Macronutrient Distribution and Protein Secondary Structure of Cool-Season Oats Revealed by Synchrotron-Based Mid-IR Spectroscopy and FTIR Chemical Imaging: Effects of Variety and Steam-Pressure Toasting Duration

Ganqi Deng, María E. Rodríguez‐Espinosa, Kaiyang Tu, Jarvis A. Stobbs, Miranda Vu, Chithra Karunakaran, Xin Feng, Fang‐Xiang Wu, Peiqiang Yu

This study uses FTIR imaging and spectroscopy to analyze protein secondary structures and macronutrient distribution in oats, showing that toasting significantly alters protein structure while variety effects are minor.

Resolving the Foliar Calcium Mobility Paradox: Enhancing Foliar Calcium Transport in Tomato Using Osmotic Regulators

Eduardo Santos, Gabriel Sgarbiero Montanha, Higor José Freita Alves da Silva, Nicolas Gustavo da Cruz da Silva, Felipe Sousa Franco, Júlia Rossatto Brandão, Karina Angela Chimbo Huatatoca, Alex Virgílio, Chithra Karunakaran, Karen K. Tanino, José Lavres, Hudson Wallace Pereira de Carvalho

This study shows that foliar application of calcium with sucrose improves its transport to tomato fruits and seeds, challenging the assumption of limited foliar calcium mobility.
