Genome‐Wide Association Study Reveals the Genetic Architecture and Key Drought and Yield Related Genes in Common Vetch (Vicia sativa L.)

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1082-1097, March 2026.
ABSTRACT Common vetch (Vicia sativa L.) is one of the most economically important annual pasture legumes worldwide. Many factors affect the yield of common vetch; however, the genetic architecture and gene functions associated with common vetch yield have not been explored. On the basis of 115.53 million single‐nucleotide polymorphisms (SNPs) and 18.55

Pollen morphology of the Megamexican cycads reveals the potential of morphometrics to identify cycad genera

Botan‪ical Sciences, 2020
Background: Although pollen morphology has always been an important tool in plant systematics, the possibility of distinguishing between related taxa is still debated. A difficult case is the cycads, where their morphology and small size is very similar.

Culture-based and Sanger sequencing approaches to uncover the diversity of leaf-fungal endophytes in neotropical gymnosperms

Tecnociencia
Endophytic fungi play a crucial role in the survival and adaptation of their host plants. In recent decades, unprecedented diversity of endophytic fungi has been reported in angiosperms, but knowledge about this diversity in tropical gymnosperms is ...
