Botrytis cinerea induces local hypoxia in Arabidopsis leaves.

רק משתמשים רשומים יכולים לתרגם מאמרים

התחבר הרשם

Low oxygen availability is often associated with soil waterlogging or submergence, but may occur also as hypoxic niches in otherwise aerobic tissues. Experimental evidences assign a role in Botrytis cinerea resistance to a group of oxygen-unstable Ethylene Response Factors (ERF-VII). Given that

[Thermal dissipation pathway in cucumber seedling leaves under hypoxia stress].

התחבר הרשם

A water culture experiment was conducted to study the relationship between photosynthetic thermal dissipation and xanthophyll cycle in cucumber seedling leaves under hypoxia stress (the dissolved oxygen concentration in nutrient solution was 0.9-1.1 mg x L(-1)). Under the hypoxia stress, there was a

Metabolic adaptation to prolonged anoxia in leaves of American cranberry (Vaccinium macrocarpon).

התחבר הרשם

The indigenous North American Cranberry (Vaccinium macrocarpon), when cultivated in specially constructed cranberry bogs, is normally flooded in winter to prevent frost injury. This protection under ice can give rise to prolonged periods of anoxia, which depending on the state of the vines and

Acetaldehyde and ethanol biosynthesis in leaves of plants.

התחבר הרשם

Leaves of terrestrial plants are aerobic organs, and are not usually considered to possess the enzymes necessary for biosynthesis of ethanol, a product of anaerobic fermentation. We examined the ability of leaves of a number of plant species to produce acetaldehyde and ethanol anaerobically, by

Differential response of gray poplar leaves and roots underpins stress adaptation during hypoxia.

התחבר הרשם

The molecular and physiological responses of gray poplar (Populus x canescens) following root hypoxia were studied in roots and leaves using transcript and metabolite profiling. The results indicate that there were changes in metabolite levels in both organs, but changes in transcript abundance were

Phloem unloading in tobacco sink leaves: insensitivity to anoxia indicates a symplastic pathway.

רק משתמשים רשומים יכולים לתרגם מאמרים

התחבר הרשם

Phloem unloading in transition sink leaves of tobacco (Nicotiana tabacum L.) was analyzed by quantitative autoradiography. Detectable levels of labeled photoassimilates entered sink leaves approx. 1 h after source leaves were provided with (14)CO2. Samples of tissue were removed from sink leaves

Carbon isotope analysis of acetaldehyde emitted from leaves following mechanical stress and anoxia.

רק משתמשים רשומים יכולים לתרגם מאמרים

התחבר הרשם

Although the emission of acetaldehyde from plants into the atmosphere following biotic and abiotic stresses may significantly impact air quality and climate, its metabolic origin(s) remains uncertain. We investigated the pathway(s) responsible for the production of acetaldehyde in plants by studying

Life-history strategies affect aphid preference for yellowing leaves.

רק משתמשים רשומים יכולים לתרגם מאמרים

התחבר הרשם

According to the nutrient-translocation hypothesis, yellowing tree leaves are colonized by aphids at the end of the growing season owing to improved availability of nutrients in the phloem sap after chlorophyll degradation. We measured aphid densities on potted Betula pendula seedlings in a field

Stress Induction of Mitochondrial Formate Dehydrogenase in Potato Leaves

רק משתמשים רשומים יכולים לתרגם מאמרים

התחבר הרשם

In higher plants formate dehydrogenase (FDH, EC 1.2.1.2.) is a mitochondrial, NAD-dependent enzyme. We previously reported that in potato (Solanum tuberosum L.) FDH expression is high in tubers but low in green leaves. Here we show that in isolated tuber mitochondria FDH is involved in

Translocation of assimilates and phosphate in detached bean leaves.

התחבר הרשם

(14)C-assimilates were accumulated by the veins in the blades and transported basipetally into the petioles of detached leaves of Red Kidney bean (Phaseolus vulgaris L.). Neither process was greatly affected by mild moisture stress, age of fully enlarged leaves, or period in the dark prior to

Efflux of sucrose from minor veins of tobacco leaves.

רק משתמשים רשומים יכולים לתרגם מאמרים

התחבר הרשם

Mature leaves import limited amounts of nutrient when darkened for prolonged periods. We tested the hypothesis that import is restricted by the apoplast-phloem loading mechanism, ie., as sucrose exits the phloem of minor veins it is retrieved by the same tissue, thus depriving the mesophyll of

Long-term anoxia tolerance in leaves of Acorus calamus L. and Iris pseudacorus L.

רק משתמשים רשומים יכולים לתרגם מאמרים

התחבר הרשם

Mature green leaves of Acorus calamus and Iris pseudacorus have been shown to survive at least 28 d of total anoxia in the dark during the growing season, increasing up to 75 d and 60 d in overwintering leaves in A. calamus and I. pseudacorus, respectively. During the period of anaerobic incubation

Cuticle ultrastructure, cuticular lipid composition, and gene expression in hypoxia-stressed Arabidopsis stems and leaves.

UNASSIGNED An increased permeability of the cuticle is closely associated with downregulation of genes involved in cuticular lipid synthesis in hypoxia-stressed Arabidopsis and may allow plants to cope with oxygen deficiency. The hydrophobic cuticle layer consisting of cutin polyester and cuticular

Global gene expression responses to waterlogging in leaves of rape seedlings.

Soil waterlogging is a serious constraint to crop production. We investigated the physiological responses of rape (Brassica napus L.) seedlings to waterlogging stress and analyzed global gene transcription responses in the aerial leaves of waterlogged rape seedlings. Seedlings of 'Tammi' and

Isolation of six isoprenylated biflavonoids from the leaves of Garcinia subelliptica.

The acetone-soluble parts of Garcinia subelliptica leaves were analyzed and six new biflavonoids were isolated, i.e., garciniaflavones A-F (1-6), as well as the five known biflavonoids amentoflavone (7), podocarpusflavone A (8), (+)-morelloflavone (9), (+)-morelloflavone-7"-O-β-glucopyranoside (10),
