    Xiaomei Zhang, Junliang Li, Bin Liang*

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2021.014962

    Abstract Greenhouse vegetable cultivation (GVC) is an example of intensive agriculture aiming to increase crop yields by extending cultivation seasons and intensifying agricultural input. Compared with cropland, studies on the effects of farming management regimes on soil microorganisms of the GVC system are rare, and our knowledge is limited. In the present study, we assessed the impacts of different long-term fertilization regimes on soil fungal community structure changes in a greenhouse that has been applied in tomato (Solanum lycopersicum L.) cultivation for 11 consecutive years. Results showed that, when taking the non-fertilizer treatment of CK as a benchmark, both treatments of… More >

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2021.014567

    Abstract Chickpea contains high levels of protein, vitamins and minerals. Acceptable chickpea yield is the result of meeting nitrogen and phosphorus requirements. The effect of appropriately meeting such requirements reflects on growth and can easily be evaluated using growth analysis. This research determined: (a) The effect of nitrogen and phosphorus fertilization on phenology, net assimilation rate, number of green leaves, leaf area, leaf area index and leaf area duration; (b) Green chickpea yield and number of pods due to fertilization; and (c) The combination of nitrogen and phosphorus fertilization that yields the most net revenue. Nitrogen and phosphorus fertilization was evaluated;… More >

    Differential Responses of NHX1 and SOS1 Gene Expressions to Salinity in two Miscanthus sinensis Anderss. Accessions with Different Salt Tolerance

    Qian Sun1,2, Toshihiko Yamada3, Yulai Han2,*, Tetsuo Takano1,*

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2021.013805

    Abstract The lignocellulosic crop Miscanthus spp. has been identified as a good candidate for biomass production. The responses of Miscanthus sinensis Anderss. to salinity were studied to satisfy the needs for high yields in marginal areas and to avoid competition with food production. The results indicated that the relative advantages of the tolerant accession over the sensitive one under saline conditions were associated with restricted Na+ accumulation in shoots. Seedlings of two accessions (salt-tolerant ‘JM0119’ and salt-sensitive ‘JM0099’) were subjected to 0 (control), 100, 200, and 300 mM NaCl stress to better understand the salt-induced biochemical responses of genes involved in… More >

    Genome-wide Analysis of a Plant AT-rich Sequence and Zinc-binding Protein (PLATZ) in Triticum Aestivum

    Xiaohang He1, Minjie Liu2, Zhengwu Fang1, Dongfang Ma1,2,3,*, Yilin Zhou1,3,*, Junliang Yin1

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2021.012726

    Abstract Plant AT-rich sequence and zinc-binding protein (PLATZ) is a plant transcription factor that has been studied in corn. PLATZ can non-specifically bind to sequences rich in A/T bases to induce transcriptional repression. It is involved in the regulation of dehydration tolerance in seeds. In this study, we performed bioinformatics analysis to identify and characterize wheat PLATZ(TaPLATZ)genes. We identified 49 wheat PLATZ genes by searching the wheat genome by using known PLATZ gene sequences from rice, Arabidopsis, and maize. Phylogenetic analysis on PLATZ gene sequences from different species was performed. We found that PLATZs could be divided into three groups. The… More >

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2021.014858

    Abstract A field experiment was conducted to determine the effects of two commercial strains composed of mulple arbuscular mycorrhizal fungi (AMF) species on plant growth, antioxidant capacity, and medicine quality of Paris polyphylla var. yunnanensis in three subtropical soils from Wanzhou, Anshun and Baoshan in fields. The results showed that AMF inoculation enhanced the fungal colonization rate and activities of both succinate dehydrogenase and alkaline phosphatase, thereby, enhancing the mycorrhizal viability of P. polyphylla var. yunnanensis. The concentrations of photosynthetic pigments (chlorophyll a, b, a+b and carotenoids), soluble sugar, soluble protein and photosynthetic capacity were higher in AMF-inoculated plants than in… More >

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2021.014301

    Abstract The tomato (Solanum lycopersicum L.) is one of the world’s most important vegetable crops. Still, phytopathogenic bacteria affect the yield and quality of tomato cultivation, like Agrobacterium tumefeciens (At), Clavibacter michiganensis subsp. michiganensis (Cmm), Pseudomonas syringae pv. tomato (Pst), Ralstonia solanacearum (Rs), and Xanthomonas axonopodis (Xa). Synthetic chemical products are used mostly on disease plant control, but overuse generates resistance to bacterial control. This study aimed to evaluate the in vitro antibacterial activity of the ethanolic extract of Moringa oleifera Lam. leaves against At, Cmm, Pst, Rs, and Xa, as well as information about this plant species’ chemical composition. Antibacterial… More >

    Cesar B. Ramírez-López1,2, Rita Beltrán-Sánchez1, Alistair Hernández-Izquierdo1, José Luis SalvadorHernández1, Eduardo Salcedo-Pérez2, Rosa E. del Río1, Mauro M. Martínez Pacheco1,*

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2021.013775

    Abstract This study scrutinized the possibility of finding toxicant or deterrent plant metabolites against the dry wood termite Incisitermes marginipennis (Latreille). Plant deterrent agents act as repellents or antifeedants to prevent wood decay and increase its useful life. The potential of the tree Caesalpinia coriaria (Fabaceae) as a biological source of molecules with deterrent effects against the dry wood termite was assessed by a phytochemical fractionation guided by repellence and antifeedant activities. The gas chromatography-mass spectrometry analysis of the leaf essential oil showed geraniol to be one of the major components and its repellent and antifeedant effects were determined. Geraniol had… More >
