Changes in carotenoid profiles and in the expression pattern of the genes in carotenoid metabolisms during fruit development and ripening in four watermelon cultivars

Comparative transcriptome analysis of two contrasting watermelon genotypes during fruit development and ripening

“…The expression level of Cla009122 in the two cultivars was low at ten DAP but rapidly peaked at 34 DAP in both cultivars, and the level in the red-flesh LSW177 was significantly higher than that in COS from 18 to 42 DAP during fruit ripening. This gene is upregulated in different red-flesh watermelon accessions, and its expression is significantly higher in these than in non-red-flesh watermelon during fruit ripening [1, 5, 7, 26]. In yellow-flesh tomato fruits, abnormal transcripts of PSY1 and the loss of function of the enzyme result in a significantly reduced level of phytoene and a very low level of colored carotenoids.…”

“…Two previous quantitative studies used real-time PCR to study the LCYB expression level in different watermelon varieties. One study showed that low transcript levels of LCYB caused lycopene to accumulate in ‘CN62’ with pink flesh, and no significant differences in LCYB expression were detected between red-flesh “CN66” and yellow-flesh “ZXG381” [26]. Another study found no differential expression of LCYB between red (“Black Diamond” and “Festival Hybrid”)- and canary-yellow (“Yellow Doll” and “Yellow Sunshine”)-fleshed watermelon cultivars [31].…”

“…ZEP expression was upregulated only in LSW177 but was lower and stable during fruit ripening in COS. In the yellow-flesh cultivated watermelon “ZXG381”, the transcript variations in ZEP and CHYB strongly correlated with changes in the violaxanthin and lutein contents during ripening [26]. In squash, the upregulation of ZEP and CHYB transcription levels leads to violaxanthin and lutein production [34], respectively.…”

Antioxidant activity, phenolics and UPLC–ESI(–)–MS of extracts from different tropical fruits parts and processed peels

“…Avocado, pineapple, banana, papaya, passion fruit, watermelon and melon are popular tropical fruits and play an important economic role in Brazil (Lv, Li, Liu, Gu, & Zhao, 2015;Silva et al, 2014;Koffi, Vroh, Baudoin, & Zoro, 2014;Contreras-Calderón, Calderón-Jaimes, Guerra-Hernández, & García-Villanova, 2011;Wang, Bostic, & Gu, 2010). An improved knowledge about these fruits' different parts (pulp, peel and seed) and chemical characterization would contribute to the use of this as a source of bioactive molecules (Abdennacer et al, 2015).…”

Clarificação De Suco De Melancia Através De Microfiltração Com Membrana De Acetato De Celulose

“…A melancia (Citrullus lanatus) pertence à família Cucurbitaceae e pode ser considerada terceira fruta mais popular do mundo (Lv et al, 2014). É produzida em áreas livres de longos períodos de gelo e sua utilização é variada, podendo ser na produção de suco, néctar, coquetéis, entre outros (Nabavi-Pelesaraei et al, 2014).…”
