Abstract As critical signalling molecules, both gibberellin (GA) and auxin play essential roles in regulating root elongation, and many studies have been shown that auxin influences GA biosynthesis and signalling. However, the mechanism by which GA affects auxin in root elongation is still unknown. In this study, root elongation and DR5-GUS activity were analyzed in rice seedlings. Paclobutrazol-induced short root phenotypes could be partially reversed by co-treatment with IAA, and the inhibitio...

Abstract Sugars are the key regulatory molecules that impact diverse biological processes in plants. Hexokinase, the key rate-limiting enzyme in hexose metabolism, takes part in the first step of glycolytic pathway. Acting as a sensor that mediates sugar regulation, hexokinase has been proved to play significant roles in regulating plant growth and development. Here, we isolated a hexokinase gene SlHXK1 from tomato. Its transcript levels were higher in flowers and leaves than in other organs and...

Abstract Jasmonate (JA) signaling is a key mediator of plant development and defense which arose during plants transition from an aqueous to terrestrial environment. Elucidating the evolution of JA signaling is important for understanding plant development, defense, and production of specialized metabolites. The lineage of key protein domains characterizing JA signaling factors was traced to identify the origins of CORONITINE INSENSITIVE 1 (COI1), JASMONATE ZIM-DOMAIN (JAZ), NOVEL INTERACTOR OF ...

Abstract Flower formation is a basic condition for fruit set in all flowering plants. The normal stamen of tomato flower fused together to form a yellow cylinder surrounding the carpels. In this study, we identified an un-fused flower (uf) tomato mutant that is defective in petal, carpal and stamen fusion and lateral outgrowth. After RNA-seq-based BSA (BSR), the candidate region location was identified in the long arm of chromosome 3. Using map-based cloning with InDel and CAPS markers, the UF c...

Abstract Here, we describe functional characterization of Arabidopsis thaliana MYB4 transcription factor, a member of R2R3-subfamily of MYB domain protein, in the regulation of Cd-stress tolerance in Arabidopsis. Transgenic Arabidopsis plants overexpressing MYB4 showed appreciable Cd tolerance than wild-type plants, while MYB4 loss of function mutant lines (atmyb4) showed increased sensitivity to Cd-stress. MYB4 overexpression lines showed strong activation of anti-oxidant defense components and...

Abstract Using classical breeding, plant breeders envision a plant type whose yield they aim to enhance by selecting for individual traits to create model/ideal plants or ideotypes. To achieve this, those factors restricting yield need to be identified and controlled through the use of new technologies to achieve the desired ideotype. This study aimed to determine the ideotype of seven genetically modified (GM) and non-GM rice (Oryza sativa L.) cultivars. Field experiments were carried out in th...

Abstract To elucidate the mechanisms of salt acclimation, physiological parameters of 70 rice varieties were compared under control and salt stress conditions after the acclimation treatment. The results indicated that some rice varieties had the ability to acclimatize to salt stress, exhibiting improved growth following the acclimation treatment under subsequent salinity stress compared to those without acclimation treatment. Conversely, some varieties exhibited reduced growth both with and wit...

Abstract Spring droughts are expected to become more frequent in Central Europe as a result of climate change. Their coincidence with flowering of biennial crops like winter oilseed rape (Brassica napus) can cause major impact for yield development. However, no data is available on the diversity of genetic regulation of drought tolerance during this stage under realistic conditions. Here, we assessed the phenotypic plasticity of drought response for eight diverse B. napus accessions under field-...

Abstract Ambient temperature has profound impacts on almost every aspect of plant growth and development, including seed germination, stem and petiole elongation, leaf movement, stomata development, flowering, and pathogen defense. Although the signal transduction pathways underlying plant responses to extreme cold and heat temperatures have been well studied, our understanding, at the molecular level, of how plants adjust phenotypic plasticity in response to nonstressful ambient temperature is ...

Abstract The anthocyanin biosynthetic pathway regulated by exogenous and endogenous factors through sophisticated networks has been extensively studied in kiwifruit (Actinidia arguta). However, the role of micro RNAs (miRNAs) as regulatory factor in this process is largely unclear. Here, we demonstrate that miR858 is a negative regulator of anthocyanin biosynthesis by repressing the target gene AaMYBC1 in red-colored kiwifruit. Transient co-transformation in Nicotiana benthamiana confirmed that ...
