storage conditions; acidity; carbon dioxide; canopy; ethylene; fruits; total soluble solids; relative humidity; mangoes; ethylene production; cell respiration; fruit quality; carbon; maturity stage; trees; ripening; fruit composition; temperature
Abstract:
... Ripening of climacteric fruits is associated with pronounced changes in fruit gas composition caused by a concomitant rise in respiration and ethylene production. There is a discrepancy in the literature since some authors reported that changes in fruit gas compositions differ in attached and detached fruits. This study presents for the first time an overview of pre- and post-harvest factors that ...

Abstract:
... Owing to a weak availability in soil, plants have developed numerous morphological, physiological and biochemical adaptations to acquire phosphate (Pi). Identification and characterisation of key genes involved in the initial steps of Pi-signalling might provide clues about the regulation of the complex Pi deficiency adaptation mechanism. A two-dimensional gel electrophoresis approach was performe ...

Abstract:
... Managing fruit quality is complex because many different attributes have to be taken into account, which are themselves subjected to spatial and temporal variations. Heterogeneous fruit quality has been assumed to be partly related to temperature and maturity gradients within the fruit.To test this assumption, we measured the spatial variability of certain mango fruit quality traits: colour of the ...

(an endemic Fabaceae) and Eucalyptus globulus Labill. (used as a Myrtaceae plant host model). The aim of the study was to analyze the growth of symbiotic ECM plants growing on the ultramafic substrate that is characterized b ...

Abstract:
... Perception of elicitors triggers plant defense responses via various early signal transduction pathways. Methyl jasmonate (MeJA) stimulates defense responses in grapevine (Vitis vinifera). We investigated the involvement of various partners (calcium, ROS, reversible phosphorylation) in MeJA-induced responses by using a pharmacological approach. We used specific calcium channel effectors and inhibi ...

Abstract:
... Barley displays a great genetic diversity, constituting a valuable source to delineate the responses of contrasted genotypes to environmental constraints. Here, we investigated the level of oxidative stress and the participation of antioxidant systems in two barley genotypes: Express, a variety known to be sensitive to drought, and Saïda, an Algerian landrace selected for its tolerance to water de ...

Abstract:
... Nitrogen availability is an important limiting factor for plant growth. Although NH4+ assimilation is energetically more favorable than NO3−, it is usually toxic for plants. In order to study if an improved ammonium assimilatory metabolism could increase the plant tolerance to ammonium nutrition, tomato (Solanum lycopersicum L. cv P-73) plants were transformed with an NH4+-dependent asparagine syn ...

Abstract:
... Despite the importance of seed oil bodies (OBs) as enclosed compartments for oil storage, little is known about lipid and protein accumulation in OBs during seed formation. OBs from rapeseed (Brassica napus) consist of a triacylglycerol (TAG) core surrounded by a phospholipid monolayer embedded with integral proteins which confer high stability to OBs in the mature dry seed. In the present study, ...

Abstract:
... Rice (Oryza sativa) is the most important crop for human consumption, providing staple food for more than half of the world’s population. Rice is conventionally grown under flooded conditions for most of its growing cycle. However, about half of the rice area in the world does not have sufficient water to maintain optimal growing conditions and yield is reduced by drought. One possible way to incr ...

Abstract:
... Beside a direct toxicity, cadmium impact on plants involves both a secondary-induced water stress and an oxidative stress. Proliferating cell lines of Atriplex halimus were selected for their sensitivity or resistance to polyethylene glycol (PEG 10,000, 20%) and then exposed to 100 μM CdCl2 in the simultaneous presence or absence of PEG 20% or 150 mM NaCl. The PEG resistant cell line exhibited a h ...

The response of rice plants to inoculation with an arbuscular mycorrhizal (AM) fungus, Azospirillum brasilense, or combination of both microorganisms, was assayed under well-watered or drought stress conditions. Water deficit treatment was imposed by reducing the amount of water added, but AM plants, with a significantly higher biomass, received the same amount of water as non-AM plants, with a po ...

Abstract:
... Oxylipins have been extensively studied in plant defense mechanisms or as signal molecules. Depending on the stress origin (e.g. wounding, insect, pathogen), and also on the plant species or organ, a specific oxylipin signature can be generated. Salt stress is frequently associated with secondary stress such as oxidative damage. Little is known about the damage caused to lipids under salt stress c ...

Abstract:
... Phenylalanine ammonia-lyase (PAL, EC 4.3.1.5) catalyzes the first step in the phenylpropanoid pathway, and is considered an important regulation point between primary and secondary metabolism. In the present work we analyzed expression of the PAL genes in leaves of Arabidopsis thaliana rosette-stage plants in response to nitrogen depletion at temperatures ranging from 5 to 30 °C. Only PAL1 and PAL ...

Abstract:
... Mucilage is thought to play a role in salinity tolerance in certain halophytic species by regulating water ascent and ion transport. The localization and composition of mucilage in the halophyte Kosteletzkya virginica was therefore investigated. Plants were grown in a hydroponic system in the presence or absence of 100 mM NaCl and regularly harvested for growth parameter assessment and mucilage an ...
