We’re taking time to get to know the members of the GSA’s Early Career Scientist Committees. Join us to learn more about our early career scientist advocates. Aishwarya Kothari Community and Membership Engagement Subcommittee Montana State University Research interest I am a fourth-year PhD student at Montana State University studying plant genetics. My interests are in…

Researchers identified dozens of quantitative trait loci controlling important traits in Cannabis sativa. In 2014, United States federal law changed to allow scientific research on Cannabis sativa in states with regulated hemp programs. This legal shift opened the door to research that had previously been slow and difficult due to regulatory hurdles and funding challenges. A new study published…

Tissue culture causes heritable methylation changes in plants. Tissue culture is a useful tool for plant scientists and horticulturalists in large part because it allows them to produce clones. Inconveniently, however, these clones are not always identical to the original, as one might expect them to be. In a report in GENETICS, Han et al.…

Crop properties improved by point mutation in microRNA binding domain of Q gene. Humans have been cultivating wheat for ten thousand years, transforming it from an unruly grass into a useful crop highly adapted to our needs. But even after millennia, there are still new avenues for improving this staple food. A new type of…

Recent evolution of simple germ–soma division in a green alga sheds light on the early stages of complex multicellular life. Among evolution’s greatest innovations are germ cells. These specialized reproductive cells—familiar to us as sperm and eggs in humans—set the stage for complex multicellular life because they free up all the other cells in the…

Shrub rich in potentially anticancer and antimalarial cardenolide compounds is sequenced in search of biosynthetic pathways. The giant milkweed Calotropis gigantea, a flowering shrub that can grow to 13 feet tall, produces a multitude of chemicals that have possible anticancer and antimalarial properties. A new Genome Report published in G3 describes the plant’s genome, providing…

Corn feeds millions of people, and its low cost makes it particularly important in developing countries. However, it can’t be relied on as the sole source of protein for either humans or livestock because—like most cereals—corn is low in certain essential amino acids. In the 1960s, a type of corn was discovered with boosted levels of…

When a noni fruit ripens, it stinks like old cheese—or even vomit. Familiar to many in the form of expensive juices sold as health supplements, this pungent fruit is engaged in a slow-motion arms race with would-be insect pests. Fruit flies are unable to feast on noni—scientific name Morinda citrifolia—because the fruit is dosed with…

There’s no such thing as an obese plant. But that doesn’t mean plants can’t teach us something about fat. In the September issue of GENETICS, Ducos et al. show that a protein that controls fat accumulation in humans has a similar function in Arabidopsis. They also find that the human and plant proteins may be…

Even though domestic plants usually appear radically different from their wild relatives, they are often still able to interbreed. For transgenic crops carrying traits like herbicide resistance, this flexibility could pose a problem if they were to pollinate weedy relatives nearby. In the July issue of GENETICS, Adamczyk-Chauvat et al. examine the extent to which…

Rice is one of the most important food crops on earth. Like many other plants, the genome of this critical global species is dominated by transposable elements—selfish genes that multiply themselves to the detriment of their host. In the June issue of G3, Zhang and Gao analyze the genomic long terminal repeat (LTR) retrotransposon content…
