“…En campo, el hongo produce infecciones quiescentes en frutos inmaduros, las cuales se desarrollan durante la poscosecha a causa del ambiente y maduración del fruto, provocando pérdidas que pueden superar el 50% (Arauz, 2000;Prusky et al, 2013;Kamle y Kumar, 2016). Su control se realiza principalmente con fungicidas sistémicos; aunque son eficientes, presentan efectos negativos como la residualidad o la generación resistencia en el hongo, siendo su uso cada vez menos aceptados por los países importadores, ya que su toxicidad es potencialmente nociva para el consumidor (Bautista-Rosales et al, 2014;Chechi et al, 2019).…”

“…In the field, the fungus produces quiescent infections in immature fruits, which develop during postharvest, due to the environment and the maturation of the fruit, causing losses that can exceed to 50% (Arauz, 2000;Prusky et al, 2013;Kamle and Kumar, 2016). It is mainly controlled using systemic fungicides which, although efficient, have negative effects such as residuality or the generation of resistance of the fungus, and its use is therefore becoming less accepted by importing countries, since its toxicity is potentially harmful to consumers (Bautista-Rosales et al, 2014;Chechi et al, 2019).…”

Se determinó la eficacia en el control de la antracnosis en la poscosecha de mango cv. Azúcar sometiendo la fruta a un tratamiento hidrotérmico a 53 °C, realizando posteriormente dos heridas de 2 mm de profundidad, luego se realizó la inmersión en suspensiones de los antagonistas o quitina en diferentes concentraciones, posteriormente en cada herida se inoculó una gota de 5 ?L del patógeno, almacenando la fruta a 23 °C. De este ensayo se seleccionó a <em>Lysinibacillus xylaniticus</em> Ap282, <em>Rhodotorula glutinis</em> Lv316 y quitina (10 mg L-1) por presentar una eficacia del 49% al 69% en el control de la enfermedad. El bioensayo se repitió, adicionando la quitina al tratamiento hidrotérmico y evaluando el control de la enfermedad a partir de infecciones quiescentes del patógeno, almacenando la fruta a 13 °C. La combinación del tratamiento hidrotérmico y el temperado de la fruta en la suspensión de AP282 presentó la mayor eficacia en el control de la antracnosis (84%) en frutos inoculados con el patógeno, mientras que, en el control de la enfermedad a partir de las infecciones quiescentes la combinación del tratamiento hidrotérmico adicionando la quitina o el temperado en suspensiones microbianas presentó una eficacia del 83 al 89%.

“…Some physical technologies, such as postharvest heat treatment and UV-C treatment, have been found to effectively control the postharvest diseases of fruits [ 3 ]. Synthetic fungicides including mancozeb, carbendazim, promethanide, and tecto60 have been confirmed to have obvious effects on inhibiting anthracnose in mango fruit [ 4 ]. Although these fungicides are effective for controlling pathogens, they do have negative influences on human health and the environment [ 5 ].…”

Postharvest anthracnose, caused by the fungus Colletotrichum gloeosporioides, is one of the most important postharvest diseases of mangoes worldwide. Bacillus siamensis (B. siamensis), as a biocontrol bacteria, has significant effects on inhibiting disease and improving the quality of fruits and vegetables. In this study, pre-storage application of B. siamensis significantly induced disease resistance and decreased disease index (DI) of stored mango fruit. To investigate the induction mechanisms of B. siamensis, comparative transcriptome analysis of mango fruit samples during the storage were established. In total, 234,808 unique transcripts were assembled and 56,704 differentially expressed genes (DEGs) were identified by comparative transcriptome analysis. Gene ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of DEGs showed that most of the DEGs involved in plant-pathogen interaction, plant hormone signal transduction, and biosynthesis of resistant substances were enriched. Fourteen DEGs related to disease-resistance were validated by qRT-PCR, which well corresponded to the FPKM value obtained from the transcriptome data. These results indicate that B. siamensis treatment may act to induce disease resistance of mango fruit by affecting multiple pathways. These findings not only reveal the transcriptional regulatory mechanisms that govern postharvest disease, but also develop a biological strategy to maintain quality of post-harvest mango fruit.

“…Chemical treatments are effectively used to withhold fungal diseases (Gur et al 2017(Gur et al , 2020Pagès et al 2020), but aforesaid treatments have negative side effects, for instance, environment unfriendly and food safety reduced (Hu et al 2017). The most remarkable scenarios for conquering fungal diseases in apple are to select fungal resistant apple sources and cultivating fungal resistant variations through breeding (Chechi et al 2019). As a result, it is very imperative to delve into the molecular mechanism potential fungal disease resistance in apple.…”

Apple (Malus domestica) is a delicious fruit and have high economic value. However, numerous destructive fungi affect apple tree and limit the development of apple production. Many researches showed that salicylic acid and jasmonic acid improved plant resistance to fungal disease, but the potential mechanisms between cytokinin and fungal disease were hardly reported. The IPT gene family encodes the proteins of synthetizing cytokinin and plays an indispensable role in plant biological stress. In our previous study, we found the disease resistance in autotetraploid apple was much better than ‘Hanfu’ and we analyze the gene expression in ‘Hanfu’ and autotetraploid apple. We found the MdIPT8 gene was significantly different expressed. Therefore, we focused on MdIPT genes. We uncovered ten IPT genes in the ‘Hanfu’ whole genome, that are unevenly distributed across five chromosomes. Phylogenetic analysis indicated this family falling into two groups. Moreover, the transcriptional analysis of ten IPT genes indicated MdIPT8 can be induced under Colletotrichum gloeosporioides stress stimulating in apple leaves. The MdIPT8 protein coalesced to green fluorescent protein pinpointed to the chloroplast. Finally, we confirmed that the overexpression of MdIPT8 increased resistance to C. gloeosporioides. Additionally, the endogenous cytokinin content of ‘Hanfu’ leaves increased under the stress of C. gloeosporioides and exogenous cytokinin improved the disease resistance of leaves. Our findings supply an overview of the identification of apple IPT gene family and increases the understanding of cytokinin in apple anthracnose resistance study.
