Abstract Plants exposed to drought not only have cope with a shortage of water, but also simultaneous decrease in nutrient availability. In this greenhouse experiment, the responses antioxidants and key metabolites 2 or 4 days water limitation immediately prior harvest were compared effect continued supply lettuce leaves. Water led faster increase stress intensity than limitation. While moderate slight antioxidant compounds studied, there was concomitant sharp starch content. Under limitation, an content ascorbic acid, proportion reduced acid phenolic compounds, flavonoids, soluble sugars observed mild phase stress. These results suggest that reducing availability shortly before could be suitable means improving nutritional value crops through cultivation practices as opposed breeding.

<abstract><p>Due to factors such as climate change, natural disasters, and deforestation, most measurement processes initial data may have errors. Therefore, models with imprecise parameters are more realistic. This paper constructed a new predator-prey model an interval biological coefficient by using the number parameter. First, stability of solution fractional order without diffusion term Hopf bifurcation $ \alpha were analyzed theoretically. Then, taking prey key parameter, Turing at equilibrium point was discussed. The amplitude equation near threshold instability given weak nonlinear analysis method, different mode selections classified equation. Finally, we numerically proved that dispersal rate population suppressed spatiotemporal chaos model.</p></abstract>

Waterlogging stress leads to a reduction in the oxygen level around root system (hypoxia). It can be caused by poor air exchange flooded or compacted soil non-aerated medium. Such causes numerous morphological, physiological and biochemical changes. The present study aimed specify hypoxia-influenced modifications of catalytic subunits PP2A (PP2A-C) parallel processes tomato cultivated hydroponics. analysis included ROS detection, photosynthetic apparatus efficiency, expression PP2A-C subunit protein level, PP2A-like activity, nitrogen metabolism soluble sugars. Analyses were carried out separately for leaves roots. In leaves, there was decrease (52%) total response hypoxia system, but no significant changes PP2A-related activity found. roots, more than six-fold increase this accompanied doubling activity. applied increased nitrate reductase levels free amino acids. photosynthesis intensity noticed case stressed plants. These results show that are differentially modulated waterlogging conditions an organ-dependent way.

Abstract Within the framework of studies plants as cognitive organisms, there is a hypothesis that plant processes are not enclosed within their bodies but extend to environment. The extended cognition (EPC) suggests when modify environment around them through release volatile organic compounds (VOCs), root exudates, and sustenance mycorrhizal networks, they sensorial apparatus externalize part information-processing system. As result, can no longer be seen an isolated organism easily distinguishable from its milieu. In this article, we discuss implications understanding organisms assess four test cases corroborate EPC hypothesis, one for each possible channel discussed here. We conclude new approach redefine how understand may also fruitful source inspiration develop techniques in agriculture by enhancing external elements cognition.

Phytophagous mites are herbivores that feed on various economically important plants, such as soybean [Glycine max (L.) Merril]. Thus, our objective is to evaluate the oxidative stress stage of plants infested by Tetranychus ludeni Zacher. Leaflets from three trifoliate leaves were pooled form composite samples for each exposure time and evaluated at following evaluation times: 0 h, 20 min, 6 12 24 48 h. In initial phase infestation (20 min), an burst was observed, represented prominent hydrogen peroxide accumulation rather than superoxide radicals. This occurred in parallel a strong increase antioxidant activities catalase, ascorbate peroxidase, glutathione S-transferase, but not dismutase. These changes likely reflected enhanced activation signaling pathways involved response. After this phase, min decrease S-transferases activities, despite levels remaining significantly elevated, along with marked transient reduced content proline. Interestingly, dismutase activity increased after h lipid peroxidation, whereas remained elevated until infestation. By final evaluation, infestation, some redox indicators altered relation control state moderate stress. unprecedented way, data suggest T. triggered response plants. findings highlight proper monitoring management can reduce economic losses without resorting aggressive chemical interventions.
