Affecting cucurbit hormonal status by a ZYMV transient expression vector National Institute of Agronomic Research
Davidovich, V.; Leibman, D.; Gal-On, A.; Perl-Treves, R..
Squash and cucumber plants were infected with ZYMV strains engineered to over-express enzymes involved in ethylene and gibberellin biosynthesis. Presence of the inserted ACS gene within the viral RNA was transient and the insert was deleted after 20-40 days. Ethylene over-expressing plants produced very high ethylene levels and were severely stunted. Monoecious cucumbers produced earlier, consecutive female flowers. Gibberellin over-expression was deduced from the observed phenotypic change, plants were taller and flowered earlier.

Breeding of cucumber (Cucumis sativus) for resistance to multiple diseases and other traits National Institute of Agronomic Research
Kushnereva, V..
The most effective and straightforward way of plant protection is the production of cucumber hybrids with resistance to multiple diseases. Therefore, breeding of cucumber hybrids with a combination of defensive traits is a major objective. The accurate choice of parental lines is the first step towards development of successful hybrids. A variety of methods were used in order to speed up the process of inbred line development: a range of various planting times, planting in greenhouses and hot beds, screening of germplasm for disease resistances under artificial inoculation as well as natural field conditions, high selection pressure, backcrossing, multi-stage hybridization. As a result, we have developed cucumber lines and hybrids combining complex...

Cucumber breeding and genomics: Potential from research with Cucumis hystrix National Institute of Agronomic Research
Jin-Feng Chen; Long-Zheng Chen; Yong Zhuang; You-Gen Chen; Xiao-Hui Zhou.
Cucumis hystrix Chakr. (2n=2x=24) is a wild Cucumis species found in Yunnan (China) having cross compatibility with cultivated cucumber (C. sativus L., 2n=2x=14). Since the first interspecific hybridization successfully made in 1995 and development of the synthetic allotetraploid species (C. X hytivus Chen and Kirkbride, 2n=4x=38) in 2000, experiments with C. hystrix and the progenies derived from this interspecific cross were carried out for the potentials in cucumber genetics and cultivar improvements. Some important characters or traits found in C. hystrix were introduced, and the novel germplasm developed from this cross and some results from genetic and epigenetic studies were summarized for the first time in this review. Future objectives are...

Detection of cucumber parthenogenic haploid embryos by floating of immature seeds in liquid medium National Institute of Agronomic Research
Lotfi, M.; Salehi, S..
Only a small percentage of seeds arisen by irradiated pollen include haploid embryo. Inspecting the seeds one by one for rescuing the embryos is a tedious and time consuming work which decreases haploid production efficiency in this method for cucurbit plants. Cucumber seeds formed three weeks after pollination with irradiated pollen were floated in liquid medium for about 10 days before excision of the embryos. This innovative method allowed a better development of haploid embryos; they turned to green and germinate like normal seeds and could be identified easily without the need of inspecting the seeds one by one. This method permitted an easier detection and extraction of embryos in comparison with common approach, increased the number and the quality...

Development and characterization of Cucumis sativus-hystrix introgression lines exhibiting resistance to downy mildew National Institute of Agronomic Research
Zhou, X.-H.; Wan, H.-J.; Qian, C.-T.; Chen, J.-F..
Stable C. sativus-hystrix introgression lines with fourteen chromosomes, derived from the interspecific hybridization between a wild relative of cultivated cucumber C. hystrix (2n=2x=24, HH) and a Chinese cucumber 'Beijingjietou' (C. sativus L., 2n=2x=14, CC) were characterized using morphological, cytological, and SSR analysis. In morphology, those introgression lines were characterized to have small-sized leaf, short fruit, and multi-branching habit which were closer to the wild parent (C. hystrix), and to have a fertility as high as that of cultivated cucumber. Cytological observation showed that sister chromatids in at least one pair of somatic chromosomes were delayed obviously in separation at late metaphase. At diakinesis, 0.2 tetravalents, 0.05...

How does the first fruit inhibit younger fruit set in cucurbits? National Institute of Agronomic Research
Baniel, A.; Saraf-Levy, T.; Perl-Treves, R..
In this study we describe the inhibitory effect exerted by developing cucumber fruits on later-developing ovaries. Such pollinated ovaries do not set fruit but do not degenerate readily, remaining in a "stand-by" state that can be reversed when older fruits are removed. An increase in fruit set and decrease in inhibition was obtained by exogenous gibberellin and cytokinin treatment, and to a lesser extent by auxin. A decrease in transcript levels of genes expressed during fruit set was apparent in inhibited ovaries.

