Strigolactones are interesting phytohormones in their own right, but Luke Omoarelojie and colleagues say we should be looking at cross-talk with other hormones too.
Over Christmas, a couple of papers came out that suggest plants can respond to airborne sound waves. The findings challenge many ideas about how plants respond to sound.
Root cortical senescence (RCS) is a poorly understood phenomenon with implications for adaptation to edaphic stress. Schneider et al. demonstrate that ethylene modulates RCS.
Abscisic acid (ABA) is a well-studied phytohormone known to be involved in sub-sets of stress responses in plants, such as iron (Fe) deficiency and phosphorus (P) deficiency in Arabidopsis. However, whether ABA is...
Plant-growth-promoting bacteria (PGPB) are soil microorganisms able to interact with plants and stimulate their growth, positively affecting plant physiology and development. Ethylene is involved in plant development...
Strategies for protecting tomato plants against pathogens include treatment with synthetic chemicals or pathogen-derived compounds and transfer of resistance genes from wild species. Satkova et al. analysed expression...
Seeking to uncover the effects of ethylene on the metabolic process and pectin remobilising capacity of rice (Oryza sativa) that is grown in phosphorus (P)-deficient conditions, Zhu et al. find that ethylene positively...
Despite their importance in many aspects of plant physiology, information about the function of oxidative and, particularly, of nitrosative signalling in fruit biology is limited. Tanou et al. study the ripening of...
