Abstract:
A total of 768 molecular markers were developed for Ipomoea batatas (L.) Lam., consisting of 689 simple sequence repeats (SSRs) and 79 single nucleotide polymorphisms (SNPs). All the markers were distributed across the sweet potato genome, averaging 51 markers per chromosome. The markers were tested on DNA samples from five cultivars of I. batatas, assessing their amplification efficiency and polymorphism. Here we provide the primer sequences tested, their chromosome locations, the analysis including amplicon sizes, and highlight 92 that showed polymorphism between Beauregard and Tanzania. This dataset offers valuable resources for constructing high-resolution linkage maps and facilitates advanced genetic studies and breeding programs in sweetpotato.

The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
02:27Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...
