Abstract:

Fifteen-day-old tomato and cotton hypocotyls were susceptible to degradation by the three fungi Aspergillus fumigatus, Fusarium oxysporum f.sp. lycopersici, and Fusarium oxysporum f.sp. vasinfectum. The last two fungi cause tomato and cotton wilts in Egypt. Addition of various concentrations (50–1200 ppm) of Goltix (4-amino-3-methyl-6-phenyl-1,2,4-triazine-5 (4H)-one(IUPAC)) inhibited the tomato cell wall degradation by the tested fungi except its pathogen, while the doses (50–1200 ppm) of Igran (4-ethylamino-2-tert-butylamino-6-methylthio-5-triazine) inhibited tomato cell wall degradation by the three fungi. On the other hand, the addition of various concentrations of Goltix to cotton cell wall culture increased the susceptibility of the cell wall to the degrading enzymes of the three fungi, while Igran inhibited the degradation by the two Fusarium species. The data also emphasized the presence of xylanase, arabanase, mannanase, galactanase, and cellulase enzymes in both tomato and cotton cell wall cultures of the tested fungi. Higher doses of either Goltix or Igran (800 and 1200 ppm) completely inhibited the activation of arabanase, xylanase, and mannanase, while cellulase and galactanase were less sensitive to the applied herbicide doses.

Abstract:

Commercial production of date palm fruit (Phoenix dactylifera L.) for fresh consumption has increased in the grove of Elx (Alacant Province, southeast Spain) after the successful development of tissue culture technologies and induced ripening and cold storage protocols. In a survey of losses after harvest, disease symptoms consisting of superficial, small, and firm black spots irregularly distributed throughout the fruit skin were observed in commercially handled and cold-stored fruit. At room temperature, superficial lesions expanded and produced dark mycelium. The potential causal agent was transferred to potato dextrose agar (PDA), incubated at 25°C in darkness, and subcultured on PDA. The identification was performed at the Spanish Type Culture Collection (CECT, University of Valencia, Spain) using colony morphology on PDA and malt extract agar at 26 or 37°C. At 26°C, the fungus rapidly produced cottony white mycelium that turned olivaceous and dark brown to black. Conidiophores were simple, straight or bent, with plain walls. Conidia were brown, obpyriform to ellipsoid (average 22 to 39 × 8 to 15 μm; n = 50), with both transversal and longitudinal septa, often observed in branched chains with more than 5 conidia. Growth occurred at 37°C. The identification of Alternaria alternata (Fr.:Fr.) Keissler was confirmed by the amplification and subsequent sequencing with the primers NL1 and NL4 of the region D1/D2 in the 5′ end of the 28S rRNA gene of the isolate IVIA DAA-4 (GenBank Accession No. JX987100). A BLAST search showed 100% identity with A. alternata strain DAOM 216376 (JN938894). Selected healthy ‘Medjool’ dates were surface disinfected by dipping them for 2 min in a 0.5% sodium hypochlorite solution and thoroughly rinsed with fresh water. To fulfill Koch's postulates, 20 μl of a spore suspension at 1 × 105 spores per ml prepared from 7-day-old colonies grown on PDA were placed in fresh skin wounds made in disinfected fruit using a sterile stainless steel rod with a probe tip 1 mm wide and 2 mm in length (one wound per fruit; three humid chambers with nine fruits each). Wounded but not inoculated fruit were used as controls (one humid chamber with nine fruit). While disease symptoms were observed on all fruit inoculated with A. alternata (average black spots of 3, 6, and 12 mm after 4, 7, and 10 days of incubation at 20°C), no decay was observed on any of the control fruit. Reisolation of the fungus was performed from 10 infected dates and it was positive in all cases. A. alternata has been reported to cause date palm fruit disease in Israel (1) and Egypt (2), whereas Alternaria spp. have been cited in California (3) and Iran (4). To our knowledge, this is the first report of A. alternata causing date palm fruit rot in Spain. References: (1) R. Barkai-Golan et al. Hassadeh 69:1446, 1989. (2) H. M. El-Deeb et al.

Abstract:

The cotton plant was recorded from Egypt in the Dynastic period as early as 2500 BC. Cotton seeds were recovered from Nubia (Egypt) in 1964. Many writers and relief sculptures as well as hieroglyphic symbols confirm cotton cultivation during this period. Cotton cultivation dominated in the Ptolemaic and Roman period (305 BC-AD 395). There were two cotton species (Gossypium arboreum L. and Gossypium herbaceum L.) grown in Egypt during the Islamic period (AD 1477-AD 1711). Later Ashmouni cotton was derived from Sea Island cotton (G. barbadense L. var. maritima Watt); Jumel's cotton (G. brasiliense Macf.) and other Egyptian stocks (possibly G. arboreum and/or G. herbaceum var. africanum (Watt) Hutchinson & Ghose). Ashmouni cotton was the main ancestor of Egyptian cultivare after 1887.

