Wimmer","doi":"10.1002/jpln.70081","DOIUrl":"https://doi.org/10.1002/jpln.70081","url":null,"abstract":"&lt;p&gt;In the early 20th century, plant nutrition was dominated by the soil chemistry paradigm of nitrogen, phosphorus, and potassium. Micronutrients were largely ignored and poorly understood, partly because existing methods did not allow precise adjustment of micronutrient levels in plant growth media. The importance of most of today's known essential micronutrients, including boron (B), was largely overlooked, even though abnormal crop growth on certain soils could be “rescued” by adding B. In 1923, a century ago, the situation changed when Katherine Warington showed that certain vascular plants, such as pea, cannot reproduce without B, and that different plant species had different quantitative B demands (Warington &lt;span&gt;1923&lt;/span&gt;). Boron was then added to the list of essential mineral elements for plants, marking the beginning of a new chapter in plant nutrition research.&lt;/p&gt;&lt;p&gt;In the first decades (1920–1950s), B research was pragmatic and descriptive. Agronomists documented B deficiency symptoms in many crops and fruit trees, including cracked and hollow stems, curled and lanceolated leaves, deformed vascular tissue in stems, leaves, and roots, deformed and withered flowers, poor fruit set, and reduced seed formation. In many seed plants, insufficient B supply caused reduced shoot and root growth and lower fertility. Critical B concentrations in soil or aboveground tissues at which development is impaired and deficiency symptoms appear were determined for various plants. On the basis of these &lt;i&gt;in terra&lt;/i&gt; and &lt;i&gt;in planta&lt;/i&gt; data, B requirements were defined and plants classified as low-B-demanding (mainly graminaceous monocots) or high-B-demanding (non-graminaceous monocots and eudicots). Consistent with Warington (&lt;span&gt;1923&lt;/span&gt;), large variation in both critical B concentrations and B toxicity thresholds was found among different species or even cultivars. It was shown that bioavailable B levels in soils determine plant health, and the effectiveness of different B fertilizer forms and soil and foliar B fertilization management strategies were tested to improve yields.&lt;/p&gt;&lt;p&gt;In the following decades (1960–1980s), as understanding of plant physiology grew and new experimental and analytical methods emerged, B research rapidly expanded beyond agronomy and focused on B's essential role in plants and the cause of specific B deficiency symptoms. Boron was shown to be required for cell division and elongation, especially in root and shoot meristems and newly formed tissues, and for pollen germination and tube growth. Controlled experiments distinguished B's role from other micronutrients, reinforcing its status as essential. Boron deficiency was linked to altered cell differentiation and disrupted cell wall structure, particularly the integrity and physicochemical properties of the pectin-rich primary cell walls of growing tissues. By the late 20th century, B's essentiality and many physiological consequences of its deficiency had been de","PeriodicalId":16802,"journal":{"name":"Journal of Plant Nutrition and Soil Science","volume":"189 3","pages":"289-291"},"PeriodicalIF":2.8,"publicationDate":"2026-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jpln.70081","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148153561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

B deficiency and toxicity are widespread agricultural problems worldwide. To maintain appropriate B levels in tissues, plants require B-sensing mechanisms to regulate its transport. In <i>Arabidopsis thaliana</i>, the boric channel NIP5;1, the borate transporter BOR1, and their homologs in the plasma membrane are responsible for efficient uptake and translocation of B when its supply is limited. Importantly, these transport systems are downregulated under high-B conditions at multiple post-transcriptional levels. NIP5;1 is downregulated by mRNA degradation following the B-dependent ribosome stalling at the minimum upstream open reading frame (uORFs, AUGUAA) in the 5′ untranslated region (5′ UTR). Upon high B supply, BOR1 is ubiquitinated and transported to the vacuole via the endocytic pathway for degradation. Under higher B supply, BOR1 is further downregulated by translational suppression dependent on multiple uORFs in the 5′ UTR. These responses are important for preventing B toxicity. High-B-induced ubiquitination of BOR1 was shown to be dependent on its transport activity, suggesting that conformation transition during the borate transport cycle in the plasma membrane controls the rate of ubiquitination. The ribosome stalling that leads to mRNA degradation of <i>NIP5;1</i> and translational suppression of BOR1 is presumably dependent on B binding to factors involved in translation in the cytosol.
