Numerous studies have shown that the endophytic fungus has a broad range of promoting effects on root development and plant growth in host plants. However, there are currently no reports on the application of this fungus on . This study first compared the colonization ability of on 11 varieties and found that the colonization rate of this fungus on these varieties ranged from 90% to 100%, with the colonization rate of the varieties '09-01' and 'Nongda 7' being as high as 100%.

Chalcone synthase (CHS) is the first key enzyme-catalyzing plant flavonoid biosynthesis. Until now, however, the blueberry CHS gene family has not been systematically characterized and studied. In this study, we identified 22 genes that could be further classified into four subfamilies from the highbush blueberry () genome.

Chinese dwarf cherry () is a wild fruit tree and medicinal plant endemic to China. Its fruits are rich in various bioactive compounds, such as flavonoids and carotenoids, which contribute greatly to their high antioxidant capacity. In this study, the contents of bioactive substances (chlorophyll, carotenoids, ascorbic acid, anthocyanin, total flavonoids, and total phenols), antioxidant capacities, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonicacid) (ABTS) scavenging ability, and ferric-reducing antioxidant power (FRAP)) in differentially pigmented fruits of four varieties were determined and compared.

Jujube witches' broom disease (JWB), caused by , is the most destructive phytoplasma disease threatening the jujube industry. Tetracycline derivatives treatments have been validated to be capable of recovering jujube trees from phytoplasma infection. In this study, we reported that oxytetracycline hydrochloride (OTC-HCl) trunk injection treatment could recover more than 86% of mild JWB-diseased trees.

SNAREs (soluble N-ethylmaleimide-sensitive-factor attachment protein receptors) are engines for almost all of the membrane fusion and exocytosis events in organism cells. In this study, we identified 84 genes from banana (). Gene expression analysis revealed that the expression of s varied a lot in different banana organs.

As one of the most important transcription factors regulating plant anthocyanin biosynthesis, MYB has attracted great attentions. In this study, we identified fifteen candidate anthocyanin biosynthesis related MYB (ABRM) proteins, including twelve R2R3-MYBs and three 1R-MYBs, from highbush blueberry. The subcellular localization prediction results showed that, with the exception of VcRVE8 (localized in chloroplast and nucleus), all of the blueberry ABRMs were nucleus-localized.

Ca- have been confirmed to play very important roles in plant growth and development and in stress responses. However, studies on banana () Ca- are very limited. In this study, we identified 18 Ca- genes from banana, including 6 P-IIA or ER (Endoplasmic Reticulum) type Ca- () and 12 P-IIB or Auto-Inhibited Ca- ().
