Potentiality of Native Pseudomonas spp. in Promoting Sugarcane Seedling Growth and Red Rot (Colletotrichum falcatum went) Management

چکیده
Sugarcane is an important cash crop grown in tropical and sub-tropical regions of the world. India is the second largest producer of sugar after Brazil and accounts for 16 per cent of world production (GOI, 2015). In Andhra Pradesh, sugarcane is grown in 1.39 lakh hectares with a production of 99.8 lakh tones. However, the sugarcane productivity (71 tonnes/ha) is very low compared to states like Tamil Nadu, West Bengal, Kerala and Karnataka (GOI, 2017). Sugarcane productivity in Andhra Pradesh is majorly hampered by several biotic stresses of which red rot caused by the fungus, Colletotrichum falcatum Went, is a serious threat to sugarcane production under irrigated conditions. The pathogen infects mature stalks of sugarcane; leaf midribs and cause rot of planting material which results in substantial losses in crop yield and sugar quality (Rao, 2004). This disease is responsible for phasing out of several ruling cultivars previously.

Isolation, characterization, and effect of fluorescent pseudomonads on micropropagated sugarcane.
In this study, we report on the isolation, identification, and characterization of seven fluorescent pseudomonads isolated from the roots, shoots, and rhizosphere soil of sugarcane and their impacts on the growth of sugarcane plantlets. 16S rRNA gene sequence of five isolates showed close homology with Pseudomonas putida, one with Pseudomonas graminis, and one with Pseudomonas fluorescens. Phys...
متن کاملRed rot resistant transgenic sugarcane developed through expression of β-1,3-glucanase gene
Sugarcane (Saccharum spp.) is a commercially important crop, vulnerable to fungal disease red rot caused by Colletotrichum falcatum Went. The pathogen attacks sucrose accumulating parenchyma cells of cane stalk leading to severe losses in cane yield and sugar recovery. We report development of red rot resistant transgenic sugarcane through expression of β-1,3-glucanase gene from Trichoderma spp...
متن کاملDraft Genome Sequence of Colletotrichum falcatum - A Prelude on Screening of Red Rot Pathogen in Sugarcane
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 ...
متن کاملUse of simple sequence repeat markers for DNA fingerprinting and diversity analysis of sugarcane (Saccharum spp) cultivars resistant and susceptible to red rot.
Red rod is an economically important disease of sugarcane caused by the fungus Colletotrichum falcatum. We used a simple sequence repeat (SSR)-based marker system to identify and analyze genetic relationships of red rot resistant and susceptible sugarcane cultivars grown in Pakistan. Twenty-one highly polymorphic SSR markers were used for DNA fingerprinting and genetic diversity analysis o...
متن کاملThe Sugarcane Defense Protein SUGARWIN2 Causes Cell Death in Colletotrichum falcatum but Not in Non-Pathogenic Fungi
Plants respond to pathogens and insect attacks by inducing and accumulating a large set of defense-related proteins. Two homologues of a barley wound-inducible protein (BARWIN) have been characterized in sugarcane, SUGARWIN1 and SUGARWIN2 (sugarcane wound-inducible proteins). Induction of SUGARWINs occurs in response to Diatraea saccharalis damage but not to pathogen infection. In addition, the...
