How strong is Hedera helix?
This is accomplished through a complex method of attachment starting as adventitious roots growing along the stem make contact with the surface and extend root hairs that range from 20 to 400 μm in length. These tiny hairs grow into any small crevices available, secrete glue-like nanoparticles, and lignify. As they dry out, the hairs shrink and curl, effectively pulling the root closer to the surface. The glue-like substance is a nano composite adhesive that consists of uniform spherical nanoparticles 50-80 nm in diameter in a liquid polymer matrix. Chemical analyses of the nanoparticles detected only trace amounts of metals, once thought to be responsible for their high strength, indicating that they are largely organic. Recent work has shown that the nanoparticles are likely composed in large part of arabinogalactan proteins (AGPs), which exist in other plant adhesives as well. The matrix portion of the composite is made of pectic polysaccharides. Calcium ions present in the matrix induce interactions between carboxyl groups of these components, causing a cross linking that hardens the adhesive.
What is the temperature of Hedera Helix?

What is the genus of Hedera?
The genus name Hedera is the Classical Latin word for 'ivy', which is cognate with Greek χανδάνω ( khandánō) 'to get, grasp', both deriving ultimately from Proto-Indo-European *gʰed- 'to seize, grasp, take'. The specific epithet helix derives from Ancient Greek ἕλιξ ( elix ), ' helix ', and from the Latin helicem, 'spiral', first used around 1600.The binomial in its entirety thus has the meaning "the clinging plant that coils in spirals (helices)". The modern English ivy derives from Middle English ivi, from Old English īfiġ, deriving in turn from Proto-Germanic *ibahs. The meaning is uncertain, but the word may be cognate with the Ancient Greek ἴφυον ( íphuon ), referring to not Hedera helix, but the unrelated English lavender, or Lavandula angustifolia.
How tall does Hedera Helix grow?
Hedera helix is an evergreen climbing plant, growing to 20–30 m (66–98 ft) high where suitable surfaces ( trees, cliffs, walls) are available, and also growing as groundcover where no vertical surfaces occur. It climbs by means of aerial rootlets with matted pads which cling strongly to the substrate.

Where does the term "helix" come from?

Is H. helix weedy?
In the United States, H. helix is considered weedy or invasive in a number of regions and is on the official noxious weed lists in Oregon and Washington.

State- and county-sponsored efforts are encouraging the destruction of ivy in forests of the Pacific Northwest and the Southern United States. Its sale or import is banned in Oregon. Ivy can easily escape from cultivated gardens and invade nearby parks, forests and other natural areas.
What is Z-4-Hexadecenoic acid?
1.02.2.2.1 ( Z )-4-Hexadecenoic acid#N#The title compound ( Figure 3) is produced by the action of a Δ4 palmitoyl ACP desaturase found in some species of Umbelliferae, Araliaceae, and Garryaceae and is chain elongated to produce petroselinic (6 Z )- (6-octadecenoic) acid. 106 This acid accounts for as much as 85% of the total fatty acid content in these plants and is of interest to plant scientists because the shift of the double bond position from the more common Δ9 position raises the melting point by some 20 °C. A significant opportunity to place desaturase regioselectivity on a firm structural basis presented itself with the discovery that Δ4 palmitoyl ACP desaturase from Hedera helix (English ivy) was amenable to analysis by X-ray crystallography. 107 The outcome of this work was surprising. The structures of the Δ4 palmitoyl ACP desaturase and the original Δ9 stearoyl ACP desaturase are startlingly similar. Subtle differences were noted in residue conformation at the methyl terminus of the putative hydrophobic substrate binding site and at the ACP binding area near the opening of the active site. The tentative conclusion was that these modifications allowed a hexadecanoyl ACP substrate to penetrate the ivy Δ4 protein more deeply than is the case for the corresponding stearoyl ACP substrate and the castor Δ9 protein. Due to the lack of definitive data on the mode of substrate binding, it was important to examine the stereochemistry of Δ4 desaturase-mediated dehydrogenation. 108 This was accomplished by tracking the fate of deuterium atoms located on stereospecifically monodeuterated substrates, (4 S )- and (4 R )- [4- 2 H 1 ]-palmitoyl-ACP and (5 S )- and (5 R )- [5- 2 H 1 ]-palmitate-ACP. These compounds were prepared by a novel, general route involving nucleophilic opening of chiral terminal epoxides that are available in very high % ee. It was found that the introduction of the ( Z )-double bond between C4 and C5 of a palmitoyl substrate occurs with pro R enantioselectivity – a result which matches that obtained for a closely related homologue castor stearoyl-ACP Δ9 desaturase. These data suggest that despite the marked difference in the regioselectivity between the two enzymes, the stereochemistry of hydrogen removal is conserved. Of great interest would be the elucidation of the cryptoregiochemistry of the Δ4 desaturation.#N#Analysis of the X-ray structure of the ivy enzyme also yielded unexpected information on the diiron catalytic core in that the iron atoms were observed in the diferric oxidation for the first time. This allowed a direct comparison between the ligand coordination for the reduced and oxidized state and exposed carboxylate shifts that are characteristic of this class of enzyme. 109 While the mechanistic significance of these differences cannot be ascertained at this time, it is hoped that these data can be used to build up a consistent picture of the entire catalytic cycle from substrate binding to exit of product.
Where can I find Lichtensia viburni?
Lichtensia viburni can be found in the olive groves of many countries surrounding the Mediterranean basin (Spain, Southern France, Italy, ex Yugoslavia, Greece, Turkey, Israel, Algeria, Tunisia and Malta) where it is an occasional pest. Its most common host plants are Olea europaea (var. europaea and var. sylvestris ), Pistacia lentiscus and Hedera helix, although it has been reported on many plants belonging to different families ( Quaglia and Raspi, 1979b ). The biology of this species is apparently similar throughout the Mediterranean basin. It has been studied in detail on olive in Italy by Quaglia and Raspi (1979b).
