Summary: In this study, proteomic and acetylomic analysis were conducted on longan embryogenic callus and globular embryos. The results revealed that acetylation modifications affected glucose metabolism, carbon metabolism, fatty acid degradation, and oxidative phosphorylation pathways. The use of the deacetylase inhibitor sodium butyrate reduced proliferation and delayed differentiation of the callus by regulating reactive oxygen species and indole-3-acetic acid homeostasis. This study provides insights into the molecular mechanisms of early somatic embryogenesis in longan and has potential implications for genetic improvement.

Summary: The study found that P. indica colonization can promote the growth of longan seedlings by increasing root length, root number, chlorophyll content in leaves, and flavonoid contents in both leaves and stems. The mechanism behind this promotion involves inducing the synthesis of IAA and the activity of POD, while also reducing the accumulation of H2O2 and suppressing the accumulation of JA in the roots.

Summary: Water loss is a key factor in pericarp browning of litchi and longan fruit during storage and transportation. The loss of water mainly affects the pericarp, leading to a denser and thinner texture. However, seeds maintain their vigor and germination rate better when kept in intact fruit, showing a negative correlation with fruit decay index. Browning triggered by water loss helps to maintain seed vigor by preventing dehydration and infection.

Summary: Anthocyanins, health-promoting compounds with strong antioxidant properties, accumulate in the pericarp but not in the aril of litchi fruit. Metabolome and transcriptome analyses revealed that a block in cyanidin glycosylation is responsible for the deficiency of anthocyanin biosynthesis in the aril. Additionally, 9 candidate genes, including LcMYB1, were identified to play a significant role in regulating anthocyanin biosynthesis. This study provides insights into the molecular mechanism of tissue-specific anthocyanin accumulation and will contribute to the development of new red-fleshed litchi germplasm.

Summary: Agrobacterium rhizogenes-mediated hairy root culture is a useful method for gene function analysis and plant secondary metabolite production. In this study, red litchi hairy roots were successfully obtained by transforming with A. rhizogenes-mediated LcMYB1. Anthocyanin profiling and transcriptome analysis revealed significant changes in metabolites and gene expression associated with flavonoid biosynthesis. Key structural genes in anthocyanin biosynthesis were identified, while genes involved in lignin production were down-regulated, indicating a competition between flavonoids and lignin in the phenylpropanoid pathway. Several transcription factors were also found to play a role in regulating anthocyanin biosynthesis in litchi hairy roots. These findings provide insights into the molecular mechanisms of anthocyanin accumulation in litchi hairy roots regulated by LcMYB1.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
