“…We could also observe significant differences for number of conidial spores in susceptible hybrid CMS 850A x R-GM-69 as compared to highly susceptible check Morden. These microscopic observations are in line with Reddy et al, (2013) they also reported less conidial spores and hyphal growth in resistant and moderately resistant sunflower genotypes compared to susceptible check (Fig. 4).…”

“…Sunflower seed yield and oil quality is being severely affected by incidence of powdery mildew disease at early stages of crop growth (Reddy et al, 2013 chemical based protection measures are uneconomical specially in rainfed ecosystem. Plant resistance is the most common and efficient method of tackling the powdery mildew disease.…”

“…Screening of sunflower hybrids against powdery mildew in natural conditions: Twenty three hybrids were sown in RCBD design with three replications along with susceptible checks during late kharif 2014 and screening was carried out by leaf stapling method (Reddy et al, 2013). The powdery mildew disease incidence was recorded at 15 days interval from 30 DAS upto 90 DAS by randomly selecting five plants in each cross and post harvest observations were also recorded after harvesting.…”

“…Since decades, disease is being observed regularly during rabi-summer seasons and under severe conditions disease is found infecting whole plant starting from the cotyledonary leaves up to ray florets. The higher severity has been observed in tropical parts of the world, where it advances senescence of plant at the flowering or post flowering stages (Reddy et al, 2013). In India, powdery mildew disease on sunflower was first reported in Bombay (Patel et al, 1949) later in Rajasthan (Prasada et al, 1968) and West Bengal (Goswami and Dasgupta, 1981) causing a considerable reduction in yield.…”

Powdery mildew caused by Golovinomyces cichoracearum is the most important disease on sunflower worldwide. The investigation was undertaken to determine the mode of genetic inheritance of powdery mildew resistance in five F 1 and F 2 populations of sunflower. The four hybrids were derived by crossing resistant with susceptible genotype and one hybrid between resistant and highly susceptible genotype. Out of 23 hybrids, five crosses viz., PM-22x PM-36, PM-14xPM-36, PM-16xPM-38, PM-17xPM-35 and PM-34x PM-23 were resistant under natural as well as artificial epiphytotic screening conditions and the same five resistant hybrids segregated in 9R:7S ratio in F 2 population indicating involvement of two independent loci controlling powdery mildew resistance in sunflower.

“…Highest severity of powdery mildew is reported in the tropical countries . The powdery mildew pathogen in sunflower, Golovinomyces orontii is a biotrophic fungus that occurs on wild perennials, wild annuals, and cultivated sunflower . The disease appears during flowering and post‐flowering stages and hence, control strategies are not employed.…”

Powdery mildew (PM, caused by Golovinomyces orontii) is one of the major diseases on sunflower that causes severe yield losses in the tropics. Sources of resistance to PM are reported in an exotic accession and some wild Helianthus species. The present study aims at quantitative proteomic analysis of susceptible, resistant, and immune genotypes of sunflower in response to PM infection at 3, 7, 10 days post infection. The majority of differentially expressed proteins in the resistant genotype belonged to oxidative stress (catalase, ATP-sulfurylase, and formate dehydrogenase), defense (HSP-70, heat shock transcription factors), and photosynthesis (LHCB3). In case of immune genotype, 50% of proteins are related to photosynthesis, which play a key role in plant immunity, whereas a few similar proteins are also expressed in the susceptible genotype, but in their reduced abundance besides being inadequate in timing of expression probably leading to its susceptibility to PM. KEGG enrichment analysis shows that carbon metabolism (6-phosphogluconate dehydrogenase, pyruvate dehydrogenase, glutamine synthetase), photosynthesis, and plant-pathogen protein pathways are key pathways governing the resistance. The transcriptional expression of eight of nine differentially expressed proteins are in agreement with the expression of proteins at the corresponding time. The present study provides information on the key proteins that are upregulated in resistant and immune genotypes which restrict the disease progression and constitutes the first quantitative proteomic data of sunflower-PM infection process.
