Summary: Plants undergo various environmental stresses that affect their growth and survival. They respond to these stresses by inducing changes at morpho-physiological, biochemical, molecular, and genetic level. One of the important changes is the production of phytomelatonin, a signaling molecule that helps plants tolerate stress by delaying senescence, reducing inhibition of photosynthesis, and improving antioxidant status. Studies have shown the positive effects of exogenously applied phytomelatonin on seed germination, plant growth, yield, and chlorophyll content. This review highlights the potential of phytomelatonin in plants and its mechanism of action in stress alleviation, as well as its interaction with other signaling molecules.

Summary: Duckweeds are small aquatic higher plants that grow on or just below the surface of still waters. Despite their small size, they are able to survive and reproduce in various climate zones around the world. They face multiple challenges, including high temperatures, light intensity fluctuations, nutrient shortage, damage by microorganisms and herbivores, presence of harmful substances, competition from other plants, winter cold, and drought. Duckweeds have adapted mechanisms for rapid growth, organ formation, and clonal diversity to cope with these challenges. They can also cooperate with other organisms in their environment to improve their chances of survival.

Summary: Food security relies on plant productivity and resilience to climate change, which can be enhanced by silicon's regulation of various mechanisms in plants. Silicon aids in improving plant growth productivity, alleviating biotic and abiotic stress conditions, and plays a role in osmotic adjustment, metabolic processes, and phytohormones. Further research on silicon transporters and regulatory genes is needed for better understanding and application in different stress conditions.

Summary: By using bioinformatics methods, this study discovered 226 walnut R2R3-MYB genes at the genome level and classified them into 23 subgroups based on evolutionary relationships. These genes were unequally distributed across 16 walnut chromosomes and exhibited similar gene structure and conserved motifs within the same subgroup. Tandem and segmental duplications contributed to the amplification of R2R3-MYB genes in walnut. The walnut R2R3-MYB genes showed homology to Populus trichocarpa, Arabidopsis thaliana, and Zea mays genes. The expression of these genes was induced after infection with Colletotrichum gloeosporioides and various abiotic stress treatments, suggesting their involvement in stress response. Co-expression studies indicated a potential role of walnut R2R3-MYB genes in the ICE1-CBF pathway of cold signal transduction.

Summary: This article discusses the central role of organic acids (OAs) in cellular metabolism, highlighting their importance in plant stress responses, soil carbon sequestration, and sustainable food production. OAs are versatile in plant stress tolerance and efficient chelating agents, with key functions in combating climate change. The multiple functions of OAs, such as modifying pH and binding metals, are crucial factors in understanding their important roles in plant stress biology.

Summary: DELLA proteins participate in ovule initiation by forming a protein complex with the CUC2 transcription factor. This interaction helps determine the boundary regions between ovules during pistil development. DELLA proteins may also act as transcriptional co-regulators in a CUC2-dependent manner at certain gene loci.

Summary: The gene underlying the melon fruit shape QTL fsqs8.1 belongs to the Ovate Family Proteins, and changes in gene expression likely due to a cryptic structural variation at this locus lead to variation in fruit morphology. The round fruit shape induced by the CALC allele at the early ovary development stage is a result of this variation, which is responsible for transgressive segregation in fruit shape.

Summary: In this study, a combination of mutated acetolactate synthase (ALS) gene and herbicide selection agent imazapyr (IMZ) was used to efficiently recover transgenic citrus plants. The approach allowed the development of cisgenic regenerants and the generation of edited, non-transgenic plants with IMZ resistance. It was found that transient expression of the ALS gene induced mutations and resulted in IMZ-resistant shoots at a frequency of 11.7%.

Summary: Huanglongbing (HLB), the most destructive citrus disease, is associated with the Candidatus Liberibacter species Ca. L. asiaticus (Las). In this study, it was found that certain Oceanian citrus genotypes and hybrids showed full resistance to Las, with their leaves remaining Las-free even when the susceptible rootstock was infected. However, Las was detected in the stem bark above the graft union. Further experiments confirmed that the insects feeding on the Oceanian citrus plants and their canopies, new flushes, and leaves from rooted cuttings remained negative for Las, and their budwood pieces were unable to infect sweet orange through grafting.

Summary: Seed size is a crucial factor in crop breeding. A study has found that DELLA proteins play a key role in controlling seed size by regulating the transcriptional activation of AINTEGUMENTA, which promotes cell proliferation and organ growth in the ovule integuments. This discovery suggests that modulation of the DELLA-dependent pathway could be a potential approach to improve crop yield.
