Disease relevance of Plant Leaves

  • We found that the TGBp1 inclusions isolated from the infected plant leaves, but not from E. coli, possess the NTP-binding and NTPase activities [1].
  • All mice treated with the fraction containing febrifugine and isofebrifugine mixture at 1 mg/kg twice a day for 5 consecutive days survived during the experiment, and the change of mean parasitemia level showed almost the same pattern as that from mice treated with the hot-water extract of the same plant leaves [2].

High impact information on Plant Leaves


Biological context of Plant Leaves

  • We found that a tatC mutant strain of DC3000 displayed a number of phenotypes, including loss of motility on soft agar plates, deficiency in siderophore synthesis and iron acquisition, sensitivity to copper, loss of extracellular phospholipase activity, and attenuated virulence in host plant leaves [8].
  • Seasonal variations in cadmium concentrations of plant leaves [9].
  • The methanol extract of M. charantia leaves showed strong oviposition deterrent activity against L. trifolii females on the host plant leaf when it was dipped in the methanol extract at a concentration of 1 g of fresh leaf equivalent/ml [10].
  • The plant leaf suspension (1000 mg/kg; wet weight) as well as its methanol extract (100 mg/kg) showed a remarkable hepatoprotective activity against paracetamol-induced hepatotoxicity as judged from the serum marker enzymes, liver histology and levels of lipid peroxides in liver [11].

Anatomical context of Plant Leaves

  • This study was conducted to test whether the C-terminus of glycolate oxidase, a key enzyme in the glycolate metabolism pathway, is functioning as a targetting signal that directs proteins into plant leaf peroxisomes [12].
  • Hornet venom has 3 major allergens, and another hornet allergen antigen 5 (Dol m V) was previously found to have sequence similarity with a mammalian testis protein and a plant leaf protein [13].
  • The results indicate that in epidermal cells and protoplasts from 50KP plant leaves, the trafficking and tubule-inducing activities of GINV-39KP were specifically blocked while those of ACLSV-50KP and Apple stem grooving virus MP (36KP) were not affected [14].

Associations of Plant Leaves with chemical compounds


Gene context of Plant Leaves

  • Thus AtHKT1 reduces the sodium content in xylem vessels and leaves, thereby playing a central role in protecting plant leaves from salinity stress [20].
  • Expression of tomato BI-1 by agroinfiltration of intact plant leaves provided protection from damage induced by heat-shock and cold-shock stress [21].
  • In addition, the expression of the DC3000 pilA gene appears to contribute to the UV tolerance of P. syringae and may play a role in survival on the plant leaf surface [22].
  • Cytoplasmic fructose-1,6-bisphosphatase may contribute to the regulation of sucrose biosynthesis in plant leaves [23].
  • The tetraspanin BcPls1 is required for appressorium-mediated penetration of Botrytis cinerea into host plant leaves [24].
