    (This article belongs to this Special Issue: Enhancing the Carbon Sequestration Capacity of the Agricultural, Forestry, and Agroforestry Ecosystems)
    Abstract The contents of carbon (C), nitrogen (N), and phosphorus (P) in soil-microorganisms-plant significantly affect tea quality by altering the main quality components of tea, such as tea polyphenols, amino acids, and caffeine. However, few studies have quantified the effects of these factors on the main quality components of tea. The study aimed to explore the interactions of C, N, and P in soil-microorganisms-plants and the effects of these factors on the main quality components of tea by using the path analysis method. The results indicated that (1) The contents of C, N, and P in soil, microorganisms, and tea plants… More >

    Abstract Grapes, one of the oldest tree species globally, are rich in vitamins. However, environmental conditions such as low temperature and soil salinization significantly affect grape yield and quality. The glutamate receptor (GLR) family, comprising highly conserved ligand-gated ion channels, regulates plant growth and development in response to stress. In this study, 11 members of the VvGLR gene family in grapes were identified using whole-genome sequence analysis. Bioinformatic methods were employed to analyze the basic physical and chemical properties, phylogenetic trees, conserved domains, motifs, expression patterns, and evolutionary relationships. Phylogenetic and collinear analyses revealed that the VvGLRs were divided into three… More >

    The Identification of Phenylalanine Ammonia-Lyase (PAL) Genes from Pinus yunnanensis and an Analysis of Enzyme Activity in vitro

    Dejin Mu1,2, Lin Chen1,2, Heze Wang1,2, Zhaoliu Hu1,2, Sihui Chen1,2, Shi Chen1,2, Nianhui Cai1,2, Yulan Xu1,2, Junrong Tang1,2,*

    Abstract Phenylalanine ammonia lyase (PAL) is the rate-limiting and pivotal enzyme of the general phenylpropanoid pathway, but few reports have been found on PAL genes in Pinus yunnanensis. In the present study, three PAL genes were cloned and identified from P. yunnanensis seedlings for the first time, namely, PyPAL-1, PyPAL-2, and PyPAL-3. Our results indicated that the open-reading frames of PyPAL genes were 2184, 2157, and 2385 bp. Phylogenetic tree analysis revealed that PyPALs have high homology with other known PAL genes in other plants. In vitro enzymatic analysis showed that all three PyPAL recombinant proteins could catalyze the deamination of… More >

    Effects of Flowering Mode and Pollinator Sharing on Reproductive Success in Natural Hybrid of Two Epimedium (Berberidaceae) Species

    Lanying Chen1,2, Qiumei Quan3,*, Yunxiang Li3
    Phyton-International Journal of Experimental Botany, DOI:10.32604/phyton.2024.048103
    Abstract Mediated by pollen flow, natural hybridization is deemed a crucial factor that propels speciation in floral plants. Despite the fact that the diversity of Epimedium species is concentrated mainly in Southwestern China, the potential impact of interspecific pollination on natural hybridization has yet to be empirically scrutinized. To explore this, we studied the flowering period and the visitors of flowers in three frequently overlapping Epimedium species at Jinchengshan National Forest Park, located in Nanchong, Sichuan Province. Additionally, we performed a series of pollination experiments to examine breeding systems and hybrid compatibility. Morphologically, Epimedium pubescens and Epimedium wushanense are clearly distinct… More >

    Impact of Different Rates of Nitrogen Supplementation on Soil Physicochemical Properties and Microbial Diversity in Goji Berry

    Xiaojie Liang1,2, Wei An2, Yuekun Li2, Yajun Wang2, Xiaoya Qin2, Yanhong Cui1, Shuchai Su1,*
    Phyton-International Journal of Experimental Botany, DOI:10.32604/phyton.2024.047628
    Abstract

    Goji berry (Lycium barbarum L.) is substantially dependent on nitrogen fertilizer application, which can significantly enhance fruit yield and Goji berry industrial development in Ningxia, China. This study aimed to analyze the functions of differential nitrogen application rates including low (N1), medium (N2), and high (N3) levels in soil microbial community structure (bacterial and fungal) at 2 diverse soil depths (0–20, 20–40 cm) through high-throughput sequencing technology by targeting 16S RNA gene and ITS1 & ITS2 regions. All the observed physicochemical parameters exhibited significant improvement (p < 0.05) with increased levels of nitrogen and the highest values for most parameters… More >

    Phenolic Profile and Volatiles of in vitro Propagated Lavandula angustifolia Mill. Seedlings

    Mir Abdullatif Yahya1, Fatma Tunali1, Dilek Killi2,*, Atalay Sökmen2
    Phyton-International Journal of Experimental Botany, DOI:10.32604/phyton.2024.046271
    Abstract An effective in vitro propagation protocol was designed for Lavandula angustifolia Miller, a medicinal aromatic plant that is a prominent source of volatile organic compounds (VOCs). Murashige and Skoog media were supplemented with various concentrations of Plant Growth Regulators (PGRs), and the growth parameters of the nodal segments were examined. Nodal explants formed callus when they were supplemented with 2 mg/L of 6-Benzylaminopurine (BAP). The superior hormonal concentration of Murashige and Skoog (MS) media for the proliferation of shoots from callus cultures (39.33%) was 5 mg/L of 2-Isopentenyl adenine (2iP), and the favorable media for the growth of L. angustifoliaMore >

    Identification and Transcriptional Regulation of CAMTA Genes in Liriodendron chinense

    Kaiyue Hong, Yasmina Radani, Teja Manda, Jinhui Chen, Liming Yang*
    Phyton-International Journal of Experimental Botany, DOI:10.32604/phyton.2024.047739
    Abstract This study explores CAMTA genes in the rare and endangered Chinese plant species, Liriodendron chinense. Despite the completion of whole-genome sequencing, the roles of CAMTA genes in calcium regulation and stress responses in this species remain largely unexplored. Within the L. chinense genome, we identified two CAMTA genes, Lchi09764 and Lchi222536, characterized by four functional domains: CG-1, TIG, ANK repeats, and IQ motifs. Our analyses, including phylogenetic investigations, cis-regulatory element analyses, and chromosomal location studies, aim to elucidate the defining features of CAMTA genes in L. chinense. Applying Weighted Gene Co-Expression Network Analysis (WGCNA), we explored the impact of CAMTAMore >
