“…These trends were consistent with the observed changes in fruit color and total flavonoid content. Similar results were observed for flavonoids, and anthocyanin presented an upward tendency in Lycium chinense fruit during development [22], while it has been reported that total flavonoid contents declined in Prunus humilis as fruit ripening progressed [23]. These findings suggest that flavonoid metabolism is an intricate process, and different fruits possess specific networks in governing the biosynthesis of flavonoids during ripening.…”

Pineapple color yellowing and quality promotion gradually manifest as pineapple fruit ripening progresses. To understand the molecular mechanism underlying yellowing in pineapples during ripening, coupled with alterations in fruit quality, comprehensive metabolome and transcriptome investigations were carried out. These investigations were conducted using pulp samples collected at three distinct stages of maturity: young fruit (YF), mature fruit (MF), and fully mature fruit (FMF). This study revealed a noteworthy increase in the levels of total phenols and flavones, coupled with a concurrent decline in lignin and total acid contents as the fruit transitioned from YF to FMF. Furthermore, the analysis yielded 167 differentially accumulated metabolites (DAMs) and 2194 differentially expressed genes (DEGs). Integration analysis based on DAMs and DEGs revealed that the biosynthesis of plant secondary metabolites, particularly the flavonol, flavonoid, and phenypropanoid pathways, plays a pivotal role in fruit yellowing. Additionally, RNA-seq analysis showed that structural genes, such as FLS, FNS, F3H, DFR, ANR, and GST, in the flavonoid biosynthetic pathway were upregulated, whereas the COMT, CCR, and CAD genes involved in lignin metabolism were downregulated as fruit ripening progressed. APX as well as PPO, and ACO genes related to the organic acid accumulations were upregulated and downregulated, respectively. Importantly, a comprehensive regulatory network encompassing genes that contribute to the metabolism of flavones, flavonols, lignin, and organic acids was proposed. This network sheds light on the intricate processes that underlie fruit yellowing and quality alterations. These findings enhance our understanding of the regulatory pathways governing pineapple ripening and offer valuable scientific insight into the molecular breeding of pineapples.

“…This is most likely due to the selection of nutritionally valuable individuals by L. barbarum during the development of the variety. It also proves that the variety development of Lycium barbarum is indispensable for the resource utilization of this plant (Li et al, 2019;Qiao et al, 2022;Chen et al, 2017). LN-1 in L. barbarum (Ningqi series) has only a weak oxidation band at 0.2 V. This is unique fingerprint information for this variety.…”

Identification of plant species and variety has important application value in the process of agricultural production. In this work, we try to use electrochemical fingerprinting technology to collect the electrochemical behavior of electrochemically active substances in plant leaf tissues. Twenty Lycium species and varieties were specifically selected to investigate the recognition ability of electrochemical fingerprinting. Two different extraction solvents and electrolytes were used to create different collection environments. The results show that different Lycium spp. can exhibit different electrochemical fingerprints. Different species of the same species exhibit relatively similar electrochemical fingerprints. After the second derivative processing, the electrochemical fingerprint of plants can be used for classification and recognition by different machine learning models. Partial least squares discriminant analysis (PLS-DA), k-nearest neighbor, (KNN), support vector machine (SVM), random forest (RF) and stochastic gradient boosting (SGB) were used to establish recognition model of Lycium spp. The results show that SGB has the best identification accuracy for electrochemical fingerprint after second derivative treatment.

“…During the development of Lycium chinense Miller fruits, the trend of flavonoid content was increased with the gradual maturation of the fruit. It was shown to be higher at the late stage of development [29] . Similarly, the material was different and it did not show the effect of K on nutrients of Goji.…”

To investigate the effects of potassium (K) application on the agronomic traits and fruit quality of Lycium barbarum L. (Goji), three levels of K fertilizer, namely LK (25 g/plant), CK (50 g/plant), and HK (75 g/plant), were applied to plants in phytotron for observing and measuring relevant indicators. The investigation involved seven agronomic traits: plant height, plant stem diameter, new branch increment, yield of fresh fruits per plant, dry fruit quantity within 50 g, ratio of different grade fruits, and ratio of longitudinal diameter to transverse diameter of Goji fruits. The results showed that K application level had significant effect on ratio of the longitudinal diameter to the transverse diameter of fresh Goji fruits, and that the influence on other agronomic traits was slight. In the meanwhile, the concentrations of amino acids, betaine, polysaccharides and flavonoids of Goji fruits in different levels of K fertilizer were tested. The K treatment increased the content of glutamic acid, and decreased that of flavonoids (P < 0.05), whereas the content of other amino acids, polysaccharides and betaine were unaffected. A total of 132 flavonoid metabolites was identified. Among them, K treatment up-regulated 36 metabolites and down-regulated 30 metabolites (P < 0.05). The results provided a basis for balanced K supply to regulate the agronomic traits and nutrients of Goji fruits.
