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

• Programmed cell death remodels lace plant leaf shape during development [3].
• We have postulated that the latter phenomenon would be detectable when SA is synthesized locally in plant leaves [4].
• Abscisic acid (ABA) triggers a complex sequence of signaling events that lead to concerted modulation of ion channels at the plasma membrane of guard cells and solute efflux to drive stomatal closure in plant leaves [5].
• Oligogalacturonide fragments that activate defensive genes in plant leaves heretofore have been thought to be generated only by pathogen-derived pectin-degrading enzymes, because polygalacturonase (PG) activity has not been reported in leaves [6].
• Hydrogen peroxide is generated systemically in plant leaves by wounding and systemin via the octadecanoid pathway [7].

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

• We devised a method for the simultaneous extraction of these compounds from plant leaves to quantitate changes in the levels of jasmonate family members during health and on wounding [15].
• Interplant communication: airborne methyl jasmonate induces synthesis of proteinase inhibitors in plant leaves [16].
• Recent evidence indicates that the presence of serine proteinase inhibitors in plant leaves can reduce predation by insects [17].
• Singlet oxygen generation from the reaction of ozone with plant leaves [18].
• Peroxisomal localization and properties of tryptophan aminotransferase in plant leaves [19].

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].

Analytical, diagnostic and therapeutic context of Plant Leaves

• The case of a 5-year-old girl who survived a near-fatal ingestion of yew plant leaves after treatment with CPR, transcutaneous pacing, and digoxin-specific FAB antibody fragments is presented [25].
• Estimation of total DNA in crude extracts of plant leaf tissue using 4',6-diamidino-2-phenylindole (DAPI) fluorometry [26].
• The dot and Western blot analyses indicated that RBSDV could be detected with a high sensitivity in crude extracts of diseased plant leaves using a purified GST fusion protein [27].
