Abstract:
... Intensification of the shrimp sector, also referred to as vertical expansion, has been predominately driven by consecutive incidences of global disease outbreaks, which have caused enormous economic loss for the main producer countries. A growing segment of the shrimp farming industry has opted to use production systems with higher density, biosecurity, and operating control to mitigate the risks ...
... Plants typically respond to waterlogging by producing new adventitious roots with aerenchyma and many wetland plants form a root barrier to radial O₂ loss (ROL), but it was not known if this was also the case for lateral roots. We tested the hypothesis that lateral roots arising from adventitious roots can form a ROL barrier, using root‐sleeving electrodes and O₂ microsensors to assess ROL of Zea ...
... Pre-harvest sprouting (PHS) causes significant losses in wheat yield and quality worldwide. Previously, we cloned a PHS resistance gene, TaPHS1, and identified two causal mutations for reduced seed dormancy (SD) and increased PHS susceptibility. Here we identified a novel allelic variation of C to T transition in 3′-UTR of TaPHS1, which associated with reduced SD and PHS resistance. The T allele o ...
... Enzymatic browning is a major postharvest quality defect of romaine lettuce (Lactuca sativa L.). This study provides the first analysis of the relationship between the browning of leaf ribs and stems across twelve lettuce genotypes (ten cultivars, a breeding line, and a plant introduction). While all samples showed a progressive increase in browning index (BI) and decline in lightness (L*) and hue ...

Abstract:
... BACKGROUND: The full flavor of grape berries is determined by the interaction of sugars, acids, volatile compounds, and other berry properties, such as astringency. Sugars and acids are important for berry taste, whereas volatile compounds are important for the unique berry flavors, e.g., monoterpenes for the Muscat varieties. RESULTS: We explored the basis for ‘fruity’ flavor perception in table ...

Abstract:
... KEY MESSAGE: The novel super-soft kernel phenotype has the potential to improve wheat processing and flour quality. We identified genomic regions associated with this kernel texture in white winter wheat. Grain hardness is a key determinant of wheat milling and baking quality. The recently discovered ‘super-soft’ kernel phenotype has the potential to improve wheat processing and flour quality. How ...
... Pecan (Carya illinoinensis) is a crossing-pollinated nut tree with male and female flowering separated and matured at different time. This dichogamy pattern requires appropriate pollen storage strategy making hybridization successful in the pecan breeding program. In this study, we used pecan cultivar ‘Pawnee’ pollen to optimize germination medium composition on basis of four published formulas. C ...

Abstract:
... Pea (Pisum sativum) is an important grain legume worldwide whose cultivation is severely constrained by the root parasitic weed crenate broomrape (Orobanche crenata), which is widespread in the Mediterranean Basin and Middle East. No resistance is available in commercialized cultivars but some levels of incomplete resistance has been reported in pea landraces and Pisum spp. relatives. In this pape ...

Abstract:
... Environmental factors like temperature and humidity are presumed to greatly influence Fusarium head blight FHB infections in wheat. Anther retention AR, on the other hand, is a morphologically neutral trait that shares a common genetic basis with FHB resistance. In this study, our aims were to: (i) Evaluate two types of corrections of FHB severity scores, namely method-1 via linear regression on f ...
... Early leaf spot (ELS) and late leaf spot (LLS) are major fungal diseases of peanut that can severely reduce yield and quality. Development of acceptable genetic resistance has been difficult due to a strong environmental component and many major and minor QTLs. Resistance genes (R-genes) are an important component of plant immune system and have been identified in peanut. Association of specific R ...

Abstract:
... BACKGROUND AND AIMS: We were interested to know if laboratory screens of root growth could be used to predict root performance and grain yield of wheat when grown in the field. A secondary aim of this work was to explore the relationship between root depth and grain yield. METHODS: We screened 637 wheat lines, composed of elite as well as a limited number of breeding lines, to identify wheat lines ...

Abstract:
... BACKGROUND: The significance of high‐molecular‐weight glutenin subunits (HMW‐GSs) and rye translocations, and their associations with gluten strength for hard wheat used for making bread has been understood well, but remains poorly understood for soft wheat used for making cookies. The influences of HMW‐GSs and rye translocations on the dough‐mixing properties and cookie‐baking quality of soft whe ...

Abstract:
... A diverse set of molecular markers techniques have been developed over the last almost 40 years and used with success for breeding a number of major crops. These have been narrowed down to a few preferred DNA based marker types, and emphasis is now on adapting the technologies to a wide range of crop plants and trees. In this Special Issue, the strength of molecular breeding is revealed through re ...

Abstract:
... The Waxy (Wx) gene that governs amylose synthesis is an old but widely used target in improving the quality of starchy crops. New genome-editing strategies are being deployed to create beneficial Wx alleles with finely tuned amylose content (AC). Precise targeting must be combined with traditional approaches to develop healthier and high-quality breeding lines. ...

Abstract:
... Maize landrace accessions constitute an invaluable gene pool of unexplored alleles that can be harnessed to mitigate the challenges of the narrowing genetic base, declined genetic gains, and reduced resilience to abiotic stress in modern varieties developed from repeated recycling of few superior breeding lines. The objective of this study was to identify extra-early maize landraces that express t ...

Abstract:
... Arabinoxylans (AXs) are one of the major dietary fibre components in wheat. These non-starch polysaccharides have several beneficial health effects and they also have an impact on the technological properties of wheat-based products. It is therefore desirable to breed new varieties with higher amount and different quality arabinoxylans. We have only limited information on the variability of AXs in ...
... The study was aimed to develop rust resistant genotypes with genome of prominent wheat variety HS240 by pyramiding of linked leaf rust and stem rust resistance genes Lr19 and Sr25 with stripe rust resistance gene Yr15. The genotypes FLW13 and FLW20 were used as gene donors for transfer of Yr15 and Lr19/Sr25, respectively. The molecular markers scs265, wmc221, PSY1-E1, and Gb linked to Lr19/Sr25 an ...
