... Humulus lupulus L. (hop) is a dioecious climbing plant of which the females bear particular inflorescences, called hops, ‘cones’ or ‘strobiles’, made of a series of membranaceous bracts and bracteoles. At the base of these ‘cones’ occur glandular trichomes where a complex metabolome is synthesized mainly consisting of terpenoids (constituents of essential oil) and original prenylated phenolic comp ...
... Fall dormancy is a vital component of alfalfa (Medicago sativa L.) yield in northern climates, but selection for the trait is often done at the expense of winter survival. We performed one cycle of selection to reduce fall dormancy in two winter hardy cultivars (Yellowhead and Peace) using a new indoor screening method. We compared the reduced dormancy populations with their respective initial cul ...
... Systemic acquired resistance is an essential immune response that triggers a broad‐spectrum disease resistance throughout the plant. In the present study, we identified a peanut lesion mimic mutant m14 derived from an ethyl methane sulfonate‐mutagenized mutant pool of peanut cultivar “Yuanza9102.” Brown lesions were observed in the leaves of an m14 mutant from seedling stage to maturity. Using Mut ...

Abstract:
... Air pollutants influence the morphological, physiological, and biochemical status of plants, and their impacts vary substantially among different species and cultivars. Current review synthesises published literature on the assessment of air pollution impacts on vegetation, with a specific focus on chronicling and summarizing scientific methods that quantify those impacts. Investigations carried o ...
... The profitability of modern apple orchard plantings depends largely on how rapidly the costs of planting are returned. Tree establishment and growth in the formative years are often can be limited by transplant shock associated with bare-root trees. In this experiment, we examined the effect of two planting systems, air-pruning containers, and field-grown liners, on above- and below-ground growth ...
... KEY MESSAGE: An approach to release ‘frozen’ variability in apomictic species using sexuality of another species, eventually its utilization in crop improvement and de-novo domestication of crop wild relatives is presented. Pennisetum squamulatum, a secondary gene pool species of pearl millet (P. glaucum), harbours many desirable traits. However, it was neither utilized to improve pearl millet fod ...
... KEY MESSAGE: Association analysis resulted in the identification of specific StGWD alleles causing either an increase or decrease in starch phosphate content which was verified in diploid and tetraploid potato mapping populations. Potatoes are grown for various purposes like French fries, table potatoes, crisps and for their starch. One of the most important aspects of potato starch is that it con ...
... Palmer amaranth (PA) is one of the major weeds in sweetpotato reducing its quantity and quality. The widespread and repeated use of chemical herbicides has led PA to develop resistance for such chemicals. In addition, chemical herbicides are incompatible with the organic production system. It is imperative to find sustainable weed management strategies to provide weed control suitable for organic ...
... What occurs when virus infection is spreading within a mixed plant species population? This question is important not only for economically significant, mixed species managed systems but also for environmentally significant mixed wild species populations. It received attention in recently published ecological studies on wild plant species, but these, and recent general pasture research publication ...
... Weeds are often considered undesirable as they interfere with the habitat of native plants, and therefore they are underestimated and underutilised. In fact, some edible weeds have beneficial nutritional and medicinal values. Alternanthera sessilis (L.) R. Br. ex DC., an edible medicinal weed is a species of the Amaranthaceae family that consists of two cultivars: green and red. Local communities ...
... Lettuce (Lactuca sativa) is one of the most important vegetable crops in the world. As a leafy vegetable, the polymorphism of lettuce leaves from dark to pale green is an important trait. However, the genetic and molecular mechanisms underlying such variations remain poorly understood. In this study, one major locus controlling the polymorphism of dark‐ and pale‐green leaves in lettuce was identif ...

Abstract:
... The aim of the present study was to assess the variations in chemical composition and biological activities of essential oil of Curcuma longa rhizome local cultivars collected from four varied altitudes and habitats of Kumaun and Garhwal regions of Uttarakhand, India. The essential oil was collected from the rhizomes by hydrodistillation extraction using the Clevenger apparatus. Yields of essentia ...
... Rapid industrialization and over-use of agrochemicals may lead to cadmium (Cd) contamination in agricultural soil, posing serious threat to human health. In recent times, application of plant nutrients and other growth promoting substances, like, nanoparticles (nZVI), silicon, salicylic acid were reported to have ameliorated Cd toxicity, in this regard, nitrogen (N) amendment can be a promising te ...
... Salt stress represents one of the most problematic abiotic stress affecting plants worldwide. In saline soils, plants try to counteract the consequences of salt stress by physiological changes, leading to the decreasing of both osmotic and oxidative stresses. Plant growth-promoting bacteria (PGPB) can ameliorate plant stress response by several mechanisms. In this work, we focused on the effects o ...
... Citrus tristeza virus (CTV) is the most severe viral disease for citrus production. Many strains of CTV have been characterized and their symptomology widely varies, ranging from mild or asymptomatic infections, to severe symptomology that results in substantial yield loss or host death. The capacity of the different CTV strains to affect the biochemistry of different citrus species has remained l ...
Datasets:
Data from: Amino acid, sugar, phenolic, and terpenoid profiles are capable of distinguishing Citrus tristeza virus infection status in grapefruit, lemon, mandarin, and sweet orange leaves
... Growing potatoes in temperate regions often leads to nitrogen (N) leaching, however this could be significantly reduced with drip irrigation and nitrogen fertigation if the timing and amounts of the applications matched the crop demand. Determination of when and how much to apply is not straightforward, particularly because the N mineralisation during the potato-growing season is unknown. The pres ...
... We measured the concentration of 13 terpenes in musts of 3 different apple cultivars fermented spontaneously, with Ethanol RED yeast (Saccharomyces cerevisiae) or Cider Yeast (Saccharomyces bayanus). Then we analysed obtained data with PCA with various packages in R to assess how different types of fermentation and apple cultivars affected terpene profile. The most informative results of PCA were ...

Abstract:
... The plants are constantly subjected to varying degree of environmental stress. These stresses results in severe damage to the DNA of the plants, which if not repaired can lead to the impairment of their genetic material, and can prove fatal for the plants. The present work studies the damage to the genomic DNA in response to salinity and drought stress on the indica rice cultivars. The comet assay ...
... Fusarium head blight (FHB), elicited mainly by the fungal pathogen Fusarium graminearum (Fg), causes serious damages to global wheat production. Development of resistant cultivars is the most efficient measure for controlling FHB, which requires efficient identification and utilization of the wheat germplasm carrying FHB resistance genes. Because the Fhb1 gene recently cloned from the wheat cultiv ...
... The light-harvesting chlorophyll a/b-binding proteins (Lhcb) constitute the antenna system of the photosynthetic apparatus that has an essential function in photosynthesis and modulating stress responsiveness. In this study, we identified 35 Lhcb genes (BnLhcbs) in the rapeseed (Brassica napus L.) genome, which were clustered into 8 groups. The BnLhcb genes were distributed on 15 chromosomes of ra ...
... Premature leaf senescence has a profound influence on crop yield and quality. Here, a stable premature senescence mutant (GSm) was obtained from the common wheat (Triticum aestivum L.) cultivar Chang 6878 by mutagenesis with ethyl methanesulfonate. The differences between the GSm mutant and its wild-type (WT) were analyzed in terms of yield characteristics, photosynthetic fluorescence indices, and ...
