Fusarium yellows

Tetraploid Thinopyrum elongatum (2n = 4x = 28) is a promising source of useful genes, including those related to adaptability and resistance to diverse biotic (Fusarium head blight, rust, powdery mildew, and yellow dwarf virus) and abiotic (cold, drought, and salt) stresses.

Members of the F. oxysporium species complex (FOSC) in the f. sp. apii (Foa) are pathogenic on celery and those in f. sp. coriandrii (Foci) are pathogenic on coriander (=cilantro). Foci was first reported in California in 2005; a new and highly aggressive race 4 of Foa was observed in 2013 in California.

The typical symptoms of the disease are yellowing of lower leaves, drooping, and wilting of plant. Sreedevi et al., (2009) reported that the presence of cultural and morphological variability among the Fusarium solani isolated from different areas of Karnataka state, India. In the present studies isolates of F. solani (Mart.) Sacc. collected from four districts of Assam were studied for the presence of cultural and morphological variations among these isolates.

Pea is one of the most important rabi pulse crops of India. Pea is being rich in protein are valuable for vegetable purpose. Fourteen isolates of Fusarium oxysporum f.sp.pisi from different districts of Manipur were studied for its cultural, morphological and pathogenic variability. The mycelia colour varied from white to light pink, purple and pale yellow colour. The radial growth of the isolates ranged from 5.4cm to 8.9cm at 8 days after inoculation at 26±10 0C in 90mm petriplates. Sporulation of all isolates showed moderate to profuse.

Biotic and abiotic stresses are major constraints in the production of groundnut. Among biotic stresses apart from bacterial and viral diseases, many fungal diseases are of economic importance. The major fungal diseases are Early leaf spot (Cercospora arachidicola), Late leaf spot (Cercosporidium personatum), Rust (Puccinia arachidis), Botrytis blight (Botrytis cinera), Aflarot/Yellow mould (Aspergillus flavus), Damping off (Pythium spp.

Rhizome rot and yellows caused by Fusarium oxysporum f. sp. Zingiberi, is a serious a serious soil-borne disease of ginger and found to be prevalent in the north-east region of India. Most of the plant disease resistance (R) genes encode a highly conserved nucleotide binding site and leucine-rich repeat structure (NBS-LRR).

Fusarium oxysporum infection leads to Fusarium-derived wilt, which is responsible for the greatest losses in flax (Linum usitatissimum) crop yield. Plants infected by Fusarium oxysporum show severe symptoms of dehydration due to the growth of the fungus in vascular tissues. As the disease develops, vascular browning and leaf yellowing can be observed.

Turmeric is one of the important spice crops grown in India. Root-knot nematode (Meloidogyne spp.) is a major problem, which causes galls/knots in the rhizomes and causes considerable yield loses. It also makes the way for the secondary infection by different pathogens like Pythium, Fusarium and Ralstonia in the soil. Yield losses due to nematode infestation are reported in turmeric-growing areas. A roving survey was conducted for incidence of root-knot nematode in turmeric during kharif season in 2016 at Belagavi, Bagalkot, Chamarajanagar and Kalburgi districts of Karnataka.

Endophytes are novel sources of natural bioactive compounds. This study seeks endophytes that produce the anticancer enzyme L-asparaginase, to harness their potential for mass production. Four plants with anticancer properties; Cymbopogon citratus, Murraya koenigii, Oldenlandia diffusa and Pereskia bleo, were selected as host plants. L-Asparaginase-producing endophytes were detected by the formation of pink zones on agar, a result of hydrolyzes of asparagine into aspartic acid and ammonia that converts the phenol red dye indicator from yellow (acidic condition) to pink (alkaline condition).
