Abstract
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. Besides significant decreases in phosphorus contents in both Pi-deficient roots and leaves, the calcium level decreased significantly and the sulfur content increased significantly in Pi-deficient male roots, while the zinc and ferrum contents increased significantly in Pi-deficient female roots. Inorganic P deficiency caused a smaller change in the abscisic acid content, but a significant increase in the jasmonic acid content was detected in both leaves and roots. Salicylic acid significantly decreased under Pi deficiency in male leaves and female roots. Changes were found in phospholipids and phosphorylated metabolites (e.g., fructose-6-phosphate, glycerol-3-phosphate, glucose-6-phosphate, phosphoric acid and inositol-1-phosphate) in roots and leaves. Both P. cathayana males and females relied on inorganic pyrophosphate-dependent but not on Pi-dependent glycolysis under Pi-deficient conditions. Sex-specific metabolites in leaves were primarily in the category of primary metabolites (e.g., amino acids), while in roots primarily in the category of secondary metabolites (e.g., organic acids) and sugars. The metabolome analysis revealed that sexually different pathways occurred mainly in amino acid metabolism, and the tissue-related differences were in the shikimate pathway and glycolysis. We observed changes in carbon flow, reduced root biomass and increased amino acid contents in P. cathayana males but not in females, which indicated that males have adopted an energy-saving strategy to adapt to Pi deficiency. Thus, this study provides new insights into sex-specific metabolic responses to Pi deficiency.

Abstract
Populus is an effective model for genetic studies in trees. The genus Populus includes dioecious species, and the differences exhibited in males and females have been intensively studied. This review focused on the distinctions between male and female poplar and aspen plants under stress conditions, such as drought, salinity, heavy metals, and nutrient deficiency on morphological, physiological, proteome, and gene expression levels. In most studies, males of Populus species were more adaptive to the majority of the stress conditions and showed less damage, better growth, and higher photosynthetic capacity and antioxidant activity than that of the females. However, in two recent studies, no differences in non-reproductive traits were revealed for male and female trees. This discrepancy of the results could be associated with experimental design: different species and genotypes, stress conditions, types of plant materials, sampling sizes. Knowledge of sex-specific differences is crucial for basic and applied research in Populus species.

Abstract
Winter flooding events are common in some rivers and streams due to dam constructions, and flooding and waterlogging inhibit the growth of trees in riparian zones. This study investigated sex-specific morphological, physiological and ultrastructural responses to various durations of winter flooding and spring waterlogging stresses, and post-flooding recovery characteristics in Populus deltoides. There were no significant differences in the morphological, ultrastructural and the majority of physiological traits in trees subjected to medium and severe winter flooding stresses, suggesting that males and females of P. deltoides were winter flooding tolerant, and insensitive to winter flooding duration. Males were more tolerant to winter flooding stress in terms of photosynthesis and chlorophyll fluorescence than females. Females displayed greater oxidative damage due to flooding stress than males. Males developed more efficient antioxidant enzymatic systems to control reactive oxygen species. Both sexes had similarly strong post-flooding recovery capabilities in terms of plant growth, and physiological and ultrastructural parameters. However, Males had better recovery capabilities in terms of pigment content. These results increase the understanding of poplars's adaptation to winter flooding stress. They also elucidate sex-specific differences in response to flooding stress during the dormant season, and during post-flooding recovery periods.

Abstract
With increasing altitude, solar UV-B radiation is enhanced. Based on the phenomenon of male-biased sex ratio of Populus cathayana Rehder in high altitude alpine area, we hypothesized that males have a faster and more sophisticated responsive mechanism to high UV-B radiation than that of females. Our previous studies have shown sexually different responses to high UV-B radiation were existed in P. cathayana at the morphological, physiological, and transcriptomic levels. However, the responses at the proteomic level remain unclear. In this study, an isobaric tag for relative and absolute quantification (iTRAQ)-based quantitative proteome analysis was performed in P. cathayana females and males. A total of 2,405 proteins were identified, with 331 proteins defined as differentially expressed proteins (DEPs). Among of these, 79 and 138 DEPs were decreased and 47 and 107 DEPs were increased under high solar UV-B radiation in females and males, respectively. A bioinformatics analysis categorized the common responsive proteins in the sexes as related to carbohydrate and energy metabolism, translation/transcription/post-transcriptional modification, photosynthesis, and redox reactions. The responsive proteins that showed differences in sex were mainly those involved in amino acid metabolism, stress response, and translation/transcription/post-transcriptional modification. This study provides proteomic profiles that poplars responding to solar UV-B radiation, and it also provides new insights into differentially sex-related responses to UV-B radiation.

Abstract
Hydroponically grown tobacco (Nicotiana tabacum L. cv. Samsun) roots exude proteases under non-stressed conditions. Ten different proteases could be distinguished by 2D-zymography of root exudate. The majority of the gelatinolytic activity was susceptible to serine protease inhibitors. One of the proteases could be assigned to an EST (SGN-P361478) by mass spectrometry of immune-purified root exudate. The sequence was completed by RACE-PCR and shows typical serine protease features of subtilase family S8A. Thermostability and SDS-insensitivity indicate a kinetically stable enzyme. Phylogenetic classification of this highly gelatinolytic subtilase showed SDD1 to be the closest relative in Arabidopsis thaliana (L. Heynh.). Even closer related protein sequences could be found in other distant plant genera indicating a high conservation of the subtilase. A 5-methyltetrahydropteroyltriglutamate-homocysteine methyltransferase-like protein and suberisation-associated anionic peroxidase-like protein were co-immune-purified and identified by mass spectrometry and may constitute potential interaction partners.

Proteomics 2015; 16:614-28.

Abstract
Male and female poplars (Populus cathayana Rehd.) respond differently to nitrogen (N) and phosphorus (P) deficiencies. In this study, an iTRAQ-based quantitative proteomic analysis was performed. N and P deficiencies caused 189 and 144 proteins to change in abundance in males and 244 and 464 in females, respectively. Compared to N- and P-deficient males, both N- and P-deficient females showed a wider range of changes in proteins that are involved in amino acid, carbohydrate and protein metabolism, and the sexual differences were significant. When comparing the effects of N- and P-deficiencies, N-deficient females expressed more changes in proteins that are involved in stress responses and gene expression regulation, while P-deficient females showed more changes in proteins that are involved in energy and lipid metabolism, stress responses and gene expression regulation. The quantitative RT-PCR analysis of stress-related proteins showed that males have a better expression correlation between mRNA and protein levels than do females. This study shows that P. cathayana females are more sensitive and have more rapid metabolic mechanisms when responding to N and P deficiencies than do males, and P deficiency has a wider range of effects on females than does N deficiency.
