Canola plant with its cotyledons and first true leaf. Upon emergence, four to 15 days after seeding, the seedling develops a short 1.25 to 2.50 centimetres (0.5 to 1.0 inch) stem. The cotyledons at the top of the hypocotyl (growing point) expand, turn green and provide food to the growing plant.

Read MoreIn botany, a stoma (from Greek στόμα, "mouth", plural "stomata"), also called a stomate (plural "stomates") is a pore, found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange.The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening.

Read More· Meiotic recombination promotes genetic diversity by shuffling parental chromosomes. As observed by the very first geneticists, crossovers inhibit the formation of another crossover nearby, an elusive phenomenon called crossover interference. Another intriguing observation is heterochiasmy, the marked difference in male and crossover rates observed in many species. Here, we show that …

Mosses grow on tree trunks, and horsetails (Figure 1) display their jointed stems and spindly leaves on the forest floor. Yet, seedless plants represent only a small fraction of the plants in our environment. Three hundred million years ago, seedless ...

Read MoreThese septa separate the viable compartment from hyphal segments devoid of a cytoplasm, resulting in the formation of regularly spaced empty sections (Lehmler et al., 1997; Steinberg et al., 1998). The nuclei travel to the centre of the cell and are positioned in a defined distance of about 10 μm from each other as well as about 50 μm from the tip ( Steinberg et al., 1998 ; Fuchs et al., 2005 ).
Read More· Pattern formation has long interested both theoretical biologists (1,2) and plant ecologists (3, 4). Theoretical studies have shown that local interactions coupled by dispersal can cause nonuniform distributions of organisms to develop in the absence of underlying heterogeneity.

Read MoreGrafting or graftage[1] is a horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion (/ˈsaɪən/) while the lower part is called the rootstock.
