Cultural Management of Huanglongbing: Current Status and Ongoing Research

Alquézar-García, Berta; Carmona, Lourdes; Bennici, Stefania; Miranda, Marcelo P.; Bassanezi, Renato B.; Peña, Leandro (Scientific Societies, 2022-01)

[EN] Huanglongbing (HLB), formerly known as greening, is a bacterial disease restricted to some Asian and African regions until two decades ago. Nowadays, associated bacteria and their vectors have spread to almost all ...
Curing and low-temperature combined post-harvest storage enhances anthocyanin biosynthesis in blood oranges

Carmona, Lourdes; Alquézar-García, Berta; Diretto, Gianfranco; Sevi, Filippo; Malara, Tatiane; Lafuente, M. Teresa; PEÑA GARCIA, LEANDRO (Elsevier, 2021-04-16)

[EN] Anthocyanins are pigments present in blood oranges which can be enriched by post-harvest cold storage. Additionally, citrus fruits contain appreciable levels of other flavonoids, whose content increases under postharvest ...
Engineered Orange Ectopically Expressing the Arabidopsis beta-Caryophyllene Synthase Is Not Attractive to Diaphorina citri, the Vector of the Bacterial Pathogen Associated to Huanglongbing

Alquézar-García, Berta; Linhares Volpe, Haroldo Xavier; Facchini Magnani, Rodrigo; Pedreira de Miranda, Marcelo; Almeida Santos, Mateus; Vieira Marques, Viviani; Rodrigues de Almeida, Márcia; Arno Wulff, Nelson; Ting, Hieng-Ming; de Vries, Michel; Schuurink, Robert; Bouwmeester, Harro; Peña, Leandro (Frontiers Media SA, 2021-03-02)

[EN] Huanglongbing (HLB) is a destructive disease, associated with psyllid-transmitted phloem-restricted pathogenic bacteria, which is seriously endangering citriculture worldwide. It affects all citrus species and cultivars ...
Generation of Transfer-DNA-Free Base-Edited Citrus Plants

Alquézar-García, Berta; Bennici, Stefania; Carmona, Lourdes; Gentile, Alessandra; Peña, Leandro (Frontiers Media SA, 2022-03-15)

[EN] To recover transgenic citrus plants in the most efficient manner, the use of selection marker genes is essential. In this work, it was shown that the mutated forms of the acetolactate synthase (ALS) gene in combination ...
Impact of D-limonene synthase up- or down-regulation on sweet orange fruit and juice odor perception

Rodríguez-Baixauli, Ana María; Peris-Rodrigo, Josep Enric; Redondo, Ana; Shimada, Takehiko; Costell, Elvira; Carbonell, Inmaculada; Rojas, Cristina; Peña, Leandro (Elsevier, 2017)

[EN] Citrus fruits are characterized by a complex mixture of volatiles making up their characteristic aromas, being the D-limonene the most abundant one. However, its role on citrus fruit and juice odor is controversial. ...
Improvement of Antioxidant Properties in Fruit from Two Blood and Blond Orange Cultivars by Postharvest Storage at Low Temperature

Carmona, Lourdes; Sulli, Maria; Diretto, Gianfranco; Alquézar-García, Berta; Alves, Mónica; Peña, Leandro (MDPI, 2022-03)

[EN] Numerous studies have revealed the remarkable health-promoting activities of citrus fruits, all of them related to the accumulation of bioactive compounds, including vitamins and phytonutrients. Anthocyanins are ...
