An efficient in vitro organogenesis protocol for the endangered relic tree species Bretschneidera sinensis and genetic fidelity assessment using DNA markers Front. Plant Sci. (IF 5.6) Pub Date : 2024-04-10 Xuetong Yan, Keyuan Zheng, Peng Li, Xin Zhong, Zongwei Zhu, Huijing Zhou, Mulan Zhu
Bretschneidera sinensis is a monotypic species of rare and tertiary relic trees mainly distributed in China. B. sinensis is a potentially valuable horticultural plant, which has significant ornamental and research value, and is a crucial tool for the study of phylogeography. The artificial cultivation of B. sinensis is of great scientific value and practical significance. In this study, we developed

Fruits hidden by green: an improved YOLOV8n for detection of young citrus in lush citrus trees Front. Plant Sci. (IF 5.6) Pub Date : 2024-04-10 Gao Ang, Tian Zhiwei, Ma Wei, Song Yuepeng, Ren Longlong, Feng Yuliang, Qian Jianping, Xu Lijia
In order to address the challenges of inefficiency and insufficient accuracy in the manual identification of young citrus fruits during thinning processes, this study proposes a detection methodology using the you only look once for complex backgrounds of young citrus fruits (YCCB-YOLO) approach. The method first constructs a dataset containing images of young citrus fruits in a real orchard environment

Use of an automatic fruit-zone cooling system to cope with multiple summer stresses in Sangiovese and Montepulciano grapes Front. Plant Sci. (IF 5.6) Pub Date : 2024-04-10 Gabriele Valentini, Gianluca Allegro, Chiara Pastore, Daniela Sangiorgio, Massimo Noferini, Enrico Muzzi, Ilaria Filippetti
Grapevines are frequently subjected to heatwaves and limited water availability during ripening. These conditions can have consequences for the physiological health of the vines. Moreover, the situation is often exacerbated by intense solar radiation, resulting in reduced yield due to sunburn and a decline in quality. In light of these challenges, our study aimed to develop a fruit-zone cooling system

Analysis of huanglongbing-associated RNA-seq data reveals disturbances in biological processes within Citrus spp. triggered by Candidatus Liberibacter asiaticus infection Front. Plant Sci. (IF 5.6) Pub Date : 2024-04-10 Ruimin Li, Xinyou Wang, Yanan Hu, Guiyan Huang
IntroductionHuanglongbing (HLB), a disease that’s ubiquitous worldwide, wreaks havoc on the citrus industry. The primary culprit of HLB is the gram-negative bacterium Candidatus Liberibacter asiaticus (CLas) that infects the phloem, but its damaging mechanism is yet to be fully understood.Methods and resultsIn this study, a multitude of tools including weighted correlation network analysis (WGCNA)

Intraspecific variation in fine-root traits is larger than in aboveground traits in European herbaceous species regardless of drought Front. Plant Sci. (IF 5.6) Pub Date : 2024-04-10 Slendy Rodríguez-Alarcón, Riin Tamme, Carlos P. Carmona
Differences within species (Intraspecific trait variation - ITV) contribute substantially to overall trait variability and environmental harshness can reduce among-species variation. While aboveground traits have received considerable attention, knowledge about ITV in fine-root traits and how it differs from ITV in aboveground traits remains limited. This study examined the partitioning of trait variation

Patterns and drivers of plant carbon, nitrogen, and phosphorus stoichiometry in a novel riparian ecosystem Front. Plant Sci. (IF 5.6) Pub Date : 2024-04-09 Lei Wang, Muhammad Arif, Jie Zheng, Changxiao Li
Carbon (C), nitrogen (N), and phosphorus (P) stoichiometry serve as valuable indices for plant nutrient utilization and biogeochemical cycling within ecosystems. However, the allocation of these nutrients among different plant organs and the underlying drivers in dynamic riparian ecosystems remain inadequately understood. In this study, we gathered plant samples from diverse life forms (annuals and

Elevated CO2 and ammonium nitrogen promoted the plasticity of two maple in great lakes region by adjusting photosynthetic adaptation Front. Plant Sci. (IF 5.6) Pub Date : 2024-04-09 Lei Wang, Qing-Lai Dang
IntroductionClimate change-related CO2 increases and different forms of nitrogen deposition are thought to affect the performance of plants, but their interactions have been poorly studied.MethodsThis study investigated the responses of photosynthesis and growth in two invasive maple species, amur maple (Acer ginnala Maxim.) and boxelder maple (Acer negundo L.), to elevated CO2 (400 µmol mol-1 (aCO2)

Tomato leaf disease detection based on attention mechanism and multi-scale feature fusion Front. Plant Sci. (IF 5.6) Pub Date : 2024-04-09 Yong Wang, Panxing Zhang, Shuang Tian
When detecting tomato leaf diseases in natural environments, factors such as changes in lighting, occlusion, and the small size of leaf lesions pose challenges to detection accuracy. Therefore, this study proposes a tomato leaf disease detection method based on attention mechanisms and multi-scale feature fusion. Firstly, the Convolutional Block Attention Module (CBAM) is introduced into the backbone

Amphibian skin bacteria display antifungal activity and induce plant defense mechanisms against Botrytis cinerea Front. Plant Sci. (IF 5.6) Pub Date : 2024-04-09 Yordan J. Romero-Contreras, Francisco Gonzalez-Serrano, Damien Formey, Wendy Aragón, Florencia Isabel Chacón, Martha Torres, Miguel Ángel Cevallos, Julian Rafael Dib, Eria A. Rebollar, Mario Serrano
Botrytis cinerea is the causal agent of gray mold, which affects a wide variety of plant species. Chemical agents have been used to prevent the disease caused by this pathogenic fungus. However, their toxicity and reduced efficacy have encouraged the development of new biological control alternatives. Recent studies have shown that bacteria isolated from amphibian skin display antifungal activity against
