Summary: In this study, a cytochrome P450 monooxygenase gene, PmCYP720B11v2, was identified and characterized from resistant Pinus massoniana. The gene was found to play a positive role in the defense against pinewood nematode attack by promoting diterpene biosynthesis. Overexpression of PmCYP720B11v2 also enhanced plant growth and development, as well as improved drought stress tolerance.

Summary: Studies on the dynamics of non-structural carbohydrates (NSCs) are important for understanding plant responses to drought stress. This study aimed to assess the influence of ectomycorrhizal fungi (ECMF) on NSC content and distribution in Pinus massoniana seedlings under different drought intensities. The results showed that ECMF enhanced the stress resistance of the seedlings by increasing NSCs storage, improving soluble sugar distribution, and improving the plant water balance. Moreover, ECMF also promoted the growth of the seedlings under drought stress.

Summary: This study found that the growth and stress response of Pinus massoniana are regulated by the AP2/ERF transcription factor family. A total of 124 AP2/ERF genes were identified, which had conserved structural domains and were classified into 12 subfamilies. Nine genes were constitutively expressed under drought treatment, and some genes showed positive or negative responses to drought in different tissues. Furthermore, the expression patterns of these genes differed when treated with exogenous hormones, but all responded by up-regulating expression under drought stress.

Summary: This study identified 49 R2R3-MYB transcription factors in Masson pine and compared their structure, function, and phylogenetic relationships with Populus trichocarpa TFs. The drought stress-responsive gene PmMYB4 was found to be involved in drought stress treatment through ABA signaling, as well as in salt stress and showed significant expression differences in different tissues. These findings provide a reference for functional identification of R2R3-MYB transcription factors and enhance our understanding of their role in plant stress responses.

Summary: In this study, 55 bZIP transcription factors were identified in Pinus massoniana and a systematic analysis was performed. The bZIP TFs of P. massoniana were divided into 11 groups based on phylogenetic analysis. Each bZIP protein contained a conserved bZIP domain and exhibited similar motif types and numbers within the same group. Transcriptional profiles revealed that 25 PmbZIP genes responded to pine wood nematodes at different levels. Among them, PmbZIP3, PmbZIP4, PmbZIP8, PmbZIP20, and PmbZIP23 were upregulated during the nematode inoculation process.

Summary: Drought stress is a threat to Pinus massoniana seedling growth in southern China. Inoculation of drought-resistant Trichoderma longibrachiatum significantly promotes plant growth under drought treatment and enhances nutrient absorption. Trichoderma longibrachiatum treatment also alleviates damage to cell membranes and increases antioxidant enzyme activities, osmotic substance contents, and photosynthesis in P. massoniana.

Summary: Biochar has been used as a cost-effective amendment to improve soil water content and mitigate the effects of drought on plants. However, its effects on trees during longer drought durations are still not well understood. In this greenhouse experiment, we found that the growth of Pinus massoniana saplings decreased with longer drought duration, likely due to suppressed photosynthetic capacity. Surprisingly, biochar application decreased sapling survival and exacerbated the negative effects of drought duration on P. massoniana growth, possibly because it increased soil pH.

Summary: Exogenous brassinosteroids promoted xylem development in Pinus massoniana seedlings, especially in a dosage-dependent manner within a certain concentration range. The study also showed interactions between BR and other phytohormones in regulating xylem development, as well as activation of new lignin synthesis pathways or other cell wall components by BR treatment.

Summary: Pinus massoniana, a species used in afforestation, has high economic, ecological, and therapeutic significance. This study identified 21 PmGRASs in the P. massoniana transcriptome and found that PmGRASs, especially PmGRAS9, PmGRAS10, and PmGRAS17, may play a crucial role in stress resistance. Tissue-specific expression analyses revealed that the majority of PmGRASs were significantly expressed in needles and may function at multiple locales and developmental stages.
