High levels of genetic variability and inbreeding in two Neotropical dioecious palms with contrasting life histories. (1/7)

We characterized the population genetics of two Neotropical dioecious palm species of Chamaedorea with contrasting life strategies from the region that is both the northernmost extent and most species rich of the genus. Chamaedorea tepejilote is a common, wind-pollinated arboreal understory palm. Although most adult plants reproduce each year, only a few individuals produce the majority of flowers and seeds. Chamaedorea elatior, conversely, is an uncommon climbing subcanopy palm with entomophilous flowers (insect-pollinated characteristics). Most of the mature palms do not reproduce in consecutive years and fruiting is episodic. Isozymes with a total of 107 alleles for 27 loci of 17 enzymes from six populations were assessed. For both species, co-occurrence of high levels of genetic variation and homozygosity was observed (C. tepejilote: He: 0.385-0.442, f: 0.431-0.486; C. elatior: He: 0.278-0.342, f: 0.466-0.535). Genetic differentiation of C. elatior was much lower (theta=0.0315) than that for C. tepejilote (theta=0.152). The contrast in differentiation may be influenced by differences in the spatial scale of the genetic neighborhoods of the two species. The simultaneous maintenance of inbreeding and of a large number of alleles within the populations is attributable to the low and variable number of mating pairs. Demographic studies indicate that this pattern could be explained by low reproductive frequency among individuals and over years in C. elatior and by reproductive dominance in C. tepejilote.  (+info)

DNA barcoding in the cycadales: testing the potential of proposed barcoding markers for species identification of cycads. (2/7)

Barcodes are short segments of DNA that can be used to uniquely identify an unknown specimen to species, particularly when diagnostic morphological features are absent. These sequences could offer a new forensic tool in plant and animal conservation-especially for endangered species such as members of the Cycadales. Ideally, barcodes could be used to positively identify illegally obtained material even in cases where diagnostic features have been purposefully removed or to release confiscated organisms into the proper breeding population. In order to be useful, a DNA barcode sequence must not only easily PCR amplify with universal or near-universal reaction conditions and primers, but also contain enough variation to generate unique identifiers at either the species or population levels. Chloroplast regions suggested by the Plant Working Group of the Consortium for the Barcode of Life (CBoL), and two alternatives, the chloroplast psbA-trnH intergenic spacer and the nuclear ribosomal internal transcribed spacer (nrITS), were tested for their utility in generating unique identifiers for members of the Cycadales. Ease of amplification and sequence generation with universal primers and reaction conditions was determined for each of the seven proposed markers. While none of the proposed markers provided unique identifiers for all species tested, nrITS showed the most promise in terms of variability, although sequencing difficulties remain a drawback. We suggest a workflow for DNA barcoding, including database generation and management, which will ultimately be necessary if we are to succeed in establishing a universal DNA barcode for plants.  (+info)

Cycadophyta : - Cycadophyta: There are approximately 350 species of plants in this division which, by the shape of their trunks and leaves, remind palm trees but they have nothing to do with them. It is believed that they already existed about 300 million years ago, but only some remains have been found dating 230 million years ago. They are very old trees that were very abundant in the Jurassic. Today you can find them in the wild in Southeast Asia, Southeast Africa, and Southeast Australia, Central America, Florida and the Caribbean countries. Among the trees included we can mention three families of cycads (Cycadeceae), such as Cycas revoluta, the zamias (Zamiaceae), a family containing the Encephalartos, such as Encephalartos horridus. The third family is the Stangeriaceae, within which there are two genders Stangeria and Bowenia. - Ginkgophyta: - Gingkgophyta: The ginkgo is the sole representative of this division of gymnosperms.

It has a subterranean caudex and unique multi-divided pinnae. ===History: === This species was described in 1959 by (the late) Dr L. A. S. Johnson, when he undertook a reclassification of the nomenclature of Australian cycads. Dr Johnson (a former Director of the Royal Botanic Gardens Sydney) found that M. stenomera, which had not been previously distinguished from M. heteromera, warranted recognition as a separate and distinct species. It was named after its narrow divided leaflets. ===Distribution Range: === M. stenomera grows in north-western New South Wales in an area centred principally around Mt Kaputar, which is the highest point of the Nandewar Range. Mt Kaputar is located approximately 50 km east of Narrabri. M. stenomera also grows in sandy soil on the plains nearer ...

