Summary Lignin is a major component of plant cell walls and conserved basic defense mechanism in higher plants deposited response to aphid infection. However, the molecular mechanisms lignin biosynthesis infection effect on feeding behavior remain unclear. We report that 4‐Coumarate:coenzyme A ligase 2 ( Cm4CL2 ), gene encoding key enzyme pathway, induced by feeding, resulting deposition reduced attack. Upstream regulator analysis showed expression was directly upregulated CmMYB15‐like, an SG2‐type R2R3‐MYB transcription factor. CmMYB15‐like binds AC cis ‐element promoter region . Genetic validation demonstrated contributed wall thickening, which consequently enhanced resistance ‐dependent manner. This study first show CmMYB15‐like‐Cm4CL2 module regulates feeding.

Abstract Salinity is a major environmental constraint that substantially limits global agricultural productivity. HD‐Zip I transcription factors are involved in plant responses to salt stress, but little known about the genes apple ( Malus domestica ). Here, we characterized function of an gene MdHB7‐like ) and report its expression induced by stress. To further explore role created overexpressing RNAi transgenic plants. The overexpression improved photosynthetic performance reduced ROS Na + accumulation under Plants overexpressed also showed increased proline soluble sugars, which may have played important their stress tolerance. suppression had opposite effects. Together, our results demonstrate regulator tolerance apple. Our provide new insights for future research on mechanisms promotes potential target molecular breeding

Abstract Flowering time is known to be regulated by numerous pathways, such as the autonomous, gibberellin, aging, photoperiod-mediated, and vernalization pathways. These regulatory mechanisms involve both environmental triggers endogenous hormonal cues. Additional flowering control mediated other phytohormones, auxin, are less well understood. We found that in cultivated strawberry ( Fragaria × ananassa ), expression of auxin response factor4 FaARF4 ) was higher stage than vegetative stage. Overexpression Arabidopsis thaliana woodland vesca resulted transgenic plants earlier plants. In addition, FveARF4 -silenced showed delayed compared plants, indicating function similarly regulating flowering. Further studies ARF4 can bind promoters floral meristem identity genes APETALA1 AP1 FRUITFULL FUL inducing their and, consequently, strawberry. Our reveal an auxin-mediated pathway involving induction expression.

Abstract Low temperatures severely restrict melon seedling growth. However, the mechanisms by which adapts to cold stress are poorly understood. Arginine decarboxylase (ADC), a key synthetase, catalyzes putrescine biosynthesis in plants. In this study, we found that CmADC functions as positive regulator of tolerance. addition, two transcription factors, abscisic acid-responsive element (ABRE)-binding factor 1 (CmABF1) and C-repeat binding 4 (CmCBF4), directly target trigger its expression. Consistently, virus-induced gene silencing (VIGS) CmABF1 or CmCBF4 downregulated abundance, decreased accumulation, reduced Furthermore, some other CBF ABF members show at least partial functional redundancy complementarity with CmCBF4. Overall, our work reveals ABA, CBF, polyamine pathways may form cooperative regulatory network participate plant response.
