Genetic Signature Controlling Root System Architecture in Diverse Spring Wheat Germplasm Physiol. Plant (IF 6.4) Pub Date : 2024-02-11 Zahra Zaman, Rubab Iqbal, Abdul Jabbar, Nageen Zahra, Bilal Saleem, Aysha Kiran, Saman Maqbool, Awais Rasheed, Muhammad Kashif Naeem, Muhammad Ramzan Khan
Roots are the main sensing organ, initiating multiple signaling pathways in response to abiotic factors, including nutrients, drought, and salt stress. A focus on improving the root system architecture is a key strategy to mitigate these stresses in wheat crop. In the present study, a diversity panel comprising indigenous landraces and historical cultivars from Pakistan was characterized for the root

Different metabolic adaptation strategies after overwintering in Eutrema sp. and Arabidopsis accessions under field conditions in Germany Physiol. Plant (IF 6.4) Pub Date : 2024-02-11 Ellen Zuther, Alexander Erban, Joachim Kopka, Majken Pagter
Successful overwintering is a prerequisite for high fitness in temperate perennials and winter annuals and is highly dependent on increased freezing tolerance and timely balancing of deacclimation with growth resumption in spring. To assess fitness costs associated with overwintering and elucidate metabolic mechanisms underlying winter survival and the switch from acclimated freezing tolerance to growth

SlPHL1 positively modulates acid phosphatase in response to phosphate starvation by directly activating the genes SlPAP10b and SlPAP15 in tomato Physiol. Plant (IF 6.4) Pub Date : 2024-02-12 Yanan Liu, Chengquan Li, Duanmei Zhang, Shaoxuan Huang, Yi Wang, Enhui Wang, Lin Zhu, Mingxue Chen, Xinyao Zhang, Rui Yuan, Lang Zhang, Wei Wang, Qi Jia, Zhongjuan Liu, Yongqiang Zhang
Increased acid phosphatase (APase) activity is a prominent feature of tomato (Solanum lycopersicum) responses to inorganic phosphate (Pi) restriction. SlPHL1, a phosphate starvation response (PHR) transcription factor, has been identified as a positive regulator of low Pi (LP)-induced APase activity in tomato. However, the molecular mechanism underlying this regulation remains to be elucidated. Here

A cotton APS REDUCTASE represses root hair elongation via sulfur assimilation and hydrogen peroxide-mediated cell wall damage Physiol. Plant (IF 6.4) Pub Date : 2024-02-07 Xiaonan Mao, Zhenzhen Wei, Zhenzhen Xu, Ghulam Qanmber, Ji Liu, Yonghui Li, Lili Lu, Ye Wang, Jun Peng, Zhi Wang
Sulfur is a critical element for plant growth and development, and it is assimilated through a pathway called the sulfur assimilation pathway. APS REDUCTASE (APR) is a key rate-limiting enzyme in this pathway, and it plays a vital role in regulating sulfur flow and plant development. However, the exact role and mechanism of APR in cotton fiber and root hair development are still not fully understood

Metabolomics Analyses Revealed the Key Metabolites and Pathways of Panax notoginseng under Heavy Drought Stress Physiol. Plant (IF 6.4) Pub Date : 2024-02-07 Shuai Zhang, Kuan Yang, Kunhao Ye, Huiling Wang, Youyong Zhu, Xiahong He, Liwei Guo
Drought is the most common abiotic stress that hinders plantgrowth. To clarify the changes in the growth and metabolism of Panax notoginseng following drought stress, here the effects of drought stress on the growth and metabolism of P. notoginseng are investigated using gas chromatography–mass spectrometry based on a widely targeted metabolomic approach. We conducted drought stress treatments (DS)

Ascorbate-glutathione cycle alleviates low-temperature-induced oxidative stress for augmented growth of Nannochloropsis oceanica Rose Bengal mutants Physiol. Plant (IF 6.4) Pub Date : 2024-02-08 Tsung-Yu Tsai, Inna Khozin-Goldberg, Avigad Vonshak, Tse-Min Lee
Studying the adaptive mechanisms of algae to abiotic stresses, such as low temperature and high light intensities, can help facilitate large-scale outdoor production. Consequently, the role played by the antioxidant defense system in the tolerance of Nannochloropsis oceanica Rose Bengal (RB) mutants, with a truncated PSII complex, to low-temperature (LT, 18°C) under high-light (HL, 250 μmol⋅m−2⋅s−1)

Accumulation of reactive carbonyl species in roots as the primary cause of salt stress-induced growth retardation of Arabidopsis thaliana Physiol. Plant (IF 6.4) Pub Date : 2024-02-08 Most. Sharmin Sultana, Chisato Sakurai, Md. Sanaullah Biswas, László Szabados, Jun'ichi Mano
Salt stress on plants induces an increase in reactive oxygen species (ROS), which then leads to the formation of reactive carbonyl species (RCS) such as acrolein and 4-hydroxy-(E)-2-nonenal (HNE), potent cytotoxins generated from lipid peroxides. We recently showed that salt-stress treatment of Arabidopsis thaliana plants increased RCS levels, and exogenously added RCS-scavenging chemicals alleviated

Temperature-smart plants: A new horizon with omics-driven plant breeding Physiol. Plant (IF 6.4) Pub Date : 2024-02-06 Ali Raza, Shanza Bashir, Tushar Khare, Benjamin Karikari, Rhys G. R. Copeland, Monica Jamla, Saghir Abbas, Sidra Charagh, Spurthi N. Nayak, Ivica Djalovic, Rosa M. Rivero, Kadambot H. M. Siddique, Rajeev K. Varshney
The adverse effects of mounting environmental challenges, including extreme temperatures, threaten the global food supply due to their impact on plant growth and productivity. Temperature extremes disrupt plant genetics, leading to significant growth issues and eventually damaging phenotypes. Plants have developed complex signaling networks to respond and tolerate temperature stimuli, including genetic
