Water availability and high soil fertility make inland valley landscapes suitable for sustainable rice-based cropping. In this study, Random Forests statistical analysis was used on a database of 499 surveyed inland valleys in four study zones in three West African countries. The goal of the stud...

The application of silicon (Si) fertilizers reduces the severity of blast, caused by Magnaporthe grisea, in irrigated and upland rice; however, little research has been conducted to examine the epidemiological and etiological components of this reduction. Four cultivars of rice with differential ...

In this study forest fallows (locally known as ‘purmas’) are classified and described in three categories: natural fallow succession (PS), degrading fallow vegetation (PD) and fallow dominated by kudzu (Pueraria phaseoloides) (PK). The study area of Semuya has 83% under PS, and the area of Nueva ...

Two sets of experiments were conducted to compare the relative stability of partial and complete resistance in rice to Pyricularia grisea (causal agent of the rice blast disease) in a disease hot spot in eastern Colombia. In the first set of experiments, 186 breeding lines selected at the site ...

Increasing drought resistance without sacrificing grain yield remains an ongoing challenge in crop improvement. In this study, we report that Oryza sativa CCCH‐tandem zinc finger protein 5 (OsTZF5) can confer drought resistance and increase grain yield in transgenic rice plants. Expression of OsT...

Biotrophic invasive hyphae (IH) of the blast fungus Magnaporthe oryzae secrete effectors to alter host defenses and cellular processes as they successively invade living rice (Oryza sativa) cells. However, few blast effectors have been identified. Indeed, understanding fungal and rice genes contr...

This paper summarizes results from a decade of collaborative research using advanced backcross (AB) populations to a) identify quantitative trait loci (QTL) associated with improved performance in rice and to b) clone genes underlying key QTLs of interest. We demonstrate that AB-QTL analysis is c...
