FP23244Biochemical and physiological time-of-day variations in early-development phase of Agave mapisaga and Agave salmiana

Jesus A. Jiménez-Torres 0000-0001-6231-6172, Cecilia B. Peña-Valdivia 0000-0003-4245-0547, Baruch Arroyo, Daniel Padilla-Chacón 0000-0001-9887-1063 and Rodolfo García
 

The morphological and physiological adaptations of Agave species, including the Classulacean acid metabolism (CAM), allow plants to develop in arid and semi-arid environments. Four diel phases have been described in CAM plants that regulate carbon metabolism, growth and yield. The hypothesis is that in early-development plants from seeds, growing under greenhouse conditions, of each genotype’s physiological responses, including growth and metabolites concentrations, vary among CAM phases because of the species of Agave and the seed provenance.

FP24135Expression of heterosis in photosynthetic traits in F1 generation of sorghum (Sorghum bicolor) hybrids and relationship with yield traits

Renjie Zhao, Yueqiao Li, Chen Xu, Zhian Zhang 0009-0003-3745-0734, Ziyang Zhou, Yihan Zhou and Zexin Qi
 

There is limited information on the hybridisation of enzymes linked to these characteristics. Understanding hybrid dominance of photosynthetic traits and their associated enzymes in sorghum is crucial for identifying sorghum hybrids with highly dominant combinations and selecting suitable parents. This study utilised 36 sorghum hybrid F1 generations and their respective parents to assess hybrid dominance in leaf photosynthetic parameters, key enzyme activities during photosynthesis, yield formation, and other relevant factors, while also examining their correlation with yield in field conditions.

FP24064Enhancing stress resilience in soybeans (Glycine max): assessing the efficacy of priming and cross-priming for mitigating water deficit and waterlogging effects

Adriano U. Bester, Eduardo P. Shimoia 0000-0002-2889-4259, Cristiane J. Da-Silva 0000-0003-3239-5927, Douglas A. Posso, Ivan R. Carvalho, Fernanda M. Corrêa, Ana C. B. de Oliveira and Luciano do Amarante
 

Priming is a method where the exposition of a plant to a mild stress before a severe one enables quicker stress response, and holds promise in mitigating water stress. This study assessed the efficacy of priming in combating waterlogging and dehydration in soybean (Glycine max) plants. Results revealed that priming significantly boosted antioxidant enzyme activity and organic compound levels while reducing oxidative damage. Such findings suggest that priming could help soybean cultivation, enhancing resilience against climate-induced adversities and ensuring global food security.

FP23089Canola (Brassica napus) enhances sodium chloride and sodium ion tolerance by maintaining ion homeostasis, higher antioxidant enzyme activity and photosynthetic capacity fluorescence parameters

Lupeng Sun, Xiaoqiang Cao, Juncan Du, Yan Wang and Fenghua Zhang 0000-0002-1666-9548
 

Both sodium chloride and sodium salt treatments inhibited the growth of canola seedlings. Sodium chloride imposed the most damage, and chloride salts the least. Under treatment with sodium chloride and sodium salt, the canola variety Huayouza 62 grew best, by maintaining lower sodium content in the root system, higher magnesium content, and a greater ratio of magnesium to sodium to improve photosynthetic capacity. Chloride salts had a positive role in inducing oxidative stress and responsive antioxidant defence in canola seedlings.

WOX is a family of genes that help regulate how plants develop and also respond to stress. In this study, 12 WOX genes were identified in grapes and analysed by bioinformatic methods. Coanalysis of different expression patterns in grapes showed that two of these genes respond to specific viruses and effectively block virus replication and infestation. Another gene was the most sensitive to salt stress. This study provides preliminary evidence that these three genes are key to resistance to salt and to viruses in grape, providing vital candidate genes for grapevine breeding

Abscisic acid (ABA) is a key player in how plants adapt to their environment, from growth to coping with stress. In this study, we identified the PYL genes in potatoes (Solanum tuberosum), crucial for ABA signalling pathways, yet poorly understood in potato. We uncover 17 PYL genes in potatoes, revealing their diverse roles in stress response and growth regulation. These findings shed light on potential role of PYL genes in mitigating the multiple stresses.

