Nitrogen deficiency restricts gall development by altering metabolic and hormonal networks in Zizania latifolia

open access: yesFrontiers in Plant Science
Zizania latifolia is an important aquatic vegetable, and its edible gall is induced by the fungus Ustilago esculenta. Gall development is influenced by multiple factors. Nitrogen (N) is a central determinant of plant development and crop quality, yet how

The activation of iron deficiency responses of grapevine rootstocks is dependent to the availability of the nitrogen forms

open access: yesBMC Plant Biology
Background In viticulture, iron (Fe) chlorosis is a common abiotic stress that impairs plant development and leads to yield and quality losses. Under low availability of the metal, the applied N form (nitrate and ammonium) can play a role in promoting or
