Estudo Comparativo da Biologia de Meloidogyne enterolobii (= M. mayaguensis) e Meloidogyne javanica em tomateiros com gene Mi

Abstract: In order to know the host parasite relationship of M. enterolobii in plants with resistance to nematodes, comparative studies of the biology of M. enterolobii and M. javanica in tomato with the Mi gene were conducted. The experiment was set up in a two-by-two factorial design consisting of two varieties of tomato ('Magnet' and 'Helper M') root were collected at 3, 10, 17, 24 and 31 days after inoculation, stained with acid fuchsin, and dissected on stereomicroscope in order to observe the different developm… Show more

“…Aos 31 DAI, M. javanica multiplicou apenas na cultivar sem o gene Mi (Rutgers), enquanto M. enterolobii multiplicou em ambas as cultivares (com e sem o gene Mi de resistência). Vale ressaltar que observações realizadas por diversos autores demonstram que a capacidade de M. enterolobii de vencer a resistência genética é uma característica intrínseca dessa espécie (PROT, 1984;RODRIGUEZ, 2000;GUIMARÃES et al, 2003;CARNEIRO et al, 2006;WESTERICH, 2011). A importância de M. enterolobii também foi relatada por RODRIGUEZ et al (2007), os quais consideram essa espécie como a mais perigosa dentro do gênero Meloidogyne.…”

“…In relation to gall number, the ideal phenotypic reaction from the resistance breeding standpoint is an immunity-like response characterized by the complete absence of root galls and giant cells. The presence of giant cells in the vascular cylinder induced by nematode attack is the main factor restricting water flow and proper nutrient uptake in susceptible plants (Westerich et al, 2011).…”

“…The Meloidogyne females can lay eggs for up to three weeks with the average number of around 400 to 500 eggs; in some circumstances, the female lays up to 2,000 eggs (Taylor & Sasser, 1978). Development and life cycle completion of M. enterolobii were observed even in roots of tomato genotypes with the Mi-1 gene (Yang & Eisenback, 1983;Westerich et al, 2011).…”

“…Recently, another species, Meloidogyne enterolobii, although it occurs less frequently in relation to M. incognita and M. javanica, is becoming increasingly important, since many reported melon genotypes as resistant to major root-knot nematodes show no resistance to this species (Brito et al, 2007;Cantu et al, 2009;Kiewnick et al, 2009;Eppo, 2011;Melo et al, 2011;Westerich et al, 2011;Castagnone-Sereno, 2012;Singh et al, 2013).…”
