Abstract

Brown rust, caused by Puccinia melanocephala has become a serious problem for sugarcane production in China. Therefore, 50 new elite varieties bred by the Chinese Sugarcane System were screened for brown rust resistance and the presence of a major resistance gene, Bru1. Identification of field...

Abstract

The current study aims at the molecular characterization of Pistacia atlantica Desf. Subsp atlantica in Northwestern Algeria. The genome size estimation was performed for the first time for the species using flow cytometry on 97 samples. The flow cytometry analysis led to estimate a very small...

Abstract

To elucidate the mechanism of organic acid metabolism in rootstocks under alkali stress, rootstocks A15 and A17 (V. amurensis cv. Zuoshan1 × SO4), both with strong alkaline resistance, and a control rootstock 1103P (V. berlandieri × V. rupestris) were used as materials. Tissue culture plants were...

CAB ReviewFull Text

The prediction of complex or quantitative traits from single nucleotide polymorphism (SNP) genotypes has transformed livestock and plant breeding, and is also playing an increasingly important role in prediction of human disease. Genomic predictions are made using a prediction equation derived from...

CAB ReviewFull Text

Many secondary metabolites in plants are involved in a range of plant physiological processes including abiotic stress tolerance. Major polyamine (PA) compounds including putrescine (Put), spermidine (Spd) and spermine (Spm) have structural, functional and regulatory activities that allow them to...

AbstractFull Text

Aim: To investigate the relationship between bacteria, catalase (CAT) and the pea aphid, Acyrthosiphon pisum, and the role of catalase in the immune responses of the pea aphid. Methods: The bacterial load in the aphid was determined by in vitro culturing and colony counting after Micrococcus luteus...
