Cassava mosaic disease

Bệnh khảm lá sắn (Cassava mosaic disease, CMD), do vi-rút thuộc họ Geminiviridae gây ra, là một trong 10 bệnh gây thiệt hại mùa màng lớn nhất trên thế giới. Trong nghiên cứu này, các mẫu lá sắn với bệnh tích khảm đặc trưng được thu thập tại Tây Ninh, Ninh Thuận và Củ Chi. Kết quả PCR xác định các mẫu dương tính với Sri Lanka cassava mosaic virus (SLCMV).

Cassava (Manihot esculenta Crantz.) is an important tuber cultivated in India. Cassava is vegetatively propagated through stem cuttings (setts). A mature plant with two stems will give about 12 to 20 normal sized (20 cm) setts after one year. Farmers are practicing 8-10 cm long cuttings from the mature part of stem and planted in vertical position in nursery bed at closer spacing of 5 cm. Under conventional system of propagation, 1250 to 1500 stems are required for planting one hectare of area.

Morphogenic culture systems are central to crop improvement programs that utilize transgenic and genome editing technologies. We previously reported that CMD2-type cassava (Manihot esculenta) cultivars lose resistance to cassava mosaic disease (CMD) when passed through somatic embryogenesis.

Cassava mosaic disease (CMD) is caused by a number of distinct begomoviruses under the family Geminiviridae. In Indian subcontinent, Indian cassava mosaic virus (ICMV) and Sri Lankan cassava mosaic virus (SLCMV) were reported to be associated with CMD. Although CMD is naturally transmitted by the whitefly (Bemisia tabaci Genn.).

Proteomics is becoming an increasingly important tool for the study of many different aspects of plant functions, such as investigating the molecular processes underlying hostpathogen interaction, plant physiology, development and differentiation. Cassava mosaic disease (CMD), caused by cassava mosaic virus (CMV), is the most serious disease in cassava. However, the molecular mechanisms underlying CMD in cassava during CMV infection is not yet clearly understood.
