“…The higly virulent strain of F. mangiferae (MG06) isolated from an infected Keitt mango (Zhan et al, 2012 ) and preserved in the lab of SSCRI was used in this study. The pahtogen was inoculated into 1-year-old “Keitt” mango seedlings planted in 10 −L (plastic) pots in a glasshouse.…”

“…The fruit of mango ( Mangifera indica L.) is exceptional for its spicy, succulent, thick fruit pulp and abundant nutrients, containing a wide range of amino acids, sugar, organic acids, and minerals including Ca, P, Fe, and K as well as a great variety of vitamins. Mango cultivation is affected by specific constraints, among which mango malformation disease (MMD) caused by Fusarium mangiferae is considered to be one of the most important threats in the majority of mango-planting regions worldwide (Ploetz et al, 2002 ; Marasas et al, 2006 ; Zhan et al, 2010 , 2012 ). In the past decade, MMD has destroyed many thousands of hectares of mango in tropical and subtropical countries.…”

Malformation caused by Fusarium mangiferae is one of the most destructive mango diseases affecting the canopy and floral development, leading to dramatic reduction in fruit yield. To further understand the mechanism of interaction between mango and F. mangiferae, we monitored the transcriptome profiles of buds from susceptible mango plants, which were challenged with F. mangiferae. More than 99 million reads were deduced by RNA-sequencing and were assembled into 121,267 unigenes. Based on the sequence similarity searches, 61,706 unigenes were identified, of which 21,273 and 50,410 were assigned to gene ontology categories and clusters of orthologous groups, respectively, and 33,243 were mapped to 119 KEGG pathways. The differentially expressed genes of mango were detected, having 15,830, 26,061, and 20,146 DEGs respectively, after infection for 45, 75, and 120 days. The analysis of the comparative transcriptome suggests that basic defense mechanisms play important roles in disease resistance. The data also show the transcriptional responses of interactions between mango and the pathogen and more drastic changes in the host transcriptome in response to the pathogen. These results could be used to develop new methods to broaden the resistance of mango to malformation, including the over-expression of key mango genes.

Since the pathogen is easily disseminated in infected germplasm and there are conspicuous gaps in its geo graphic distribution, malformation may be even more widely spread (58).…”

New Insights into Mango Malformation Disease Epidemiology Lead to a New Integrated Management Strategy for Subtropical Environments

Mango (Mangifera indica) is regarded as the king of fruits in India, where it has been cultivated for at least 4,000 years and has great cultural and religious significance. Many Indian mango cultivars originated in the fifteenth century when the best selections of mango seedlings were propagated by grafting and planted in large orchards, in some cases numbering 100,000 trees. With the arrival of voyagers to India from Europe, mango was soon established throughout the tropics and subtropics. Mango malformation disease (MMD) is one of the most important and destructive diseases of this crop. It affects inflorescences and vegetative portions of the plant. Although trees are not killed, the vegetative phase of the disease impedes canopy development and the floral phase reduces fruit yield dramatically; substantial economic losses can occur since malformed inflorescences do not bear fruit. Significant advances have been made in understanding the etiology of MMD, which is caused by more than one agent. However, until recently little progress had been made on the epidemiology of this disease. The results that are discussed in this article are only for MMD caused by F. mangiferae.

“…Malformation caused by Fusarium species is an important and destructive plant disease which, to our knowledge, has been documented only on mango trees in most mango‐producing countries of Asia, Africa and America (Crespo et al, ). Several Fusarium species in the Gibberella fujikuroi species complex, including Fusarium mangiferae (Crespo et al, ; Gamliel‐Atinsky, Sztejnberg, Maymon, Shtienberg, & Freeman, ; Gamliel‐Atinsky, Sztejnberg, Maymon, Vintal, et al, ; Noriega‐Cantú et al, ; Sinniah et al, ; Zhan et al, ), F. proliferatum (Haggag & El‐Wahab, ; Mohamed Nor, Salleh, & Leslie, ; Zhan et al, ), F. sterilihyphosum (Britz et al, ; Steenkamp et al, ), F. mexicanum (Otero‐Colina et al, ), F. pseudocircinatum (Freeman et al, ) and F. tupiense (Crespo et al, ; Lamine, Sharma, Lava Kumar, & Bandyopadhyay, ), have been identified to be associated with vegetative and floral malformation disease of mango. Malformation affects both vegetative and reproductive tissues of the host plants.…”

Symptoms of vegetative malformation were observed on coconut palms (Cocos nucifera L.) in the Qeshm Island, Bandar Abbas and Minab, in Hormozgan province, southern Iran. The symptoms included misshapen and dwarfed leaves with shortened, thickened and tightened leaflets in wavy and zigzag form. The aim of this study was to identify the causal pathogen of coconut palm malformation and complete Koch's postulates for putative pathogen. Small pieces of surface‐disinfested malformed vegetative tissues of coconut palms were cultured on potato dextrose agar (PDA) medium. Fusarium isolates were permanently obtained from the symptomatic tissues. Sequence data from the internal transcribed spacer region (ITS1–5.8S‐ITS2) and translation elongation factor 1 alpha (TEF‐1α) gene were used for molecular identification of the isolates. BLAST search of the sequences showed 99%–100% identity to several Fusarium proliferatum strains in the GenBank, FUSARIUM‐ID and Fusarium MLST databases. A phylogeny inferred using individual sequence data from ITS region and TEF‐1α gene placed our isolates together with the other F. proliferatum sequences retrieved from the GenBank. Pathogenicity tests were carried out using one‐year‐old healthy coconut palm seedlings and conidial suspensions (106 conidia/ml) of the F. proliferatum isolates. The first visible symptoms appeared on newly produced leaves of the inoculated seedlings during the 16th week after inoculation, wherease no disease symptoms were observed on the control plants until the end of the experiment. Reisolation from symptomatic tissues of the inoculated seedlings yielded isolates of F. proliferatum with morphological and molecular characteristics identical to those of the isolates used for inoculations. This is the first report of coconut palm malformation caused by F. proliferatum worldwide.
