(Jones, 1914) “It required the plague of the potato disease and the example of the Irish famine finally to focus attention upon the fundamental problem ‑ the relation of the mildew to the sick potato plant, of the smut and rust fungi to the infected grain ‑ the problem of parasitism." From 1846- 1850 Ireland population was dropped by 25% because of blighting potato had spread. That coasted Ireland in 1846, £3,500,000 because potatoes was one of the essential harvest’s income for the country, Truman, (2013). Thus, plants science has gotten more attention from scientists to struggle any sudden disasters on plants. However, organisms are divided to many kingdoms. All those affected each ...view middle of the document...

It spreads into the plants’ cell and it makes a swelling at the intersection on roots and stems and soil, (Vidaver and Lambrecht, 2014). All those effects are relying on humidity and temperature. Bacteria survive by soil surface, in or on seeds, in water, inanimate objects, and in or on insects. From a long time it is accounted as one enemy which threaten plants life. It caused economy’s disasters because of that there are new studies to change bacteria structure to be benefits for healthy plants instead of harmful (Vidaver and Lambrecht, 2014). All these bad effects of bacteria impact plant diseased, then other organisms’ lives.
The second pathogen on plants is viruses. It spreads between plants quickly and causes plants diseases. The virus is nucleic acid which has the genetically information is surrounded by protein to save the nucleic acid for thousands of years, (Gergerich1 and Dolja, 2006). Viruses are able to affect all organisms. The huge case with viruses is that viruses have spread between many kinds of plants very quickly. For example, cucumber mosaic viruses affects 85 plants’ families, (Gergerich1 and Dolja, 2006). As a result scientists or farmers cannot stop the negative effects until viruses has destroyed almost all of harvest and force the plants to produce its protein. It is good to know that some plants prevent viruses to make any changes but others accept it. If the plants accept viruses, they will have many symptoms of diseases. Those symptoms depend on environments, host plants, and viruses. To illustrate, there are many symptoms let us diagnosis the diseased plants such as leaf symptoms like yellowing, flower symptoms like change flowers’ color, and fruits and vegetable...

For Better or Worse? Essay

645 words - 3 pages GMOs, or genetically modified organisms, are plants and animals that have had their DNA changed. The organisms have been given genes from other living things to modify them to resist things such as insects, herbicides, and diseases.

Of the 300,000 plant species worldwide, a little over 3,000 of these plants have been used as a source of food. Close to 300 of these species are grown around the world today and only 12 of these plants make up about 90 percent of the food sources in our world. These 12 include the grains: rice, wheat, maize (corn), sorghums

The effects climate change has on agriculture and livestock

1042 words - 5 pages which is an important factor to induce crop growth. Climate change rarely causes plant disease but instead enhances it. The effects of climate change on plants are due to the type of crop and the region it is grown. Diseases such as fungal disease are dispersed through wind and this helps to spread plant diseases. The rise in the temperature can help to increase plant diseases which may result in a decrease of crop production. According a
