Compared to the literature on the impact of post-secondary institutions on undergraduate institutions, the literature on the academic experiences of graduate students from underrepresented populations is comparatively meager.This book remedies this g

Transmission-blocking strategies that slow the spread of SARS-CoV-2 and protect against COVID-19 are needed. We have developed a shelf-stable, orally-delivered Ad5-vectored SARS-CoV-2 vaccine candidate that expresses the spike protein. Here we demons

Molecular knowledge of pathways regulating seed formation in legumes, remains scarce. Thirteen isolated cell-type transcriptomes were developed, spanning temporal events of male and female gametogenesis and seed initiation, to examine pathways involv

Apomixis results in asexual seed formation where progeny are identical to the maternal plant. In ovules of apomictic species of the Hieracium subgenus Pilosella, meiosis of the megaspore mother cell generates four megaspores. Aposporous initial (AI)

Background and Aims Apomixis, or asexual seed formation, in polyploid Hieracium subgenus Pilosella species results in clonal progeny with a maternal genotype. An aposporous embryo sac forms mitotically from a somatic cell, without prior meiosis, whil

Apomixis in Hieracium praealtum follows a developmental pathway of apospory, where an unreduced embryo sac develops from a somatic ovule cell without meiosis. The avoidance of meiosis together with fertilization-independent seed formation leads to cl

Key message Cowpea reproductive tools. Abstract Vigna unguiculata L. Walp. (cowpea) is recognized as a major legume food crop in Africa, but seed yields remain low in most varieties adapted to local conditions. The development of hybrid cowpea seed t
