Breeding for flavor in fruits and vegetables is a dauting task. For several years, scientists have relied on consumer panels and instrumental analysis to make judgment calls on the flavor phenotype to select for during a breeding process. While these methods are often accurate and reliable, they are rigorous, costly, time-consuming, and difficult to scale […]
Albino plants lack chlorophyll, which means that they cannot photosynthesize. These kinds of plant are unique and can offer information as to the molecular mechanism of chlorophyll degradation and photosynthesis in plants. Here, Arisha et al. explored the differences in gene expression patterns of seedling leaf tissues from albino mutant sweetpotatoes (Ipomoea batatas) and their […]
Gene mapping and QTL identification for the improvement of important traits have not been fully explored in an autopolyploid species like sweetpotatoes (2n=6x=90) due to its genetic complexity. Most sweet potato QTL mapping efforts have relied on models used for diploid species, leading to low density maps with restrictions on the statistical power for QTL […]
PollenCounter is an open source, ImageJ based macro that splits RGB images of stained pollen grains into the primary channels. The program estimates pollen viability in plants through analyzing red (total number of pollen grains) and green (only viable pollen grains) images, after which the particles are counted. This macro has been used to assess […]
Plant hormones such as jasmonates (JAs) and salicylic acid (SA) are known for their role in regulating plant growth under both abiotic and biotic stresses. These hormones, which are synthesized within the plant, can modulate cellular processes in targeted cells locally and can be moved to other parts of the plant. Aside from plant hormones, […]
Ubiquitination is a process of adding ubiquitin (a small regulatory protein) to a substrate protein, leading to its degradation. A wide variety of cellular processes necessary for plant growth and development are regulated by ubiquitination. E3 ubiquitin ligases are the largest family of proteins involved in the ubiquitination process and act through transferring target proteins […]
Starfruit is a sweet and sour fruit that has a shape of a five-point star. It belongs to the Oxalidaceae family and is a fruit of Averrhoa carambola, a species of tree native to tropical Southeast Asia. The fruit is consumed in many parts of the world and is known for its many economic, medicinal […]
Heterosis is phenomenon that occurs when crossbred individuals show qualities (such as such as size, growth rate, fertility, and yield) that are superior to those of both parents. In maize, heterosis can be explained in terms of hybrid vigor, and this has been well studied using traditional breeding. However, testing multiple heterotic groups in different […]
