To understand the machinery underlying a tomato cultivar harboring the Hero A gene against cyst nematode using microarrays, we first analyzed tomato gene expression in response to potato cyst nematode (PCN; Globodera rostochiensis) during the early incompatible and compatible interactions at 3 and 7 days post-inoculation (dpi). Transcript levels of the phenylalanine ammonia lyase (PAL) and Myb-...

The almond, Prunus dulcis Miller which belongs to Rosaceae family, is one of the most important commercial and oldest cultivated tree nut crops. Almonds are classified as a ‘nut’ in which the edible seed is the commercial product. Therefore, pollination and fertilization are necessary in almond. The characteristic of cultivated almond to express gametophytic self- incompatibility discourages se...

With the objective to identify previously unknown parental relationships among grapevine cultivars, 352 cultivars of Vitis vinifera L. were analyzed at 17 microsatellite loci. 29 were found to be duplicate genotypes of other cultivars. From the 323 unique genotypes, 89 possible pairs of parents were identified for 52 cultivars (i.e., each putative progeny cultivar shared at least one allele wit...

We used native polyacrylamide gel electrophoresis to identify polymorphism levels in α- and β-esterase loci from leaf tissues of Brazilian soybean cultivars for the analysis of population genetic diversity and structure, and to investigate relationships between conventional and genetically modified cultivars. The cultivars included lines developed by a soybean-grower cooperative (CD), by ...

Acytogenetic study was performed on 66 tetraploid cotton cultivars (Gossypium hirsutum L.) and their hybrids. The cultivars studied differed significantly in their chiasma frequency and distribution as well as chromosome pairing indicating their genetic differences. Adjacent and alternate quadrivalents were formed in most of the cultivars. A-A or D-D heterozygote translocations occurred in most...

A replicated field study was conducted from 1972 to 1980 involving soybeans grown in 2-, 3-, and 4-year rotations with maize in soil infested with Meloidogyne incognita. Monocultured soybeans were maintained as controls. Cropping regimes involved root-knot nematode susceptible and resistant soybean cultivars and soybeans treated and not treated with nematicides. Yields of susceptible cultivars ...

Reasons for the variable amylose content of endosperm starch from waxy cultivars of barley (Hordeum vulgare) were investigated. The mature grains of most such cultivars contain some amylose, although amounts are much lower than in wild-type cultivars. In these low-amylose cultivars, amylose synthesis starts relatively late in grain development. Starch granules in the outer cell layers of the en...

The ROMVOX Text-toaSpeech synthesis system developed by our team is the first one that allowed the synthesis of any unrestricted Romanian text with intonation facilities on 1BM-PC compatible computers. During the last years of research several version of text-to-speech systems were achieved, trying to enhance their facilities. Our paper describes the present stage of our experiments performed i...

We present a next-generation architecture that addresses problems of dependability, maintainability, and manageability of I/O devices and their software drivers on the PC platform. Our architecture resolves both hardware and software issues, exploiting emerging hardware features to improve device safety. Our high-performance implementation, based on the Xen virtual machine monitor, provides an ...

Soybean (Glycine max) producers in Ohio rarely use soybean cyst nematode (Heterodera glycines, SCN)-resistant cultivars because of concerns over limited yield potential and lack of resistance to Phytophthora sojae. A two-year study was initiated to determine grain yield and nematode population increase on soybean cyst nematode-resistant cultivars in maturity groups II and III in production fiel...
