A Critical Review of Conventional and Modern Approaches to Develop Herbicide‐Resistance in Rice Physiol. Plant (IF 6.4) Pub Date : 2024-03-19 Shifei Sang, Yanan Wang, Guoqin Yao, Tengyun Ma, Xiaohan Sun, Yijing Zhang, Nan Su, Xiaoyu Tan, Hafiz Muhammad Khalid Abbas, Shengdong Ji, Qamar U. Zaman
Together with rice, weeds strive for nutrients and space in farmland, resulting in reduced rice yield and quality. Planting herbicide‐resistant rice varieties is one of the effective ways to control weeds. In recent years, a series of breakthroughs have been made to generate herbicide‐resistant germplasm, especially the emergence of biotechnological tools such as gene editing, which provides an inherent

Trade‐offs between root‐secreted acid phosphatase and root morphology traits, and their contribution to phosphorus acquisition in Brassica napus Physiol. Plant (IF 6.4) Pub Date : 2024-03-19 Hao Li, Chuang Wang, Bingbing Zhang, Haijiang Liu, John P. Hammond, Xiaohua Wang, Guangda Ding, Hongmei Cai, Sheliang Wang, Fangsen Xu, Lei Shi
Oilseed rape (Brassica napus) is one of the most important oil crops in the world and shows sensitivity to low phosphorus (P) availability. In many soils, organic P (Po) is the main component of the soil P pool. Po must be mineralised to Pi through phosphatases, and then taken up by plants. However, the relationship between root‐secreted acid phosphatases (APase) and root morphology traits, two important

Metabolome and Transcriptome Reveal Chlorophyll, Carotenoid, and Anthocyanin Jointly Regulate the Color Formation of Triadica sebifera Physiol. Plant (IF 6.4) Pub Date : 2024-03-16 Qing Liu, Leijia Wang, Lina He, Yongkang Lu, Lin Wang, Songling Fu, Xumei Luo, Yanping Zhang
The Chinese tallow tree (Triadica sebifera) is an economically important plant on account of its ornamental value and oil‐producing seeds. Leaf colour is a key characteristic of T. sebifera, with yellow‐, red‐ and purple‐leaved varieties providing visually impressive displays during autumn. In this study, we performed metabolomic and transcriptomic analyses to gain a better understanding of the mechanisms

Multi‐omics analysis reveals the biosynthesis of flavonoids during the browning process of Malus sieversii explants Physiol. Plant (IF 6.4) Pub Date : 2024-03-16 Chen Yang, Nan Sun, Xin Qin, Yangbo Liu, Mengyi Sui, Yawen Zhang, Yanli Hu, Zhiquan Mao, Xuesen Chen, Yunfei Mao, Xiang Shen
Malus sieversii is a precious apple germplasm resource. Browning of explants is one of the most important factors limiting the survival rate of plant tissue culture. In order to explore the molecular mechanism of the browning degree of different strains of Malus sieversii, we compared the dynamic changes of Malus sieversii and Malus robusta Rehd. during the whole browning process using a multi‐group

Sequence similarity networks bear out hierarchical relationships of green cytochrome P450 Physiol. Plant (IF 6.4) Pub Date : 2024-03-14 Amra Dhabalia Ashok, Jella N. Freitag, Iker Irisarri, Sophie de Vries, Jan de Vries
Land plants have diversified enzyme families. One of the most prominent is the cytochrome P450 (CYP or CYP450) family. With over 443,000 CYP proteins sequenced across the tree of life, CYPs are ubiquitous in archaea, bacteria, and eukaryotes. Here, we focused on land plants and algae to study the role of CYP diversification. CYPs, acting as monooxygenases, catalyze hydroxylation reactions crucial for

Coordination of pinna, petiole, and root anatomical traits in 24 tropical‐subtropical fern species Physiol. Plant (IF 6.4) Pub Date : 2024-03-14 Dong‐Liu Huang, Wei Xiang, Hui Liu, Shi‐Dan Zhu
Ferns are primitive vascular plants with diverse morphologies and structures. Plant anatomical traits and their linkages can reflect adaptation to the environment; however, these remain are still poorly understood in ferns. The main objective of this study was to explore whether there was structural coordination among and within organs in fern species. We measured 16 hydraulically related anatomical

Tight coupling between leaf δ13C and N content along leaf ageing in the N2‐fixing legume tree black locust (Robinia pseudoacacia L.) Physiol. Plant (IF 6.4) Pub Date : 2024-03-13 Wei Ren, Lide Tian, José Ignacio Querejeta
N2‐fixing legumes can strongly affect ecosystem functions by supplying nitrogen (N) and improving the carbon‐fixing capacity of vegetation. Still, the question of how their leaf‐level N status and carbon metabolism are coordinated along leaf ageing remains unexplored. Leaf tissue carbon isotopic composition (δ13C) provides a useful indicator of time‐integrated intrinsic water use efficiency (WUEi)

Fulvic acid alleviates the stress of low nitrogen on maize by promoting root development and nitrogen metabolism Physiol. Plant (IF 6.4) Pub Date : 2024-03-13 Yuanyuan Liang, Junbo Wang, Zeping Wang, Desheng Hu, Ying Jiang, Yanlai Han, Yi Wang
The potential of fulvic acid (FA) to improve plant growth has been acknowledged, but its effect on plant growth and nutrient uptake under nutrient stress remains unclear. This study investigated the effects of different FA application rates on maize growth and nitrogen utilization under low nitrogen stress. The results showed that under low nitrogen stress, FA significantly stimulated maize growth

NRG2 family members of Arabidopsis and maize regulate nitrate signalling and promote nitrogen use efficiency Physiol. Plant (IF 6.4) Pub Date : 2024-03-13 Shuna Li, Meiling Ji, Fei Liu, Mingyue Zhu, Yi Yang, Wenjing Zhang, Shubing Liu, Yong Wang, Wei Lv, Shengdong Qi
Nitrogen (N) is an essential nutrient for plant growth, and most plants absorb it as nitrate. AtNRG2 has been reported to play an important role in nitrate regulation. In this study, we investigated the functions of AtNRG2 family members of Arabidopsis thaliana and maize in nitrate signalling and metabolism. Our results showed that both AtNRG2.10 and AtNRG2.15 regulated nitrate signalling and metabolism

Endophytic Fungi‐Mediated Defense Signaling in Maize: Unraveling the Role of WRKY36 in Regulating Immunity against Spodoptera frugiperda Physiol. Plant (IF 6.4) Pub Date : 2024-03-12 Raufa Batool, Gou Xuelian, Dong Hui, Long Xiuzhen, Muhammad Jawad Umer, Ivan Rwomushana, Abid Ali, Kotb A. Attia, Guo Jingfei, Wang Zhenying
Seed priming with beneficial endophytic fungi is an emerging sustainable strategy for enhancing plant resistance against insect pests. This study examined the effects of Beauvaria bassiana Bb20091317 and Metarhizium rileyi MrCDTLJ1 fungal colonization on maize growth, defence signalling, benzoxazinoid levels and gene expression. The colonization did not adversely affect plant growth but reduced larval
