FP24277Assessing the synergistic effects of biochar, hydrogel and biofertilizer on growth and physiological traits of wheat in saline environments

Dilfuza Jabborova, Zafarjon Jabbarov, Tokhtasin Abdrakhmanov, Orzubek Fayzullaev, Baljeet Singh Saharan, Kahkashan Perveen, Syed Muhammad Zaka, Andrea Mastinu and Riyaz Sayyed 0000-0002-1553-1213
 

Excess amounts of salts used in agriculture lead to deterioration of crop growth and yield. This problem requires urgent, sustainable resolution. The use of soil microorganisms not only reduces salt levels but helps plants to grow under such stress. Our study revealed that applying soil microorganisms significantly improved the growth and yield of wheat under salt stress, and also enhanced soil fertility.

Shading significantly reduces grain size, 1000-grain weight, starch content, and enzyme activities in the grain development of wheat (Triticum aestivum). Phenotypic and transcriptome analyses of wheat cv. ZY96-3 under normal and shaded conditions revealed shading strong effect on grain-filling rates and starch metabolism. Transcriptomic results identified altered pathways, including photosynthetic antenna proteins, carbon fixation, and starch metabolism. Key genes (e.g. PetC, Fd, LFNR1) were linked to electron transport. These findings provide insights into breeding wheat with high photosynthetic efficiency for low-light regions.

Drought is the most common unfavorable environmental factor leading to a significant decrease in plant productivity. The use of lectins makes it possible to increase the resistance of plants to water deficiency by influencing the metabolism of the plant cell. Thus, the use of lectins can provide an affordable and simple solution to increase the productivity of the crop in conditions of limited water availability.

FP24338Counting modes of acyl-lipid desaturases

Alexander Y. Starikov, Roman A. Sidorov and Dmitry A. Los 0000-0002-0142-7853
 

Fatty acid desaturases (FADs) dehydrogenate C–C bonds in fatty acids, resulting in unsaturated C=C bonds. FADs are highly specific to acyl substrates, as well as the position and geometry of the newly added cis double bonds. Δ9-FADs were shown to be carboxyl-specific. Δ12(ω6)-FADs count three carbons toward the methyl end (x + 3) from an existing double bond in monoene precursors. Δ6- and Δ15(ω3)-FADs count from the carboxyl terminus.

FP24343Do cyanogenic glucosides help sorghum manage a fluctuating nitrogen supply?

Bethany English, Alicia A. Quinn, Charles R. Warren, Roslyn M. Gleadow 0000-0003-4756-0411 and Harry Myrans 0000-0003-2690-6188
 

There is an emerging hypothesis that, alongside defence, cyanogenic glucosides may help plants manage nitrogen. We compared the growth and nitrogen partitioning of a cyanogenic glucoside-free mutant sorghum line to the wildtype under two treatments, in which nitrogen supply fluctuated at different rates. Unexpectedly, cyanogenic glucosides did not confer a growth advantage in sorghum but there was evidence of rapid recycling in young plants during nitrogen deficiency, demonstrating the dual purpose of dhurrin in defence and nitrogen storage.

This study investigated the impact of methyl jasmonate (MeJA) on alternative splicing in Catharanthus roseus using RNA-Seq. We identified differentially expressed alternatively spliced genes and co-expressed splicing factors (SFs) in response to MeJA treatment. Findings suggest that MeJA activates SFs, leading to specific mRNA isoforms that enhance the plant’s ability to respond to environmental and developmental signals. This work provides insights into the complex regulatory mechanisms underlying adaptive responses of C. roseus.

FP24218Challenges to optimal macadamia (Macadamia spp.) kernel quality in a changing climate

Suzy Y. Rogiers 0000-0001-6637-3561, Kevin P. Quinlan and Jeremy D. Bright
 

The macadamia (Macadamia spp.) is an Australian native, and its nuts are a delicious source of nutrition with many health benefits. Extreme weather over the last decade has hampered the industry through yield losses and inferior quality kernels. Changes in environmentally sustainable orchard management practices are proposed to improve tree resilience and the production of first grade kernels.

Physiological and biochemical changes in wheat during cold acclimation and vernalisation are pivotal for winter survival. We examined methyl-jasmonate (MeJA) and cold treatment effects on miRNA regulation and target genes in Baz spring wheat and Norstar winter wheat. MeJA’s impact on vernalisation and acclimation varied between cultivars, with Norstar experiencing decreased traits and Baz showing minimal effects. Results underscored the intricate interplay between genotypes, miRNAs and target genes under different vernalisation treatments, elucidating the response of wheat to MeJA and cold treatments.

