Silicon Supplementation Induces Physiological and Biochemical Changes That Assist Lettuce Salinity Tolerance
Hozano de Souza Lemos Neto,Marcelo de Almeida Guimarães,Rosilene Oliveira Mesquita,Wallace Edelky Sousa Freitas,Alexandre Bosco de Oliveira,Nildo da Silva Dias,Enéas Gomes-Filho +6 more
TL;DR: In this article, the effects of silicon on the physiological and biochemical characteristics of vegetables under salt stress were evaluated. But the limited accumulation of silicon in lettuce leaf tissues has not been sufficient to induce physiological responses that lead to increased production under high-salinity conditions.

Overexpression of a Voltage-Dependent Anion-Selective Channel (VDAC) Protein-Encoding Gene, MsVDAC, from Medicago sativa Confers Cold and Drought Tolerance to Transgenic Tobacco.
TL;DR: In this paper, a novel voltage-dependent anion channel (VDAC) gene was identified from alfalfa (Medicago sativa L) roots and its expression was highest in alalfa roots and was induced in response to cold, drought and salt treatment.

Proteome analysis of Pueraria mirifica tubers collected in different seasons
Jutarmas Jungsukcharoen,Daranee Chokchaichamnankit,Chantragan Srisomsap,Wichai Cherdshewasart,Polkit Sangvanich +4 more
TL;DR: Pueraria mirifica-derived tuberous powder has been long-term consumed in Thailand as female hormone-replacement traditional remedies and the protein profiles of tubers collected in different seasons were evaluated, finding proteins found to be differentially expressed with respect to harvest season.

The effects of silver and arsenic on antioxidant system in Lemna paucicostata: Different effects on glutathione system
TL;DR: In this paper, the effects of Ag+ and As3+ exposure on the growth rate of Lemna paucicostata with IC50 values of 0.101 ± 0.004 mg/mL and 0.753± 0.127mg/mL, respectively, were found.

Oxidant and antioxidant signalling in plants: a re-evaluation of the concept of oxidative stress in a physiological context
Christine H. Foyer,Graham Noctor +1 more
TL;DR: It is proposed that the oxidative stress syndrome would be more usefully described as 'oxidative signalling', that is, an important and critical function associated with the mechanisms by which plant cells sense the environment and make appropriate adjustments to gene expression, metabolism and physiology.

Glutathione in plants: an integrated overview.
Graham Noctor,Amna Mhamdi,Sejir Chaouch,Yi Han,Jenny Neukermans,Belén Márquez-García,Guillaume Queval,Christine H. Foyer +7 more
TL;DR: How alterations in glutathione status, such as those observed during stress, may participate in signal transduction cascades are discussed and how these alterations are integrated to fine-tune photorespiratory and respiratory metabolism and to modulate phytohormone signalling pathways.
Journal ArticleDOI
Biotechnological approach of improving plant salt tolerance using antioxidants as markers.
TL;DR: The role of different antioxidants as potential selection criteria for improving plant salt tolerance has been critically discussed and the potential of this approach in counteracting stress-induced oxidative stress has been discussed at length in this review.
