The branching trait is influenced by various environmental signals, including the Red light:Far Red light (R:FR), an indicator of competition and an inhibitor of axillary bud growth. Branch development is influenced by an array of hormones, including auxin which indirectly suppresses bud growth as a consequence of auxin transport and signaling in the main stem. The suppressive effect of auxin sourced

γ-Aminobutyric Acid Participates in the Adult-Phase Adventitious Rooting Recalcitrance J. Plant Growth. Regul. (IF 2.672) Pub Date : 2020-10-25 Xu Li, Xiaozhao Xu, Fei Shen, Wei Li, Changpeng Qiu, Ting Wu, Yi Wang, Xuefeng Xu, Zhenhai Han, Xinzhong Zhang
In many tree species especially the rooting-recalcitrant woody perennials, the adventitious root (AR) in the juvenile phase can be easily induced by exogenous auxin, but AR formation becomes recalcitrant in the adult phase. Also, it is reported that the γ-aminobutyric acid (GABA) inhibits primary root growth in Arabidopsis and the AR formation in poplar (Populus ssp). So far, how GABA affects or is

Cowpea is a highly nutritious grain legume crop, cultivated mostly in a semi-arid environment and frequently confronts sporadic dry periods during different stages of plant growth, which drastically reduce its productivity. The current study was enacted to evaluate the biochar application and seed priming induced drought tolerance in cowpea. The seeds of cowpea were primed with CaCl2 (1% solution)

Burkholderia sp. Strain AU4i Promotes Arabidopsis Growth and Increases Plant Defence Response to Necrotrophic Pathogens J. Plant Growth. Regul. (IF 2.672) Pub Date : 2020-10-19 María Belén Colavolpe, Natalia Marina Villarreal, Silvia Estefanía Langer, Fernando Matías Romero, Gustavo Adolfo Martínez, Adesh Saini, Oscar Adolfo Ruiz, María Marina
Burkholderia sp. AU4i is a strain previously isolated from pea, which can act as plant growth-promoting rhizobacteria (PGPR). Here, we demonstrate that AU4i is able to promote Arabidopsis growth and increase the number of lateral roots as well as shoot and root dry weight. The inoculation of Arabidopsis leaves with AU4i significantly reduced the lesion’s areas provoked by the necrotrophic pathogens

Effects of Olive Mill Wastewater and Two Natural Extracts as Nitrification Inhibitors on Activity of Nitrifying Bacteria, Soil Nitrate Leaching Loss, and Nitrogen Metabolism of Celery ( Apium graveolens L.) J. Plant Growth. Regul. (IF 2.672) Pub Date : 2020-10-17 Catello Di Martino, Giuseppe Palumbo, Erika Di Iorio, Claudio Colombo, Thomas W. Crawford
Minimizing nitrification of fertilizer ammonium (NH4+) can reduce nitrate (NO3−) contamination of groundwater and increase nitrogen (N) use efficiency (NUE). Olive mill wastewater (OMW), hydroalcoholic extracts of Mentha piperita L. (Mp) and Artemisia annua L. (Aa), and synthetic nitrification inhibitor (NI) dicyandiamide (DCD) were investigated. All NIs reduced activity of nitrifying bacteria and

Effects of Shading by Bagging on Carotenoid Accumulation in Peach Fruit Flesh J. Plant Growth. Regul. (IF 2.672) Pub Date : 2020-10-16 Mingtao Zhu, Weichao Fang, Changwen Chen, Lirong Wang, Ke Cao
To clarify the effects of shading by bagging on the carotenoid accumulation in peach fruit flesh, the fruits of two yellow-fleshed peach cultivars (3D-8 and C18) were analyzed after a bagging treatment (yellow-black double-layered bag) at 50 days after full bloom. The bagging treatment significantly decreased the carotenoid content. The reason for this decrease may be that dark conditions due to bagging
