    Salt Stress Threshold in Millets: Perspective on Cultivation on Marginal Lands for Biomass

    Naveed Ul Mushtaq1, Seerat Saleem1, Aadil Rasool1, Wasifa Hafiz Shah1, Khalid Rehman Hakeem2,*, Reiaz Ul Rehman1,*

    Phyton-International Journal of Experimental Botany, Vol.90, No.1, pp. 51-64, 2021, DOI:10.32604/phyton.2020.012163


    Millets hold an immense assurance for food safety and nourishment amid ever-rising agricultural expenses and climate alterations. They are healthful, have supplementary wellbeing profit and need remarkably fewer effort overheads for crop growing. These characters draw attention to millets as a plant of preference for the humankind in the course of emergent alarm about environmental changes. Millets have the prospect to provide biomass and thus bioenergy, reduced carbon emission, carbon footprint and sustainable modern agriculture. As the rate of expansion in budding countries is increasing day by day, the scarcity of energy is a big panic

    Trichoderma-Induced Improvement in Growth, Photosynthetic Pigments, Proline, and Glutathione Levels in Cucurbita pepo Seedlings under Salt Stress

    Mona H. Soliman1, Taghreed S. Alnusaire2, Nessreen F. Abdelbaky3,4, Aisha A. M. Alayafi5, Mirza Hasanuzzaman6,*, Mohamed M. Rowezak2, Mohamed El-Esawi7, Amr Elkelish8

    Phyton-International Journal of Experimental Botany, Vol.89, No.3, pp. 473-486, 2020, DOI:10.32604/phyton.2020.08795

    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 inoculation of Trichoderma spp.… More >

    Genome-Wide Identification of the F-box Gene Family and Expression Analysis under Drought and Salt Stress in Barley

    Lantian Zhang, Siyi Wang, Yuyu Chen, Mengyuan Dong, Yunxia Fang, Xian Zhang, Tao Tong, Ziling Zhang, Junjun Zheng, Dawei Xue*, Xiaoqin Zhang*

    Phyton-International Journal of Experimental Botany, Vol.89, No.2, pp. 229-251, 2020, DOI:10.32604/phyton.2020.10022

    Abstract The F-box protein-encoding gene family plays an essential role in plant stress resistance. In present study, 126 non-redundant F-box genes were identified in barley (Hordeum vulgare L., Hv). The corresponding proteins contained 165– 887 amino acid residues and all were amphiphilic, except 5 proteins. Phylogenetic analysis of F-box protein sequences in barley and stress-related F-box protein sequences in wheat and Arabidopsis thaliana (At) was used to classify barley F-box genes are divided into 9 subfamilies (A–I). A structure-based sequence alignment demonstrated that F-box proteins were highly conserved with a total of 10 conserved motifs. In total, 124 F-box genes were… More >

    Germination of four grasses under salt stress

    Ruiz M1 y O Terenti2

    Phyton-International Journal of Experimental Botany, Vol.81, pp. 169-176, 2012, DOI:10.32604/phyton.2012.81.169

    Abstract In Argentina cultivated grasses are the livelihood of the traditional livestock systems. Actually, the introduction of pastures in arid zones is one of the major challenges for ranchers. The aim of this work was to assess the germination of four forage species: Agropyron elongatum, Antephora pubescens, Cenchrus ciliaris cv Texas and Panicum coloratum cv Klein verde under water stress and salinity. Were used solutions of NaCl, KCl, Na2SO4, K2SO4 and Mannitol as inert solute, obtaining osmotic potentials (Ψo) of -0.5, -1, -1.5 -2.0, or -2.5 MPa. Seeds were cultivated in Petri dishes on germination paper, watered with 4… More >

    Effect of mixed salt stress on malondialdehyde, proteins and antioxidant enzymes of Leymus chinensis in three leaf colors

    Zhou C1,2, CA Busso3, YG Yang2, Z Zhang4, ZW Wang1, YF Yang5, XG Han1

    Phyton-International Journal of Experimental Botany, Vol.86, pp. 205-213, 2017, DOI:10.32604/phyton.2017.86.205

    Abstract The mixed salt stress is common in nature. Salt stress always affects plant growth. Different plant species have different adaptive capacity to salty soils. Leymus chinensis is an herbaceous plant with different leaf colors. However, little research was conducted to explore the different tolerance mechanisms to salt stress among the three different leaf colour genotypes of Leymus chinensis (grey green, transitional color, yellow green). Pot experiments for Leymus chinensis in three leaf colors were conducted under mixed salt treatments in 2010. Malondialdehyde (MDA) and protein concentrations, and the activity of various antioxidant enzymes [i.e., superoxide dismutase (SOD), catalase… More >

    Responses of C:N:P stoichiometry of plants from a Hulunbuir grassland to salt stress, drought and nitrogen addition

    Wang XG1, Wuyunna1*, CA Busso2, YT Song1, FJ Zhang1, GW Huo1

    Phyton-International Journal of Experimental Botany, Vol.87, pp. 123-132, 2018, DOI:10.32604/phyton.2018.87.123

    Abstract Chemical elements, such as carbon (C), nitrogen (N) and phosphorus (P), are major limiting nutrients in arid and semiarid grasslands and their stoichiometry (C:N:P) is a very important ratio to determine. In addition, it is critical to understand how plant stoichiometry responds to multiple environmental factors at the species level. In this study, we conducted a greenhouse experiment to investigate the effects of salt stress (4 g NaCl/kg soil), drought (35% of the soil water holding capacity) and N addition (10 g N/m2), as well as their interactions, on C, N and P concentrations and C:N:P… More >
