Osmotic adjustment in cowpea plants: Interference of methods for estimating osmotic potential at full turgor
The objective of this study was to consider the osmotic adjustment comparing results obtained by pressure-volume (P–V) curves and osmometry. The experiment was conducted in a randomized block design, with six salt water concentrations 0, 20, 40, 60, 80, and 100 mmol L−1 of NaCl in a Fluvisol. The osmotic adjustment found through osmometry were lower than those found through P–V curves. The apoplastic water fraction of the cowpea had a dilution effect, denoting overestimation of the osmotic potential by the methodology based on osmometry. This may be the source of the different interpretations of osmot...

Tartary buckwheat transcription factor FtbZIP83 improves the drought/salt tolerance of Arabidopsis via an ABA-mediated pathway
In this study, a gene encoding an AREB/ABF, designated FtbZIP83, was first isolated from Tartary buckwheat. Expression analysis in Tartary buckwheat indicated that FtbZIP83 was significantly induced by abscisic acid (ABA), NaCl and polyethylene glycol (PEG). The overexpression of FtbZIP83 in Arabidopsis resulted in increased drought/salt tolerance, which was attributed not only to higher proline (Pro) contents and antioxidant enzyme activity in transgenic lines compared with controls but also to the lower reactive oxygen species (ROS) accumulation and malondialdehyde (MDA) content. In addition, we found that FtbZIP83 was a...

Reyes-DíazAbstractWe evaluated whether phosphorus (P) ameliorates manganese (Mn) excess harmful effects on photosynthetic performance, growth, oxidative stress, and antioxidants in ryegrass. Two perennial ryegrass genotypes, Banquet-II as Mn-resistant and One-50 as Mn-sensitive genotype, were growth under hydroponic conditions subjected to increased P (25, 50, 100, 200 and 400 μM), excess (750 μM) and suffic...

Metabolic features underlying the response of sweet cherry fruit to postharvest UV-C irradiation
Publication date: Available online 19 September 2019Source: Plant Physiology and BiochemistryAuthor(s): Michail Michailidis, Evangelos Karagiannis, Chrysanthi Polychroniadou, Georgia Tanou, Katerina Karamanoli, Athanassios MolassiotisAbstractThe impact of ultraviolet-C (UV–C) irradiation on sweet cherry fruit was studied. Following harvest, fruits (cv. Sweetheart) were exposed to different doses of UV-C (0, 1.2, 3.0 or 6.0 kJ m−2) and then cold stored (0 °C) for 10 days. Treatments with UV-C delayed most ripening features and reduced pitting symptoms, particularly following prolonged UV-C application....

Heteromorphic seeds of coastal halophytes Arthrocnemum macrostachyum and A. indicum display differential patterns of hydrogen peroxide accumulation, lipid peroxidation and antioxidant activities under increasing salinity
This study elucidates changes in levels of hydrogen peroxide (H2O2), malondialdehyde (MDA) and enzymatic antioxidants in heteromorphic seeds of contrasting congeneric halophytes Arthrocnemum macrostachyum (C3 perennial) and A. indicum (C4 perennial) during germination under increasing salinity. There was no dormancy in A. macrostachyum (black and brown) and A. indicum (large and small) seeds. Seeds of A. macrostachyum displayed greater salinity tolerance compared to A. indicum seeds. Under non-saline conditions, large A. indicum seeds and brown A. macrostachyum seeds showed slightly higher germination than their respective...

Effects of soil rewatering on mesophyll and stomatal conductance and the associated mechanisms involving leaf anatomy and some physiological activities in Manchurian ash and Mongolian oak in the Changbai Mountains
Publication date: Available online 19 September 2019Source: Plant Physiology and BiochemistryAuthor(s): Kai Zhu, Fenghui Yuan, Anzhi Wang, Hong Yang, Dexin Guan, Changjie Jin, Hongxia Zhang, Yushu Zhang, Jiabing WuAbstractThe recoveries of mesophyll (gm) and stomatal conductance to CO2 (gsc) after soil rewatering have received considerable attention in recent years, but the recovery mechanisms involving leaf anatomy and physiological activities are poorly understood. Moreover, it is also unclear whether leaf gas-phase conductance (gias) or liquid-phase conductance (gliq) is the main factor promoting gm recovery. By simulta...

Iodine biofortification through expression of HMT, SAMT and S3H genes in Solanum lycopersicum L.
Publication date: Available online 18 September 2019Source: Plant Physiology and BiochemistryAuthor(s): Mariya Halka, Sylwester Smoleń, Małgorzata Czernicka, Magdalena Klimek-Chodacka, Joanna Pitala, Krzysztof TutajAbstractThe uptake process and physiological reaction of plants to aromatic iodine compounds have not yet been documented. The aim of this research was to compare uptake by tomato plants of KI and KIO3, as well as of organic iodine compounds – 5-ISA (5-iodosalicylic acid), 3,5-diISA (3,5-diiodosalicylic acid), 2-IBeA (2-iodobenzoic acid), 4-IBeA (4-iodobenzoic acid) and 2,3,5-triIBeA (2,3,5-triiodobenzoi...

Grape phylloxera (D. vitifoliae) manipulates SA/JA concentrations and signaling pathways in root galls of Vitis spp
This study aims to investigate whether host defensive SA/JA signalling pathways are affected during D. vitifoliae infestation. We hypothesize that the JA signalling pathway is induced during larval probing (14 hai). Compatible root gall formation (24 hai −14 dai) involves the reduction of the JA, but the induction of the SA signaling pathway. T5C (V. riparia x V. berlandieri) cuttings are infested with a D. vitifoliae single founder lineage (biotype C). Phytohormone quantification (HPLC-MS) and transcriptional alterations of JA/SA marker genes (qRT-PCR) are determined in root tissues from larval probing (14 hai) unti...
