Summary: Phytohormones are crucial in regulating plant growth, development, and stress responses globally. They play important roles in the transcriptional regulation of stress-responsive genes and metabolic adjustment. The balance between growth promotion and stress resistance is maintained through the coordinated action of phytohormones.

Summary: During eggplant microspore embryogenesis, the transition from embryos to calli instead of developing as true embryos is a bottleneck. Studies show that there are no genotype-specific endogenous GR profiles associated with a high embryogenic response. The role of GRs in the development of microspore-derived embryos in eggplant cultures is highlighted, with different GR accumulation patterns influencing the embryogenic response.

Summary: The use of plant growth regulators in horticultural crop production is common for improving produce quality and alleviating stresses. The indolamine compound melatonin (MEL) has emerged as a multifunctional molecule that regulates various aspects of growth and stress tolerance in solanaceous vegetable crops. It acts through reactive species signaling, hormonal cross-talk, and modulation of gene expression.

Summary: Auxins and cytokinins play crucial roles in regulating plant growth and development, with their interactions being complex and organ-specific. Gene expression is influenced by hormones and sucrose content, leading to functional clustering of genes from the same family. The study sheds new light on the crosstalk between auxin- and cytokinin signaling pathways.

Summary: Low-temperature stress has a significant negative impact on the growth and yield quality of fruit crops. While temperate fruit crops have developed mechanisms to tolerate low temperatures, tropical and sub-tropical fruit crops are more vulnerable to low-temperature stress. Fruit crops respond to low-temperature stress by activating stress-responsive genes, leading to changes in physiological, biochemical, and molecular mechanisms that enhance their tolerance and alleviate damage. However, the understanding of cold tolerance mechanisms is limited to a few fruit crops. Further research is needed to better understand the physiological, biochemical, and molecular components of cold tolerance in fruit crops.

Summary: Curly kale, known for its rich nutrition and health benefits, is highly sought after and considered one of the healthiest vegetables. However, conventional breeding methods for this vegetable take a long time to produce homozygous inbred lines. In this study, the isolated microspore culture (IMC) technique was successfully used to accelerate the breeding cycle of curly kale through efficient cytokinin thidiazuron (TDZ) treatment. The results showed that 0.2 mg/L TDZ had the optimal effect on embryo survival and plant regeneration, significantly shortening the breeding cycle.

Summary: Nitric oxide is a dynamic gaseous molecule that plays a key role in plant stress responses and signalling, with potential applications in engineering abiotic stress tolerance in crops. It can act as a signaling molecule at low concentrations but can also lead to oxidative stress and cellular damage at higher concentrations. Additionally, nitric oxide has been recognized as a potent stress alleviator and growth regulator in plants.

Summary: Reprogramming microspores development towards embryogenesis through stress treatment is crucial for doubled haploid production. This study investigates the epigenetic dynamics and expression of genes associated with histone post-translational modifications (PTMs) and microspore embryogenesis (ME) induction in bread wheat cultivars. The results reveal that the induction efficiency of ME is related to the epigenetic state and expression of genes involved in pollen development, auxin signaling, and hormone signaling pathways. This breakthrough study provides insights into the molecular mechanisms governing ME induction efficiency in recalcitrant wheat genotypes and other crops.

Summary: This article provides a summary of HSP70 post-translational control in plants, including the regulation of HSP70 expression and protein abundance by plant hormones, subcellular localization of HSP70s, chaperone activity, and their involvement in plant immunity against pathogens. The extensive regulation of HSP70 in plants has received little attention, and this review highlights the importance of HSP70 in plant defense mechanisms.

Summary: Embryogenic tissue (ET) is crucial for genetic modification and plant re-generation. This study induced ET from mature zygotic embryos in blue spruce and investigated the effects of different factors on ET proliferation and somatic embryo (SE) maturation. The specific concentrations of 2,4-D and BA during the ET proliferation stage significantly affected both ET growth and the quality of ET for SE maturation. Developing genotype-specific protocols is necessary for efficient production of mature SEs or somatic plants in blue spruce.

Summary: This study reports on the biochemical, cytochemical, and molecular studies on PR proteins and AGP during the early stages of androgenesis induction in rye breeding lines. The initiation of androgenesis was associated with high activity of beta-1,3-glucanases and chitinases, with some isoforms of beta-1,3-glucanases being anther-specific. Additionally, stress pre-treatments were found to promote AGP accumulation in the androgenesis-responsive rye line.

Summary: Microspore reprogramming towards embryogenic development is initiated by the genotype-specific threshold of reactive oxygen species accumulation, which requires an efficient antioxidative defence system for high effectiveness. The effectiveness of microspore embryogenesis is influenced by a complex network of internal and environmental factors, with a strong seasonal effect on microspore physiological status. Variations in response to ME-inducing stress tiller pre-treatment exist between different genotypes and cultivars, suggesting the importance of antioxidant molecules in influencing ME effectiveness.

Summary: Enhanced antioxidant defence is crucial for plant survival under stress conditions, but excessive activity can sometimes suppress the necessary signals for biological reactions. Microspore embryogenesis is triggered by stress in immature male gametophytes, with different stress treatments leading to genotype-specific defence responses in triticale and barley.

Summary: The study found that mannitol and n-butanol treatments led to fragmentation and stabilization of microtubules, promoting microspore embryogenesis in wheat. During the treatments, microspores exhibited complex MT reorganization, especially with the formation of MT aggregates in the perinuclear region, aiding in the induction of microspore embryogenesis.

Summary: Salt stress caused different responses in Arabidopsis thaliana mutants with altered tocopherol composition, with gamma-TC accumulating plants showing greater flexibility in regulating biocompound levels. Changes in tocopherol composition also affected xanthophyll cycle and metabolite levels under salt stress, suggesting distinct metabolic pathways regulated by alpha- and gamma-tocopherol.