The tRNALeu (UAA) intron has been recorded in the plastid genome of many algae and land plants and was the first intron to be discovered in cyanobacteria. In all known cases it interrupts the tRNALeu anticodon loop at a conserved position (U-intron-AA). Cyanobacteria are a diverse group of photosynthetic prokaryotes, some involved in symbiotic associations with a wide range of organisms. The most studied associations are those with plants, where strains of Nostoc are the common cyanobacterial partner. In this thesis two aspects of the biology of the cyanobacterial tRNALeu (UAA) intron are focused: first, the use of the intron as a genetic marker for studying the diversity and specificity of two cyanobacterial symbiosis (bryophytes and cycads) and second, the evolutionary patterns of the intron by using the unique data set generated from the diversity analysis.. From the studies, many different Nostoc strains are involved in the two symbiotic associations, although no variation was observed ...

The horseshoe crab is just one example of numerous living fossils or animals that have not changed for aeons of time. The most famous living fossil is the Coelacanth (Latimeria chalumnae) that was thought to be a link between fish and amphibians. Unlike "ordinary" fish, the Coelacanth gives birth to live offspring. Yet, the Coelacanth, dubbed the dino fish, is clearly a fish and not a half mammal. Evolutionists believed it used its fins to walk on the seabed but observations have shown this to be false. Scientists suspected that it became extinct some 65 million years ago, but in 1938 a living specimen was caught off the coast of Madagascar and since then several others have also been sighted living ...

Third day, however, Kate got very fussy with her mouth, tossing her head and jawing a lot, even balking a little. After only ten minutes I climbed off, and, on checking her mouth, found that her lower jaw had hard swellings just below her first molars. Upon checking with the vet it was determined that the lumps were actually her adult molars coming in, but that the baby teeth--caps--above them had not yet been knocked off to make way for them to grow up, so they were pushing down into the jaw. He felt they werent far enough along for him to knock out yet, so I decided she could go back into the pasture until next spring--she was only two, after all! And shes had all the "start" I could want for a baby. The only thing more I might have done this first summer would have been some easy trail rides around the neighbors cattle pasture.. ...
The reproductive organs of some plants self-heat, release scent, and attract pollinators. The relations among these processes are not well understood, especially in the more ancient, nonflowering gymnosperm lineages. We describe the influence of plant volatiles in an obligate pollination mutualism between an Australian Macrozamia cycad (a gymnosperm with male and female individuals) and its specialist thrips pollinator, Cycadothrips chadwicki. Pollen-laden thrips leave male cycad cones en masse during the daily thermogenic phase, when cone temperatures and volatile emissions increase dramatically and thrips are repelled. As thermogenesis declines, total volatile emissions diminish and cones attract thrips, resulting in pollination of female cones. Behavioral and electrophysiological tests on thrips reveal that variations in b-myrcene and ocimene emissions by male and female cones are sufficient to explain the observed sequential thrips repellence (push) and attraction (pull). These dynamic ...

Gar. These freshwater fish favor warm water; theyre generally found in the southern U.S., Central America, Mexico and the West Indies. Like bowfins, the long-jawed gars are vicious and will eat other fish. Theyre also apt to simply attack any fish in their way, even if they dont intend to eat them. Fun facts: Dont eat gar eggs - they can kill humans and other warm-blooded vertebrates. Gars themselves are also inedible. ...
Ginkgo biloba - This is a living fossil, a tree thought to be long extinct, but now known to survive in the wild in a very small region of China. The tree is upright, columnar and has flat, fan-shaped mid-to yellow-green leaves which turn golden in the fall. Height to 100 feet; spread 25 feet.

Cycasin is a carcinogenic and neurotoxic glucoside found in cycads such as Cycas revoluta and Zamia pumila. Symptoms of poisoning include vomiting, diarrhea, weakness, seizures, and hepatoxicity. In metabolic conditions, cycasin is hydrolyzed into glucose and methylazoxymethanol (MAM), the latter of which dissociates into formaldehyde and methyl-diazonium. It induces hepatotoxicity and Zamia staggers, a fatal nervous disease affecting cattle resulting from browsing on the leaves or fruit of cycads. Cycasin is found in all known cycad genera and is distributed throughout the body of the plant, but with the highest concentration in the seeds. It is one of several toxins found in cycad plants, along with the neurotoxic amino acid BMAA. The origin and biological role of these toxins is unknown, as there does not appear to be a statistically significant correlation between the concentration of toxic material and the types of herbivory observed in animals consuming the plants. The enzyme ...

