Nanoparticles regulate redox metabolism in plants during abiotic stress within hormetic boundaries Funct. Plant Biol. (IF 3.0) Pub Date : 2023-09-28 Saswati Bhattacharya, Sumanti Gupta, Jayita Saha
Abiotic stress management remains under scrutiny because of the unpredictable nature of climate, which undergoes abrupt alterations. Population pressure, loss of cultivable lands, environmental pollution and other anthropogenic disturbances add to the problem and grossly hinder ongoing management strategies. This has driven increasing effort to find better performing, eco-friendly and reliable alternatives

The metabolic response of Araucaria angustifolia embryogenic cells to heat stress is associated with their maturation potential Funct. Plant Biol. (IF 3.0) Pub Date : 2023-09-25 Fernando Diego Kaziuk, Ana Luiza Dorigan de Matos Furlanetto, André Luis Wendt dos Santos, Eny Iochevet Senegal Floh, Lucelia Donatti, Maria Eliane Merlin Rocha, Fabiane Fortes, Glaucia Regina Martinez, Silvia Maria Suter Correia Cadena
Araucaria angustifolia is a critically endangered species and its distribution can be affected by an increase in temperature. In this study, we evaluated the effects of heat stress (30°C) on Araucaria angustifolia cell lines responsive (SE1) and non-responsive (SE6) to the development of somatic embryos. The viability of both cell lines was reduced by heat stress and mitochondria were the organelles

Effect of salt, alkali and combined stresses on root system architecture and ion profiling in a diverse panel of oat (Avena spp.) Funct. Plant Biol. (IF 3.0) Pub Date : 2023-09-25 Shahid Ahmed, Richa Patel, Maneet Rana, Neeraj Kumar, Indu I, Mukesh Choudhary, Subhash Chand, Amit Kumar Singh, Avijit Ghosh, Rajesh Kumar Singhal
The co-occurrence of salinisation and alkalisation is quite frequent in problematic soils and poses an immediate threat to food, feed and nutritional security. In the present study, root system architectural traits (RSAs) and ion profiling were evaluated in 21 genotypes of Avena species to understand the effect of salinity–alkalinity stress. The oat genotypes were grown on germination paper and 5-day-old

Measuring residual transpiration in plants: a comparative analysis of different methods Funct. Plant Biol. (IF 3.0) Pub Date : 2023-09-20 Md. Hasanuzzaman, Koushik Chakraborty, Meixue Zhou, Sergey Shabala
Residual transpiration (RT) is defined as a loss of water through the leaf cuticle while stomata are closed. Reduced RT might be a potentially valuable trait for improving plant performance under water deficit conditions imposed by either drought or salinity. Due to the presence of stomata on the leaf surface, it is technically challenging to measure RT. RT has been estimated by the water loss through

Sunlight-induced repair of photosystem II in moss Semibarbula orientalis under submergence stress Funct. Plant Biol. (IF 3.0) Pub Date : 2023-09-12 Upma Bhatt, Shubhangani Sharma, Hazem M. Kalaji, Reto J. Strasser, Chrystian Chomontowski, Vineet Soni
Lower plants such as bryophytes often encounter submergence stress, even in low precipitation conditions. Our study aimed to understand the mechanism of submergence tolerance to withstand this frequent stress in moss (Semibarbula orientalis) during the day and at night. These findings emphasise that light plays a crucial role in photoreactivation of PSII in S. orientalis, which indicates that light

BrRD20 improves abiotic stress resistance in chrysanthemum Funct. Plant Biol. (IF 3.0) Pub Date : 2023-09-12 Zhao Xue, Jierui Zhang, Xin Li, Xuelei Qian, Haifang Yan
RESPONSIVE TO DESSICATION 20 (RD20) is a member of the caleosin family, which is involved in plant growth and development, signal transduction, abiotic stress and plant immunity. However, the molecular mechanism of the biological function of RD20 in turnip is still largely unknown. This study aimed to characterise the roles of BrRD20 during abiotic stress resistance and their responses in various abiotic

