TL;DR: In this paper, a pot experiment was conducted to assess how an arbuscular mycorrhizal fungus, Funneliformis mosseae, affects root polyamines (PAs) homeostasis, activities and gene expressions of PA-related synthesizing and degrading enzymes, hydrogen peroxide (H2O2, a PA metabolite) production, and antioxidant enzyme gene expressions in trifoliate orange (Poncirus trifoliata) exposed to drought stress.

TL;DR: The role of exogenous application of SA in regulating diverse physiological and biochemical processes in healthy and stressed plants is evaluated and the cross talk of SA with other phytohormones and polyamines under normal and stressed conditions is discussed.

TL;DR: In this paper, the effect of mycorrhizal inoculation on the growth performance of tobacco (Nicotiana tabacum L. variety Yunyan 87) under drought stress was investigated.

TL;DR: The results suggest that SlWRKY81 acts as a negative regulator of stomatal closure by suppressing SlRBOH1-derived H2O2 accumulation, which attenuates plant tolerance to drought.

TL;DR: The review emphasized the multiple roles of melatonin against environmental stresses in horticultural crops along with future research directions, which could be useful for improving the eco-friendly crop production and ensure food safety.

TL;DR: The plasticity of photosynthesis and the high antioxidant capacity of O. africana appear to contribute to its tolerance to drought, with increasing drought stress severity.

TL;DR: It is shown for the first time a long-term drought stress memory in a grass species, lasting over several weeks, that drought priming enhances the activity of anti-oxidative enzymes, key for depressing oxidative damage and for improving tolerance to subsequent drought stress in A. pratensis.

TL;DR: This paper explored the role of Tre in tomato cold tolerance and evaluated whether hydrogen peroxide (H2O2) and nitric oxide (NO) in Tre-induced cold stress tolerance in plants.

TL;DR: In this article, the role of trichoderma harzianum (TH) in improving the physiological, biochemical, hormonal, and molecular parameters of tomato seedlings grown under waterlogging (WL, for 14 and 28 days).

TL;DR: Systematizing the observed changes in terpene quantity and quality in the three most important forest-forming conifer genera of European temperate climate zone emphasizes a complex function of these interesting compounds in trees including interplant signaling in forest communities.

TL;DR: A step forward is taken to develop flood resilient crop plants by exploiting the knowledge of ethylene biology and functions by assessing the ethylene functions under flooding stress based on available evidences.

TL;DR: In this article, the influence of sample preparation and measuring methods on the obtained ATR-FTIR spectra of angiosperms (flowering plants), which were measured by the same plant, was investigated.

TL;DR: In this paper, the toxicity of hexavalent chromium (Cr) on maize (Zea mays L.) seedlings was assessed and three different levels of Cr stress were imposed and maize seedling growth performances were monitored at 2d and 4d.

TL;DR: In this paper, the authors investigated the effect of monochromatic light during plant photomorphogenesis from seed imbibition up to seedling development and found that blue wavelengths are more critical than red ones for the functionality of the photosynthetic apparatus.

TL;DR: Overall, all genotypes suppressed waterlogging stress with distinct mechanisms, and PELBR10-6000 surpassed control plant levels of CO2 assimilation rate and readily responded to the energy lack induced by hypoxia by activating the fermentative enzymes and alanine aminotransferase.

TL;DR: In this paper, the authors have focused on NRAMP (Natural Resistance-Associated Macrophage Protein) family proteins transporters as potential candidates conferring superior hyperaccumulating ability in this species and undertaken its functional characterization.

TL;DR: In this paper, the authors provide an up-to-date description of advanced nanoparticles and polymers applied at plant and seed level, covering technical, biological and socioeconomical aspects of this promising approach.

TL;DR: In this paper, the role of anthocyanin accumulation in poinsettia leaves exposed to photo-oxidative stress was evaluated by comparing green and reddish leaves, co-occurring in the Euphorbia pulcherrima.

TL;DR: Improved growth under elevated [CO2] was more evident under drought than under full irrigation, and was unlikely to have been associated with global changes on hormonal pools, but rather with shifts on carbon fluxes.

TL;DR: It is reckons that new insights and focus research are required for developing resilient plant species towards low temperature for achieving agricultural sustainability and ensuring food security in the coming years.

TL;DR: It is suggested that the lower reduction in vessel density, vessel area, and vessel diameter in the Fuji cultivar under waterlogging are major factors that improve plant–water relations and photosynthetic performance, which in turn determine the leaf morphological characteristics and vegetative growth under prolonged waterlogged.

TL;DR: In this article, the projected impact of global climatic change on useful plants across the spectrum of plant domestication is synthesized, and the demographic, spatial, ecophysiological, chemical, functional, evolutionary and cultural traits that are likely to characterise useful plants and their resilience in the next century are illustrated.

TL;DR: The potential role of lncRNAs in B. juncea in response to both heat and drought stress is highlighted and can help elucidate the mechanism of tolerance to these abiotic stress conditions in the oil seed crop.

TL;DR: Findings revealed that DcDREB1A was involved in the regulation of plant tolerance to drought by regulating the activities of reactive oxygen species (ROS)-scavenging enzymes (SOD and POD) to maintain ROS homeostasis in cells, reducing stomata apertures and density.

TL;DR: In this article, the water absorbent hydrogels from synthetic polymers can retain moisture from irrigation or rainfall and release it in response to crop water demands, but have a limited functional lifespan and may release byproducts that are harmful to plants or pollute the soil environment.

TL;DR: In this article, a member of the WRKY transcription factor family, which is involved in many abiotic stress responses, was cloned from Populus trichocarpa (clone ‘Nisqually-1′) and expressed in senescent leaves and could be induced by both dehydration and treatment with salicylic acid (SA).

TL;DR: In this article, the effects of soil water content and heat conditions on specific leaf area (SLA) dynamics have been studied, and the results imply that there is a trade-off mechanism between soil water and heat condition in shaping the dynamic characteristics of SLA.
