Rice feeds nearly half of the world population. Rice grains are rich in starch but low in micronutrients and bioactive compounds such as flavonoids. By contrast, tea leaves are rich in antioxidants such as catechins but low in calories. Zhu and colleagues combine the advantages of rice and tea by producing “tea rice”. They transformed […]
Phytohormones such salicylic acid (SA), ethylene (ET), and jasmonic acid (JA) are known to regulate plant immunity, but their spatial dynamics has remained unclear. Using a set of fluorescent reporters in Arabidopsis, Calabria et al. resolved the hormonal responses upon Fusarium oxysporum infection at single-cell level. The authors selected 75 immunity-related genes and used their […]
Microbial pesticides are widely applied to improve crop production, but the active molecules are largely unexplored. In a recent study, Mohamed et al., identified an antimicrobial peptide (AMP) from crop-associated microbes and showed its inhibitory effects on various phytopathogens. The authors first isolated bacterial strains from healthy crops and tested their antifungal activities. A Burkholderia […]
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 […]
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 […]
