The traditional method for the identification of AS is semi-quantitative RT-PCR, which is easy to perform (Palusa <i>et al</i>., <span>2007</span>; Li <i>et al</i>., <span>2020</span>; Riegler <i>et al</i>., <span>2021</span>; Han <i>et al</i>., <span>2022</span>).

RT-qPCR enables real-time monitoring of changes in the fluorescence signal, quantification of differences between expression levels, and simultaneous detection of multiple in a single reaction. According to the copy number of different isoforms, isoform expression patterns can be identified by combining with absolute quantitative techniques.

This is because iron is a co-factor for several metalloproteins involved in essential physiological processes such as respiration in mitochondria or photosynthesis in chloroplasts. In most soils, iron is present in the form of insoluble oxides/hydroxides rendering it poorly available to plants. To cope with this poor bioavailability, plants have evolved sophisticated strategies to take up iron from soils (Berger <i>et al</i>., <span>2023</span>; Li <i>et al</i>., <span>2023</span>). Arabidopsis plants preferentially use the reduction-based strategy (the so-called Strategy I), as do most dicots and nongraminous monocots. This strategy relies on the secretion of protons into the rhizosphere by AHA2 (ARABIDOPSIS H<sup>+</sup> ATPASE 2) to decrease the pH of the soil solution and solubilize oxidized iron (Fe<sup>3+</sup>), which is then reduced to Fe<sup>2+</sup> by FRO2 (ferric reduction oxidases 2), and subsequently taken up into the root by IRT1 (iron-regulated transporter 1). This process is tightly regulated since, in excess, iron is also detrimental to the plant because of its capacity to generate reactive oxygen species (ROS) via the Fenton reaction.</p><p>The regulation of Iron homeostasis is well-conserved in plants, and is primarily controlled at the transcriptional level (Berger <i>et al</i>., <span>2023</span>; Li <i>et al</i>., <span>2023</span>). It relies on an intricate regulatory network involving several regulatory proteins, among which the bHLH (basic helix–loop–helix) transcription factors play a preponderant role (Fig. 1). For instance, Arabidopsis has 17 different bHLH proteins (from six bHLH clades) that regulate iron homeostasis. This regulatory network is composed of two modules. The first module relies on FIT/bHLH29 (FER-LIKE IRON DEFICIENCY INDUCED TRANSCRIPTION FACTOR; clade IIIa). FIT is a direct positive regulator of <i>FRO2</i> and <i>IRT1</i> expression (Fig. 1). To achieve its function, FIT interacts with bHLH38, bHLH39, bHLH100, and bHLH101 (clade Ib), forming heterodimers with partially overlapping roles. In the second module, another set of bHLH transcription factors positively regulate the expression of <i>FIT</i> and clade Ib bHLHs (Fig. 1). It involves ILR3/bHLH105 (iaa-leucine resistant 3), IDT1/bHLH34 (iron deficiency tolerant 1), bHLH104, bHLH115 from clade IVc, and URI/bLHL121 (UPSTREAM REGULATOR OF IRT1) from clade IVb (Tissot <i>et al</i>., <span>2019</span>; Gao <i>et al</i>., <span>2020</span>). By contrast, PYE/bHLH47 (POPEYE; clade IVb) is a negative regulator of clade Ib bHLH expression (Pu & Liang, <span>2023</span>).</p><p>In their study, Yang <i>et al</i>. demonstrated that the H2B histone variant HTB4 negatively regulates leaf senescence in an iron-dependent manner.

Renner","doi":"10.1111/nph.19201","DOIUrl":"https://doi.org/10.1111/nph.19201","url":null,"abstract":"<p>There is much circumstantial evidence that flowering plants were diverse by the Lower Cretaceous and were pollinated by insects (Arber & Parkin, <span>1907</span>; Crepet & Friis, <span>1987</span>). Arguments supporting this come from extant and fossil flower morphology, fossilized traces of interactions, and the pollination modes of surviving early lineages. First, some extinct gymnosperms had bisporangiate cones (with both micro- and megasporangia) surrounded by bracts (Fig. 1), and many such cones show traces of having been chewed by mandibulate insects (Peris <i>et al</i>., <span>2017</span>). Fossils of flower-associated flies also provide evidence of the existence of strobilus–pollinator interactions from the Permian to the Jurassic (Ren, <span>1998</span>; Ren <i>et al</i>., <span>2009</span>; Khramov <i>et al.</i>, <span>2023</span>). Second, if flowers evolved from bisporangiate strobili, they were not well suited for wind pollination because simultaneous optimization for pollen export and pollen capture is structurally difficult. The angiosperms' defining enclosure of the megasporangium inside surrounding structures may also point to ancestral insect pollination, as argued by Arber & Parkin (<span>1907</span>: 73), ‘In the case of the angiosperms such primitive entomophily was preserved and rendered permanent by a transference of the pollen-collecting mechanism from the ovule itself to the carpel or megasporophyll and by the closure of this organ.’ Third, all angiosperms, but no living gymnosperm, produce pollenkitt, an oily substance on the surface of pollen that serves as a glue to attach pollen to animal vectors (Hesse, <span>1980</span>). In wind-pollinated plants, pollenkitt abundance is secondarily reduced. Lastly, the oldest lineages of flowering plants that still survive today are pollinated by flies, moths, and beetles (Luo <i>et al</i>., <span>2018</span>).</p><p>While insect pollination thus undoubtedly played a decisive role in the evolution of flowers, a phylogenetically informed analysis of pollination by insects, vertebrates, wind, and water across a full modern phylogeny of plants has been lacking. This is what Stephens <i>et al</i>. now provide in an article published in this issue of <i>New Phytologist</i> (<span>2023</span>; 880–891). Using a time-calibrated phylogeny with 1201 species representing the major lineages of flowering plants, together with geographic occurrence data, Stephens <i>et al</i>. quantified the timing and environmental associations of pollination shifts. Where possible, they scored pollination at the species level, either from published fieldwork (<i>n</i> = 432) or from the pollinator syndrome approach (<i>n</i> = 728). Where no information was available for a particular species, taxa were scored at genus (<i>n</i> = 131) or family (<i>n</i> = 4) level.