Combinatorial transcriptomics and metabolomics analysis reveals the effects of the harvesting stages on the accumulation of phenylpropanoid metabolites in Lonicera japonica Funct. Plant Biol. (IF 3.0) Pub Date : 2023-08-23 Zhifang Ran, Weina Ding, Hongxia Yu, Li Zhang, Lei Fang, Lanping Guo, Jie Zhou
The flower buds of Lonicera japonica are widely used for its high medicinal value. It is reported that the accumulation of phenylpropanoids in the buds of L. japonica is affected by the stage at which it is harvested. However, the changes of active components and the underlying mechanisms in flower buds at different harvesting stages have not been reported. Integrative analyses of transcriptomics and

Survival analysis of germination data in response to temperature for Ornithopus species and other temperate pasture legumes Funct. Plant Biol. (IF 3.0) Pub Date : 2023-08-22 D. R. Kidd, M. Valifard, Juan Qi, J. M. B. Wisdom, R. J. Simpson, M. H. Ryan
Cool temperatures can limit productivity of temperate grazing systems as poor pasture growth rates in winter create feed shortages for livestock. Ornithopus spp. (serradella) are broadly adapted annual pasture legumes that produce high-quality forage in soil types considered marginal for other temperate legume species. However, serradella establishment is perceived to be difficult in cool-season environments

Zinc and nano zinc mediated alleviation of heavy metals and metalloids in plants: an overview Funct. Plant Biol. (IF 3.0) Pub Date : 2023-08-21 Sanaullah Jalil, Muhammad Mudassir Nazir, Qurban Ali, Faisal Zulfiqar, Anam Moosa, Muhammad Ahsan Altaf, Abbu Zaid, Muhammad Nafees, Jean Wan Hong Yong, Xiaoli Jin
Heavy metals and metalloids (HMs) contamination in the environment has heightened recently due to increasing global concern for food safety and human livability. Zinc (Zn2+) is an important nutrient required for the normal development of plants. It is an essential cofactor for the vital enzymes involved in various biological mechanisms of plants. Interestingly, Zn2+ has an additional role in the detoxification

Salt tolerance in Brassicaceae crops: physiological responses and molecular mechanisms Funct. Plant Biol. (IF 3.0) Pub Date : 2023-08-18 Tenghui Wang, Xuyan Yang, Zhenyu Fan, Yushu Wang
Soil salinisation is a growing threat to global agriculture, reducing crop yields. Brassicaceae crops are vital vegetables and cash crops. Salt stress significantly affects the growth and development of Brassicaceae crops. A better understanding of the molecular and physiological mechanisms of salt tolerance is of theoretical and practical importance to improve Brassicaceae crop’s salt tolerance and

Effects of iron oxide nanoparticles (Fe 3 O 4 ) and salinity on growth, photosynthesis, antioxidant activity and distribution of mineral elements in wheat (Triticum aestivum) Funct. Plant Biol. (IF 3.0) Pub Date : 2023-08-14 Vladimir D. Kreslavski, Alexander N. Shmarev, Anatoly A. Ivanov, Sergey K. Zharmukhamedov, Valeria Strokina, Anatoly Kosobryukhov, Min Yu, Suleyman I. Allakhverdiev, Sergey Shabala
Soil salinisation is one of the main abiotic stresses decreasing crop productivity. Here, we show that the plant treatment with iron oxide (Fe3O4) nanoparticles (NPs) may be a promising solution for reducing the negative impact of soil salinity on plant performance. For this purpose, effects of the NPs on growth, photosynthesis, pro-/antioxidant, redox balance and the content of mineral elements in

Drought and salinity are the main factors limiting agricultural production. Improving crop resistance to relieve land stress is a major challenge in agriculture. The salt-tolerant species Suaeda salsa is a typical indicator of saline soil. It has a strong drought tolerance and can be used as a model plant to study salt and drought tolerance in plants. In this study, transcriptome sequencing and bioinformatic
