Cetyltrimethylammonium bromide (CTAB)–based methods are widely used to isolate DNA
from plant tissues, but the unique chemical composition of secondary metabolites among …

Adaptive radiation is an evolutionary process that has been promulgated in some clades as
an explanation for species richness and disparity in morphological forms across ecological …

Gypsum soils occur around the world, mainly in arid regions. These harsh environments
promote unusual flora with high degrees of endemism. Mexico has extensive gypsum …

PREMISE OF THE STUDY: Historical patterns and processes of plants with an American
amphitropical disjunct (AAD) distribution have long interested botanists and …

Premise The use of cetyltrimethylammonium bromide (CTAB) is an effective and
inexpensive method of extracting DNA from plants. The CTAB protocol is frequently modified …

• Premise of the Study: Dispersal is a major feature of plant evolution that has many
advantages but is not always favored. Wide dispersal, for example, leads to greater seed …

Loasaceae, a mostly American group, is one of the largest families of Cornales. In spite of
considerable progress over the last 20 years, the relationships of some clades remain …

Staminodes are infertile stamens that have evolved numerous times across angiosperms;
however, little is known about the evolutionary transitions of staminodes, especially among …

Understanding species level relationships is a central goal in systematic botany; however,
complexes of closely related and morphologically similar species often pose considerable …

Abstract Aim Aridification of western North America from the Miocene to the Recent has
spurred plant migrations, as species invaded and/or diversified into newly formed floristic …
