nadph as a quality footprinting in Horticultural Crops marketability
Trends in Food Science and Technology, 2020Co-Authors: Morteza Soleimani Aghdam, Jose M Palma, Francisco J CorpasAbstract:Abstract Background During their post-harvest life, Horticultural Crops are affected by a diverse range of processes, such as natural in planta senescence and fungal infection, as well as artificial conservation techniques, leading to a deterioration in nutritional quality due to chilling damage. Given its intracellular reducing power, the supply of NADPH needs to be optimized in order to maintain multiple metabolic pathways involved in the natural ripening and post-harvest life of Horticultural Crops. Scope and approach As a whole series of reactions are involved in the generation and functioning of the cellular NADPH pool, the homeostasis of NADPH integrates and coordinates different metabolic pathways involved in physiological processes. In this review, we describe the major pathways in NADPH metabolism which modulate the principal enzymes present in subcellular compartments that generate and consume NADPH. Special attention will be paid to its role in fruits and vegetables and its possible use as an indicator of Horticultural crop quality. In addition to playing a key role in cellular redox status, NADPH could also be used as a footprint of Horticultural crop quality for marketing purposes given its involvement in processes such as photosynthesis, carbohydrate activity, reactive oxygen species (ROS) and fatty acid metabolisms, the pentose phosphate pathway, jasmonic acid biosynthesis, as well as shikimate and phenylpropanoid pathways operating in secondary metabolite biosynthesis. Key findings and conclusions Intracellular NADPH metabolism could provide a physiological, biochemical and molecular footprint for the sensory and nutritional quality of post-harvest Horticultural Crops and their marketing worldwide.

ensuring sufficient intracellular atp supplying and friendly extracellular atp signaling attenuates stresses delays senescence and maintains quality in Horticultural Crops during postharvest life
Trends in Food Science and Technology, 2018Co-Authors: Morteza Soleimani Aghdam, Abbasali Jannatizadeh, Gopinadhan PaliyathAbstract:Abstract Background As universal energy currency, intracellular ATP (iATP) shortages in Horticultural Crops during postharvest stresses and senescence. In addition to function as intracellular energy currency, ATP serves as friendly extracellular signaling molecule (eATP). Scope and approach Postharvest treatments attenuate stresses, delay senescence and maintain quality in Horticultural Crops by ensuring sufficient iATP supplying, which was accompanied with lower phospholipase D (PLD) and lipoxygenase (LOX) enzymes activity concomitant with higher antioxidant system activity which along with higher heat shock proteins (HSPs) accumulation resulting in lower reactive oxygen species (ROS) accumulation leading to higher membrane unsaturated/saturated fatty acids (unSFA/SFA), higher shikimate and phenylpropanoid pathways activity revealing by higher phenylalanine ammonia lyase (PAL) enzyme activity leading to higher phenols accumulation, higher endogenous proline and glycine betaine accumulation, higher endogenous polyamines accumulation, and higher pathogenesis (PRs) proteins accumulation, which are crucial for membrane fluidity and integrity maintaining and cell wall fortification. In addition to intracellular energy currency, friendly eATP signaling is crucial for promoting iATP biosynthesis machinery activity and reinforcing defense response by triggering jasmonic and salicylic acids signaling pathways. Also, friendly eATP signaling not only is crucial for regulating stomatal closure which is pivotal for attenuating stresses and delaying senescence in Horticultural Crops but also is crucial for postharvest biofactories representing high phenols accumulating fresh Horticultural Crops in response to abiotic stresses which are beneficial for human health. Key findings and conclusions Ensuring sufficient iATP supplying and friendly eATP signaling would be crucial for attenuating stresses, delaying senescence and maintaining quality in Horticultural Crops during postharvest life.

impact of salicylic acid on post harvest physiology of Horticultural Crops
Trends in Food Science and Technology, 2010Co-Authors: M R Asghari, Morteza Soleimani AghdamAbstract:Salicylic acid (SA), an endogenous plant growth regulator, has been found to generate a wide range of metabolic and physiological responses in plants thereby affecting their growth and development. SA as a natural and safe phenolic compound exhibits a high potential in controlling post-harvest losses of Horticultural Crops. In the present review, we have focused on various intrinsic biosynthetic pathways and effects of exogenous salicylic acid on post-harvest decay and disease resistance, oxidative stress, fruit ripening, ethylene biosynthesis and action, fruit firmness, respiration, antioxidant systems and nutritional quality have also been discussed.

photovoltaic water pumping systems for Horticultural Crops irrigation advancements and opportunities towards a green energy strategy for mozambique
Sustainable Energy Technologies and Assessments, 2019Co-Authors: Rosa J Chilundo, Diana Neves, Urânio S MahanjaneAbstract:Abstract In developing countries, as in Mozambique's case, with about 28.8 million inhabitants, 70% does not have access to the conventional electricity network and 80% depends on agriculture for their subsistence, however, only 5% of the cultivated area is irrigated, and only 1% of the energy from the grid is destined for agriculture. The low index of the population with access to electricity leads to the development of affordable and clean energy for agricultural and domestic uses in accordance with the second and seventh objective of the sustainable development goals. Photovoltaic water pumping systems (PVWPS) have been widely used to increase access to energy for irrigation in many countries and several tools' design are being developed to improve their performance and deployment. However, during the PVWPS design, many of existing tools somehow fail by considering the water demand as a constant throughout Crops productive cycle. In this paper, a qualitative analysis of Horticultural Crops water demand on PVWPS design for irrigation is made. The advancements and opportunities of Mozambique in the adoption of PVWPS for irrigation are also made, exploring the best perspective of transition for Mozambique green energy strategy needs. From the qualitative analysis, the results show that the water demand of Horticultural Crops is dynamic throughout the productive cycle, which allows a surplus of electrical energy after the irrigation that can be saved and possibly redirected to cover other electrical energy needs. Mozambique has favorable conditions in that regards to the available weather conditions and renewable policy framework in general, in addition to other existent favorable conditions. The Mozambican government may adopt PVWPS for Horticultural Crops irrigation as a strategy to increase access to energy for irrigation, and as an alternative energy source in order to minimize the high rates of lack of access to energy.

genomic resources in Horticultural Crops status utility and challenges
Biotechnology Advances, 2011Co-Authors: Humira Sonah, Rupesh Deshmukh, Vinay Singh, Deepak K Gupta, Nagendra K Singh, T R SharmaAbstract:A significant review of status and availability of genomic resources in Horticultural Crops can be utilized for the efficient exploitation of the current research in developing improved varieties and also defining future goals. In this review, we describe the current genomic resources available in major Horticultural Crops and utility of the genomic and genic sequence information for isolating and characterizing novel useful genes and designing new DNA markers. We have found that these genomic resources have been utilized for both basic and applied research; however the progress is relatively slow. Recent advances in automation and high throughput techniques used in decoding plant genomes play an important role to speed up the genomic research. With the establishment of genome and transcriptome sequencing projects for several Horticultural Crops, huge wealth of sequence information have been generated. These sequence information have been used extensively for analyzing and understanding genome structures and complexities, comparative and functional genomics and to mine useful genes and molecular markers. However, certain limitations present a number of challenges for the generation and utilization of genomic resources in many important Crops.
