“…It is widely used in the production of solid wood and resin 20 . Masson pine often suffers abiotic and biotic stress during its life cycle 21 . Pine wood nematode ( Bursaphelenchus xylophilus ) is the main causative pathogen, and PWN disease is a damaging disease that jeopardozes pine, included Masson pine 22 .…”

Transcription factors (TFs) play crucial regulatory roles in controlling the expression of the target genes in plants. APETALA2/Ethylene-responsive factors (AP2/ERF) are part of a large superfamily of plant-specific TFs whose members are involved in the control of plant metabolism, development and responses to various biotic and abiotic stresses. However, the AP2/ERF superfamily has not been identified systematically in Masson pine (Pinus massoniana), which is one of the most important conifer in southern China. Therefore, we performed systematic identification of the AP2/ERF superfamily using transcriptome sequencing data from Masson pine. In the current study, we obtained 88 members of the AP2/ERF superfamily. All PmAP2/ERF members could be classified into 3 main families, AP2 (7 members), RAV (7 members), ERF (73 members) families, and a soloist protein. Subcellular localization assays suggested that two members of PmAP2/ERF were nuclear proteins. Based on pine wood nematode (PWN) inoculated transcriptome and qPCR analysis, we found that many members of PmAP2/ERF could respond to PWN inoculation and PWN related treatment conditions in vitro. In general, members of the AP2/ERF superfamily play an important role in the response of Masson pine responds to PWN. Furthermore, the roles of the AP2/ERF superfamily in other physiological activities of Masson pine remain to be further studied.

“…9 × 10 7 ha according to the eighth National Forest Resources Inventory survey; this amount accounts for approximately a quarter of the world’s plantation area ( Chen et al, 2015 ; Mo et al, 2020 ). Pinus massoniana Lamb., as an important fast-growing economic timber species in southern China, is widely distributed in the northern subtropics, mid-subtropics, southern subtropics and northern tropics of China and occupies an extremely important position in forestry production and forests ( Li et al, 2019 ; Huang et al, 2020 ). P. massoniana is a pioneer tree species in community succession in the low mountain and hilly region of eastern Sichuan because of its strong adaptability and resistance to drought and barren land; however, the large, single-species forests of P. massoniana combined with improper forest management measures, have led to differentiation of the internal ecological microenvironment.…”

As one means of close-to-nature management, forest gaps have an important impact on the ecological service function of plantations. To improve the current situation of P. massoniana plantations, three different sizes of forest gaps (large gaps, medium gaps and small gaps) were established to observe whether gap setting can improve the soil fertility and plant diversity of forest plantations. The results showed that compared with the control, the soil organic matter content of different soil layers increased significantly in the medium forest gap and large forest gap. The content of soil organic matter in the surface layer of the middle gap had the largest increase (80.64%). Compared with the control, the content of soil-available potassium between different soil layers decreased significantly by 15.93% to 25.80%. The soil hydrolysable nitrogen reached its maximum under the medium gap. Soil moisture showed significant changes among different gap treatments, different soil layers and their interaction, decreasing significantly in large gaps and small gaps but increasing significantly in medium gaps. The soil bulk density decreased significantly compared with the control, and the surface soil reached the minimum in the medium gap. There were different plant species in forest gaps of different sizes, and shrub layer plants were more sensitive to gap size differences than herb layer plants. The plant diversity indices of the shrub layer increased significantly and showed a maximum under the medium gap. The plant diversity of the herb layer showed the opposite trend, and the Shannon-Wiener index, Simpson index and Pielou index were significantly lower than those of the control. RDA showed that different gap treatments had significant effects on the distribution of plants under the forest. Soil available potassium, soil moisture and soil bulk density affected the distribution and diversity of plants under the forest, serving as the limiting factors of plant growth. In forest management, if we strictly consider the improvement of plant diversity and soil physicochemical properties, these results suggest that a medium gap should be established in a plantation for natural restoration.

“…These conditions may cause a decrease in carbohydrate availability and a decreased growth rate (Michelot et al, 2012;Zhang et al, 2021). Relevant studies based on tree rings and stable carbon isotope have also confirmed the negative effect of summer drought on tree growth on an interannual scale (Li et al, 2019;Bai et al, 2020;Dong et al, 2020).…”

Monitoring cambial activity is important for a better understanding of the mechanisms governing xylem growth responses to climate change, providing a scientific basis for tree-ring-based climate reconstructions and projections about tree growth under future climate scenarios. It plays an even more important role in investigating evergreen tree growth in regions with less distinct seasonal cycles. Subtropical evergreen forests have been studied in recent years for their sensitivity to climate change, but it remains unclear how xylem growth is driven by subtropical climates. To further understand the climate-growth response strategies of subtropical conifers, we micro-cored Cryptomeria fortunei and Cunninghamia lanceolata weekly in 2016 and 2017 at the humid subtropical Gushan Mountain in southeastern China. Our weekly growth monitoring showed that the vegetation periods of these two species were both approximately 2–3 months longer than trees in temperate and boreal forests. The growth of C. fortunei in 2016 and 2017 and C. lanceolata in 2017 showed a bimodal pattern of xylogenesis, which was induced by summer drought. The results also indicated that the earlier end of the xylem formation was related to the yearly drought stress. These findings provide more specific information about tree growth and evidence of how climate influences wood production at the cellular level in subtropical regions.
