What is the Difference Between Alternaria Brassicae and Alternaria Brassicicola

Thekey differencebetween Alternaria brassicae and Alternaria brassicicolais thatAlternaria brassicaeis a fungal plant pathogen that infects plants belonging to the genus ofBrassicaand roses, whileAlternaria brassicicolais a fungal plant pathogen that infects plants only belonging to the genus ofBrassica.

Alternaria brassicaeandAlternaria brassicicolaare two fungal plant pathogens that cause diseases specifically to plants of the genusBrassicasuch as cabbage, cauliflower, etc. However, they cause different diseases. Both these species belong to the fungal genusAlternaria.The species in this genus are mainly fungal plant pathogens andallergensfor humans. The species in this fungal genus grow indoors and cause hay fever orhypersensitivityreactions. Sometimes, these allergic reactions can lead to asthma as well.

What is Alternaria Brassicae?

Alternaria brassicaeis a fungal plant pathogen that belongs to the genusAlternaria. It is able to infect mostBrassicaspecies, including important crops such as broccoli, cabbage, and oil seed grape. In younger plants, this species causes more severe damping off, while in older plants, it causes less severe leaf spot symptoms.A. brassicaeproduces a number of toxins called destruxins, which are toxic to plants from a number of genera of dicotyledons. This species affects host species at all stages of growth, including the seed stage.

TheconidiophoresofA. brassicaeproduce asexual spores, which are around 160-200 µm long in size. Normally, in this fungal species, proper sporulation occurs between the temperatures of 8 to 24^oC. Mature spores develop after 24 to 14 hours. The optimum temperatures for the sporulation process are between 16 and 24^oC. Moreover, the time taken to complete sporulation ranges from 12 to 14 hours for this species. Furthermore,A. brassicaecan be controlled by crop rotation, using resistance varieties,fungicides, and use of biological control (Streptomyces arabicus).

What is Alternaria Brassicicola?

Alternaria brassicicolais a fungal plant pathogen that belongs to the genusAlternaria. It predominantly affects species ofBrassica.答:brassicicolamainly causes damage to Cole plants such as broccoli, cabbage, cauliflower, brussel sprouts, and Chinese cabbage.答:brassicicolasporulates normally in a temperature range of 8 to 30^oC. Their spores are around 100-200 µm long in size. The mature spores develop after 14 and 43 hours for this species, respectively. Moreover, optimum temperatures for proper sporulation range between 18 and 30^oC for this species.

The time period taken to complete the sporulation for答:brassicicolais 13 hours. Furthermore, it also contributes to various respiratory allergic conditions, such as asthma and rhinoconjunctivitis in humans. The infection of this fungal species can be treated through pre-treatment of seeds with fungicides such as Iprodione and Strobilurins, biological control through antagonistic fungi such asAureobasidium pullulansandEpicoccum nigrum, use of plants such as plantsc . fenestratumandPiper betle, the active compound a, and ethanol extracts from the dried roots ofSolanum nigrum.

What are the Similarities Between Alternaria Brassicae and Alternaria Brassicicola?

• A. brassicaeand答:brassicicolaare two fungi of the genusAlternaria.
• Both species are plant pathogens mainly affecting plants of the genusBrassica.
• They tend to grow in moist and damp environments.
• They affect host species at all stages of growth, including the seed stage.
• These species mainly reproduce sexually by making conidia.
• Both species are able to cause plant disease called black spot leaf disease.

What is the Difference Between Alternaria Brassicae and Alternaria Brassicicola?

A. brassicaeis a fungal plant pathogen that infects plants belonging to the genus ofBrassicaand roses, while答:brassicicolais a fungal plant pathogen that infects plants that only belong to the genus ofBrassica. Thus, this is the key difference betweenAlternaria brassicaeandAlternaria brassicicola. Furthermore,A. brassicaehas a genome of approximately 3.4 Mbp in size. On the other hand,答:brassicicolahas a genome of approximately 3.1 Mbp in size.

Summary – Alternaria Brassicae vs Alternaria Brassicicola

Alternariais a genus of Deuteromycetes fungi. There are about 299 species in the genus.A. brassicaeand答:brassicicolaare two fungal plant pathogens belonging to this genus.A. brassicaeand答:brassicicola可以影响宿主物种在增长的所有阶段,我呢ncluding seeds. Both these species are the major plant pathogens that cause black spot leaf disease in plants. However,A.brassicaeis a fungal plant pathogen that is responsible for black spot leaf disease on plants belonging to the genus ofBrassicaand roses. On the other hand,答:brassicicolais a fungal plant pathogen responsible for black spot leaf disease on plants that only belong to the genus ofBrassica. So, this summarizes the difference between Alternaria brassicae and Alternaria brassicicola.
