Drought stress, caused by lack of precipitation or irrigation, is one of the most challenging
problems in crop production in the US and worldwide. Drought alone affects 45% of the …

Salinity stress is one of the primary threats to agricultural crops resulting in impaired crop
growth and development. Although cotton is considered as reasonably salt tolerant, it is …

Large-scale genomic surveys of crop germplasm are important for understanding the
genetic architecture of favorable traits. The genomic basis of geographic differentiation and …

Upland cotton (Gossypium hirsutum) is the most important natural fiber crop in the world.
The overall genetic diversity among cultivated species of cotton and the genetic changes …

Island populations are much more prone to extinction than mainland populations. The
reasons for this remain controversial. If inbreeding and loss of genetic variation are involved …

We present an overview of the taxonomy of Gossypium L.(the cotton genus) and its
evolutionary history. Gossypium contains more than 50 recognized species, including …

Publisher Summary This chapter discusses the gene flow and introgression from
domesticated plants into their wild relatives. Domesticated plants cannot be regarded as …

Island populations are more prone to extinction than mainland populations, with island
endemic species having higher extinction rates than nonendemic species. Inbreeding …

Polyploidy is a prominent process in plant evolution; yet few data address the question of
whether homeologous sequences evolve independently subsequent to polyploidization. We …

With the advent of genetic engineering, designer crops might interbreed with natural
populations. Could such romances lead to the evolution of superweeds, as some have …
