This is a status paper on a destructive rice disease –bacterial blight (BB), caused by Xanthomonas oryzae pv. oryzae (Xoo). We review the occurrence and spread of this disease, the taxonomy and classification of the pathogen and strategies for disease management. Studies on pathogen variation have revealed that breeding with single major genes for resistance, may be ineffective due to resistanc...
The Small Tailed Han sheep and Hu sheep are two prolific local sheep in China. In this study, the polymorphisms of BMPR-IB (Bone morphogenetic protein receptor IB), BMP-15 (Bone morphogenetic protein 15) and FSHR (follicle stimulating hormone receptor) were investigated to check whether they are associated with litter size in Small Tailed Han sheep and Hu sheep. Consequently, three polymorphism...
To cope with the problem of salinity- and weed-induced crop losses, a multi-stress tolerant trait is need of the hour but a combinatorial view of such traits is not yet explored. The overexpression of PDH45 (pea DNA helicase 45) and EPSPS (5-enoylpruvyl shikimate-3-phosphate synthase) genes have been reported to impart salinity and herbicide tolerance. Further, the understanding of mechanism an...
Aluminum (Al) toxicity in acid soils is a major limitation to the production of alfalfa (Medicago sativa subsp. sativa L.) in the USA. Developing Al-tolerant alfalfa cultivars is one approach to overcome this constraint. Accessions of wild diploid alfalfa (M. sativa subsp. coerulea) have been found to be a source of useful genes for Al tolerance. Previously, two genomic regions associated with ...
Transgenic crops producing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) are extensively cultivated worldwide. To counter rapidly increasing pest resistance to crops that produce single Bt toxins, transgenic plant 'pyramids' producing two or more Bt toxins that kill the same pest have been widely adopted. However, cross-resistance and antagonism between Bt toxins limit th...
In eukaryotes, eIF4E translation initiation factors are essential proteins encoded by a small multigene family. In plants, they are a major source of host plant resistance to potyviruses that require specific 4E factors to infect cells. Combining mutations in different eIF4E genes could be a way of broadening the spectrum of plant resistance to viruses. We attempted to combine null mutations af...
