On the Cover

Catalpa bungei is a Chinese originated ornamental tree. In recent years, lysine acetylome has been extensively investigated in plants, but the information of lysine acetylation during flower development of woody angiosperm remains unclear. In this issue, Jing et al. used the analyses of anti-acetyllysine-based enrichment and high-sensitive mass spectrometry to investigate the lysine acetylation proteome in the C. bungei flower buds. They identified that these key lysine-acetylated proteins were involved in energy metabolism during flower development.

    Abstract Horticulture is a branch of Agricultural science where it is defined as the science and art of cultivating and handling fruits, vegetables, ornamental plants and several plants having unique medicinal and aromatic values. Horticultural crops provide farmers with high income and have good export quality, but they have a concern about postharvest losses. Hence, increasing productivity and decreasing post-harvest losses by using scientific studies and techniques like biotechnology and nanotechnology could be the simplest possible solution to the above-mentioned problems. Using nanotechnology which is having the characteristics of nanoparticles is proven to be very useful in science and technological applications.… More >

    Danlong Jing1,2, Nan Wang1, Nan Lu1, Guanzheng Qu3, Guolu Liang2, Wenjun Ma1, Shougong Zhang1,*, Junhui Wang1,*
    Phyton-International Journal of Experimental Botany, Vol.91, No.3, pp. 507-524, 2022, DOI:10.32604/phyton.2022.017644
    Abstract Lysine acetylation, a reversible and dynamic post-translational modification, plays pivotal roles in regulating many biological processes in plants. However, the information of lysine acetylation during flower development of woody angiosperm remains unclear. Herein, we identified a total of 667 lysine acetylation sites in 467 proteins in flower buds of Catalpa Bungei. The acetylated proteins were mainly involved in the pathways of carbon metabolism, glycometabolism and oxidative phosphorylation. Using functional enrichment analysis, 61 and 13 acetylated proteins were involved in the glycometabolism and oxidative phosphorylation pathways, respectively. This suggests that lysine acetylated proteins play critical roles in the energy metabolism pathways.… More >

    Abstract The complex composition of herbal metabolites necessitates the development of powerful analytical techniques aimed to identify the bioactive components. The seeds of Descurainia sophia (SDS) are utilized in China as a cough and asthma relieving agent. Herein, a dimension-enhanced integral approach, by combining ultra-high performance liquid chromatography/ion mobility-quadrupole time-of-flight mass spectrometry (UHPLC/IM-QTOF-MS) and intelligent peak annotation, was developed to rapidly characterize the multicomponents from SDS. Good chromatographic separation was achieved within 38 min on a UPLC CSH C18 (2.1 × 100 mm, 1.7 μm) column which was eluted by 0.1% formic acid in water (water phase) and acetonitrile (organic phase).… More >

    Abstract Endometriosis is a chronic inflammatory disease that occurs due to the presence of endometrial tissue outside the uterine cavity. It affects from 5% to 10% of women of reproductive age. High levels of matrix metalloproteinase (especially MMP-9) have been observed in women suffering from endometriosis. Thus, the aim of this study was to investigate the naturally anti-inflammatory compounds available from an algal source that can target the MMP-9 by various in silico approaches. The target 1L6J (Crystal structure of human matrix metalloproteinase MMP-9) structure was retrieved from the PDB database. Five compounds such as Eckol, Sargafuran, Vitamin E, Docosahexaenoic acid,… More >

    Muslum S. Inal1,2, Dilek Unal1,*, Bengu Turkyilmaz Unal3,*, Munir Ozturk4
    Phyton-International Journal of Experimental Botany, Vol.91, No.3, pp. 583-598, 2022, DOI:10.32604/phyton.2022.018223
    Abstract Putrescine is reported to be necessary for cold acclimation under low-temperature stress. In this study, the effect of low-temperature on some physiological and biochemical parameters has been investigated using the green algae Chlamydomonas reinhardtii. The lipid peroxidation rate, amount of Rubisco protein, activities of antioxidant enzymes and gene expression of polyamine biosynthesis (odc2, and spd1), heat shock proteins (hsp70c, hsp90a, and hsp90c), and PSII repair mechanisms (psba, rep27, and tba1) were determined to understand the low-temperature response. Exogenous putrescine application significantly increased Rubisco protein concentration and catalase enzyme activities under low-temperature stress. Moreover, real-time RT-PCR results and gene expression analysis… More >

