Imagine you’re on a quest to deliver a package, racing against the competition. How do you prepare? Pollen grains and the pollen tubes that they form are essentially package-delivery systems. Their purpose is to deliver genetic information (sperm cell nuclei) to the ovule. Once the task is completed,…

Starch is the major storage carbohydrate in plants, and in Arabidopsis leaves it forms granules in the chloroplasts to supply energy during the night when photosynthesis is inactive. These semicrystalline granules are made of glucose chains, which can be mostly unbranched (amylose) or highly branched…

Cholesterol, an essential structural component of membranes and a precursor for steroid hormones, serves as a key metabolite at the interface of primary and secondary metabolism. However, the mechanisms regulating the balance between its diverse downstream metabolic pathways remain poorly understood.…

Although clusters of functionally related genes are common in prokaryotes, until recently it was thought that they were not a feature of eukaryotic genomes. However, several studies have identified biosynthetic gene clusters (BGCs) in plants. Many of these gene clusters include sets of enzymes that act…

Albert Einstein once said, “The only thing that you absolutely have to know is the location of the library.” Libraries house vast troves of information for readers to explore, analyze, and use. With the exponential increase in data, libraries have also evolved into digital databases and online platforms.…

Cassava (Manihot esculenta) is a vital starchy crop essential for food security in Sub-Saharan Africa, South America, and Southeast Asia. A recent study on cassava by Rüscher et al. provides important insights into the plant’s sugar control mechanisms as the roots expand, produce large amounts of…

Plant oils, composed of fatty acids, provide humans and animals with food, essential nutrients, chemicals, and biofuels. Plants accumulate over 450 “unusual” fatty acids, which could hold significant value if they achieve optimal production. Hydroxylated fatty acids (HFA) are unusual fatty acids…

The defensive alkaloid gramine, present in barley and other grass species, plays an important role in protecting the plant from insect damage but poses challenges for ruminant palatability. Breeding strategies balance these factors by maintaining the protective function and making the grain palatable…
