“…Peptide methionine sulfoxide reductase and universal stress protein A-like protein genes that could be involved in the protective roles were also upregulated. In line with our results, Lopez et al [69] and Tkaczuk et al [70] reported the upregulation of peptide methionine sulfoxide reductase and universal stress protein A-like protein genes to overcome stress conditions. Moreover, there was an upregulation of the gene that encodes peroxidase, the enzyme that catalyzes the reduction of peroxides and the polymerization of toxic compounds [71].…”

Fruit ripening involves changes in physical, physiological and metabolic activities through the actions of enzymes and regulatory genes. This study was initiated to identify the genes related to the ripening of kiwifruit. Gold ‘Haegeum’ kiwifruit is a yellow-fleshed kiwifruit cultivar usually used for fresh marketing. The fruit is harvested at a physiologically mature but unripe stage for proper storage, marketing distribution and longer shelf life. To identify the differentially expressed genes (DEGs) during ripening, fruit treated with ethylene were compared with control fruit that ripened naturally without ethylene treatment. Firmness, respiration rate, ethylene production rate, total soluble solids (TSS), titratable acidity (TA), brix acid ratio (BAR) and overall acceptability were taken during the study as fruit ripening indicators. Total mRNAs were sequenced by Illumina high-throughput sequencing platform and the transcriptome gene set was constructed by de novo assembly. We identified 99,601 unigenes with an average length of 511.77 bp in transcriptome contigs. A total of 28,582 differentially expressed unigenes were identified in the ethylene treatment vs. control. Of these 28,582 unigenes, 13,361 and 15,221 genes were up- and downregulated, respectively, in the treated fruit. The results also showed that 1682 and 855 genes were up- and downregulated, respectively, more than 2-fold at p < 0.05 in fruit treated with ethylene as compared with the control fruit. Moreover, we identified 75 genes showing significantly different expression; 42 were upregulated, and 33 were downregulated. A possible category of the identified ripening-related genes was also made. The findings of this study will add to the available information on the effect of ethylene treatment on ripening and the related changes of kiwifruit at the genomic level, and it could assist the further study of genes related to ripening for kiwifruit breeding and improvement.

“…5a). In other plant species, it is worth mentioning that a very high level of expression of a gene related to AtMSRA1 has been reported in strawberry fruits during the ripening stage (Lopez et al 2006). The corresponding transcript is neither detected in immature fruits, nor in other plant organs (Lopez et al 2006 …”

Methionine oxidation to methionine sulfoxide (MetSo), which results in modification of activity and conformation for many proteins, is reversed by an enzyme present in most organisms and termed as methionine sulfoxide reductase (MSR). On the basis of substrate stereospecificity, two types of MSR, A and B, that do not share any sequence similarity, have been identified. In the present review, we first compare the multigenic MSR families in the three plant species for which the genome is fully sequenced: Arabidopsis thaliana, Oryza sativa, and Populus trichocarpa. The MSR gene content is larger in A. thaliana (five MSRAs and nine MSRBs) compared to P. trichocarpa (five MSRAs and four MSRBs) and O. sativa (four MSRAs and three MSRBs). A complete classification based on gene structure, sequence identity, position of conserved reactive cysteines and predicted subcellular localization is proposed. On the basis of in silico and experimental data originating mainly from Arabidopsis, we report that some MSR genes display organ-specific expression patterns and that those encoding plastidic MSRs are highly expressed in photosynthetic organs. We also show that the expression of numerous MSR genes is enhanced by environmental conditions known to generate oxidative stress. Thioredoxins (TRXs) constitute very likely physiological electron donors to plant MSR proteins for the catalysis of MetSO reduction, but the specificity between the numerous TRXs and methionine sulfoxide reductases (MSRs) present in plants remains to be investigated. The essential role of plant MSRs in protection against oxidative damage has been recently demonstrated on transgenic Arabidopsis plants modified in the content of cytosolic or plastidic MSRA.

“…Oxidative stress also causes protein oxidation and lipid peroxidation. The overexpression of peptide Met sulfoxide reductase (E4; spots 58 and 60) after ethylene induction during ripening is, on the other hand, well documented in tomato and strawberry fruit (Lincoln et al, 1987;Lopez et al, 2006). This protein is implicated in repair of oxidized damaged proteins.…”

Tomato (Solanum lycopersicum) is a model plant for studying fleshy fruit development. Several genetic and molecular approaches have been developed to increase our knowledge about the physiological basis of fruit growth, but very few data are yet available at the proteomic level. The main stages of fruit development were first determined through the dynamics of fruit diameter and pericarp cell number. Then, total proteins were extracted from pericarp tissue at six relevant developmental stages and separated by two-dimensional gel electrophoresis. Protein patterns were markedly different between stages.Proteins showing major variations were monitored. We identified 90 of 1,791 well-resolved spots either by matrix-assisted laser-desorption ionization time-of-flight peptide mass fingerprinting or liquid chromatography-mass spectrometry sequencing and expressed sequence tag database searching. Clustered correlation analysis results pointed out groups of proteins with similar expression profiles during fruit development. In young fruit, spots linked to amino acid metabolism or protein synthesis were mainly expressed during the cell division stage and down-regulated later. Some spots linked to cell division processes could be identified. During the cell expansion phase, spots linked to photosynthesis and proteins linked to cell wall formation transiently increased. In contrast, the major part of the spots related to C compounds and carbohydrate metabolism or oxidative processes were up-regulated during fruit development, showing an increase in spot intensity during development and maximal abundance in mature fruit. This was also the case for spots linked to stress responses and fruit senescence. We discuss protein variations, taking into account their potential role during fruit growth and comparing our results with already known variations at mRNA and metabolite-profiling levels.