    Effects of High-Temperature Stress on Photosynthetic Characteristics and Antioxidant Enzyme System of Paeonia ostii

    Xiaoxiao Wang1, Ziwen Fang1, Daqiu Zhao1, Jun Tao1,2,*
    Phyton-International Journal of Experimental Botany, Vol.91, No.3, pp. 599-615, 2022, DOI:10.32604/phyton.2022.017881
    Abstract

    Paeonia ostii is an economically important oil crop, which has been widely cultivated in the middle and lower reaches of the Yangtze River in China in recent years. Although P. ostii is highly adaptable to the environment, the prolonged high summer temperature in this region severely inhibits its growth, which adversely affects seed yield and quality. In this study, P. ostii plants were subjected to 20°C/15°C (day/night) and 40°C/35°C (day/night) temperatures for 15 days. The changes in physiological and biochemical indicators of P. ostii under high-temperature stress were initially investigated. The results showed that with the deepening of leaf etiolation,… More >

    Phyton-International Journal of Experimental Botany, Vol.91, No.3, pp. 617-632, 2022, DOI:10.32604/phyton.2022.017741
    (This article belongs to this Special Issue: Plant Ecophysiology: Recent Trends and Advancements)
    Abstract Carpinus oblongifolia is an endemic species and the extant wild populations show a fragmentation distribution in the Baohua Mountain of Jiangsu Province in eastern China. Understanding of genetic diversity plays an important role in C. oblongifolia survival and sustainable development. The wild C. oblongifolia population was artificially divided into four subpopulations according to the microhabitats, and another two subpopulations were constructed by progeny seedlings cultivated with the mature seeds. Then, the leaf buds of 80 individuals from six subpopulations were sampled to develop single nucleotide polymorphisms (SNPs) using specific-locus amplified fragment sequencing (SLAF-seq). Based on these SNPs, we aimed to… More >

    M. Rafiqul Islam1,*, M. Shahinur Islam1, Nurunnaher Akter1, Mohammed Mohi-Ud-Din2, Mohammad Golam Mostofa3,4,*
    Phyton-International Journal of Experimental Botany, Vol.91, No.3, pp. 633-649, 2022, DOI:10.32604/phyton.2022.018074
    Abstract Improvement of plant performance under drought stress is crucial to sustaining agricultural productivity. The current study investigated the ameliorative effects of foliar-applied kinetin, an adenine-type cytokinin (CK), on growth and gas exchange parameters, water relations and biochemical attributes of maize plants under drought stress. Eighteen-day-old maize plants were subjected to drought by maintaining soil moisture content at 25% field capacity for 8 days followed by foliar application of kinetin at 0, 75, 150 and 225 mg L−1 (CK0, CK75, CK150 and CK225, respectively) to the plants for two-times at the 9-day interval. Results revealed that drought stress markedly reduced stem diameter,… More >

    Phyton-International Journal of Experimental Botany, Vol.91, No.3, pp. 651-665, 2022, DOI:10.32604/phyton.2022.017633
    (This article belongs to this Special Issue: The Effect of Soil Quality Degradation on the Plant Growth, Quality and Food Safety in Subtropical Agroforestry Ecosystems)
    Abstract As a macronutrient, Phosphorus (P) takes many roles in plant growth and development. It should be significant to explore the molecular mechanism of low-phosphorus stress response of plants. Phosphate starvation response (PHR) transcription factors play important roles in response to phosphorus deficiency stress in plants. In this study, we isolated a gene related to the plant phosphorus signaling system from the acid-soil-resistant centipedegrass (Eremochloa ophiuroides [Munro] Hack.), termed EoPHR2. The subcellular localization of EoPHR2 protein was observed to be nuclear located. The expression patterns of EoPHR2 in different tissues and Al/Pi-stress conditions were analyzed by qRT-PCR, they suggested a potential… More >