Abstract:

The cotton plant (Gossypium spp.) is sensitive to numerous environmental factors. This study was aimed at predicting effects of climatic factors grouped into convenient intervals (in days) on cotton flower and boll production compared with daily observations. Two uniformity field trials using the cotton (G. barbadense L.) cv. Giza 75 were conducted in 1992 and 1993 at the Agricultural Research Center, Giza, Egypt. Randomly chosen plants were used to record daily numbers of flowers and bolls during the reproductive stage (60 days). During this period, daily air temperature, temperature magnitude, evaporation, surface soil temperature, sunshine duration, humidity, and wind speed were recorded. Data, grouped into intervals of 2, 3, 4, 5, 6, and 10 d, were correlated with cotton production variables using regression analysis. Evaporation was found to be the most important climatic variable affecting flower and boll production, followed by humidity and sunshine duration. The least important variables were surface soil temperature at 0600 and minimum air temperature. The 5-d interval was found to provide the best correlation with yield parameters. Applying appropriate cultural practices that minimize the deleterious effects of evaporation and humidity could lead to an important improvement in cotton yield in Egypt.

Abstract:

SUMMARYTwo field experiments were conducted in Egypt in 1985 and 1986 to examine the responses of yield and its components and fibre quality in the Egyptian cotton cultivar Giza 75 to the spray application of 0, 10, 20, 40, 60, 80, and 100 mg of 1,1-dimethyl piperidinium chloride (Pix)/litre at 90 days or at 90 and 110 days after sowing. Number of opened bolls/plant, boll weight, seed and lint index, seed cotton yield/plant, seed cotton and lint yield/ha and yield earliness increased, but lint percentage decreased after Pix application. The number of opened bolls/plant increased after one application, but there was no effect from a further application. There were no effects of concentration or number of applications of Pix on any fibre property.

Abstract:

In the southwestern United States, rising costs and limited availability of water have lead to irrigation scheduling based on plant stress indicators in an effort to conserve water. This research was conducted to better define the recovery rates of transpiration, stomatal resistance, and leaf water potential in field grown extra long staple cotton (Gossypium barbadense cv. Pima S-6) following varied durations of water stress. Three water stress treatments were maintained by scheduling irrigations at different Crop Water Stress Index (CWSI) values. Plants irrigated at 0.19 and 0.68 CWSI units needed 72 hours for plant water potential to recover, while plants irrigated at 0.41 CWSI units needed only 24 hours. Water stress had a smaller effect on the recoveries of stomatal resistance and transpiration. Stomatal resistance recovered within 24 hours for all plants regardless of water treatment. Transpiration recovered within 24 hours for plants irrigated at 0.19 CWSI units, and within 48 hours for plants irrigated at 0.41 and 0.68 CWSI units.

Abstract:

Upland cotton (Gossypium hirsutum L.) is the world's most prominent fiber crop. Cotton transformation is labor intensive and time consuming, taking 12 to 18 months for rooted T0 plants. One rate limiting step is the necessary production of somatic embryos. In other recalcitrant species, ectopic expression of three genes were shown to promote somatic embryogenesis: WUSCHEL (WUS), SHOOT MERISTEMLESS (STM), and BABY BOOM (BBM). WUS is responsible for maintaining stem-cell fate in shoot and floral meristems. STM is needed to establish and maintain shoot meristems. STM and WUS have similar functions but work in different pathways; overexpression of both together converts somatic cells to meristematic and embryogenic fate. BBM encodes an AP2/ERF transcription factor that is expressed during embryogenesis and ectopic expression of BBM reprograms vegetative tissues to embryonic growth. In prior studies, these genes were constitutively expressed, and cultures did not progress beyond embryogenesis because the embryogenic signal was not turned off. In our study, we set out to use these genes to increase the efficiency of cotton transformation and decrease the time it takes to regenerate a plant. A disarmed cotton leaf crumple virus (dCLCrV) vector delivers WUS, STM, or BBM into cotton tissue cultures through Agrobacterium tumefaciens infection. We propose that virus delivery of embryo-inducing genes is a better approach for transformation because A) inserts more than 800 nucleotides are unstable, and will spontaneously inactivate, B) virus DNA can migrate through plasmodesmata to cells around the infected cell, creating a gradient of embryonic potential, C) the virus DNA does not pass through the germ line and the seed will not contain virus. We propose this method of inducing embryogenesis will facilitate the stable transformation of cotton and will be beneficial to the cotton industry. Ectopic expression of AtBBM, AtSTM, and AtWUS GrWUS:meGFP from a constitutive CaMV 35S promoter produced plants with phenotypes similar to those described in previous studies overexpressing AtBBM, indicating that the AtBBM gene was functional. The cotton cotyledon infiltration of the pART27 constructs showed transformed cells in Coker 312 by GFP localization in the nucleus. Although GFP was detected, no visible embryos appeared from the cotyledon. Cotyledons infiltrated with Agrobacterium harboring overexpression vectors withered and aborted after ~2 weeks. The virus-based vector in tissue culture failed to increase transformation efficiency, resulting in no embryos. The combination of hormone concentration showed no contribution to increasing the transformation efficiency.

Abstract:

Yaʿqūb Ṣarrūf’s first foray in the novel genre, Fatāt Miṣr (The Girl of Egypt) was serialized as a literary supplement to Al-Muqtaṭaf over the course of 1905. A tale of finance capital’s restless wandering in Egyptian cotton fields, Cairo apartment buildings, Japanese war bonds, and the stock markets of the world -- from London, to St. Petersburg, Tokyo and back to Cairo --, Fatāt Miṣr met with critical praise upon its initial publication. Soon forgotten, the novel has been left unread by Arabic literary critics, despite the prescient augury it held for how a culture of speculation in Arabic would culminate in Egypt less than two years later in the stock and real estate crash of 1907. Indeed, the plot of Fatāt Miṣr owes much to Ṣarrūf’s own personal financial speculation in Egyptian land.