Possible involvement of CsTypA1 in reproductive organ development of cucumber (Cucumis sativus) National Institute of Agronomic Research
Barak, M.; Trebitsh, T..
Cucumber (Cucumis sativus) is a monoecious plant that is extensively studied with respect to floral sex determination. While the genetic background, hormonal and environmental factors are well characterized, the molecular mechanisms regulating unisexual flower development are not well understood. Initially a cucumber floral bud is bisexual and has the potential to develop into a male or female flower. Using differential cDNA-AFLP analysis between plant apices of monoecious (predominantly male) and gynoecious (female) cucumber plants, we isolated a cDNA that encodes a putative GTP binding protein tyrosine phosphorylated protein A (CsTypA1). TypA genes are widely distributed in plants and prokaryotes. Bacterial TypA proteins are involved in protein...

The FT/TFL1 gene family in cucumber National Institute of Agronomic Research
Sato, H.; Heang, D.; Sassa, H.; Koba, T..
In Arabidopsis thaliana, FT and TFL1 are known to affect phase transition from vegetative phase to reproductive phase. It is also known that these genes also affect some growth habits such as flowering time and compactness. Especially, TFL1 and its functional orthologs, CEN in snapdragon and SP in tomato, were demonstrated to regulate growth habit of indeterminate type or determinate type. Cucumber cultivars also have two types of growth habit. Most of them were indeterminate types, however, taking into account of the characteristics such as yield, early harvest, and robustness, determinate type might be ideal for cultivating. In the present study, we identified one FT and five TFL1 homologs in cucumber and elucidated their genomic organization,...

The origin and mode of function of the Female locus in cucumber National Institute of Agronomic Research
Shiber, A.; Gaur, R.K.; Rimon-Knopf, R.; Zelcer, A.; Trebitsh, T..
Gynoecy in cucumber is controlled by the Female (F) locus that can be modified by other sex determining genes, environmental conditions and plant hormones. As in most of the Cucurbitaceae, the gaseous plant hormone ethylene induces female flower development and thus simulates the activity of the F locus. Monoecious (ff) cucumbers posses a single CsACS1 gene, while gynoecious plants posses an additional female-specific copy, denoted CsACS1G that was mapped to the cucumber Female (F) locus. To study the origin and function of the F locus we compared their genomic structure and investigated their expression pattern and the effect of reducing CsACS1/G transcript level in gynoecious plants. The CsACS1G and CsACS1 genes are identical twin genes except for the...

Toxic metabolites from culture filtrate of Fusarium oxysporum and its effects on cucumber cells and plantlets Rev. Microbiol.
Melo,Itamar Soares de; Piccinin,Everaldo.
Resistance of cucumber plantlets to culture filtrate of Fusarium oxysporum is correlated with resistance of single cells from callus. Single cells and plantlets of two cultivars of cucumber were incubated with culture filtrates. Rapid cell death occurred, as assessed by the stain fluorescein diacetate. More cell death ocurred in the cells of the cultivar Aodai than in to cells of the cultivar Caipira, which presented high level of resistance. Maximum toxic activity of culture filtrates was attained after 21-25 days of growth of the fungus.

Transgenic resistance to RNA viruses in cucurbits is dependant on transgene construct and varies between viruses National Institute of Agronomic Research
Leibman, D.; Wolf, D.; Segev, O.; Raskin, A.; Gaur, R.; Saharan, V.; Zelcer, A.; Gal-On, A..
Cucurbit production worldwide is affected by modern agricultural technologies that require massive investments of capital and knowledge. Viral diseases of cucurbit crops result in heavy yield losses, and may even jeopardize the production of these crops. The classical crop breeding for disease resistance in cucurbits is severely hampered by the lack of natural sources of durable resistance to some of the most destructive viruses. The generation of viral resistance by means of genetic engineering was reported and widely implemented for several crops, including cucurbits. Our laboratories have been involved in the evaluation of several genetic constructs for the generation of transgenic resistance to different groups of RNA viruses known to severely affect...
