    Abstract Ganoderma is a genus of medicinally and economically important mushrooms in the family Ganodermataceae. Ganoderma species are popular medicinal mushrooms and their health benefits are well-documented. Ganoderma is a cosmopolitan genus that is widely distributed in both tropical and temperate regions. This genus is characterized by its unique laccate or non-laccate species with double-walled basidiospores. Here, we report on eight collections of G. gibbosum collected during surveys in Kunming, Yunnan Province, China. The specimens are described and illustrated based on macro- and micro-morphological characteristics. Total DNA of the eight G. gibbosum strains were extracted using the Biospin Fungal Extraction Kit… More >

    Alhan Sariyev1, Celaleddin Barutcular2,*, Mert Acar1, Akbar Hossain3, Ayman EL Sabagh2,4,5,*

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2020.09142

    Abstract Maize being sub-tropical crop is sensitive to water deficit during the early growth stages; particularly clay-rich soil, due to the compaction of the soil. It is well-documented that potential sub-surface drip irrigation (SDI) (Full irrigation; SDIFull (100% field capacity (FC)), Deficit irrigation; SDIDeficit (70% FC)) improves water use efficiency, which leads to increased crop productivity; since it has a constraint that SDI excludes soil air around the root-zone during irrigation events, which alter the root function and crop performance. Additionally, in clayrich soils, the root system of plants generally suffers the limitation of oxygen, particularly the temporal hypoxia, and occasionally… More >

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2020.09720

    Abstract We isolated an interesting fungus from dead leaves of Magnolia liliifera collected from Chiang Mai, Thailand. The novel strain is related to Plectosphaerellaceae based on the morphology of its asexual morph and the analysis of sequence data. Phylogenetic analyses using a combined gene analysis of LSU and ITS sequence data showed that this strain is clustered in the same clade with Furcasterigmium furcatum with high statistical support. The new strains produced the asexual morph in culture which is morphologically similar to F. furcatum. Thus, we identified this strain as the sexual morph of F. furcatum. This is the first record… More >

    Abstract Salt stress is one of the major abiotic stress in plants. However, traditional approaches are not always efficient in conferring salt tolerance. Experiments were conducted to understand the role of Trichoderma spp. (T. harzianum and T. viride) in growth, chlorophyll (Chl) synthesis, and proline accumulation of C. pepo exposed to salinity stress. There were three salt stress (50, 100, and 150 mM NaCl) lavels and three different Trichoderma inoculation viz. T. harzianum, T. viride, and T. harzianum + T. viride. Salt stress significantly declined the growth in terms of the shoot and root lengths; however, it was improved by the… More >

    Alterations in Growth and Yield of Camelina Induced by Different Planting Densities under Water Deficit Stress

    Ejaz Ahmad Waraich1,*, Zeeshan Ahmed2,3, Zahoor Ahmad4, Rashid Ahmad1, Murat Erman5, Fatih Cig5, Ayman El Sabagh5,6

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2020.08734

    Abstract Camelina (Camelina sativa L.) is famous for its oil quality and unique fatty acid pattern. Growth and yield of crops reduced under water deficit conditions. Environmental threat such as drought or water deficit condition is the emerging problem which creates the negative impact on the growth of plants. Based upon the current situation a pot study was performed in rain out-shelter to explore the effect of different plant densities (15, 10 and 5 plants per pot) on growth and seed yield of two camelina genotypes under normal (100% WHC) and water deficit (60% WHC) conditions by using completely randomized design… More >

    Abstract Increased urbanization and industrialization have greatly contributed to the emission of higher amount of heavy metals such as cadmium, nickel, and lead into the environment. These metals are non-biodegradable and toxic, causing much effects on plants and by extension to animals and humans, which have become a major global concern. The inherent ability of plants to resist heavy metal toxicity seems to be the most sustainable and cost-effective strategy. Castor plant is widely studied due to its tolerance to the effects of heavy metal contaminated soils, owing to its large biomass content and high accumulating capacity. Castor plants to some… More >

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2020.09144

    Abstract The research was conducted to investigate comparative oxidative damage including probable protective roles of antioxidant and glyoxalase systems in rice (Oryza sativa L.) seedlings under salinity stress. Seedlings of two rice genotypes: Pokkali (tolerant) and BRRI dhan28 (sensitive) were subjected to 8 dSm−1 salinity stress for seven days in a hydroponic system. We observed significant variation between Pokkali and BRRI dhan28 in phenotypic, biochemical and molecular level under salinity stress. Carotenoid content, ion homeostasis, antioxidant enzymes, ascorbate and glutathione redox system and proline accumulation may help Pokkali to develop defense system during salinity stress. However, the activity antioxidant enzymes particularly… More >
