Mango Malformation

Using two-phase solvent systems for sample pretreatment increases yield of counter-current chromatography: Anemarrhena asphodeloides saponins, a case study

“…In order to remove the influence of mangiferin, the solvent system of 1-butanol/water (1:1, v/v) containing 0.01 mol/L CuSO 4 in water was used. In this system, mangiferin produced a significantly smaller K value of 1.01 due to forming a complex with Cu 2+ [19], while the K values of compounds 1 and 2 were 1.38 and 1.59, respectively. Mangiferin can be easily removed as an impurity in this way.…”

Transcriptomic Analysis of Brassinosteroid Biosynthesis and Signaling Pathway Genes in Healthy and Malformed Tissues of Mango Variety Amrapalli

“…The etiology of malformation has been a contentious issue, and a wide range of biotic and abiotic factors have been reported to cause the disease, including viruses, mites and nutritional deficiencies (Ploetz et al, 2002;Nailwal et al, 2006;Jouyban, 2012). Convincing evidence on the involvement of a fungus as the causal agent of malformation has been in the literature for decades (Singh and Dhillon, 1990;Usha et al, 1997;Steenkamp et al, 2000;Ploetz et al, 2002, Nailwal et al, 2006Chakrabarti, 2011). However, based on Koch's postulate and detailed cytological examination of the infected tissues, it is now established that a fungus, Fusarium mangiferae induces the symptoms of mango malformation disease (Britz et al, 2002;Usha et al, 2009;Iqbal et al, 2010).…”

“…Several mango malformation disease management strategies such as use of different chemical pesticides, hormones, pruning diseased panicles etc. met with little or no success (Chakrabarti, 2011).…”

Mangiferin as a Biomarker for Mango Anthracnose Resistance

“…(Luo et al, 2012). This potent fungistatic compound is present in the leaves, stem bark, fruits, roots, and heartwood of mango trees (Chakrabarti, 2011;Rao et al, 2008;Singh et al, 2012). It is an important secondary metabolite that protects the plant against various biotic and abiotic stressors (Luo et al, 2012).…”

“…Lipooxygenases act on the CH-OH group of donors and act on single donors with the incorporation of molecular oxygen (Enzyme, 2011). It has been reported that the synthesis and accumulation of phenolic compounds impart disease resistance in plants (Chakrabarti, 2011). Xanthone is a heterocyclic compound with a boiling point of 350°C and a melting point of 174°C.…”
