Here, we tested whether rapid changes in carbohydrate transport and partitioning to storage organs would be induced by jasmonic acid (JA), a plant-produced signal of herbivore attack known to induce resistance. Carbon-11, introduced as (11)CO(2), was used to track real-time carbohydrate transport and partitioning nondestructively in Populus species before and 12 h after application of JA to a s...

one of the major problems in reproduction of potato minitubers, is the low germination due to dormancy period that it’s led to low germination percentage, vigor and rot of tubers planted. therefore a factorial experiment based on the completely randomized design with three replications was carried out with a topic of the effects of application of rindite in various concentrations (0, 0.2, 0.4 a...

Abstract Through the annual cycle of plant growth and dormancy, winter season leads to profound metabolic changes allowing plants undergo cold acclimation. In boreal environments, conditions are changing rapidly likely cause damage commercial wild lowbush blueberry. this study, we addressed level frost hardiness determined role environmental factors nonstructural carbohydrates (NSCs) on hardine...

Apple (Malus x domestica Borkh.) grown in a Mediterranean climate depends on regular irrigation throughout the growing season. The objective of the current study was to elucidate the changes in carbohydrate storage and utilization by mature, field-grown apple trees in response to water availability to the trees and to the level of cropping. Fourteen-year-old apple trees cv. 'Golden Delicious' w...

Food practices have always been a key issue to reconstruct part of the cultural identities past and present societies. In archaeology, question vegetal processing consumption has generally discussed through different, yet complementary lenses that include botanical remains cooking pots. However, it seldom integrated in combined approach. Our paper explores characteristics role plant transformat...

Data from plants transformed to accumulate fructan are assessed in the context of natural concentrations of reserve carbohydrates and natural fluxes of carbon in primary metabolism: Transgenic fructan accumulation is universally reported as an instantaneous endpoint concentration. In exceptional cases, concentrations of 60-160 mg g(-1) fresh mass were reported and compare favourably with natura...

Flour and starch isolated from the tubers of Scirpus grossus were investigated for their physicochemical properties and starch digestibility. The flour was extracted using two different processes namely peeled and unpeeled processes. Proximate analysis revealed that the flours from both processes contain considerably high total starch, more than 80%, which indicate their potential use as starch...

Gall forming phylloxera may compete for nutrients with meristematic tissues and develop heterotrophic structures that act as carbon sinks. In this work, we studied the underlying starch metabolism, sink-source translocation of soluble sugars towards and within root galls. We demonstrated that nodosities store carbohydrates by starch accumulation and monitored the expression of genes involved in...

Changes in seed dormancy were selected during the domestication of crop plants from wild-plant species, because some features of dormancy that provide ecological advantages presented agronomic disadvantages within a farmed system. Seed dormancy varies widely among seed batches, even for seeds of the same genotype, indicating large environmental influences. For genetic studies, it is essential t...