This is a unique species native to the West Coast of Africa along a narrow strip from southern Angola through the northern half of Namibia. It is sometimes referred to as a "living fossil", because it has changed very little over eons. It is the only species in its Genus, which is the only Genus in the family Welwitschiaceae, which is the only family in the Order Welwitschiales. It was discovered by the Western world by Friedrich Welwitsch in 1859. It has twocotlydeons (first leaves on seed-bearing plants), and then followed in growth by only two more permanent leaves, perpendicular to the cotlyedons. Those two leaves are what is visible on the surface, and they never stop growing while the plant lives. They simply grow longer and longer, with them slowly getting wider as the plant ages. ...

But if youre after two cool tidbits, know that the Australian Lungfish is essentially a living fossil. Fossilized evidence of its family members date back to the Devonian, and the Australian Lungfish itself has remained relatively unchanged for nearly 100 million years! There are five other Lungfish species still alive, and one of their closest lobe-finned relatives is the Coelacanth. Lobe-Finned fish are especially notable because it is from them that tetrapods eventually evolved ...
are seed-bearing vascular plants, such as cycads, ginkgo, yews and conifers, in which the ovules or seeds are not enclosed in an ovary. The word "gymnosperm" comes from the Greek word gymnospermos, meaning "naked seeds". Gymnosperm seeds develop either on the surface of scale or leaf-like appendages of cones, or at the end of short stalks. The largest group of living gymnosperms are the conifers. ...

Phylogenetic reconstruction is fundamental to study evolutionary biology and historical biogeography. However, there was not a molecular phylogeny of gymnosperms represented by extensive sampling at the genus level, and most published phylogenies of this group were constructed based on cytoplasmic DNA markers and/or the multi-copy nuclear ribosomal DNA. In this study, we use LFY and NLY, two single-copy nuclear genes that originated from an ancient gene duplication in the ancestor of seed plants, to reconstruct the phylogeny and estimate divergence times of gymnosperms based on a complete sampling of extant genera. The results indicate that the combined LFY and NLY coding sequences can resolve interfamilial relationships of gymnosperms and intergeneric relationships of most families. Moreover, the addition of intron sequences can improve the resolution in Podocarpaceae but not in cycads, although divergence times of the cycad genera are similar to or longer than those of the Podocarpaceae genera.

Vascular plants - The Full WikiVascular plants - The Full Wiki

The most abundant compound in all plants, as in all life, is water which serves an important role in the various processes taking place. Transpiration is the main process a plant can call upon to move compounds within its tissues. The basic minerals and nutrients a plant is composed of remain, generally, within the plant. Water is constantly lost from the plant through its stomata to the atmosphere.. Water is transpired from the plants leaves via stomata, carried there via leaf veins and vascular bundles within the plants cambium layer. The movement of water out of the leaf stomata creates, when the leaves are considered collectively, a transpiration pull. The pull is created through water surface tension within the plant cells. The draw of water upwards is assisted by the movement of water into the roots via osmosis. This process also assists the plant in absorbing nutrients from the soil as soluble salts, a process known as absorption. Surprisingly, the movement of water upwards requires very ...

The algae comprise several different groups of organisms that produce energy through photosynthesis. The most conspicuous are the seaweeds, multicellular algae that often closely resemble terrestrial plants, found among the green, red, and brown algae. These and other algal groups also include various single-celled creatures and forms that are simple collections of cells, without differentiated tissues. Many can move about, and some have even lost their ability to photosynthesize; when first discovered, these were considered as both plants and animals. The embryophytes developed from green algae; the two are collectively referred to as the green plants or Viridaeplantae. The kingdom Plantae is now usually taken to mean this monophyletic group, as shown above. With a few exceptions among the green algae, all such forms have cell walls containing cellulose and chloroplasts containing chlorophylls a and b, and store food in the form of starch. They undergo closed mitosis without centrioles, and ...
