Oogenesis and spermatogenesis of seven populations of Meloidogyne graminis and one population of M. ottersoni (formerly Hypsoperine spp.) were of the meiotic type. When males were abundant, reproduction was by amphirnixis. In most greenhouse cultures, however, males were rare and reproduction was by meiotic parthenogenesis. M. graminis and M. ottersoni are closely related to each other and to M...

One of the reasons for the progressive yield decline observed in aerobic rice production is the rapid build-up of populations of the rice root knot nematode Meloidogyne graminicola. These nematodes induce specialized feeding cells inside root tissue, called giant cells. By injecting effectors in and sipping metabolites out of these cells, they reprogramme normal cell development and deprive the...

Potassium (K), an important nutrient element, can improve the stress resistance/tolerance of crops. The application K in resisting plant-parasitic nematodes shows that treatment reduce occurrence nematode diseases and increase crop yield. However, data on K2SO4 induced rice resistance against root-knot Meloidogyne graminicola are still lacking. In this work, reduced galls plants delayed develop...

Meloidogyne graminicola is an economic yield loss causing major pest of rice globally. For managing this pest, biological control practices act as alternate strategy, it the most effective and economic. Plant growth promoting rhizospheric bacteria (PGPR) are significant because they benefit plants both directly indirectly by enhancing plant provides long lasting antagonistic effects against par...

Colletotrichum falcatum, a concealed fungal ascomycete causes red rot, which is a serious disease in sugarcane. It infects economically important stalk tissues, considered as store house of sugar in sugarcane. The study is to find genetic complexities of C. falcatum in establishing this as a stalk infecting pathogen and to decipher the unique lifestyle of this pathogen using NGS technology. We ...