FP24108Effects of arbuscular mycorrhizal fungi in the rhizosphere of two olive (Olea europaea) varieties Arbequina and Barnea under water deficit conditions

Mariana Bonetto, Noelia Cofré 0000-0002-5696-6598, Franco Calvo and Sonia Silvente
 

We evaluated different water regimes on young cuttings of olive (Olea europaea) cvs Arbequina and Barnea inoculated with or without arbuscular mycorrhizal fungi (AMF) in a central-western olive grove in Argentina. We measured AMF morphospecies richness and abundance in the soil, plant vegetative growth, plant adaptation to drought stress, and crop water status. We found that certain morphological, physiological and biochemicalindicators may be useful to identify new strategies to mitigate water stress and improve water use efficiency during transplantation.

FP23325Heliotropium thermophilum adapts to high soil temperature in natural conditions due to its highly active antioxidant system protecting its photosynthetic machinery

Sevgi Bülbül, Asiye Sezgin Muslu 0000-0003-0899-0742, Aykut Saglam 0000-0003-4102-7990 and Asim Kadioglu
 

Heliotropium thermophilum did not exhibit significant stress parameters under high soil temperature conditions, and it was a highly tolerant plant to high temperature. In the measurements taken at pre-flowering and flowering, plants in the pre-flowering stage were slightly more tolerant to high temperatures. The protection of PSII function in plants at higher temperatures could be linked to an increase in antioxidant activities.

FP24058Acclimation mechanism of microalgal photosynthetic apparatus under low atmospheric pressures – new astrobiological perspectives in a Mars-like atmosphere

Charalampia-Stavroula Gritsi, Evangelos Sarmas, Vangelis Daskalakis 0000-0001-8870-0850 and Kiriakos Kotzabasis 0000-0002-1002-6365
 

This study reveals a new acclimation mechanism of microalgae in low atmospheric pressure. Experimental results and molecular dynamic simulations indicate that low atmospheric pressure reduces the density and enhances the fluidity of photosynthetic thylakoid membranes, leading to enhanced photochemical quenching. Particularly, extremely low pressure (<10 mbar) in a 100% CO2 atmosphere (Mars-like atmosphere) yields a photosynthetic efficiency comparable to that of Earth, shedding light on new astrobiological perspectives.

Soil salinity is a worldwide environmental constraint that affects crops growth and productivity. Silicon supply has been observed to ameliorate crops growth under various stresses. In this study, silicon supply was found to significantly enhance the decline the growth of sorghum-sudangrass (Sorghum bicolor × Sorghum sudanense) under salinity stress, increasing productivity and enhancing plants vigour throughout many aspects. Hence, silicon seems to be a promising approach to strengthen agriculture yield.

Understanding Mechanistic Basis of Plant Adaptation to Salinity and Drought

Drought and salinity are two major constraints in agriculture, restricting plant growth and yield in many parts of the world, especially in arid and semi-arid regions, and in the majority of plants, growth ceases under extreme exposure to drought and salt stress. This collection of Functional Plant Biology papers focuses on the advances and progress in studying the underlying mechanisms of salinity and drought tolerance in plants, particularly those that are considered agriculturally important.

Editor’s Choice – ‘Abiotic stress signalling and adaptation’

Agricultural crop production has to be increased by 70% by 2050 to ensure food security and meet the challenge of feeding a population of 9.3 billion. The only way to meet this challenge is by identifying key genes and mechanisms mediating plant sensing, signalling and adaptation to adverse environmental conditions, and then using modern genetic tools to modify them, to enable better plant performance. The papers selected for this Functional Plant Biology Collection contribute to this task and, therefore, may be of substantial interest to readers.
