The new hybrids of Dioscorea alata exhibited contrasted susceptibility to browning in relation to their total phenolic content (r = 0.91). The detailed polyphenol profiles of “INRA15”, highly susceptible to browning, and of “ ...

Abstract:
... This work presents a characterisation of the fruit and the bruising caused by some common detachment methods (manual, stick, shaker comb, branch shaker) and interception methods (net or padding) in common table olive varieties. We took pictures of fruit samples inside a special device, and the images were processed to extract characteristic parameters of shape and size (number of spots, Feret diam ...
... To develop an effective genome editing tool for blueberry breeding, CRISPR-Cas9 and CRISPR-Cas12a were evaluated for their editing efficiencies of a marker gene, beta-glucuronidase (gusA), which was previously introduced into two blueberry cultivars each a single-copy transgene. Four expression vectors were built, with CRISPR-Cas9 and CRISPR-Cas12a each driven by a 35S promoter or AtUbi promoter. ...
... Cadmium is a toxic non-essential metal for almost all living systems. It is one of the biggest challenges for farmlands and the food chain because of its toxic effect on human health. This research aims to determine the Cd content in soils, litter and cacao beans, following the Cd fluxes within each cacao system using the two-dimensional electrical resistivity tomography technique. The study was c ...
... Camelina [Camelina sativa (L.) Crantz] is an oilseed crop belonging to the Brassicaceae family that has attracted worldwide attention because of its agronomic and qualitative characteristics. This crop can adapt well to different environments and produce oil suitable for multiple bio-based uses. The most commonly measured and reported components of camelina seeds are fatty acids, proteins, and vit ...

Abstract:
... Camelina [Camelina sativa (L.) Crantz] has increased cold, heat, and drought tolerance and decreased susceptibility to diseases and pests than oilseed rape (Brassica napus L.). Because water deficit at sowing leads to unsatisfactory stand establishment due to irregular seed germination and emergence, the aim of this study was to understand the response of camelina germination under osmotic stress ...
... An efficient in vitro morphogenesis, specifically through somatic embryogenesis, is considered to be a crucial step for the application of modern biotechnological tools for genetic improvement in olive (Olea europaea L.). The effects of different ethylene inhibitors, i.e., cobalt chloride (CoCl₂), salicylic acid (SA), and silver nitrate (AgNO₃), were reported in the cyclic somatic embryogenesis of ...

Abstract:
... This study aimed to investigate the effect of irrigation with saline water on fruit quality, yield, and plant nutrition of tomato (Lycopersicon esculentum Mill.) cultivars. Tomato cultivation was carried out under protected environment conditions in a double row system with drip irrigation performed according to the demand of the plants. Commercial fruit weight, commercial fruit number, fruit yiel ...

Abstract:
... Russian wheat aphid (RWA) is one of the most challenging pests for wheat crops globally. In South Africa, RWA has breached the strategy of introducing resistant genes into wheat plants, and so far, five RWA biotypes with different virulence levels have been documented in the field. Our study investigated how the cell wall plays a defensive role in Tugela-Dn1 (susceptible) and-Dn5 (resistant) culti ...
... The Fusarium crown and root rot pathogen Fusarium culmorum (Fc) is a hemibiotrophic pathogen, with a short biotrophic phase preceding necrotrophic life-style. In this study, for the first time, a comparative proteomic analysis was made in seedling roots of two wheat cultivars Falat (susceptible) and Sumai3 (resistant) subjected to Methyl jasmonate (MeJA) at 2 days post Fc-inoculation (2 dpi) to un ...
... In the subtropical grain region of eastern Australia, two experiments were conducted, one initially with 2490 P. thornei/kg soil, the other with 8150 P. thornei/kg soil at 0–0.9 m soil depth. We determined the effect of P. thornei, residual from a weed-free fallow and pre-cropping with several cultivars each of barley (Hordeum vulgare), faba bean (Vicia faba), chickpea (Cicer arietinum), and wheat ...
... Heterosis or hybrid vigor is extensively used in plant breeding. However, the contribution of metabolites to heterosis is still elusive. Here, we systematically identified the non-volatile and volatile metabolites of two hybrids and their parents in Camellia sinensis. The metabolomics analysis showed prevalent non-additive accumulation in hybrids, among which the non-additive nucleotides, alkaloid ...
... Fruit ripening involves changes in physical, physiological, biochemical, and metabolic activities through the actions of enzymes and regulatory genes. In this study, we elucidate primary and secondary metabolites and antioxidant activities of green ‘Hayward’ and gold ‘Haegeum’ kiwifruit cultivars during ripening by comparing ethylene-treated fruit to the control. A total of 36 primary metabolites ...
... Oats and their seeds, stems, and leaves are approved for use as safe food ingredients. Oat seedlings are environmentally friendly and are becoming increasingly popular as they provide several health benefits. We used the UPLC-CAD to quantitatively analyze isolated compounds (1–11) between 15 cultivars of oat seedlings and their harvest time. Maximum average amount of total contents of isolated com ...
... Background. One of the important indicators of the nutritional value of amaranth is the high content of protein and lipids in seeds. Hence, obtaining and identifying such forms of amaranth through breeding, so that they also possessed resistance to abiotic stressors, is an important task.Materials and methods. Leaves and seeds of Amaranthus cruentus L. and mutants of the second inbred generation o ...

Abstract:
... A large number of apple varieties (35) from the same germplasm were investigated over two consecutive harvest years. A total of 39 volatile compounds were identified by HS-SPME-GC-MS, and quantified by external standards. Principal component analysis was applied to study the relationship between varieties and volatiles. To obtain better discrimination, 23 of 35 apple varieties were classified into ...
... Verticillium wilt, caused by Verticillium dahliae is considered the most serious biotic threat to olive trees. The disease is detected in almost all regions where olive is cultivated, and it may cause olive decline and dieback. The aim of this study was to determine the incidence and distribution of Verticillium wilt on olive trees in Istria (Croatia), to identify pathotype groups and race structu ...
... Although strawberry can be cultivated in all types of climate, it grows best in temperate climates, limiting its cultivation in certain countries or regions with tropical or subtropical climates. The objective of this study was to verify the genetic diversity of 34 pre-selected day-neutral strawberry genotypes in humid tropical and subtropical conditions through characterization of morpho-agronomi ...
... Grape seeds are a rich source of flavan-3-ol monomers, oligomers, and polymers. The diverse profile of compounds includes mainly B-type procyanidins (especially C4→C8 linked molecules) and the key monomers, catechin, and epicatechin that are positively implicated in the ‘French Paradox’. Today grape seed nutraceuticals have become a multi-million-dollar industry. This has created incentives to elu ...
... Powdery mildew is a destructive foliar disease of cucumber (Cucumis sativus L.) under greenhouse conditions. The most used methods for disease control are repeated application of fungicides and use of resistant cultivars. Development of powdery mildew isolates resistant to fungicides have reduced their efficacy. This research compared the efficacy of conventional chemical and biological fungicides ...
