Enhancement of developmental defects in the boron‐deficient maize mutant tassel‐less1 by reduced auxin levels

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Plant responses to deficiencies of the micronutrient boron are diverse and go beyond the well‐characterized function of boron in cell wall crosslinking. To explain these phenotypic discrepancies, hypotheses about interactions of boron with various phytohormones have been proposed, particularly auxin.
