genetics and physiology of lead tolerance in Festuca ovina. by Colin Urquhart Download PDF EPUB FB2

Vegetative samples of F. ovina were collected from several populations in each of the chief lead-mining areas of Britain, and tested for tolerance to lead [cf. XXVIII, ]. There was no evidence of a clear division between tolerance and nontolerance, nor, on the other hand, was there a completely continuous range between the two extremes.

It is suggested that more than one type of tolerant Cited by:   Lead Tolerance and Accumulation in Hirschfeldia incana, a Mediterranean Brassicaceae from Festuca ovina, is an interesting experimental model to identify new genes involved in the molecular mechanisms of Pb accumulation and tolerance in plants.

The research was conducted to study the effect of NaCl priming and hydropriming on germination and early growth of Festuca arundinacea and Festuca ovina seeds under salinity stress.

First factor was plant species, the second was pre-treatment priming (NaCl priming with three concentrations, 15, 30 and 45 dS. Six grass species which differed in ability to grow on serpentine soils were assayed for root surface acid phosphatase activity in solutions of Ca, Mg, Ni, Cr III, Cr VI, and Zn at various concentrations.

The root surface phosphatases of relatively serpentine tolerant species (Festuca rubra, Festuca pratensis and Holcus lanatus) were unaffected by the external Ca concentration whereas Ca. Extremely high degrees of lead tolerance, measured by comparing rates of root extension in culture solutions, are reported from populations of Festuca ovina growing at two lead-mining sites (Westschacht and Keldenich-II) near Mechernich in the Eifel Mountains, Germany.

Oota, on RNA in developing plant cells; evidence cited suggests that "protein synthesis is coupled with de novo synthesis or at least the presence of RNA", which is also in some way connected with auxin activity. Due to its strong tolerance to stress and adversity, Festuca ovina L. survives well in various habitats, which range from acid soils, coastal dunes and cliffs to cold deserts and heavy metal soils.

Moreover, this species is abundant in Eurasia, ranges from the Arctic to the warm temperate zone, and is even found in outlying areas further south.

Protein turnover is generally regarded as one of the most important maintenance processes in plants in terms of energy requirements.

In this study, the contribution of protein turnover to the respiratory costs for maintenance in the roots of two grass species, the fast‐growing Dactylis glomerata L. and the slow‐growing Festuca ovina L., is evaluated.

Background: A horizontal gene transfer has brought an active nuclear gene, PgiC2, from a polyploid Poa species (P. palustris or a close relative) into the common grass sheep's fescue (Festuca ovina).

The donor and the receptor species are strictly reproductively separated, and PgiC2 occurs in a polymorphic state within F. ovina. The active gene copy is normally closely linked to a very similar. The development of vegetation (mainly the Violetum calaminariae Schwick.) in heavy metal‐contaminated areas depends on the metals mobility in soils and on metal availability for plants.

Moreover, the ability of plant populations to evolve metal tolerance is one of the most important characters which determines the structure, density and development of the vegetation in such areas. Specific internal chelation of the metal in qu estion was advanced as an explanation for the tolerance, the metal thereby being rendered innocuous.

Genetics of lead tolerance in Festuca ovina. However, some plant species tolerate the presence of Pb and, more interestingly, several species, including Noccaea caerulescens, Agrostis tennuis, or Festuca ovina, have developed the capacity to accumulate large amounts of lead in their root tissues with limited translocation to the aboveground parts (Vangronsveld et al., ).
