The article discusses the concept of high-impact practices (HIPs) in education and the potential for expanding the list of recognized HIPs beyond the current 11 practices. The author argues that there are other educational experiences that can deliver similarly impactful learning experiences to students and that including additional experiences as HIPs would broaden access to impactful learning opportunities. The article also highlights the importance of equitable access to HIPs and suggests leveraging co-curricular and extracurricular activities as potential hubs for implementing additional HIPs. The author emphasizes the need for a coordinated and expansive approach to HIPs to attract more participants and improve outcomes for a diverse population of students. [Extracted from the article]

• Arabidopsis cngc2 plants are hypersensitive to external calcium and exhibit reduced plant size and fertility, especially when they are treated with elevated but physiologically relevant levels of calcium. This report focuses on the role of cyclic nucleotide-gated channel 2 (CNGC2) in plant fertility. • To determine the cause of the reduced fertility, we investigated the flower structure and growth potential of both male and female reproductive organs in cngc2 plants grown in high-calcium conditions. • cngc2 mutants had short stamens that may limit pollen deposition and pistils that were not conducive to pollen tube growth. • Our data indicate that sporophytic, but not gametophytic, defects are the main cause of the observed reduction in seed yield in cngc2 plants, and suggest that correct cyclic nucleotide and calcium signaling are important for cell elongation and pollen tube guidance.
