“…The down-regulation of starch and sucrose caused nutrients deficiency and disordered energy metabolism, which could lead to stamen abortion in Solanum lycopersicum and Brassica campestris Yang et al, 2021). Similarly, the male trees of Populus cathayana had a higher capacity of carbon fixation and carbon sequestration (Wu et al, 2021). Furthermore, the SWEET transporter genes were significantly up-regulated during floral differentiation process, and could be capable to complement yeast cell uptake on sugar substrates (Wang P. et al 2019).…”

Zanthoxylum armatum is a prominent plant for food industries. Its male flowers often occur in gynogenesis plants; however, the potential mechanism remains poorly understood. Herein, a total of 26 floral sex differentiation stages were observed to select four vital phases to reveal key factors by using RNA-seq, phytohormones and carbohydrates investigation. The results showed that a selective abortion of stamen or pistil primordia could result in the floral sex differentiation in Z. armatum. Carbohydrates might collaborate with cytokinin to effect the male floral differentiation, whereas female floral differentiation was involved in SA, GA1, and ABA biosynthesis and signal transduction pathways. Meanwhile, these endogenous regulators associated with reproductive growth might be integrated into ABCDE model to regulate the floral organ differentiation in Z. armatum. Furthermore, the 21 crucial candidates were identified in co-expression network, which would contribute to uncovering their roles in floral sex differentiation of Z. armatum in further studies. To the best of our knowledge, this study was the first comprehensive investigation to link floral sex differentiation with multi-level endogenous regulatory factors in Z. armatum. It also provided new insights to explore the regulatory mechanism of floral sex differentiation, which would be benefited to cultivate high-yield varieties in Z. armatum.

“…A previous proteomic analysis revealed sexual differences in the metabolic process of poplar trees under nitrogen deficiency [ 17 ]. Further study showed that male Populus trees had stronger capacity for carbon fixation and higher content of leaf abscisic acid and carbon sink than females under nitrogen deficiency [ 18 ]. In Ginkgo biloba , genomic analysis examined sex-related metabolic variations, such as specialized flavonoid metabolism and regulation [ 19 ].…”

Taxus trees are major natural sources for the extraction of taxol, a worldwide used anti-cancer agent. Taxus media is a dioecious woody tree with high taxol yield. However, the sexually dimorphic accumulation of taxoids in T. media is largely unknown. Our study revealed high accumulation of taxoids in the female T. media trees using a UPLC-MS/MS method. Thereafter, many differential metabolites and genes between female and male T. media trees were identified using metabolomic and transcriptomic analyses, respectively. Most of the taxol-related genes predominantly expressed in the female trees. A female-specific R2R3-MYB transcription factor, TmMYB39, was identified. Furthermore, BiFC and Y2H assays suggested the potential interaction between TmMYB39 and TmbHLH13. Several taxol biosynthesis-related promoter sequences were isolated and used for the screening of MYB recognition elements. EMSA analysis indicated that TmMYB39 could bind to the promoters of the GGPPS, T10OH, T13OH, and TBT genes. Interaction between TmMYB39 and TmbHLH13 trans-activated the expression of the GGPPS and T10OH genes. TmMYB39 might function in the transcriptional regulation of taxol biosynthesis through a “MYB-bHLH” module. Our results gave a potential explanation for the sexually dimorphic biosynthesis of taxol in T. media.

“…Moreover, they are particularly vulnerable to the effects of climate and environmental changes [ 26 , 27 ]. Most prior research analysed the impacts of environmental changes concerning dioecious plant growth, biomass allocation, and seedling survival, but the long-term impact on the reproductive success of plants has rarely been studied [ 28 , 29 , 30 , 31 , 32 ]. Thus, for many woody species, there is still a lack of a molecular sex marker, and the plant sex can be described only by reproductive structures generated on the shoots [ 33 , 34 ].…”

Although seed quality and quantity, as well as reproductive performance are important life history stages of plants, little is known about the reproductive responses of trees to environmental changes such as increased anthropogenic deposition of nitrogen (N) and phosphorus (P). Dioecious plants are good models with which to test the environmental impact on female or male reproductive responses individually. We analysed effects of different long-term nutritional availability on the reproductive performance of two dioecious species (Taxus baccata L. and Juniperus communis L.) characterised by different life histories. By using pot experiments with vegetatively propagated plants grown in different fertilisation conditions, we observed an increase in plant growth and strobili production but a decrease in seed efficiency. Seeds produced by fertilised plants had greater seed mass. Fertiliser addition did not change C or N content nor the C/N ratio of T. baccata seeds, but increased N content and the N/P ratio; however, it did lower the C/N ratio in J. communis. Fertilisation did not change the metabolite profile in T. baccata but 18 metabolites were changed in J. communis. The study revealed new links between species life history, environmental changes, and reproduction. The findings imply that future environmental conditions may alter both seed productivity, and quality, as well as plant reproductive behaviour.
