Polyamines (PAs) metabolism and functions have started to raise attention from plant scientists in the last years. PAs have been investigated for their involvement in plant cell signaling and protection, proving that alterations in their endogenous levels can affect plant growth, development, and survival. The recognized roles of PAs in metal‐stressed plants are presented and discussed on a “case‐study”

Sunflower seeds (hybrid Luka) were primed with water (hydropriming) or sodium hydrosulfide (NaHS) solutions (0.1, 0.5, 1.0 and 1.5 mM NaHS) and subsequently dried to initial moisture content. Un‐primed (control) and primed seeds were germinated in a growth chamber on paper towels moistened with water or PEG 6000 solutions (2.5%, 5.0% and 10%), mimicking different drought stress levels. To evaluate

Little is known about the relationship between nutrition and the circadian clock in plants. The first global transcriptomic study in plants of the response to magnesium deficiency (‐Mg) revealed that the circadian clock was affected in the Arabidopsis thaliana model species. Interactions between the circadian clock and Mg status were here investigated in the light of recent knowledge. We highlight

A wide range of potentially plant pathogenic microorganisms are naturally present in the environment. Despite relying only on the innate immune system, plants are able to resist most of the pathogens. Plants employ a multi‐layered defense system in which the first layer triggers the basal resistance (PTI, PAMP‐triggered immunity). The second layer occurs when a resistance protein (R protein), that

Photoreceptors are primarily known as key photomorphogenic modulators of various physiological events during plant development. Although there are different groups of photoreceptors, the phytochrome B (phyB) family mediates developmental responses in a wide range of plant species, from seed germination to flowering. In addition, these molecules also regulate abiotic stress acclimation responses, such

“Interviews” is a new type of publication we are introducing in Annals of Applied Biology from 2019. The first one is with Prof. Simon Leather who has been on the board of Annals since 2005 as a Senior Editor and since 2015 as the Editor‐in‐Chief. We hope you enjoy reading this article and to know a bit more about Simon's research activities and his work as an Editor for Annals. Q: Tell us a bit about

Each year 25–75% of banana and plantain yields are lost because of rhizome damages caused by banana weevil (Cosmopolites sordidus) in growing regions of sub‐Saharan Africa. However, the specific plant defence response of the rhizome tissue in relation to the C. sordidus attack is unknown. Consequently, in this study, we evaluated whether plant defence substances in the rhizome are correlated with the

Carrot cultivation in Europe is suffering from infections with 'Candidatus Liberibacter solanacearum' (CLso), a psyllid‐transmitted bacterial pathogen. In this study field experiments were carried out in Finland to separately measure the effects of psyllid feeding damage and CLso infection on the carrot root growth and to reveal the dynamics of the spreading of CLso within the field. Most of the experiments
