Modifications in Organic Acid Profiles During Fruit Development and Ripening: Correlation or Causation?
Frontiers in Plant Science, 2018Co-Authors: Willian Batista-silva, Dimas M. Ribeiro, David B Medeiros, Vitor L Nascimento, Agustin Zsögön, Adriano Nunes-nesi, Wagner L AraujoAbstract:The pivotal role of phytohormones during Fruit Development is considered established knowledge in plant biology. Perhaps less well-known is the growing body of evidence suggesting that organic acids play a key function in plant Development and, in particular, in Fruit Development and maturation. Here, we critically review the connection between organic acids and the Development of both climacteric and non-climacteric Fruits. By analyzing the metabolic content of different Fruits during their ontogenetic trajectory, we noticed that the content of organic acids in the early stages of Fruit Development is directly related to the supply of substrates for respiratory processes. Although different organic acid species can be found during Fruit Development in general, it appears that citrate and malate play major roles in this process, as they accumulate on a broad range of climacteric and non-climacteric Fruits. We further highlight the functional significance of changes in organic acid profile in Fruits due to either the manipulation of Fruit-specific genes or the use of Fruit-specific promoters. Despite the complexity behind the fluctuation in organic acid content during Fruit Development, we extend our understanding on the importance of organic acids on Fruit metabolism and the need to further boost future research. We suggest that engineering organic acid metabolism could improve both qualitative and quantitative traits of crop Fruits.

TIR1-like auxin-receptors are involved in the regulation of plum Fruit Development
Journal of Experimental Botany, 2014Co-Authors: Islam El-sharkawy, Isabelle Mila, Mondher Bouzayen, Sherif Sherif, Brian Jones, Prakash P. Kumar, Subramanian JayasankarAbstract:Ethylene has long been considered the key regulator of ripening in climacteric Fruit. Recent evidence showed that auxin also plays an important role during Fruit ripening, but the nature of the interaction between the two hormones has remained unclear. To understand the differences in ethylene- and auxin-related behaviours that might reveal how the two hormones interact, we compared two plum (Prunus salicina L.) cultivars with widely varying Fruit Development and ripening ontogeny. The early-ripening cultivar, Early Golden (EG), exhibited high endogenous auxin levels and auxin hypersensitivity during Fruit Development, while the late-ripening cultivar, V98041 (V9), displayed reduced auxin content and sensitivity. We show that exogenous auxin is capable of dramatically accelerating Fruit Development and ripening in plum, indicating that this hormone is actively involved in the ripening process. Further, we demonstrate that the variations in auxin sensitivity between plum cultivars could be partially due to PslAFB5, which encodes a TIR1-like auxin receptor. Two different PslAFB5 alleles were identified, one (Pslafb5) inactive due to substitution of the conserved F-box amino acid residue Pro61 to Ser. The early-ripening cultivar, EG, exhibited homozygosity for the inactive allele; however, the late cultivar, V9, displayed a PslAFB5/afb5 heterozygous genotype. Our results highlight the impact of auxin in stimulating Fruit Development, especially the ripening process and the potential for differential auxin sensitivity to alter important Fruit Developmental processes.

Regulation of two germin-like protein genes during plum Fruit Development
Journal of experimental botany, 2010Co-Authors: Islam El-sharkawy, Isabelle Mila, Mondher Bouzayen, Subramanian JayasankarAbstract:Germin-like proteins (GLPs) have several proposed roles in plant Development and defence. Two novel genes (Ps-GLP1 and 2) encoding germin-like protein were isolated from plum (Prunus salicina). Their regulation was studied throughout Fruit Development and during ripening of early and late cultivars. These two genes exhibited similar expression patterns throughout the various stages of Fruit Development excluding two important stages, pit hardening (S2) and Fruit ripening (S4). During Fruit Development until the ripening phase, the accumulation of both Ps-GLPs is related to the evolution of auxin. However, during the S2 stage only Ps-GLP1 is induced and this could putatively be in a H2O2-dependent manner. On the other hand, the diversity in the Ps-GLPs accumulation profile during the ripening process seems to be putatively due to the variability of endogenous auxin levels among the two plum cultivars, which consequently change the levels of autocatalytic ethylene available for the Fruit to co-ordinate ripening. The effect of auxin on stimulating ethylene production and in regulating Ps-GLPs transcripts was also investigated. These data, supported by their localization in the extracellular matrix, suggest that auxin is somehow involved in the regulation of both transcripts throughout Fruit Development and ripening.

proteomic analysis reveals dynamic regulation of Fruit Development and sugar and acid accumulation in apple
Journal of Experimental Botany, 2016Co-Authors: Fengjuan Feng, Sheng Zhang, Lailiang ChengAbstract:Understanding the Fruit Developmental process is critical for Fruit quality improvement. Here, we report a comprehensive proteomic analysis of apple Fruit Development over five growth stages, from young Fruit to maturity, coupled with metabolomic profiling. A tandem mass tag (TMT)-based comparative proteomics approach led to the identification and quantification of 7098 and 6247 proteins, respectively. This large-scale proteomic dataset presents a global view of the critical pathways involved in Fruit Development and metabolism. When linked with metabolomics data, these results provide new insights into the modulation of Fruit Development, the metabolism and storage of sugars and organic acids (mainly malate), and events within the energy-related pathways for respiration and glycolysis. We suggest that the key steps identified here (e.g. those involving the FK2, TST, EDR6, SPS, mtME and mtMDH switches), can be further targeted to confirm their roles in accumulation and balance of fructose, sucrose and malate. Moreover, our findings imply that the primary reason for decreases in amino acid concentrations during Fruit Development is related to a reduction in substrate flux via glycolysis, which is mainly regulated by fructose-bisphosphate aldolase and bisphosphoglycerate mutase.

The shaded side of apple Fruit becomes more sensitive to photoinhibition with Fruit Development.
Physiologia plantarum, 2008Co-Authors: Lailiang ChengAbstract:Developmental changes of photochemical and non-photochemical processes and the antioxidant system in the shaded peel vs the sun-exposed peel of 'Gala' apple and their responses to sudden exposure of high light were determined to understand the susceptibility of the shaded peel to high light damage with Fruit Development. As Fruit developed, actual PSII efficiency of the shaded peel decreased, whereas non-photochemical quenching (mainly the slow component) increased at any given PFD. Photochemical quenching coefficient of the shaded peel decreased at any given PFD with Fruit Development. As Fruit developed, the activity of superoxide dismutase, ascorbate peroxidase and dehydroascorbate reductase and the level of reduced ascorbate and total ascorbate decreased; the activity of monodehydroascorbate reductase and glutathione reductase remained low, whereas catalase activity and the level of reduced glutathione and total glutathione increased in the shaded peel. Exposure to high light (1500 micromol m(-2) s(-1)) for 2 h significantly decreased the maximum quantum efficiency of PSII (F(V)/F(M)) in the shaded peel at each Developmental stage, with the decrease being larger with Fruit Development. The F(V)/F(M) of the sun-exposed peel was also decreased by the high light treatment, but the decrease was much smaller than that in the shaded peel at each Developmental stage. We conclude that the shaded peel of apple Fruit becomes more sensitive to photoinhibition with Fruit Development, and this increased sensitivity is apparently related to the decease in the overall capacity for photosynthesis and photoprotection of the shaded peel with Fruit Development.
