    Abstract Sorghum (Sorghum bicolor L. Moench) is an essential food crop for more than 750 million people in tropical and sub-tropical dry climates of Africa, India, and Latin America. The domestic sorghum market in Indonesia is still limited to the eastern region (East Nusa Tenggara, West Nusa Tenggara, Java, and South Sulawesi). Therefore, it is crucial to carry out sorghum research on drylands. This research aimed to investigate the effect of sorghum genotype and planting distance and their interaction toward growth and sorghum’s productivity in the Gunungkidul dryland, Yogyakarta, Indonesia. In addition, the farm business analysis, including… More >

    Abstract The xylem undergoes physiological changes in response to various environmental conditions during the process of plant growth. To understand these physiological changes, it is extremely important to observe the transport of xylem. In this study, the distribution and structure of vascular bundle in Lilium lancifolium were observed using the method of semithin section. Methods for introducing a fluorescent tracer into the xylem of the stems were evaluated. Then, the transport rule of 5(6)-Carboxyfluorescein diacetate (CFDA) in the xylem of the stem of L. lancifolium was studied by fluorescence dye in live cells tracer technology.

    Abstract Populus trinervis is native to China and plays an irreplaceable role in maintaining the ecological balance of boreal and temperate forests. P. trinervis mainly grows in high-altitude areas. At present, there are limited studies on the response of P. trinervis to different light qualities, so it is necessary to investigate the photosynthetic physiological changes of P. trinervis in different light environments. In our study, P. trinervis was grown for 8 months under light filtered by three different colored films. The three treatments were blue film, green film, and white plastic film. The effects of blue (B), green (G), and white… More >

    ShCTR1 Interacts with ShRBOH1 to Positively Regulate Aerenchyma Formation in Saussurea inversa through ROS Mediation

    Wubin Dai1, Xiuting Ju1,2, Guomin Shi1,2, Jialei Guo3,4, Tao He3,4,*
    Phyton-International Journal of Experimental Botany, DOI:10.32604/phyton.2024.050066
    Abstract Saussurea inversa is one of the Tibetan medicine with developed aerenchyma. In this study, we investigated the function of the ShCTR1 gene related to the formation of aerenchyma. The study of the occurrence and formation of aerenchyma in S. inversa has certain theoretical significance in revealing the special mechanism of alpine plants adapting to the environment. The results of yeast two-hybrid experiments showed that S. inversa ShCTR1 interacted with the ShRBOH1, which is a key producer of reactive oxygen species (ROS), and it was hypothesized that ShCTR1 regulation of aerenchyma formation in S. inversa mainly mediated by ROS. Aerenchyma induction and… More >

    (This article belongs to the Special Issue: Biofertilizers and Nano Fertilizers as Tools to Increase Agriculture Resilience and Sustainability)
    Abstract Beans contain a wide range of vitamins, proteins, calcium, and zinc which make them an important food source for many countries. To meet the demand for bean production worldwide, large amounts of fertilizers and pesticides are used. However, the cost of production and environmental impact increases. To produce food sustainably, the use of beneficial nutrients such as silicon as a biostimulant has been proposed. However, information about the effect of different sources of silicon on the metabolism of bean plants is scarce. Bean plants cv. Strike were grown in pots for 60 days and the… More >

    Abstract Trypsin, a novel superoxide scavenger, significantly enhances the storage quality of Hylocereus undatus (H. undatus). To elucidate the preservation mechanism of trypsin on H. undatus, a widely targeted metabolomic analysis, and transcriptomics analysis were conducted. Firstly, a total of 453 metabolites were identified, with organic acids and their derivatives constituting the largest proportion (25%). Amino acids and their metabolites, prominent among organic acids, were further analyzed. Among them, 73 metabolites were associated with amino acids, and 37 exhibited significant differences. The most enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway was arginine biosynthesis (map00220), with polyamine metabolites… More >

    Phyton-International Journal of Experimental Botany, DOI:10.32604/phyton.2024.048192
    Abstract The fruits of Amomum tsao-ko (Cao-Guo) were documented in Chinese Pharmacopoeia for the treatment of abdominal pain, vomiting, and plague. In our previous study, a series of diarylheptanes and flavonoids with α-glucosidase and protein tyrosine phosphatase 1B (PTP1B) inhibitory activity have been reported from the middle-polarity part of A. tsao-ko, whereas the antidiabetic potency of the low-polarity constituents is still unclear. In this study, three new hydroxytetradecenals, (2E, 4E, 8Z, 11Z)-6R-hydroxytetradeca-2,4,8,11-tetraenal (1), (2E, 4E, 8Z)-6R-hydroxytetradeca-2,4,8-trienal (2) and (2E, 4E)-6R-hydroxytetradeca-2,4-dienal (3) were obtained from the volatile oils of A. tsao-ko. The structures of compounds 1–3 were determined using spectroscopic data involving 1D and 2D nuclear magnetic More >

    (This article belongs to the Special Issue: Microbial Biotechnology Applications on Plant Performance and Physiology for Sustainable Production )
    Abstract Garden pea productivity and qualities are hampered in zinc (Zn), boron (B), and molybdenum (Mo) deficient soil. Thus, the combination of micronutrients (i.e., Zn, B, and Mo) and rhizobium is necessary to increase the productivity and quality of garden peas, since this management for garden peas is neglected in Bangladesh. Therefore, the present study was made to assess the effectiveness of rhizobium inoculant singly or in combination with the micronutrients (i.e., Zn, B, and Mo) on growth, yield, nutrient uptake, and quality of garden peas. Treatments were: T = Control, T = Rhizobium inoculation at 50… More >

    Chengxu Qian1, Qiangwen Chen1,2, Leiyu Jiang1, Xiaoyan Yang3, Shen Rao4, Weiwei Zhang1, Feng Xu1,*
    Phyton-International Journal of Experimental Botany, DOI:10.32604/phyton.2024.050893
    (This article belongs to the Special Issue: Abiotic Stress Impacts on Plant Physiology and Their Alleviation)
    Abstract The objective of this study was to explain the physiological mechanisms through which Na2SeO3 mitigates the growth and developmental inhibition of pakchoi under HgCl2 stress. The results showed that treatment with HgCl2 (40 mg L−1 ) led to reduced biomass, dwarfing, root shortening, and root tip necrosis in pakchoi. Compared to control (CK), the activities of superoxide dismutase (SOD) and peroxidase (POD) in Hg treatment increased, and the content of malondialdehyde (MDA) also dramatically increased, which negatively impacted the growth of pakchoi. Low concentrations of Na2SeO3 (0.2 mg L−1 ) significantly increased the content of soluble sugars compared… More >
