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...

Massarina ingoldiana occurs worldwide on a variety of dead plant substrates in aquatic habitats. This species has been accommodated in Massarina or Lophiostoma in Pleosporales, Dothideomycetes, but the validity of either of these taxonomic placements has not been confirmed with molecular data. In addition morphological variations occur among different populations of this species causing problem...

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 ...

Meloidogyne graminicola is one of the most harmful organisms in rice cultivation throughout world. This pest was detected for first time mainland Europe (Northern Italy) 2016 and subsequently added to EPPO Alert List. To date, few methods are available control M. new solutions required. In 2019, field trials using plants as trap crops were performed a Lombardy region where five plots three diff...

Brassica juncea Nonexpressor of pathogenesis-related genes 1 (BjNPR1) has been introduced into pearl millet male fertility restorer line ICMP451 by Agrobacterium tumefaciens-mediated genetic transformation. Transgenic pearl millet plants were regenerated from the phosphinothricin-resistant calli obtained after co-cultivation with A. tumefaciens strain LBA4404 harbouring Ti plasmid pSB111-bar-Bj...

Plant oxylipins, produced via the lipoxygenase (LOX) pathway, function as signals in defense and development. In fungi, oxylipins are potent regulators of mycotoxin biosynthesis and sporogenesis. Previous studies showed that plant 9-LOX-derived fatty acid hydroperoxides induce conidiation and mycotoxin production. Here, we tested the hypothesis that oxylipins produced by the maize 9-LOX pathway...

We have previously shown that the beneficial filamentous fungus Trichoderma virens secretes the highly effective hydrophobin-like elicitor Sm1 that induces systemic disease resistance in the dicot cotton (Gossypium hirsutum). In this study we tested whether colonization of roots by T. virens can induce systemic protection against a foliar pathogen in the monocot maize (Zea mays), and we further...
