    The Function of GABA in Plant Cell Growth, Development and Stress Response

    Yue Jin1, Lulu Zhi1, Xin Tang1, Yilin Chen1, John T. Hancock2, Xiangyang Hu1,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.8, pp. 2211-2225, 2023, DOI:10.32604/phyton.2023.026595

    Abstract Gamma-aminobutyric acid (GABA) is a ubiquitous four-carbon non-protein amino acid that is involved in various physiological processes of plant growth and development, such as root architecture, stem elongation, leaf senescence, pollen tube growth, fruit ripening, and seed germination. GABA is also related to plant stress responses, such as drought, salt, cold, and heat stresses. Regulation of GABA in plant stress responses is complex and involves multiple signaling pathways, including calcium and hormone signaling. This paper systematically reviews the synthesis, metabolic pathways and regulatory role of GABA in plants, which will provide new insights into the understanding of plant growth and… More >

    Phyton-International Journal of Experimental Botany, Vol.92, No.7, pp. 1955-1974, 2023, DOI:10.32604/phyton.2023.028583

    Abstract The extensive use of nanoparticles (NPs) in diverse applications causes their localization to aquatic habitats, affecting the metabolic products of primary producers in aquatic ecosystems, such as algae. Synthesized calcium oxide nanoparticles (CaO NPs) are of the scarcely studied NPs. Thus, the current work proposed that the exposure to CaO NPs may instigate metabolic pathway to be higher than that of normally growing algae, and positively stimulate algal biomass. In this respect, this research was undertaken to study the exposure effect of CaO NPs (0, 20, 40, 60, 80, and 100 µg mL−1 ) on the growth, photosynthesis, respiration, oxidative… More >

    Journal of Renewable Materials, Vol.11, No.6, pp. 2665-2678, 2023, DOI:10.32604/jrm.2023.027441

    Abstract Heat-treated wood has good dimensional stability, durability, and color, but its susceptibility to fungal growth affects its commercial value. In this study, lumber harvested from mature Masson’s pine (Pinus massoniana Lamb.) was vacuum impregnated with a basic copper salt solution (copper hydroxide, diethanolamine, and polyethylene glycol 200) prior to heat-treatment at 220°C for 3 h. Antifungal properties, surface chemistry, crystal structure and sugar contents were tested, compared with heat treatment alone. The results showed that the samples treated by heating without copper salt treatment showed poor suppression of fungal growth, the copper-impregnated heat-treated wood suppressed (100%) the growth of Botryodiplodia theobromaeMore >

    Abstract

    Micronutrient nanoparticles (NPs) are currently an option for chemical fertilization and biostimulation in crops. However, there is little information on the phytotoxic or biostimulatory effects of NPs at low concentrations of some elements, such as Zn. In this study, the effect of low concentrations of Zn oxide (ZnO) NPs on germination, growth variables, and nutritional attributes of lettuce (Lactuca sativa L.) was evaluated in comparison to Zn sulfate. Romaine lettuce seeds were treated with ZnSO4-- × 7H2O and ZnO NPs at Zn molar concentrations of 1 × 10−3, 5 × 10−3, 1 × 10−4, 5 × 10−4, 1… More >
