Shading treatment during late stage of seed development promotes subsequent seed germination and seedlings establishment in sunflower Plant Sci. (IF 5.2) Pub Date : 2024-01-24 Yutao Huang, Gaofu Mei, Kehua Zhu, Xiaoli Ruan, Huaping Wu, Dongdong Cao
During the sunflower seed production process, the role of artificial shading treatment (ST) in seed development and subsequent seed germination remains largely unknown. In the present study, sunflower mother plants were artificially shaded during 1–34 (full period-ST, FST), 1–22 (early period-ST, EST), and 22–34 (late period-ST, LST) days after pollination (DAP), to examine the effects of parental

The roles of non-coding RNAs in male reproductive development and abiotic stress responses during this unique process in flowering plants Plant Sci. (IF 5.2) Pub Date : 2024-01-23 Dexi Shi, Huiting Huang, Yuting Zhang, Zhihao Qian, Jiao Du, Li Huang, Xiufeng Yan, Sue Lin
Successful male reproductive development is the guarantee for sexual reproduction of flowering plants. Male reproductive development is a complicated and multi-stage process that integrates physiological processes and adaptation and tolerance to a myriad of environmental stresses. This well-coordinated process is governed by genetic and epigenetic machineries. Non-coding RNAs (ncRNAs) play pleiotropic

Review: Plant microRNAs in pathogen defense: A panacea or a piece of the puzzle? Plant Sci. (IF 5.2) Pub Date : 2024-01-22 Mohsen Asadi, Anthony A. Millar
Plant microRNAs (miRNAs) control key agronomic traits that are associated with their conserved role(s) in development. However, despite a multitude of studies, the utility of miRNAs in plant-pathogen resistance remains less certain. Reviewing the literature identifies three general classes of miRNAs regarding plant pathogen defense. Firstly, a number of evolutionary dynamic 22 nucleotide miRNA families

Evolutionary expansion, functional diversification, and transcript profiling of plant Glutathione Peroxidases Plant Sci. (IF 5.2) Pub Date : 2024-01-22 Al Imran, Ajit Ghosh
Glutathione peroxidases (GPXs) play a crucial role in combating activated oxygen species and have been widely studied for their involvement in stress responses. In addition to their stress-related functions, GPXs exhibit diverse roles such as immunological response, and involvement in growth and development. These enzymes are found in both animals and plants, with multiple families identified in the

VqNAC44 enhances stilbene synthesis and disease resistance in Chinese wild grape by interacting with VqMYB15 Plant Sci. (IF 5.2) Pub Date : 2024-01-21 Linxia Wang, Ming Zhang, Jia Li, Qin Luo, Qian Yao, Qiuyu Huang, Runxin Zhang, Dong Duan
As significant phytoalexins, stilbene compounds can improve the stress resistance of grapes under biotic and abiotic stress conditions and have biological effects such as antitumour, antioxidant, immune regulation and cardiovascular protection activities in humans. RESVERATROL SYNTHASE (RS), also known as STILBENE SYNTHASE (STS), is the critical enzyme regulating stilbene synthesis and has been identified

Characteristic analysis of BZR genes family and their responses to hormone treatments and abiotic stresses in Carya illinoinensis Plant Sci. (IF 5.2) Pub Date : 2024-01-20 Yirui Zhao, Haoyu Wang, Yifan Xu, Ketao Wang, Chunying Huang, Yangyong Deng, Jianqin Huang, Yan Li
As the core of Brassinosteroids (BR) signaling pathway, BR-resistant (BZR) transcription factor regulates thousands of targeted genes mediating photomophogenesis, pollen sterility, cell expansion and stress response. Pecan (Carya illinoinensis) is a famous trees species of Carya, and its nut has high nutritional and economic values. However, there has no report on BZR genes family in pecan yet. Herein

Transcriptomics combined with physiological analysis provided new insights into the Zn enrichment capacity and tolerance mechanism of Dendrobium denneanum Kerr Plant Sci. (IF 5.2) Pub Date : 2024-01-15 Yuanyuan Liu, Erya Xu, Yijun Fan, Linlong Xu, Jie Ma, Xuebing Li, Hui Wang, Siyu He, Ting Li, Yujiao Qin, Jingtao Xiao, Aoxue Luo
In this study, we investigated the tolerance and accumulation capacity of Dendrobium denneanum Kerr (D.denneanum) by analyzing the growth and physiological changes of D.denneanum under different levels of Zn treatments, and further transcriptome sequencing of D.denneanum leaves to screen and analyze the differentially expressed genes. The results showed that Zn400 treatment (400 mg·kg-1) promoted the