FP25010The role of nuclear factor-Y (NF-Y) transcription factor in plant growth and development

Jiayi Hong, Xiaofeng Feng, Yongping Cai, Muhammad Aamir Manzoor 0000-0002-4277-5483 and Yunpeng Cao 0000-0001-5976-2382
 

NF-Y is a key transcription factor found in plants, animals, and fungi, with higher plants having more NF-Y subunits. It consists of three parts (NF-YA, NF-YB, and NF-YC) that work together to regulate gene activity by binding to DNA or interacting with other proteins. NF-Y plays a vital role in plant growth and development. Understanding its structure and function can help improve crops and support sustainable agriculture.

FP24294NtDHS regulates leaf senescence by modulating gene translation in Nicotiana tabacum

Junping Gao, Ying Wang, Xinxi He, Long Chen, Shuaibin Wang, Xinyao Zhang, Sirui Zhu, Xiaoxu Li, Xiaonian Yang, Wenxuan Pu and Yuanyuan Li 0009-0000-1196-3863
 

Leaf senescence and plant growth are crucial for crop health and yield. This study shows that the NtDHS–NteIF5A complex in Nicotiana tabacum regulates these processes by controlling the translation of genes involved in chlorophyll metabolism and cell growth. The discovery of this translational regulation provides new insights into plant biology, offering potential strategies for improving crop performance by manipulating the balance between growth and aging in plants.

FP24299Drought resistance or herbivory defense strategy? Oxalate druses function in a forage xeric species

D. F. Jaume 0009-0007-0303-1127, Y. I. Pelliza, A. Nanni and M. Tadey
 

Our study determined that druse synthesis in a xerophytic plant species constitutes an adaptation to drought, not to herbivory. Under drought stress conditions, higher druse abundance correlated with increased growth rates. In contrast, the presence of herbivory did not induce druse synthesis, and its presence influenced the response to drought stress. Our findings highlight the role of druses in the adaptive response to drought and reveal how interactions with other common stressors, such as herbivory, can modify this response.

FP24292Effects of selenium on leaf traits and photosynthetic characteristics of eggplant

Lu Zhang, Xiawei Zhao, Yan Wang, Xinyu Ma, Haolin Li and Chengzhang Zhao 0000-0002-8610-6599
 

Semi-arid regions have abundant light and heat, concentrating agricultural activities. However, high temperatures and drought conditions pose significant constraints on crop productivity. Our study found that an optimal Se application enhanced the acquisition traits in eggplants, thereby maximising photosynthetic gains and achieving a ‘high input – rapid return’ model in terms of leaf construction costs and photosynthetic efficiency. Our findings suggest that Se application can serve as a crucial strategy to enhance crop productivity in semi-arid environments.

FP24241Effect of increased air temperature and vapour pressure deficit on water relations, gas exchange, and stem increment in saplings of Norway spruce (Picea abies)

Gristin Rohula-Okunev 0000-0002-8629-3160, Priit Kupper 0000-0002-1243-3511, Arvo Tullus, Mai Kukumägi, Marili Sell and Ivika Ostonen
 

Although the rise in temperature has been intensively studied, the associated effect of air humidity and vapour pressure deficit (VPD) on trees must be clarified. We investigated the impact of these factors on Norway spruce (Picea abies) saplings and discovered that the higher temperature alone does not affect trees, while the interaction with VPD rise improved tree functioning. These findings suggest that aside from temperature, the impact of air humidity should be considered by predicting trees’ response to global warming.

The existence of C3- and C4-types of photosynthesis enables plant to better adapt to different environment conditions including diverse temperature regimes. The current study revealed differences between C3-plant barley and C4-plant maize in mechanisms limiting activity of photosystems I and II. These results increased the biophysical component that is underrepresented in the general understanding of distinctions between C3- and C4-types of photosynthesis.

We applied a systems biology approach to gain a deep insight into the regulatory mechanisms of barley (Hordeum vulgare) under drought and waterlogging stress conditions. The identified gene modules, enriched pathways, and regulatory networks provide valuable insights into the complex molecular responses of barley to drought and waterlogging stresses. This comprehensive analysis significantly contributes to our understanding of the genetic and regulatory mechanisms underlying stress responses in barley.

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.
