A new old species of Tetracera (Dilleniaceae) from Espinhaço Range, Brazil
Tetracera is the only genus within Dilleniaceae with a pantropical distribution. During efforts for a taxonomic revision of the neotropical species, we identified incongruences between application of names and their taxonomic identities, based on protologue and type specimen analysis. Here we describe a new species for the genus bearing a single carpel

Developmentally regulated genes drive phylogenomic splits in ovule evolution. [PDF]
: The evolution of seeds transformed life on earth and is responsible for our most important food crops. Gymnosperms, the oldest living seed plants, are an untapped genomic reservoir for genes involved in seed evolution. To tap this resource, we assemble

Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Assessing the Genotypic Differences for Seed Set and Seed Abortion in Tomato Genotypes [PDF]
Tomato (_Lycopersicon esculentum_ Mill.) is one of the most popular fruit vegetable around the world. Seed abortion where in only a small proportion of ovules in an ovary develops into matured seeds, is a wide spread phenomenon in multi-ovulated species.
