Huanglongbing (HLB), an insect-transmitted disease of citrus, known for many years in Asia and Africa, has appeared in the state of São Paulo State (SSP), Brazil, in 2004, and the state of Florida, USA, in 2005. HLB endangers the very existence of citrus, as trees infected with the bacterial pathogen, irrevocably decline. In the absence of curative procedures, control of HLB is difficult and on...

Phytochemical examination of Citrus sinensis flavedo var. Pineapple resulted in the isolation of six compounds characterized as tetracosane, ethyl pentacosanoate, tetratriacontanoic acid, tangertin, beta-sitosteryl-beta-D-glucoside and 3,5,4'-trihydroxy-7,3'-dimethoxy flavanone 3-O-beta-glucoside. Of these 3,5,4'-trihydroxy-7,3'-dimethoxy flavanone 3-O-beta-glucoside is a hitherto unreported co...

Mildew resistance Locus O (MLO), a gene family specific to plants, plays significant roles in the resistance to powdery mildew (PM) and response to a variety of abiotic stresses, plant growth and development. Despite their importance as barley, rice, wheat, few studies are reported in dicots except Arabidopsis; no global analysis has been performed in the burgeoning model fruit plant sweet oran...

Turunçgiller ülkemiz için hem üretim ve de ihracat bakımından en önemli meyve gruplarından biridir. içerisinde limonlar miktarı ilk sırada gelen türdür. Ülkemiz limon ihracatında İnterdonato, Lamas, Kütdiken Meyer çeşitleri yer tutmaktadır. Limonların kalite parametreleri ekolojiye göre farklılık göstermekle birlikte kullanılan anaç çeşitlerinin etkisi büyüktür. Ülkemizde yetiştiriciliğinde gen...

Herein, we report a draft genome sequence of the endophytic Curtobacterium sp. strain ER1/6, isolated from a surface-sterilized Citrus sinensis branch, and it presented the capability to control phytopathogens. Functional annotation of the ~3.4-Mb genome revealed 3,100 protein-coding genes, with many products related to known ecological and biotechnological aspects of this bacterium.

The aim of this study was to evaluate the membrane integrity and some physiological responses rootstock citrus calli under exposure different concentrations NaCl. Selected salt-tolerant cell lines were compared with salt-sensitive Troyer’s citrange (Citrus sinensis [L.] x Citrus trifoliata Raf.) (TC) respect growth, water content, Na+, K+ Cl? ion content as well stability NaCl concentrations. r...

La investigación se llevó a cabo en un huerto citrícola de naranja Citrus sinensis L. Var temprana Marrs. Utilizando diseño bloques completos al azar con cuatro tratamientos y repeticiones, análisis estadístico Tukey 0.5 %, comparación medias. Los fueron (T1) el complejo hormonal Biozyme TF utilizando 25 ml como recomendación del producto 20 L agua, (T2) utilizó fertilizante zinc (25 ml) (T3) g...

Bean thrips (BT), Caliothrips fasciatus (Pergande), is a pest of concern to certain countries that import fresh citrus fruit from California, USA. A series laboratory-scale exploratory fumigations with phosphine at 4.9 ± 0.3 °C (mean 2 SD; x¯±2s) were conducted evaluate the postharvest control adult BT. Models duration–mortality response predicted ca. 99% mortality BT populations when headspace...

Daily variations in net gas exchange, chlorophyll a fluorescence and water relations of mature, sun-acclimated grapefruit (Citrus paradisi Macfady.) and orange (Citrus sinensis L. Osbeck) leaves were determined in tree canopies either shaded with 50% shade screens or left unshaded (sunlit). Mean daily maximum photosynthetic photon flux density (PPFD) under shade varied from 500 to 700 micromol ...
