Of the world's known species of myrmecochores, plants which provide food bodies to induce ants to disperse their seeds, many are found in the dry sclerophyll vegetation of Australia. Here we present data and observations on myrmecochory on the West Head, and area of dry sclerophyll ...
Of the world's known species of myrmecochores, plants which provide food bodies to induce ants to disperse their seeds, many are found in the dry sclerophyll vegetation of Australia. Here we present data and observations on myrmecochory on the West Head, and area of dry sclerophyll vegetati...
However, there is some additional modulative, direct effect on size by low temperature. Alpine plants that survive in low-altitude rock gardens indeed grow taller than their relatives in the wild. But plants grown in such rock gardens are commonly of montane origin, because most typical alpine ...
Seeds and pollen—two critical adaptations to drought, and to reproduction that doesn’t require water—distinguish seed plants from other (seedless) vascular plants. Both adaptations were required for the colonization of land begun by the bryophytes and their ancestors. Fossils place the earliest dis...
As the plant matures, it takes on a purple-reddish hue, after which it turns crispy and light brown as the seeds disperse. The stiff awns remain on the seeds and aid in dispersal. They also cause injury to animals that dare consume them, poking into the soft tissues of their mouths. ...
There is a major concern that traditional medicinal knowledge may be lost if there are not sufficient trainees or suitable successors. Among the common medicinal plants, most are herbaceous and the Shui typically use the whole plant in their medicines. There are 85 different recorded diseases ...
Numerous animals have coevolved with plants. Many animals pollinate flowers in exchange for food in the form of pollen or nectar. Many animals disperse seeds, often by eating fruit and passing the seeds in their feces. Myrmecophytes are plants that have coevolved with ants. The plant provides...
Seeds Don’t All Ripen At The Same Time Most plants flower over a number of days or weeks and their corresponding seeds also ripen over a period of time. This is important for the plant since it increases the chance that some will survive and grow into seedlings. ...
Promoter regulatory elements may also include certain enhancer sequence elements that improve transcriptional or translational efficiency. By “tissue-specific” promoter is meant promoter elements responsible for gene expression in specific cell or tissue types, such as the leaves or seeds (i.e., ...
The screen disperses the particles so that they are not delivered to the recipient cells in large aggregates. For the bombardment, cells in suspension are preferably concentrated on filters or solid culture medium. Alternatively, immature embryos or other target cells may be arranged on solid ...
