Pearl millet is an important component of food security in the semi-arid tropics and is assuming greater importance in the context of changing climate and increasing demand for highly nutritious food and feed. Molecular tools have been developed and applied for pearl millet on a limited scale. However, the existing tool kit needs to be strengthened further for its routine use in applied breeding programs. Here, we report enrichment of the pearl millet molecular linkage map by exploiting low-cost and high-
Studies in A. thaliana reported a genomic region responsible for drought avoidance co-130 mapping with a region contributing to a constitutively lowered Tr and simultaneously 131 leading to an enhanced TE (Masle et al. 2005;McKay et al. 2008). Following these 132 examples, our current hypothesis is that only critical portions of the large DT-QTL, 133 linked to specific mechanisms, matter for the terminal drought tolerance of pearl millet 134 and these needs to be accurately mapped to enhance the precision of marker assisted 135 introgression. In addition, Tr is only one component of plant water use, which likely 136
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
