Topic: Megaceros (botany)


  
  American Journal of Botany, 57, 1, January, 1970   (Site not responding. Last check: 2007-11-02)
Abstract: The pollination patterns of bees and butterflies were observed in an assemblage composed of 57 plants of Lythrum alatum and 30 plants of L. salicaria.
This condition is characterized by the presence in each cell of the gametophyte of only a single large chloroplast containing a "multiple" pyrenoid.
In two species of Megaceros the pyrenoid was observed to be composed of a highly subdivided thylakoid system of even greater complexity than the "multiple" pyrenoids of Phaeoceros.

 The Hornwort Genus Megaceros: The Australian Connection
Megaceros is a genus of hornwort found within the moister areas of Australia and neighbouring regions.
Typically found growing on rocks and soil banks in streams, Megaceros populations are spread throughout the moister areas of Australia, with an eastern distribution ranging from northern Queensland down to Tasmania.
Mature air-dried spores were removed from the capsules of Megaceros herbarium specimens originating from a variety of Australian populations and type specimens from Australia and the surrounding regions.

 New Zealand Anthocerotae (Hornworts)
Five to nine genera are recognised, including Anthoceros, Megaceros, Dendroceros, Phaeoceros (sometimes treated as a subgenus or partial synonym of Aspiromitus or Anthoceros), Folioceros, Notothylas and Nothoceros.
These are widely distributed in temperate and tropical latitudes; all genera found in tropics and subtropics; most found on moist mineral soil of banks and cliffs, among grasses, and along streams, from sea level to alpine elevations.
Sporophytes may reach lengths of 12 cm; first division of the zygote is by a longitudinal line (this is different from all other bryophytes); endothecium becomes the columella and the amphithecium produces the sporogenous layer and jacket; the sporogenous layer overarches the columella early in development.

 Ancient Life-History of the Earth
It is the ancient life-history of the earth, as revealed to us by the labours of palæontologists, with which we have mainly to do here; but before entering upon this, there are some general questions, affecting Geology and Palæontology alike, which may be very briefly discussed.
The study of the rock-masses which constitute the crust of the earth, if carried out in the methodical and scientific manner of the geologist, at once brings us, as has been before remarked, in contact with the remains or traces of living beings which formerly dwelt upon the globe.
Their study constitutes the science of palæontology; and though it is possible to proceed to a certain length in geology and zoology without much palæontological knowledge, it is hardly possible to attain to a satisfactory general acquaintance with either of these subjects without having mastered the leading facts of the first.

This aim is indeed the more of an obligation upon us from the very perfection of our district, with its natural boundaries, of a size neither too large for us to compass nor too small or uniform to be interesting, isolated yet easily accessible, a perfect district and a natural region.

However great its physical advances may be, Geology remains imperfect till it is wedded with Palaeontology,[2] a study which essentially belongs to the vast complex of the Biological Sciences, but at the same time has its strictly geological side.
It is the ancient life-history of the earth, as revealed to us by the labours of palaeontologists, with which we have mainly to do here; but before entering upon this, there are some general questions, affecting Geology and Palaeontology alike, which may be very briefly discussed.
Their study constitutes the science of palaeontology; and though it is possible to proceed to a certain length in geology and zoology without much palaeontological knowledge, it is hardly possible to attain to a satisfactory general acquaintance with either of these subjects without having mastered the leading facts of the first.

In a collaboration with Dr Vaughn, we will identify the molecular basis of the pyrenoid in hornworts, where there is a progression of species which vary on their reliance on a CCM.
Having firstly characterised the magnitude and extent of any CCM activity from a range of hornworts, (such as in the genus Megaceros), we will analyse rbcL sequences and Rubisco kinetic characteristics.
Ultimately, the aim would be to identify genes that determine pyrenoid structure; informed by developments from the well-characterised Chlamydomonas system, we will identify genes associated with the formation and operation of the pyrenoid and CO concentrating mechanism.

She also described the excellent research facilities at RBGE for bryology, including the bryophyte herbarium and library, which are available for consultation by BBS members.
Together, Britain and Italy have remarkably good bryophyte floras for our kind of work; most groups are well represented and can be fixed immediately after collection.
