Sexually differential tolerance to water deficiency of -A female-biased alpine willow.

Salicaceae plants are dioecious woody plants. Previous studies have shown that male individuals are more tolerant to water deficiency than females for male-biased poplars. However, is a female-biased species in nature.

Metabolic and physiological analyses reveal that Populus cathayana males adopt an energy-saving strategy to cope with phosphorus deficiency.

Dioecious trees have evolved sex-specific adaptation strategies to cope with inorganic phosphorus (Pi) limitation. Yet, little is known about the effects of Pi limitation on plant metabolism, particularly in dioecious woody plants. To identify potential gender-specific metabolites appearing in response to Pi limitation in poplars, we studied the metabolic and ionomic responses in the roots and leaves of Populus cathayana Rehd males and females exposed to a 60-day period of Pi deficiency.

Sexually differential gene expressions in poplar roots in response to nitrogen deficiency.

Nitrogen (N) is a key nutrient impacting plant growth and physiological processes. However, the supply of N is often not sufficient to meet the requirements of trees in many terrestrial ecosystems. Because of differences in production costs, male and female plants have evolved different stress resistance strategies for N limitation.
