Solanum dulcamara plants, however, lost most submerged leaves in our experiment, thus constraining their capacity for underwater photosynthesis. One may expect then that after the shoot restores contact with the atmosphere, the renewed oxygen supply to the adventitious root primordia would result in immediate by: Background. Cultivated potato (Solanum tuberosum L.) is one of the most important food crops in the the United States, over half of the potato tubers produced are processed to make chips, french fries, and similar products .A crucial quality requirement for these tubers is the ability to produce light-colored, flavorful fried products that will be acceptable to consumers.

Dark respiration and carbohydrate metabolism in leaves of Solanum dulcamara L. Author: Hattersley, B. ISNI: Awarding Body: University of East Anglia Current Institution: University of East Anglia Date of Award: Availability of Full Text. Summary. The relationships between photosynthesis, carbohydrate metabolism and respiration in leaves of C 3 plants are reviewed.
We first provide an overview of how mitochondrial respiration relies on, and responds to, the supply of photosynthetic products in the by: Abstract.
Photosynthesis was studied in relation to the carbohydrate status in intact leaves of the C 4 plant Amaranthus rate of leaf net CO 2 assimilation, stomatal conductance and intercellular partial pressure of CO 2 remained constant or showed little decline towards the end of an 8-h period of illumination in ambient air ( μbar CO 2, 21% O 2).Cited by: To measure dark respiration, the chamber was covered with a layer of black paper and then a layer of white paper to exclude light within the cuvette.

This study describes the response to partial submergence of bittersweet (Solanum dulcamara). Bittersweet is a Eurasian species that grows both in dry habitats such as coastal dunes, and in wetlands, and therefore is a suitable model plant for studying responses to Cited by: Black bars represent the percentage of all Solanum dulcamara genes that were significantly up- and downregulated in response to 24 hr of Spodoptera exigua feeding in each of 81 GO terms, which.
Effects of nitrogen (N) supply on leaf maximum net assimilation rate (A max, μmol CO 2 m −2 s −1), dark respiration (R d, μmol CO 2 m −2 s −1) and quantum efficiency (α c, μmol CO 2 (μmol PAR) −1) of olive leaves measured 58 days after the start of the by: Correlation of all anatomical variables was highly significant with dark respiration and NPS per dry weight but insignificant for NPS per leaf area.
In the variable temperature treatments, photosynthetic acclimation occurred with a shift in optimum temperature for NPS in the direction of prevailing growth by: In nature, plants are frequently subjected to multiple biotic and abiotic stresses, resulting in a convergence of adaptive responses.
We hypothesised that hormonal signalling regulating defences to different herbivores may interact with drought responses, causing distinct resistance phenotypes. To test this, we studied the hormonal and transcriptomic responses of Solanum dulcamara subjected to Cited by: 1. In senescing leaves by the end of the plant vegetation, potential photosynthesis and true photosynthesis were reduced, whereas dark respiration remained essentially unchanged.
Introduction. Light is the most important source of energy for plant photosynthesis and is also an important signal for plant growth and development (Hudák et al., ; Jiao et al., ).It is known that plants can respond to the quantity of light and photoperiod length, and to its quality (Neff et al.,Yamazaki, ).Light qualities are known to control morphogenesis, growth and Cited by: This hypothesis is strengthened by the observation on 'gestaltless' nectaries in Brassica juncea (Mathur et al., ) and of an EFN-like wound secretion on the leaves of Solanum dulcamara.
Leaves were harvested at the end of the day or end of the night from separate Craterostigma plants and then dipped in a solution of 2 mM EDTA and 5 mM sodium phosphate for 15 h in the dark. After this period the percentage of the carbohydrate present in different carbohydrates was determined by: Hájek T, Adamec L () Photosynthesis and dark respiration of leaves of terrestrial carnivorous plants.

cv SNN during an incompatible interaction with Phytophthora nicotianae van Breda de Haan were investigated and compared with defence reactions. Hypersensitive cell death was preceded by a rapid and highly localized shift to non‐assimilatoric metabolism.
In commercial potatoes (Solanum tuberosum) there are two major glycoalkaloids, α-chaconine and α-solanine, both triglycosides of the common aglycone two compounds comprise about 95% of the glycoalkaloids present in potato tubers.
Their hydrolysis products, the β and γ forms and solanidine, may also be present, but in relatively insignificant by: 9. To this end, we determined the nocturnal carbohydrate-export rates from leaves with an optimal nitrogen supply, and the correlation between the nitrogen concentration and the dark respiration of leaves.
The specific energy costs of carbohydrate export from starch-storing source leaves were determined both experimentally and by:. Mature leaves of Lolium temulentum L. remained photosynthetically competent for some days following excision. During this time, amounts of soluble carbohydrate rose markedly and there was substantial accumulation of sucrosyl‐fructans.
Cell‐free extracts of excised leaves showed enhanced ability to synthesize oligofructosides from sucrose in Cited by: G. rostochiensis and G. pallida have the same host range. They are able to develop on all tuberous species of the cultivated plants, they freely develop on Lycopersicon esculentum (tomato) and are able to reproduce on Solanum melongena (egg-plant).
