 One of the things to consider when you think about a stress-toned variety is that in the environment where you're targeting, the stress is not uniform. It's not going to be in every field or in every village. And so generally, when you have a new variety, that variety will be multiplied and disseminated over a particular area. And so ideally, you would like to have a variety that would grow well in the different conditions in that area, because the farmers who are growing it may have, they may have stress or they may not have stress. So that variety should have good agronomic characteristics. It should have high yield. It should have good quality. And in addition, it should fit into the cropping pattern. So once you have those conditions met, then you have the potential for a very successful variety. So what we'd like to do is build the stress tolerance into these kinds of varieties, so that even in the more unfavorable areas within a particular region, the farmers can still grow them and get a reasonable yield. And so in some areas you may have submergence. In some areas you may have risk of water stress. And in some areas you may have both that occur at different times of the season or over different seasons. So we think it's going to be useful to combine these various stresses together, appropriate for each location. There are a few examples where we have been able to combine, to some extent, the different stress tolerances. One of the early varieties that we developed with submergence tolerance was released in the Philippines as PSB RC68. It has some degree of drought tolerance also. And then we've developed, I would call them more like prototypes of varieties or breeding lines that combine drought tolerance with submergence tolerance and also salt tolerance and submergence tolerance. And it's generally relatively easy to combine submergence tolerance with these stress tolerances because it's a single gene trait and most of the tolerance comes from the sub one gene. And so you just need to introduce the sub one gene into those varieties and then they will combine the tolerances. There's also some speculation that the sub one gene itself could have a benefit on drought tolerance. For example, there was a paper that just came out this year in Plant Cell which indicates that the sub one gene may have a beneficial effect on drought tolerance. So it's certainly possible to combine multiple stresses and that's really one of the focuses we have now. The focus we have is to not only combine the different stress tolerances but to combine stress tolerance with other important traits like disease resistance. We haven't found anything like sub one, you know, the same level as sub one in other stresses. We found the, we will find genes that have moderate stress. Genes or QTLs, quantitative trait loci that have moderate stress tolerance and by combining several of them you can get a fairly good degree of stress tolerance. So one of the programs now is to introduce these kinds of genes for drought tolerance into widely grown varieties. And you know instead of introducing one sub one gene you have two or three drought tolerance genes that you're introducing.
