“…Mango ( Mangifera indica L.) (2n = 40) is a member of the Anacardiaceae family, which was domesticated at least 4000 years ago in different regions of Asia [ 1 ]. Two ecogeographic races of mango have been distinguished: the Indian type, in subtropical regions, which produces monoembryonic seeds, and the Southeast Asian type, in tropical regions, which produces polyembryonic seeds [ 2 ].…”

Mango (Mangifera indica L.) (2n = 40) is a member of the Anacardiaceae family, which was domesticated at least 4000 years ago in Asia. Mangoes are delicious fruits with great nutritional value. They are one of the major fruit crops worldwide, cultivated in more than 100 countries, with a production of more than 40 million tons. Recently the genome sequences of several mango varieties have been released, but there are no bioinformatics platforms dedicated to mango genomics and breeding to host mango omics data. Here, we present MangoBase, a web portal dedicated to mango genomics, which provides multiple interactive bioinformatics tools, sequences, and annotations to analyze, visualize, and download omics data related to mango. Additionally, MangoBase includes a gene expression atlas with 12 datasets and 80 experiments representing some of the most significant mango RNA-seq experiments published to this date. These experiments study mango fruit ripening in several cultivars with different pulp firmness and sweetness or peel coloration, and other experiments also study hot water postharvest treatment, infection with C. gloeosporioides, and the main mango tree organ tissues.

Mango is the fifth most important fruit crop in the world in terms of production with an increasing demand for high-quality plant material for new plantings. Compared to other fruit tree crops, vegetative propagation in mango is slow and allows only a relatively limited production of plant material. To date, efficient procedures for in vitro establishment and micropropagation are not yet available in mango. This work aims at filling this gap. Germination of mango seeds in vitro, compared with ex vitro conditions, significantly increased the germination rate for the monoembryonic genotype tested (‘Irwin’). In vitro germination also increased the number of developed embryos for the two polyembryonic genotypes analysed, ‘Ataulfo’ and ‘Gomera-4’. Regarding the use of shoot tips for in vitro establishment and micropropagation, our results confirmed that this explant is not adequate for this purpose. We report for the first time the use of cotyledonary nodes as initial explants in mango. Axillary shoots were obtained in all the genotypes tested (‘Ataulfo’, ‘Sabre’, ‘Gomera-4’, ‘Irwin’ and ‘Keitt’), although the regeneration rate was highly genotype-dependent. Thidiazuron induced high-frequency regeneration patterns. The best results were observed with ‘Keitt’. When 3.0 mg l−1 thidiazuron was added to the medium, a 63.15% regeneration rate was reached and about 4 shoots per regenerating explant were obtained. Subsequently, microshoots excised from the cotyledonary nodes were successfully rooted in vitro and acclimatized to ex vitro conditions. Our results show that the use of cotyledonary nodes is efficient for mango mass propagation and, consequently, represents a qualitative advance for in vitro propagation of this recalcitrant species.
