 Apoplastic pH acts as a chemical switch in plants by modulating H2O2 redox potential

/in /by

Environmental stimuli, such as drought and salinity, alter cellular conditions including apoplastic pH (pHApo) in plants. These stimuli often lead to an elevation in pHApo which is closely associated with cell functions and plant growth. However, the mechanism behind is largely unexplored. A recent study suggests that pHApo acts as a chemical switch, regulating signalling […]

Double attack! Herbivore insects feed on plants and silence their genes

/in /by

In the natural environment, plants are constantly attacked by animals. Plant immunity is regulated by a network of genes and hormones including salicylic acid (SA) and jasmonic acid (JA). A recent study suggests that herbivore insects threaten plants with concerns more than the bite. Han et al., found that the phloem-feeding whitefly (Bemisa tabaci) transfers […]
