The host-selective ACT toxin is essential for the pathogenesis of citrus fungal pathogen Alternaria alternata . However, mechanism ACT-toxin gene clusters biosynthesis regulated by still poorly understood. mainly multiple genes located in secondary metabolite cluster. In this study, we reported a transcription regulator ACTR contributes through mediating synthesis ACTS4 alternata. We generated ...

Throughout the history of citrus production in Florida one of the diseases with a major impact has been the Asian form of citrus greening (HLB), which was first detected in 2005. As a response to this introduction, new survey and detection methods had to be developed utilizing field observations directed not only to corroborate symptoms already reported in the literature, but to describe any va...

Genetic analysis of phenotypical traits and marker-trait association in polyploid species is generally considered as a challenge. In the present work, different approaches were combined taking advantage of the particular genetic structures of 2n gametes resulting from second division restitution (SDR) to map a genome region linked to Alternaria brown spot (ABS) resistance in triploid citrus pro...

OBJECTIVE To quantify five specific dietary phytosterols and phytostanols in vegetables and fruits commonly consumed in China. METHODS A total of 34 different kinds of vegetables and 33 kinds of fruits were chosen according to the consuming habit of Chinese people. All the samples were purchased from two shops in Beijing. The contents of phytosterols (beta-sitosterol, campesterol, stigmastero...

Citrus peels, waste by-products of citrus juices factories are reckoned valuable healthful functional food. Th is investigation evaluated antihyperglycaemic act ivity of citrus peels powders fortified biscuits in induced diabetic rats. 10% fortified b iscuits with peels powders of four studied citrus Groups, namely : Diabetic fed basal d iet (DFBD) + 10% fortified biscuits (FB) with Baladi oran...

The patient's diet has been considered an important etiological factor of dentin hypersensitivity. The frequent ingestion of acidic substances can promote the loss of dental structure or remove the smear layer. The purpose of this study was to evaluate the degree of smear layer removal and dentinal tubules exposure by different natural orange juices. Extracted human teeth were submitted to manu...

A novel Gram-stain-positive, motile, strictly aerobic bacterium, designated YIM 93174(T), was isolated from a salt field in Korea. Cells of this strain were rod-shaped and formed pale tangerine colonies and grew at pH 6.0-8.0 (optimal growth at pH 7.0), at 15-45 °C (optimum 28-37 °C) and at salinities of 0-10 % (w/v) NaCl (optimum 0-2 % NaCl). Some phenotypic characters allowed differentiation ...

Organic acids are essential to fruit flavor. The vacuolar H(+) transporting adenosine triphosphatase (V-ATPase) plays an important role in organic acid transport and accumulation. However, less is known of V-ATPase interacting proteins and their relationship with organic acid accumulation. The relationship between V-ATPase and citric acid was investigated, using the citrus tangerine varieties '...
