The 'Okitsu No. 58' citrus variety is highly prone to fruit cracking, which jeopardizes yield and results in economic losses. In this study, we investigated the impacts of spraying 5 distinct concentrations (0.

Article Synopsis
  • Volatile compounds significantly impact fruit flavor, and a study examined a bud mutant of 'Ehime 38' that exhibits a different volatile profile compared to the wild type (WT).
  • The research identified 35 volatile compounds at five stages of fruit development, finding that while both varieties peaked at the same time, the mutant (MT) consistently had 1.4-2.5 times higher total volatile content, primarily due to increased d-limonene.
  • Analysis revealed that genes in the MEP pathway were positively linked to volatile levels, suggesting that their expression shifts during development contribute to the higher volatiles in the mutant, offering insights for enhancing citrus flavor.

Article Synopsis
  • The gene family is important for chloroplast development and chlorophyll production in citrus but its exact role is not fully understood.
  • This study identified 30 transcription factors in the citrus genome, noting that they show tissue-specific expression across different parts of the plant.
  • Low gene duplication and variations suggest that changes within genes are a key factor in the evolution of these transcription factors in citrus.

'Fengtang' plums soften quickly and lose flavor after harvest. This study comprehensively evaluated the effect of exogenous melatonin on the fruit quality of 'Fengtang' plums. According to our findings, exogenous melatonin prevented plum fruit from losing water, delayed the decline in firmness, and preserved a high TSS/TA level.

Fruit cracking affects both the yield and economic efficiency of citrus; however, the underlying mechanism remains unclear. Therefore, this study focused on resistant and susceptible cultivars to identify the mechanisms underlying fruit cracking. The results showed that in 'Mingrijian', pectin morphological transformation and hemicellulose and lignin degradation in the pericarp were important contributing factors.

In this study, we compared the fruit quality and color of 'Kiyomi' (WT) and its mutant (MT) grafted on Ziyang xiangcheng (Cj) (WT/Cj, MT/Cj), and the MT grafted on Trifoliate orange (Pt) (MT/Pt). The differences in sugar, organic acid, flavonoids, phenols, and volatile substances of the three materials were also analyzed by high performance liquid chromatography (HPLC) and headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS). The results showed significant differences in the appearance of WT/Cj, MT/Cj, and MT/Pt.

Sugars and organic acids are the main factors determining the flavor of citrus fruit. The WRKY transcription factor family plays a vital role in plant growth and development. However, there are still few studies about the regulation of citrus WRKY transcription factors (CsWRKYs) on sugars and organic acids in citrus fruit.

Loss of quality in citrus fruit is a common occurrence during postharvest storage due to oxidative stress and energy consumption. In recent years, glycine betaine (GB) has been widely applied to postharvest horticulture fruit. This study aimed to investigate the effect of GB treatment (10 mM and 20 mM) on the quality and antioxidant activity of 'Huangguogan' fruit during postharvest storage at room temperature.

Objectives: This study aimed to examine the effect of acupuncture on symptoms and health-related quality of life in patients with endometriosis.

Methods: Nine biomedical databases were searched to April 2022 to identify randomized controlled trials of acupuncture and/or moxibustion used alone or as adjunct to guideline-recommended pharmacotherapy for the treatment of endometriosis. One reviewer extracted data and another verified the data.

Article Synopsis
  • Citrus fruits have unique nutritional values and many cultivars arise from mutations, yet the impact of these mutations on fruit quality is unclear.
  • A study investigating the 'Aiyuan 38' cultivar found that a yellowish bud mutant (MT) had a distinctive peel color compared to the wild type (WT), affecting flavor and volatile compounds.
  • Although there were no significant differences in total sugar and acid content, MT showed lower glucose and higher malic acid levels, and released more volatile organic compounds in the pulp compared to the WT, highlighting how mutations can influence citrus fruit quality.

Interstock is an important agronomic technique for regulating plant growth and fruit quality, and overcoming the incompatibility between rootstocks and scions; however, the underlying mechanisms remain largely unknown. In this study, the effects and regulatory mechanisms of tangor grafting, with and without interstocks, on the growth and development of scions were analyzed by combining morphology, physiology, anatomy and transcriptomics. Morphological and physiological analyses showed that interstocks ('Aiyuan 38' and 'Daya') significantly improved the growth of seedlings, effectively enhanced the foliar accumulation of chlorophyll and carotenoids, and increased the thickness of leaf tissues.

Xyloglucan endotransglycosylase () genes are widely distributed in most plants, but the codon usage bias of genes has remained uncharacterized. Thus, we analyzed the codon usage bias using 4500 codons of 20 genes to elucidate the genetic and evolutionary patterns. Phylogenetic and hierarchical cluster analyses revealed that the 20 genes belonged to two groups.
