Systems genetics of environmental response in the mature wheat embryo.

Development of yellow rust resistant doubled haploid lines of wheat through wheat ´ maize Crosses

In order to produce doubled haploid lines of bread wheat resistant to strip or yellow rust, three F1 wheat hybrids were crossed using pollens of three maize hybrids. Out of 1071 pollinated florets, success in seed set ranged from 63.1% to 93.3% (mean 78%). Differences in seed set among the crosses were not significant. Embryo formation in the seeds developed on different crosses also varied fro...

Key Genes Involved in Wheat Response to Salinity Stress and Mapping their Gene Network

Extended Abstract Introduction and Objective: Considering the importance of salinity in wheat and the multigene nature of this trait, the present study was conducted to investigate the expression of key genes involved in the response of wheat to this stress and to create their network. Material and Methods: In this study, the expression of key genes (HKT, DREB, bZIP, NAC, and WARKY) involved...

Influence of environmental factors on the sap flux density of mango trees under rain-fed cropping systems in West Africa

Xylem sap flux density (Fd) was measured, on a 43-year-old (mature) and three 4-year-old (young) mango (Mangifera indica L.) trees, using Granier-type probes. The relative influences of environmental variables were examined under well-watered condition. Circumferential variation in Fd was also investigated by placing sensors on the north, south-west and south-east sides of the mature tree. Sap ...

Evaluation of Effect of β-Lactam Antibiotics on Suppression of Different Strains of Agrobacterium tumefaciens and on Wheat Mature Embryo Culture

Investigation of SSM-Wheat Model to Forecast of Growth and Yield of Wheat in Response to Fertilizer Nitrogen in order to Decrease Pollution Environmental and Diseases

Objective: Environmental and economic challenges resulting from the application of nitrogen fertilizers have increased Concerns about its productivity in the agricultural systems. Thus an experiment in order to investigate ability SSM-Wheat for simulation growth and yield of wheat (cultivar N-87-20) in response to fertilizer nitrogen in the direction decrease Pollution environm...
