Salt tolerance is an important agriculture character in Oryza sativa (rice). This paper proposed a framework of Support Vector Machine Recursive Feature Elimination (SVM-RFE) for analysing Oryza sativa microarray data from GEO. Through preliminary selection using t-test and iterative feature selection by SVM-RFE, we obtained 541 candidate genes. We analysed top 10 genes, which may play highly i...

A long awn is one of the distinct morphological features of wild rice species. This organ is thought to aid in seed dispersal and prevent predation by animals. Most cultivated varieties of Oryza sativa and Oryza glaberrima, however, have lost the ability to form long awns. The causal genetic factors responsible for the loss of awn in these two rice species remain largely unknown. Here, we evalu...

abstract lowland rice (oryza sativa l.) in south asia is under stress, as nitrogen removals by crops are higher than their replenishment through fertilizers. limited information is available on optimizing nitrogen dose in lowland rice to turn out higher yield. the present investigation aimed to optimize nitrogen fertilization and it’s response to the growth and yield of lowland rice. we evaluat...
