Background Plant infection models provide certain advantages over animal models in the study of pathogenesis. Duckweeds (Lemnoideae) are a group of higher aquatic plants belonging to the Araceae and commonly found in freshwater habitats. This plant has the ability to reproduce rapidly, it can double in just 16 hours - 2 days, depending on its growing environment. Duckweeds are ideal material for physiological, biochemical, and genomic studies because of their direct contact with medium, rapid growth and relatively small genome sizes. Ans: Air chambers in the stems of the many submerged plants to stay upright in water. Development of such a plant model is needed to better illustrate host-pathogen interactions. Bougainvillea. The re-colonization of aquatic habitats by angiosperms has presented a difficult challenge to plants whose long evolutionary history primarily reflects adaptations to terrestrial conditions. Example: Water starwort submerged in a marsh pond. Lemna minor is a floating freshwater aquatic plant, with one, two, three or four leaves each having a single root hanging in the water. Thus K-selected populations are less able to take advantage of particular opportunities to expand (than r-selected pop­ulations). Adaptations that improve competitive ability and efficiency of resource utilisation are selected. Once considered a weed of cornfields, the Common poppy is now in decline due to intensive agricultural practices. Two principal methods are found. The duckweeds have fascinated many generations of biologists since 1960s because of their simplicity of body structure and extremely fast vegetative reproduction.

Leaves are oval, 1–8 mm long and 0.6–5 mm broad, light green, with three (rarely five) veins and small air spaces to assist flotation. If colonies cover the surface of the water, then oxygen depletion and fish kills can occur. In particular, Kellie is interested in the adaptive traits of duckweed species to allow their global colonisation covering diverse light and water environments. Many of these characteristics are adaptations for surviving drought. The chief characteristics that make duckweeds ideal for waste-to-energy conversion are their rapid growth rate, easy harvesting potential, and ability to grow directly on existing wastewater sites. Many aquatics must complete vital stages of their life cycle on the water surface by means of floating or emergent leaves and flowers. Imbibition & Power Of Plants 4. Grace, 1993 ).

This occurs through late summer flowering or the production of starch-filled structures or turions which are denser than the fronds so the plants sink to the bottom of the water body and become embedded in dried mud. It is possible that PS or DHS-effluent contained some specific substrates promoting the growth of Rhizobiales. 2011, 2012; Soda et al. Also known as "bayroot", they arose from within the arum or aroid family, so often are classified as the subfamily Lemnoideae within the family Araceae. Relative growth rates (RGR), doubling times (DT) and relative weekly yields (RY) of 39 clones (ecotypes) from 13 species representing all five genera of duckweeds were determined under standardised cultivation conditions. Duckweeds - for many aquatic animals like ducks and snails, a treat, but for pond owners, sometimes a thorn in the side. Chemicals Of Living Systems 2. Talking about the physical characteristics, duckweeds are lack of leaves and stems. Duckweed are small green plants that float atop of water and their roots hang below. The small size of duckweed helps it to spread easily in slow moving waters and attach to duck feathers and feet to be moved. Duckweed is a modified stem, called a frond. The seeds sink to the bottom of the body of water when the plant dies. Growing and sourcing. Wetland plant adaptations. Scientific name: Papaver rhoeas.
