The total phenol content of four common paddy cultivars Odisha namely Abhisek (R), Manik (MR), Bas-12 (S) and Lalat (HS) were studied under pot culture condition in the net house following CRD design different treatments using biofertilizer Azospirillum. brasilense alone or combinations against rice root-knot nematode Meloidogyne graminicola. objective work was to study quantitative changes phe...

Root-knot nematodes (RKNs), Meloidogyne spp, are found in all temperate and tropical areas, and are among the most damaging plant pathogens worldwide. M. graminincola is an economically important root parasite on upland, lowland and deepwater rice. FMRFamide-like peptides (FLPs) play significant role as neurotransmitters or neuromodulators in the nervous system and proposed as one of the import...

Meloidogyne graminicola merupakan salah satu nematoda parasit penting pada tanaman padi. M. menyebabkan gejala puru akar sehingga pertumbuhan terhambat dan terganggu. Pengendalian sangat dilakukan agar kerusakan padi penyebarannya dapat ditekan. Penelitian ini bertujuan untuk menguji potensi bakteri endofit dalam mengendalikan (NPA) Empat isolat asal padi, yaitu Si33, Si2, Sp24, GH1, kentang G0...

Recent linyphiid collections from Laos as well as some additional specimens from Thailand and West Malaysia are examined. Six species and two genera are described as new to science: Bathyphantes paracymbialis n. sp., Nematogmus asiaticus n. sp., Theoa hamata n. sp.; Asiagone n. gen. is erected for Asiagone signifera n. sp. (type species) and A. perforata n. sp.; Laogone n. gen. is established f...

Brassinosteroids (BRs) are a unique class of plant steroid hormones that orchestrate myriad growth and developmental processes. Although BRs have long been known to protect plants from a suite of biotic and abiotic stresses, our understanding of the underlying molecular mechanisms is still rudimentary. Aiming to further decipher the molecular logic of BR-modulated immunity, we have examined the...

Photodynamic inactivation (PDI) is an efficient approach for the elimination of a series of microorganisms; however, PDI involving phytopathogenic filamentous fungi is scarce in the literature. In the present study, we have demonstrated the photoinactivating properties of five cationic meso-(1-methyl-4-pyridinio)porphyrins on conidia of the phytopathogen Colletotrichum graminicola. For this pur...

Plant-parasitic nematodes of the genus Meloidogyne, known as root-knot nematodes (RKN), have an important economic impact on golf course turfgrasses. The most prevalent RKN species associated with grasses are M. chitwoodi, M. graminicola, M. graminis, M. incognita, M. marylandi, M. microtyla, M. minor, M. naasi and M. sasseri. In 2010, slight thickening of the roots and RKN females with unusual...

Phylogenies were inferred from nearly complete small subunit (SSU) 18S rDNA sequences of 12 species of Meloidogyne and 4 outgroup taxa (Globodera pallida, Nacobbus abberans, Subanguina radicicola, and Zygotylenchus guevarai). Alignments were generated manually from a secondary structure model, and computationally using ClustalX and Treealign. Trees were constructed using distance, parsimony, an...

Pythium species were isolated from diseased samples of creeping bentgrass and annual bluegrass. Among fourteen isolates from decayed roots and crowns, seven were P. graminicola, five were P. torulosum and two were P. ultimum. These species were identified by comparison of cultural and morphological characteristics to literature and reference isolates. In a tissue culture plate assay for quantif...

A root-knot nematode, Meloidogyne floridensis n. sp., is described and illustrated from peach originally collected from Gainesville, Florida. This new species resembles M. incognita, M. christiei, M. graminicola, and M. hispanica, but with LM and SEM observations it differs from these species either by the body length, shape of head, tail and tail terminus of second-stage juveniles, body length...
