Uncovering the genetic basis for enhanced mushroom flavor in through genome sequencing and metabolic profiling.

is a common timber oak tree species widely distributed in subtropical areas of China. In this study, we presented a chromosome-scale reference genome assembly of . achieved by integrating PacBio Sequel II, DNBseq™, and Hi-C sequencing platforms, and the results indicated the .

Multi-omics analysis reveals the regulatory mechanism of branching development in Quercus fabri.

The ability of axillary meristems to form axillary buds and subsequently develop into branches is influenced by phytohormones, environmental conditions, and genetic factors. The main trunk of Quercus fabri is prone to branching, which not only impacts the appearance and density of the wood and significantly reduces the yield rate. This study conducted transcriptomic, proteomic, and metabolomic analyses on three stages of axillary bud development in Q.

Transcriptomic Analysis Reveals the Opposite Regulatory Effects of WRKY and CAMTA Transcription Factors on Total Tannin Production in Fruit.

Tannins are prevalent compounds found in plant fruits, contributing to the bitter taste often associated with these fruits and nuts, thereby influencing their overall taste quality. Numerous studies have been conducted to investigate the regulatory factors involved in tannin synthesis. Among these factors, transcription factors exhibit the most significant capacity to regulate tannin production as they can modulate the expression of several key enzyme genes within the tannin synthesis pathway.

Transcriptome analysis reveals important regulatory factors for condensed tannins synthesis in acorn.

Condensed tannins are widely present in the fruits and seeds of plants and effectively prevent them from being eaten by animals before maturity due to their astringent taste. In addition, condensed tannins are a natural compound with strong antioxidant properties and significant antibacterial effects. Four samples of mature and near-mature Quercus fabri acorns, with the highest and lowest condensed tannin content, were used for genome-based transcriptome sequencing.

AP3 promotes the synthesis of condensed tannin in fruit by positively regulating ANR expression.

Condensed tannins are often found in fruits and nuts and have an astringent flavor. The synthesis pathway of condensed tannins is already clear, but few related regulatory factors have been explored. Previous studies about MADS-box transcription factors have mainly focused on the regulation of floral organ development.

Comprehensive identification of transcription factors in reveals candidate gene involved in the monoterpene biosynthesis pathway.

(Lour.) Person, an economically important aromatic plant producing essential oils, has lemon-like fragrance and 96.44-98.

LcERF19, an AP2/ERF transcription factor from , positively regulates geranial and neral biosynthesis.

The APETALA2/ETHYLENE RESPONSE FACTOR (AP2/ERF) transcription factors (TFs) are involved in the regulation of specialized terpenoid biosynthesis. However, the AP2/ERF TFs in have not been characterized and their role in the biosynthesis of terpenoids is unknown. Here, 174 LcAP2/ERF TFs were identified in and categorized into four subfamilies: 27 AP2, 7 RAV, 1 Soloist, and 139 ERF.

Effects of Drought Stress and Rehydration on Physiological and Biochemical Properties of Four Oak Species in China.

Quercus fabri Hance, Quercus serrata Thunb, Quercus acutissima Carruth, and Quercus variabilis BL are four Chinese oak species commonly used for forestation. To ensure the survival of seedlings, we first need to understand the differences in drought resistance of the four oak species at the seedling stage, and comprehensively evaluate their drought resistance capabilities. The four oak seedlings were divided into drought-rewatering treatment group and well watered samples (control group).
