ANTH1101 - Agriculture Science Assignment, in the following document A recent study has shown that Sclerotinia stem rot, has great future opportunities for rapeseed oil. An article was published in the journal of plant pathology crops, which are significant to the farmers economically. The above-mentioned pathogen is different from the others, affecting the significant crops because maximum others have only one or a very thin range of hosts.

1AGRICULTURE SCIENCEFarming of oilseed rape Control of Sclerotinia stem rot on oilseed rape has great future opportunitiesM. C. Derbyshire and M. Denton-GilesMarch 3, 2016: A recent study has shown that Sclerotinia stem rot has great future opportunities for rapeseed oil. An article was published in the journal of Plant Pathology (DOI:10.1111/ppa.12517), based on a survey of 495 experts on this topic. It has been found that Sclerotinia is a type of pathogen, which has a wide list of hosts, approximately 400 crop species are infected by this particular fungus. The hosts include several such Getty image

2AGRICULTURE SCIENCEcrops, which are significant to the farmers economically. The above mentioned pathogen is different from the others, affecting the significant crops because maximum others have only one or very thin range of hosts. Some plant pathogen species have alternating genes. One is called ‘Gene Rich, Repeat Sparse’ and the other is called ‘Gene Poor, Repeat Rich’. Thus, they are known as two-speed genome. Amselem, Lebrun & Quesneville, (2015) said in the article ‘Whole genome comparative analysisof transposable elements provides new insight into mechanisms of their inactivationin fungal genomes.’ published in the journalBMC genomics,16(1), that the repeat rich regions in the fungi are inclined towards a procedure, called ‘Repeat InducedPoint Mutation (RIP)’. The repeat activity and RIP play a significant role in the development of secreted virulence proteins, called Effectors. Among top ten plant pathogenic fungi eight of the fungi were has a narrow range of pathogens, two of the fungi, Botryiscinerea and Fusarium graminearum have a broad range of hosts. Fusarium oxysporum was also included in the list is a complex species because it has a number of formae specials with various host specificities. According to do Amaral et al. (2012), there is a limitation on the knowledge of the broadrange host fungi, most of the information available and the knowledge the experts have are related to the fungi that has a narrow range of hosts. Increased mutation rates in repeat-rich regions of fungi arose from repeat induced point mutation. This particular activity is carried out in defense of excess TE activity, which can be harmful if not prevented or controlled. The analysis of the fungal genome marks the beginning of the investigation of the evolution of the molecular activity of fungal effector genes.
