Summary

Plant-environment interactions are important determinants of agroecosystem performance. Unraveling the intricacy of these interconnections is a big scientific problem, especially for optimizing agroecosystem systems. We highlight recent advances and new techniques in this special issue that contribute to the knowledge of the interactions between crops and their environment (biotic and abiotic factors, management practices, climate change, and so on) in order to improve crop yield and quality, soil sustainability, and water quality. Plant physiology, metabolism, and soil fertility are all likely to be impacted by climate change. Plant growth, fertility, and production are all hampered as a result of this. To ensure the long-term viability of ecosystems, we must improve our understanding of molecules that drive important processes and may play a role in plant stress resilience mechanisms.

（This article belongs to this Special Issue: Plant–Environment Interactions)
Abstract Pollination biology studies of the endangered herbal medicines Dendrobium chrysotoxum were conducted in natural pollination conditions using flower observation, pollinator observation and artificial pollination experiments. Populations of D. chrysotoxum with fragrance and nectar were pollinated by Ctenoplectra davidi Valhalla (Hymenoptera: Apidae) species. The floral structure of D. chrysotoxum adapted precisely to its pollinators. Flowers had a low capsule setting (0.17%) under natural conditions. However, compared to open pollination, artificial pollination experiments showed a significant increase in capsule setting, and D. chrysotoxum was cross-compatible and self-compatible, but there was pollinator limitation also. This study will provide important information for the preservation… More >

Abstract Plant species recognition is an important research area in image recognition in recent years. However, the existing plant species recognition methods have low recognition accuracy and do not meet professional requirements in terms of recognition accuracy. Therefore, ShuffleNetV2 was improved by combining the current hot concern mechanism, convolution kernel size adjustment, convolution tailoring, and CSP technology to improve the accuracy and reduce the amount of computation in this study. Six convolutional neural network models with sufficient trainable parameters were designed for differentiation learning. The SGD algorithm is used to optimize the training process to avoid overfitting or falling into the… More >

Do Geographically Isolated Grasslands Follow the Principle of Island Biogeography in a Landscape Scale? Taking Poyang Lake Grassland as an Example
Shiqi Luo, Wenbo Chen, Lei He, Qiongbing Xiong
Phyton-International Journal of Experimental Botany, Vol.92, No.2, pp. 455-470, 2023, DOI:10.32604/phyton.2022.022466
（This article belongs to this Special Issue: Plant–Environment Interactions)
Abstract As one of the basic theories of biodiversity conservation, island biogeography has been widely accepted in the past decades. Originally, island biogeography was put forward and applied in oceanic environments. But later on, it was found out that the application was not only limited to oceanic islands, but also in terrestrial environments with relatively isolated conditions. In terms of biodiversity level, island biogeography generally focuses on a small scale, such as species diversity and genetic diversity. The studies of biodiversity on a large-scale based on island biogeography, such as ecosystem and landscape scales, were seldomly conducted. Taking Poyang Lake, the… More >

Abstract Gray blight disease (GBD) causes significant losses in tea production in China. Although genes and biological processes involved in resistance to fungal disease in tea plants have been identified, specific mechanisms of the GBD infection process remain unknown. In this study, morphological and multi-gene (TEF-TUB-ITS) phylogenetic characteristics were used to identify isolate CLBB1 of Pseudopestalotiopsis vietnamensis. Pathogenicity tests confirmed that isolate CLBB1 from tea leaves caused GBD in the susceptible tea cultivar Wuyi Rock (Camellia sinensis var. sinensis cv. Shuixian). Spores began to germinate 24 h after infection (hai), and after 48 h, elongated fungal hyphae formed from a single conidium. Transcriptome… More >

Abstract Ecological interactions between flowers and pollinators greatly affect the reproductive success. To facilitate these interactions, many flowers are known to display their attractive qualities, such as scent emission, flower rewards and floral vertical direction, in a rhythmic fashion. However, less is known about how plants regulate the relationship between these flower traits to adapt to pollinator visiting behavior and increase reproduction success. Here we investigated the adaptive significance of the flower bending from erect to downward in Trifolium repens. We observed the flowering dynamic characteristics (changes of vertical direction of florets, flowering number, pollen grain numbers, pollen viability and stigma… More >
