Seed germination is a crucial phase where a plant embryo transitions from dormancy to active growth, emerging as a seedling. This intricate process is highly susceptible to environmental cues, particularly abiotic stress factors including drought, salinity, and temperature extremes, which can profou...

SOM encodes a nucleus-localized CCCH-type zinc finger protein and negatively regulates seed germination in Arabidopsis thaliana. We have previously demonstrated that ectopic expression of SIABI3, an important transcription factor in abscisic acid (ABA) signaling pathway, resulted in alteration of SI...

Fruit wounding occurred at harvest and transportation requires rapid suberization as a major part of the healing process to prevent infection and desiccation. The focus of this work was to explore the mediation of abscisic acid (ABA) on wound-induced suberization and to determine expression profiles...

Pyrabactin resistance 1-like proteins (PYLs) are direct receptors of abscisic acid (ABA). For the redundant and polymorphic functions, some members of the PYL family interact with components of other signaling pathways. Here, 253 positive colonies from a maize cDNA library were screened as interacti...

ABSTRACT Drought has been identified as one of the important environmental factors in the context of climate change due to its interaction with other biotic and abiotic stresses. However, only a few studies have reported the effect of breeding on forest adaptability to climate change. Using a common...

Drought is a multifaceted stress condition that inhibits crop growth. Seed germination is one of the critical and sensitive stages of plants, and its process is inhibited or even entirely prevented by drought. Polyamines (PAs) are closely associated with plant resistance to drought stress and seed g...

Seed dormancy is one of the key challenges in the development of foxtail millet (Setaria italica L. Beauv.). This study explored the use of ultra-fine bubbles water (UFBW) and plasma-activated water (PAW) to break seed dormancy in foxtail millet by first identifying the causes of dormancy and then...

Drought stress is an abiotic stress that imposes serious constraints on plants. The present investigation was carried out to determine the inter-relationship between some physiological attributes of soybeans affected by drought stress and pure isolates of Azotobacter and Azospirillum. Drought stress...

Halophyte plants, with genes responsive to abiotic stress, are promising candidates to enhance crop stress tolerance, but reliable RT-qPCR analysis requires the precise selection of candidate reference genes (CRGs) due to their inconsistent expression across tissues and stress conditions. In this st...

Understanding seasonal interactions among hydraulic, chemical and molecular signalling under water deficit is crucial for improving vineyard irrigation strategies under climate change and increasing water scarcity. We aimed to test how irrigation strategies and phenology affect the hydraulic adjustm...

Drought stress is a devastating natural stress that threatens crop productivity and quality. Mitigating the adverse effects of drought stress on wheat is a key object in agriculture. C-repeat binding transcription factor/DROUGHT RESPONSE ELEMENT BINDING FACTOR 1 (CBF/DREB1) transcription factors are...

Subsequent to the harvesting of ‘Red Zaosu’ pears, a swift decline in quality becomes evident. This is characterized by the discoloration of the peel, the softening of the flesh and metabolic alterations during storage. To elucidate the regulatory roles of phytohormone in fruit preservation, posthar...

Rice is the world’s largest food crop, but it often encounters flowering asynchronization problems during hybrid rice seed production. In addition, the slow closure of female florets leads to seed mildew and affects the quality. The hormone abscisic acid (ABA) plays a crucial role in plant responses...

Gaining high yield of potato is very crucial for farmer and quality also has a great impact on their production. Beside the quality and yield using the amount of irrigation also important to reduce water lose. The tuber yield and quality of potato (Solanum tuberosum L.) is impacted by irrigated wate...

Relevance. In modern climatic conditions, the suppression of production process occurs against the background of short-term or long-term exposure to unfavorable environmental factors on agricultural plants, and, therefore, yield decreases. In this regard, there is a need for the use of growth regula...

The regulation of stomatal movements is crucial for plants to optimize gas exchange and water balance. The plant hormone abscisic acid (ABA) triggers stomatal closure in response to drought, effectively minimizing water loss to prevent hydraulic failure. However, it significantly constrains photosyn...

The use of technologies in greenhouse vegetable growing that ensure environmental safety, high plant productivity is an important component. In this regard, the issues of hormonal regulation of the processes of fruit set, their growth, and the causes of abscission are topical. The synthesis of auxin...

Granule size distribution of wheat starch is an important characteristic that can affect its chemical composition and the functionality of wheat products. Two high-yield winter wheat cultivars were used to evaluate the effects of the application of exogenous ABA or GA during the reproductive phase o...
