AB  - According to the latest FAO report on the state of food security and nutrition in
the world (1), more than 720 million people faced hunger, and around 3 billion people
did not have access to a healthy diet. All these problematics, exacerbated by the current
COVID-19 crisis, led to an increase in the number of people affected by the so-called
hidden hunger, caused by an inadequate intake of essential micronutrients (MNs) such
as iron (Fe), zinc (Zn), selenium (Se) and provitamin A. Biofortification, intended as
the improvement of the nutritional quality of food crops through either conventional
breeding, agronomic practices ormodern biotechnologies, represents a sustainable, costeffective
and long-term approach to alleviate micronutrient-deficiency. Staple crops are
typically the major target of most biofortification studies, given their central role in
human diet. Wheat, specifically, contributes to around 20% of the total energy and
protein intake and to around 30% of the Fe and Zn intake worldwide. However, the
current level of MNs present in most wheat-derived food products is not enough to
meet the minimum daily intake, especially in the poorest regions of the world. For
these reasons, continuing to work on wheat biofortification is fundamental to ensure
the production of nutritious and sustainable food and to contribute to the reduction of
MNs deficiency.

AB  - The phytohormone auxin triggers transcriptional reprogramming through a well-characterized perception machinery in the nucleus. By contrast, mechanisms that underlie fast effects of auxin, such as the regulation of ion fluxes, rapid phosphorylation of proteins or auxin feedback on its transport, remain unclear1,2,3. Whether auxin-binding protein 1 (ABP1) is an auxin receptor has been a source of debate for decades1,4. Here we show that a fraction of Arabidopsis thaliana ABP1 is secreted and binds auxin specifically at an acidic pH that is typical of the apoplast. ABP1 and its plasma-membrane-localized partner, transmembrane kinase 1 (TMK1), are required for the auxin-induced ultrafast global phospho-response and for downstream processes that include the activation of H+-ATPase and accelerated cytoplasmic streaming. abp1 and tmk mutants cannot establish auxin-transporting channels and show defective auxin-induced vasculature formation and regeneration. An ABP1(M2X) variant that lacks the capacity to bind auxin is unable to complement these defects in abp1 mutants. These data indicate that ABP1 is the auxin receptor for TMK1-based cell-surface signalling, which mediates the global phospho-response and auxin canalization.
