Lead Uptake, Toxicity, and Detoxification in Plants [PDF]

open access: yes, 2011
Lead has gained considerable attention as a persistent toxic pollutant of concern, partly because it has been prominent in the debate concerning the growing anthropogenic pressure on the environment.

Influence of salicylic acid on phytochelatin synthesis in Zea mays during Cd stress [PDF]

open access: yes, 2013
: Presoaking maize (Zea mays) seeds in salicylic acid (SA) reduces damage caused by cadmium. In the present work the possible role of phytochelatins (PCs) in SA-mediated protection against Cd toxicity was investigated. Seeds were presoaked in 0.5 mM SA,

Exogenous Melatonin Delays Dark-Induced Grape Leaf Senescence by Regulation of Antioxidant System and Senescence Associated Genes (SAGs)

open access: yesPlants, 2019
Leaf senescence is a developmentally programmed and degenerative process which comprises the last stage of the life cycle of leaves. In order to understand the melatonin effect on grapevine leaf senescence, the dark treatment on detached leaves of Vitis ...

Responses of wheat and barley to Acacia saligna leaf and stem extracts: influence on growth and ascorbate-glutathione cycle

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2022
The present study aimed to study the effect of dry leaf and stem leachates of Acacia saligna on wheat’s growth and enzyme functioning (Triticum aestivum) and barley (Hordeum vulgare). Leaf leachates (LL) and stem leachates (SL) of A.

Exogenous Zeaxanthin Alleviates Low Temperature Combined with Low Light Induced Photosynthesis Inhibition and Oxidative Stress in Pepper (Capsicum annuum L.) Plants

open access: yesCurrent Issues in Molecular Biology, 2022
Low temperature combined with low light (LL) affects crop production, especially the yield and quality of peppers, in northwest China during the winter and spring seasons. Zeaxanthin (Z) is a known lipid protectant and active oxygen scavenger.

Characteristics of the tomato chromoplast revealed by proteomic analysis [PDF]

open access: yes, 2010
Chromoplasts are non-photosynthetic specialized plastids that are important in ripening tomato fruit (Solanum lycopersicum) since, among other functions, they are the site of accumulation of coloured compounds.

Studies on the hyperplasia ('regeneration') of the rat liver following partial hepatectomy. Changes in lipid peroxidation and general biochemical aspects [PDF]

open access: yes, 1990
Using the experimental model of partial hepatectomy in the rat, we have examined the relationship between cell division and lipid peroxidation activity. In rats entrained to a regime of 12 h light/12 h dark and with a fixed 8 h feeding period in the dark

Role of Glutathione-Ascorbate Cycle and Photosynthetic Electronic Transfer in Alternative Oxidase-Manipulated Waterlogging Tolerance in Watermelon Seedlings

open access: yesHorticulturae, 2021
Alternative oxidase (AOX) has been documented to mitigate the oxidative stress caused by abiotic stresses. However, it remains unknown how AOX regulates the antioxidant system and photosynthesis under waterlogging.

Antioxidant Systems are Regulated by Nitric Oxide-Mediated Post-translational Modifications (NO-PTMs) [PDF]

open access: yes, 2016
Nitric oxide (NO) is a biological messenger that orchestrates a plethora of plant functions, mainly through post-translational modifications (PTMs) such as S-nitrosylation or tyrosine nitration.

Novel insight into functions of ascorbate peroxidase in higher plants: More than a simple antioxidant enzyme

open access: yesRedox Biology, 2023
As plants are sessile organisms, they are inevitably exposed to a variety of environmental stimuli that trigger rapid changes in the generation and disposal of reactive oxygen species such as hydrogen peroxide (H2O2).
