Despite cultivation in their native habitat, unpredictable and extreme weather events are applying pressure on the Australian macadamia industry to maintain the production of high-quality kernels. The industry has experienced losses in yield and quality due to shifts in the timing and volume of rain in recent years, and this has identified the requirement for transformational changes in orchard agronomic practices. Pre-harvest conditions that impinge on kernel oil content, kernel recovery, whole kernels and kernel appearance are discussed in this review. The impact of harvest and storage conditions on kernel quality are also reviewed. We propose opportunities for further research to optimise on-farm practices and to safeguard kernel quality post-harvest. This includes building on existing research to advance our understanding of the interaction of genetics with plant response to climate change. It also requires innovation to advance technologies that foster precision management, both spatially and temporally, in an environmentally sensitive manner.","PeriodicalId":12483,"journal":{"name":"Functional Plant Biology","volume":"52 ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143752010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigate the effects of methyl jasmonate (MeJA) and cold treatments on the expression of three specific miRNAs and the associated target genes in Baz spring wheat and Norstar winter wheat using qRT-PCR analysis. Our objective was to examine the impact of MeJA on vernalisation and cold adaptation in these genotypes. Results showed that MeJA had no significant impact on vernalisation and acclimation in Baz, while the compound decreased these traits in Norstar. Additionally, the expression of miRNAs in Norstar was significantly reduced after a 2-day cold treatment, particularly for miR156 and further reduced after 14days for miR172 and miR319 . In contrast, Baz showed varied gene expression responses, with an increase in miRNA levels after the 14-day cold treatment. MeJA combined with a 2-day cold treatment suppressed the expression of SPL , AP2 and MYB3 target genes, with the most pronounced suppression observed in SPL . However, AP2 was induced after 14-day cold treatment in both cultivars. The study highlighted an inverse relationship between miRNAs and target genes under vernalisation conditions, underscoring the complex regulatory interactions between genotype, miRNAs and the associated target genes. Therefore, these findings provide new insights into how MeJA and cold treatments modulate miRNA and gene expression, enhancing our understanding of wheat's adaptive response mechanisms.","PeriodicalId":12483,"journal":{"name":"Functional Plant Biology","volume":"52 ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143729406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study experimentally investigated the role of druses in Atriplex lampa under drought and herbivory treatments. We propose that both stressors trigger druse synthesis. Furthermore, if druse production is an adaptation to stress, the allocation of resources to other physiological functions should not be affected. These hypotheses were experimentally tested under greenhouse and natural field conditions. Leaves of A. lampa were collected from eight rangelands in Monte Desert in Argentina, which shared similar environmental characteristics but differed in stocking rates. The manipulative experiment in the greenhouse consisted in applying drought and herbivory treatments to A. lampa seedlings. The highest druse abundance was observed at intermediate stocking rates, suggesting resource limitation for druse synthesis at extreme stocking rates. The adaptive advantage of druse synthesis was evident only for drought stress treatment, where higher druse abundance was correlated with improved growth rates. When both stressors were combined, there was no difference in druse abundance with respect to control treatment, indicating that herbivory negatively influenced the adaptive response to drought. Druse synthesis is an adaptation to drought that is susceptible to herbivory stress.","PeriodicalId":12483,"journal":{"name":"Functional Plant Biology","volume":"52 ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143523182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plants were exposed to prolonged heat stress under high and low air humidity. Both species decreased non-photochemical quenching at 37-42°C, which increased at 46°C. A decrease of photosystem II activity at 46°C in lower air humidity was achieved through different mechanisms. In barley, photosystem II was downregulated by the increase of non-photochemical quenching. In maize, photosystem II was downregulated by the increase of acceptor-side limitation. Analysis of transients also revealed differences between species. One second after a light induction, limitations flashes at the acceptor sides of both photosystems. Elevating the temperature decreased these flashes; acceptor-side limitations of both photosystems decreased proportional to each other. In maize, the size of flashes slightly diminished at 37°C and decreased more at 42-46°C. In barley, the size of flashes greatly decreased at 37°C and gradually returned to the control level under higher temperatures. Around photosystem II, the flash was quenched by a burst of non-photochemical quenching.

This has led to interest in identifying alternative and renewable energy sources such as biofuel generation from photosynthetic organisms. A wide variety of prokaryotic and eukaryotic microorganisms, known as microalgae, have the potential to be economical and ecologically sustainable in the manufacture of biofuels such as bio-hydrogen, biodiesel, bio-oils, and bio-syngas. By using contemporary bioengineering techniques, the innate potential of algae to produce biomass of superior quality may be enhanced. In algal biotechnology, directed genome modification via RNA-guided endonucleases is a new approach. CRISPR/Cas systems have recently been frequently used to modify the genetic makeup of several aquatic and freshwater microalgae. The majority of research has used the Cas9-driven Type II system, one of two classes and six unique kinds of CRISPR systems, to specifically target desired genes in algae, and knock them out and down, or both. Using CRISPR technology to modify its genetic makeup, microalgae has produced more biomass and increased in lipid content. This review highlights the attempts made so far to target microalgae genome modification, discusses the prospects for developing the CRISPR platform for large-scale genome modification of microalgae, and identifies the opportunities and challenges in the development and distribution of CRISPR/Cas9 components.","PeriodicalId":12483,"journal":{"name":"Functional Plant Biology","volume":"52 ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143398862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To identify informative models related to stress conditions, we constructed meta-analysis and two distinct weighted gene co-expression networks. We then performed module trait association analyses. Additionally, we conducted functional enrichment analysis of significant modules to shed light on the biological performance of underlying genes in the two contrasting stresses. In the next step, we inferred the gene regulatory networks between top hub genes of significant modules, kinases, and transcription factors (TFs) using a machine learning algorithm. Our results showed that at power=10, the scale-free topology fitting index (R2) was higher than 0.8 and the connectivity mean became stable. We identified 31 co-expressed gene modules in barley, with 13 and 14 modules demonstrating significant associations with drought and waterlogging stress, respectively. Functional enrichment analysis indicated that these stress-responsive modules are involved in critical processes, including ADP-rybosylation factors (ARF) protein signal transduction, ethylene-induced autophagy, and phosphoric ester hydrolase activity. Specific TFs and kinases, such as C2C2-GATA, HB-BELL, and MADS-MIKC, were identified as key regulators under these stress conditions. Furthermore, certain TFs and kinases established unique connections with hub genes in response to waterlogging and drought conditions. These findings enhance our understanding of the molecular networks that modulate barley's response to drought and waterlogging stresses, offering insights into the regulatory mechanisms essential for stress adaptation.","PeriodicalId":12483,"journal":{"name":"Functional Plant Biology","volume":"52 ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143440563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
