Familiar citrus fruits such as sweet orange, lemon, lime and grapefruit are hybrids of three species: Citrus reticulate (mandarin), C. medica (citron), and C. maxima (pummelo). Cultivated varieties are generally vegetatively propagated, with diversity arising from spontaneous or induced somatic mutations.…

A healthy human diet should include phytonutrients such as carotenoids. Several approaches including classical breeding and transgenic plant production have been used to increase carotenoid abundance in plant tissues; challenges to these approaches include feedback controls, cell toxicity due to abnormally…

To meet the Sustainable Development Goal 2, Zero hunger, degraded ecosystems should be brought under cultivation with quality seeds that have good germination and produce healthy seedling for vigorous plant population establishment. Seed technologies like seed coating with inoculants, germination promoters,…

Medicinal plants, which the majority of people use to some degree for their health needs, provide a platform for engaging students in scientific inquiry. Straus & Chudler present an overview of online teaching resources focused on medicinal plants and ethnobotany. The sites highlighted provide a…

They say that “chacun à son gout” (each has his own taste), but when it comes to tomatoes there is near universal agreement that they don’t taste as good as they used to: a fact that is borne out by gas chromatography-mass spectrometry and the panel of taste-testers employed by Tieman et al. in…

Jatropha curcas is a perennial woody plant with high seed oil content that has potential to be used in biofuel production.  However, there is limited knowledge about the biology of seed oil production in Jatropha spp.  Sun. et al., used a genetic approach to identify a J. curcas QTL that controls seed…

Sexual reproduction, with all that recombination and independent assortment, is an excellent way to generate genetic diversity and increase the likelihood that some progeny will survive. However, the seed industry strives to produce genetically uniform seeds. Although there are various ways to circumvent…
