  • Zn deficiency in Brassica napus induces Mo and Mn accumulation associated with chloroplast proteins variation without Zn remobilization
    Plant Physiology and Biochemistry, 2015
    Co-Authors: Vincent Billard, Maria Garnica, Florence Cruz, José-maria Garcia-mina, Anne Maillard, Alain Ourry, Jean Claude Yvin, Pascal Etienne
    Abstract:

    The importance of zinc (Zn) has been of little concern in human nutrition despite a strong decrease of this element in crops since the rise of high yielding Varieties. For better food quality, Zn biofortification can be used, but will be optimal only if mechanisms governing Zn management are better known. Using Zn deficiency, we are able to demonstrate that Zn is not remobilized in Brassica napus ( B. napus). Thus, remobilization processes should not be targeted by biofortification strategies. This study also complemented previous work by investigating leaf responses to Zn deficiency, especially from proteomic and ionomic points of view, showing for example, an increase in Manganese (Mn) content and of the Mn-dependent protein, Oxygen Evolving Enhancer.

  • biochemical selection of sorghum crop Varieties resistant to sorghum shoot fly atherigona soccata and stem borer chilo partellus role of allelochemicals
    1992
    Co-Authors: H Alborn, G Stenhagen, K Leuschner
    Abstract:

    The Semi Arid Tropics (SAT) is populated by more than 700 million people. Most of them are living on a subsistence level and are, for their food, dependent on the limited production of small farms. To be able to feed the increasing population of the SAT, new High-Yielding Varieties of traditional crops like sorghum have to be developed. Since most farmers have limited resources, and in order not to run into the same environmental difficulties experienced in the developed countries, insecticide use is mostly not feasible and should be kept at a low level. Host plant resistance is therefore essential for the stability of newly developed Varieties and hybrids. At ICRISAT (International Crops Research Institute for the Semi Arid Tropics, Patancheru, Andhra Pradesh, India) a broad germplasm base has been collected. For sorghum alone, 28000 germplasm accessions are available. The identification of resistance sources in the germplasm material by available methods is both intricate and time consuming.

  • multiple resistance to sorghum shoot fly spotted stemborer and sugarcane aphid in sorghum
    International Journal of Tropical Insect Science, 2006
    Co-Authors: H C Sharma, M K Dhillon, G Pampapathy
    Abstract:

    Sorghum is one of the most important cereal crops in the semi-arid tropics. Several insect pests damage it. The possibility of identifying genotypes with multiple resistance to these pests and transferring the relevant genes into High-Yielding Varieties and hybrids has been considered as an attractive approach to reducing yield losses. A set of 12 cytoplasmic male-sterile and maintainer lines, 12 restorer lines and their F1 hybrids were evaluated for resistance to sorghum shoot fly Atherigona soccata Rondani, spotted stemborer Chilo partellus (Swinhoe) and sugarcane aphid Melanaphis sacchari (Zehntner) under field conditions. There were significant differences among the genotypes tested. A total of 50% of male-sterile lines, 41.7% maintainers, 58.3% restorers and 35.4% of the hybrids tested showed moderate to high level of resistance to the three pests. The male- sterile and restorer lines showing resistance to different insects can be exploited for developing hybrids with multiple insect resistance for cultivation by the resource-poor farmers in the semi-arid tropics.
