Concluding Remarks
Boron is a crucial element for normal development and growth of plants. This
chapter highlights the positive effects of boron on crops and also describes the
interaction of B with the uptake of other nutrients. It further highlights the
importance of understanding the mechanisms of B action in plants and
determining the molecular mechanisms of plant responses to toxicity and
deficiency of B, to allow improvement of crops for tolerance to both condi-
tions. Deficient or toxic amounts of B may both have adverse effect on plants
and alter the uptake of other nutrients by direct or indirect interactions.
Increasing supply of B may result in increasing nutrient use efficiency
(NUE) and nutrient demand and supply (NDS). Alternatively higher levels
of B may exert antagonist effects on uptake of nutrients, negatively affecting
NUE and NDS. The mechanism underlying the B interaction with other
nutrients still remains unclear and requires further investigation. NUE is
studied typically for only one nutrient at a time and improving NUE for any
one nutrient almost certainly affects the NUE of other nutrients. However, the
interactions of B with other plant elements are complex and may exert
antagonistic or synergistic effects, which may be specific for species, growth
medium and different environments.
