简介：An efficient system for the production of a recombinant miraculin protein in transgenic citrus plant cells was developed. Miraculin is a taste-modifying protein that can transform a sour taste into a sweet taste. A miraculin gene containing a N-terminal signal peptide was introduced into navel orange (Citrus sinensis) callus cells by Agrobacterium-mediated transformation. Transgenic green color so...

简介：Citrus Black Spot (CBS) is a disease affecting sweet orange, lemons and mandarin varieties in Africa, Oceania and Americas. In Europe, CBS is a quarantine disease, limiting the import of fresh fruits from citrus-producing countries of those continents. CBS is caused by the fungus Phyllosticta citricarpa, which induces damages in fruit flavedo affecting their appearance and additionally causing pre...

简介：Orange fruit is an excellent natural dietary source of phytochemicals and nutrients (as vitamin C, carotenoids, flavonoids and folic acid, among others) contributing to its quality, nutritional value and health benefits. In recent years, considerable advances in the understanding of the molecular basis regulating carotenoid biosynthesis have been accomplished and biotechnological strategies to mod...

简介：Citrus trees have a long juvenile phase that delays their reproductive development by more than 6 years. This represents a major obstacle for citrus breeding. The key genes regulating floral transition have been studied extensively in species such Arabidopsis thaliana and poplar. In recent years, a growing number of genes related to flowering have been identified in crop species. With the aim of a...

简介：Citrus fruits, which exhibit extensive diversity of carotenoid patterns, can serve as a unique system to improve the understanding of carotenogenesis. Herein, we engineered embryogenic calli from four citrus genotypes as engineered cell models (ECMs) by overexpressing a bacterial phytoene synthase gene (CrtB). Ripe flavedos (the colored outer layer of citrus fruits) were offered as a comparative s...

简介：Most of the citrus trees grown in Brazil are extensively managed with no irrigation, leaving trees more vulnerable to extended dry season, which may reach 90 days without rain in some areas. Thus, utilization of rootstocks more tolerant to drought, such as ‘Rangpur’ lime (Citrus limonia), is widely employed, while other rootstocks are not. Our laboratory has produced ‘Carrizo’ and ‘Swingle’ ...

简介：Citrus tristeza virus (CTV), the causal agent of the most devastating viral disease of citrus, has evolved three silencing suppressor proteins acting at intra- (p23 and p20) and inter-cellular level (p20 and p25) to overcome host antiviral defense. RNA interference (RNAi), an approach based on using dsRNA to trigger RNA silencing, has been widely used for generating transgenic plant resistant agai...

简介：β-Carotene is one of the most efficient carotenoid singlet oxygen quenchers and may interfere in free radical oxidation, typical of many degenerative diseases. Besides its activity as protective agent against oxidative stress, βヽarotene also plays a nutritional role as precursor of vitamin A with twice the efficiency of any other pro-vitamin A carotenoid. Orange fruit is an excellent natural di...

简介：Volatile organic compounds, most of them being terpenes, are signals emitted by plants for communication with the environment. Orange fruit accumulates mainly terpenes in mature peel oil glands, D-limonene accounting for approximately 97% of terpene content. We have generated transgenic orange plants carrying a D-limonene synthase gene in antisense (AS) configuration. Transgenic expression caused ...

简介：Citrus scab, caused by ElsinoA << fawcettii (anamorph Sphaceloma fawcettii), is a common foliar fungal disease affecting many citrus cultivars, including grapefruit. No commercial grapefruit cultivar is resistant to scab, and the disease results in severely blemished fruit which reduces its marketability. Transgenic 'Duncan' grapefruit trees expressing the antimicrobial attE gene were produced via...
