Project description:Anthocyanins are colorful plant pigments with antioxidant properties, and a diet rich in these flavonoids bears health benefits. Therefore, a strong anthocyanin accumulation in edible plant parts is of significant interest, and in Malus domestica, the domesticated apple, certain red-fleshed apple varieties exhibit this trait. Enhanced anthocyanin accumulation in the flesh of apple fruits is attributed to the hyperactivation of the MYB transcription factor MdMYB10, which act as a key regulators of anthocyanin biosynthesis by inducing the expression of multiple biosynthetic genes. While several studies have explored the underlying genetic mutations and resulting transcriptome changes, there is a lack of research on proteome alterations that cause the red-fleshed apple phenotype. To address this gap, a mass spectrometry-based proteomics approach was employed. Comparative proteomics identified differentially abundant proteins in young and mature fruits of the red-fleshed ‘Bay13645’ variety compared to the white-fleshed ‘Royal Gala’. Whereas several MYB transcription factors were enriched during early fruit development, they were no longer among the hyper-abundant proteins in ripe fruits of the red-fleshed genotype. In contrast, anthocyanin biosynthetic enzymes were enriched more strongly in ripe fruits of the red-fleshed cultivar, indicating developmental stage-specific differences in the control of the pigmentation process. The proteomic approach also identified novel regulatory factors and enzymes that may contribute to the red-fleshed apple phenotype, including a BAHD acyltransferase, Mal d proteins, and transcription factors of diverse families, and their potential relevance for the exhibition of this trait is discussed.

Project description:New mechanisms-of-action of anthocyanins (ACNs) provided by a red-fleshed apple compared with a white-fleshed apple ACN-poor, and with an ACN-rich extract on the proteome profile of aorta and heart as cardiovascular key tissues were determined. Hypercholesterolemic Wistar rats were separated into the corresponding groups to analyze the proteomic profile of the aorta and heart tissues using nano-liquid chromatography coupled to mass-spectrometry. Red-fleshed apple downregulated CRP, C1QB and CFP related-inflammation. White-fleshed apple reduced C1QB, CFB, CFD, C3, and C9 related to the complement system, reduced MB and CP related to iron metabolism, and increased ME1, PKM, and PC related to energy homeostasis. ACN-rich extract increased FMOD, TAGLN, and CAP1 related to cellular structure and decreased PRKACA, IQGAP1, and HSP90AB1 related to cellular signaling. Red-fleshed apple rich in ACNs suggested an anti-inflammatory effect while white-fleshed apple reduced the complement system protein-related. An apple matrix effect reduced inflammatory proteins regardless their ACN content.

Project description:To identify miRNAs involved in senescence of strawberry fruit, two independent small RNA libraries and one degradome library from strawberry fruits stored at 20 M-BM-0C for 0 and 24 h were constructed. A total of 18,759,735 and 20,293,492 mappable small RNA sequences were generated in the two small RNA libraries, respectively, and 88 known and 1224 new candidate miRNAs were obtained. Among them, 94 miRNAs were up-regulated and 64 were down-regulated in the senescence of strawberry fruit. Through degradome sequencing, 103 targets cleaved by 19 known miRNAs families and 55 new candidate miRNAs were identified. 14 targets, including NAC transcription factor, Auxin response factors (ARF) and Myb transcription factors, cleaved by 6 known miRNA families and 6 predicted candidates, were found to be involved in regulating fruit senescence. sample 1: Examination of small RNA in strawberry fruits stored at 20 M-BM-0C for 0; sample 2: Examination of small RNA in strawberry fruits stored at 20 M-BM-0C for 24 h

Project description:We have performed a transcriptome analysis of genes at three different ripening stages of the pink-white fruits and the ripe stage of the red fruits of Chinese bayberry. This analysis provided a total of 119,701 unigenes, of which 41.43% were annotated in the Nr database. Our results showed that the formation of the pink-white color in Chinese bayberry fruits depended on the anthocyanin metabolic pathway, regulated by MYB1. Downregulated expression of key anthocyanin biosynthetic pathway genes, such as UFGT, F3’H, and ANS at the late stage of fruits development compared with DK3 fruits resulted in the failure to form red fruits. Our findings shed light on the regulatory mechanisms and metabolic processes that control color development in the fruits of Chinese bayberry.

Project description:Canker disease caused by Neoscytalidium dimidiatum is the most serious disease that attacks the pitaya industry. One pathogenic fungus, referred to as ND8, was isolated from the wild-type red-fleshed pitaya (Hylocereus polyrhizus) of Hainan Province. Here, we studied mainly the host responses of red-fleshed pitaya (H. polyrhizus) cultivars against N. dimidiatum using Illumina RNA-Seq technology.
