were analysed by different supervised and unsupervised multivariate statistical techniques in order to determine the most discriminant aroma volatiles analyzed by constant flow gas-chromatography mass-spectrometry that could be associated with differences in ripening and flesh firmness in non-climacteric melons. The NILs and the parental showed non-climacteric behaviour during ripening. SC10-2 was harvested at least 7 days later than the control. At harvest, only the NIL SC10-2 showed 65% higher flesh firmness than PS. Whole fruit hardness of SC7-1 was 34% lower than PS. The results obtained by the partial-least square discriminant analysis showed that the aroma better discriminated SC10-2 than SC7-1 from the control, with scarce differences between SC7-1 and PS. The aldehydes (Propanal, 2-methyl-) and the ketones (2-3 Pentanedione) were the most discriminating volatile groups among the NILs studied and PS. Higher levels of several aldehydes (Propanal, 2-methyl-, Benzaldehyde, 2,4-dimethyl-/Benzaldehyde, 3,4-dimethyl-, Butanal, 2-methyl-), not present in PS line, discriminated the NIL SC10-2 from the control PS. Also, SC10-2 displayed lack of some ketones (Acetophenone) and very low presence of alcohols (as for example, Cyclohexanol, 3,5-dimethyl-) compared with PS. The NIL SC7-1 was highlighted by higher relative content in alcohols (1-Octanol, 3-Ethyl-2-heptanol) and one acetate ester (Acetic acid, phenylmethyl ester) than PS and presence of ketones (2-3 Pentanedione, 2-Cyclopenten-1-one, 3,5,5-trimethyl-) that were absent in PS. The results are discussed in terms of the aroma biosynthesis pathways that could be affected by the introgressions.

Near-isogenic lines of melon with different climacteric behavior as a tool to characterize fruit senescence traits 1

Edgardo Moreno Noelia Dos-Santos P. Sanmartin Michael Kessler Antonio Alarcón

Aroma volatiles and fruit quality traits at harvest or after senescence were determined in a collection of near-isogenic lines (NILs) with different climacteric behavior (two non-climacteric NILs more the parental non-climactericPiel de sapo´ and the rest climacteric). Data were analyzed by partial least squares discriminant analysis. In senescent fruit, four ester volatiles (particularly benzyl acetate) helped to discriminate between climacteric and non-climacteric NILs. Aroma volatiles were more efficient for discriminating by senescent or climacteric behavior than fruit quality traits, and flavor traits (dry matter, soluble solids content, titratable acidity, and individual sugars and organic acid content) were more efficient than using other major quality traits (including color, texture, pH, extractable juice and juice density). Particularly flesh firmness was clearly discriminating the fruit of the parental line from the rest either at harvest or after senescence.

Cell Wall Polysaccharides of Near-Isogenic Lines of Melon (Cucumis melo L.) and Their Inbred Parentals Which Show Differential Flesh Firmness or Physiological Behavior

Journal of Agricultural and Food Chemistry (2011)

Noelia Dos-Santos Ana Jiménez‐Araujo Rocío Rodríguez‐Arcos J.P. Fernández-Trujillo

We characterized differences in cell wall material and polysaccharide structures, due to the quantitative trait loci associated with higher flesh firmness in a nonclimacteric near-isogenic line (NIL) SC7-2, and with the climacteric behavior of the NIL SC3-5-1, using their nonclimacteric inbred parentals, "Piel de Sapo" (PS) and PI 161375 (SC). PS was firmer and had a higher ripening index and greater hemicellulosic content than SC, with its lower wall material yield, and uronic acid, neutral sugar, cellulose and free sugar content and higher pectic content. SC3-5-1 showed lower uronic acid values, a higher soluble solid content, and similar flesh firmness to PS. SC3-5-1 yielded mainly high molecular weight polysaccharides in the imidazole-soluble fraction than PS. SC7-2 showed greater flesh firmness, a higher neutral sugar (especially galactose and mannose) and uronic acid content, together with a larger cellulose and α-cellulose residue than PS. SC7-2 also contained more polysaccharides of low molecular weight in the first pectic fraction and shifted toward higher molecular weights in the main peak of the 4 M potassium-soluble fraction compared with PS.
