Variations in protein concentration and nitrogen sources in different positions of grain in wheat

The distribution patterns of total protein and protein components in different layers of wheat grain were investigated using the pearling technique, and the sources of different protein components and pearling fractions were identified using (15)N isotope tracing methods. It was found that N absorbed from jointing to anthesis (JA) and remobilized to the grain after anthesis was the principal source of grain N, especially in the outer layer. For albumin and globulin, the amount of N absorbed during different stages all showed a decreasing trend from the surface layer to the center part. Whereas, for globulin and glutenin, the N absorbed after anthesis accounted for the main part indicating that for storage protein, the utilization of N assimilated after anthesis is greater than that of the stored N assimilated before anthesis. It is concluded that manipulation of the N application rate during different growth stages could be an effective approach to modulate the distribution of protein fractions in pearled grains for specific end-uses

Examining feasibility, acceptability, and participant experiences of an anti-racist parenting intervention for White U.S. parents

Many White parents engage in minimal discussion of race and racism with their children, instead engaging in color-evasive practices that communicate that race is unimportant and that White people are racially neutral. Even White parents who express a commitment to anti-racist parenting frequently struggle to act on this commitment and feel underprepared to do so. The current mixed methods pilot study focused on the feasibility, acceptability, and participant experiences of an intervention ( CounterACT ) that aimed to address this gap in White U.S.-based parents\u27 skills and knowledge. Participants in the study were 27 White U.S.-based parents of 4- to 6-year-old White children who completed pre- and postintervention surveys as well as postintervention interviews. Findings suggest that the CounterACT model was feasible and acceptable. Parent self-report further suggests that CounterACT had beneficial effects on parenting, parents\u27 beliefs regarding White privilege, and children\u27s critical reflection. Parents reported positive experiences of CounterACT, particularly group components of the intervention. Key elements of participants\u27 experience included learning to understand their own and their children\u27s experience of Whiteness; learning to better tolerate and regulate emotional discomfort; connecting with others for motivation, accountability, and learning; and approaching racial socialization with greater intentionality. However, parents also experienced limits in their progress toward anti-racist parenting. Many indicated a desire for more concrete guidance and greater support enacting what they were learning in their own parenting. A particular concern was how to discuss White racial identities effectively. Our discussion highlights the implications of these findings for future work in this area.
