Summary: In this study, 10 PavNCED genes were identified in the sweet cherry genome and were found to be related to hormone regulation, stress responses, and plant development. Transcription factors such as ERF, bHLH, and TCP were identified to be involved in the regulation of PavNCED genes. Expression pattern analysis showed that PavNCED1-5 genes were highly expressed during flower bud dormancy, and the expression of PavNCED5 decreased with the decline of ABA content in sweet cherry. Overexpression of PavNCED5 in Arabidopsis resulted in dormancy deficiency of seeds.

Summary: In this study, 23 CCD genes were identified from the Populus trichocarpa genome and their expression patterns were analyzed. The results showed that these genes displayed different tissue-specific expression patterns and were responsive to osmotic stress. The genome-wide identification of CCD genes provides a foundation for further investigating the regulation mechanism of osmotic stress and molecular breeding of poplar.

Summary: High temperature inhibits the accumulation of anthocyanin in sweet cherry fruit peel and slows down the coloring process. It also affects the levels of sugars and plant hormones. ABA may be a key regulator in the high-temperature-inhibited fruit coloring of sweet cherry.

Summary: This study compares three sequential phenology models for the sweet cherry cultivar 'Summit' and finds that the inclusion of ABA-related heat weighting significantly improves the performance of the model. The results highlight the importance of considering factors such as bud ABA content for accurate physiological modeling.

Summary: This study identified the WRKY transcription factor GhWRKY1-like as a positive regulator of drought tolerance in Arabidopsis by manipulating ABA biosynthesis. GhWRKY1-like can interact with promoters of key enzymes involved in ABA biosynthesis and promote their expression, enhancing drought tolerance in plants.

Summary: This study identified a set of transcription factors that are essential for abscisic acid (ABA)-promoted fruit softening in sweet cherry. The study revealed that ABA regulates the activity of cell wall-modifying enzymes by directly controlling the expression of transcription factors. Furthermore, it was found that ABA can repress the expression of an auxin response factor, which in turn activates the expression of the transcription factors. This study provides insights into the physiological framework of fruit softening and establishes a direct functional link between ABA, transcription factors, and cell-wall-modifying genes in mediating fruit softening.

Summary: In this study, it was found that light exposure induces anthocyanin accumulation and ABA production in bicolored sweet cherry fruit. Two B-box genes, PavBBX6 and PavBBX9, were identified as positive regulators of ABA biosynthesis and red coloration in the fruit.

Summary: The study suggests that abscisic acid (ABA) signaling plays a role in the ripening of raspberry fruit, as evidenced by the concomitant increase in ABA content and the expression of ABA biosynthesis and receptor-related genes during fruit development.

Summary: This study identified and functionally characterized PavNAC56, a NAC transcription factor that positively regulates the ripening and softening of sweet cherry fruit. The results showed that PavNAC56 is specifically and abundantly expressed in the fruit and its expression is regulated by abscisic acid. Further experiments revealed that PavNAC56 directly binds to the promoters of several genes related to cell wall metabolism and activates their expression, thereby controlling fruit ripening and softening.

Summary: Fruits play a crucial role in providing vitamins, minerals, and nutrients in the human diet. They also contain compounds that have important nutraceutical properties, including antioxidant and anti-inflammatory effects. Cherries, in particular, are high in bioactive compounds and minerals, and their consumption contributes positively to health.

Summary: The chloride component of NaCl salinity leads to transient alkalinization of the leaf apoplast, which initiates stomatal closure by affecting the pH(apo) and subsequently the transcription of ABA, independently from other chloride stress-induced effects.
