“…This is consistent with the findings for Norway spruce (Picea abies) (Mö ttö nen et al 2001) and canola (Brassica napus L.) (Asad et al 2002). This phenomenon may be ascribed partly to the impairments of vascular tissues induced by B deficiency (Dell and Huang 1997). Our results also indicated that more B was distributed to the roots of citrange-grafted plants than those of trifoliate orange-grafted plants at the end of this experiment (Fig.…”

“…It plays important roles in stability of cell walls (Matoh 1997) and cellular activities (Cakmak and Rö mheld 1997). Boron deficiency in plants may restrain root elongation through limiting cell enlargement and cell division in the growing zone of root tips, and possibly impede leaf expansion due to the decrease of the photosynthetic capacity (Dell and Huang 1997). Factors affecting B availability to plants are solution pH, texture, moisture, temperature, organic matter, and clay mineralogical characteristics (Shorrocks 1997).…”

Boron (B) deficiency is widespread and serious in navel orange orchards in southern Jiangxi in China and has been considered an important soil constraint to citrus yield and quality. It has been observed that there was great variation in responses to different B supply levels between ''Newhall'' navel orange grafted on citrange and trifoliate orange. The aim of this work was to compare the different responses of the two scion-rootstock combinations under different B stresses (low and high) in young citrus trees. ''Newhall'' navel orange grafted on citrange or trifoliate orange were incubated in nutrient solution containing different levels of B (0, 0.5 and 5.0 mg L À1 ), of which 0 and 5.0 mg L À1 were considered as deficient and excessive B and 0.5 mg L À1 was considered as an appropriate level of B. The experiment was carried out in a greenhouse for 117 days. The results showed that, under low B or high B conditions, better growth performance was observed in ''Newhall'' plants grafted on citrange than in those grafted on trifoliate orange, suggesting that citrangegrafted plants were more tolerant to deficient and excessive B than the plants grafted on trifoliate orange. Boron seemed to be preferentially translocated to the new leaves (leaves from current year), and resulted in normal growth of young leaves under limited B supply. Boron distribution in different plant parts indicated that there was a restriction in translocation of B from roots to scion tissues (stems and leaves of scion) under limited B availability. The relatively high B concentration observed in plants grafted on trifoliate orange suggested higher demand for B than those grafted on citrange. There existed a balance within the B forms to maintain normal growth. Thus, R value (R ¼ semi-bound B/free B) was much higher in citrange-grafted plants than in trifoliate orange-grafted plants under the same B supply level. This explained why citrange-grafted plants had less B but produced relatively more dry mass at cellular level. These results suggested that the utilization efficiency of B of citrange-grafted plants was probably greater than trifoliate orange-grafted plants.

“…In general, B-deficiency symptoms first appear in growing regions rather than in mature tissues, e.g., rapid cessation of root elongation, reduced leaf expansion, and reduced fertility (Loomis and Durst 1992;Marschner 1995;Dell and Huang 1997). A number of experiments have demonstrated that the primary effect of B deficiency is the reduction of cell enlargement (Dell and Huang 1997, for review).…”

“…Except some plant species producing sugar alcohols such as sorbitol and mannitol, B is immobile in most plant species (Brown and Shelp, 1997). Therefore, a continuous supply of B is required to maintain growth of newly developing tissues, and deficiency of B will result in the cessation of root elongation, reduced leaf expansion, and loss of fertility (Dell and Huang 1997;Loomis and Durst 1992;Marschner 1995). On the other hand, B also shows toxicity to plants when present in excess, which symptoms are characterized by chlorosis and necrosis at the tips of older leaves (Schnurbusch et al, 2010).…”

Preferential Distribution of Boron to Developing Tissues Is Mediated by the Intrinsic Protein OsNIP3

et al. 2017

Boron is especially required for the growth of meristem and reproductive organs, but the molecular mechanisms underlying the preferential distribution of B to these developing tissues are poorly understood. Here, we show evidence that a member of nodulin 26-like intrinsic protein (NIP), OsNIP3;1, is involved in this preferential distribution in rice (Oryza sativa). OsNIP3;1 was highly expressed in the nodes and its expression was up-regulated by B deficiency, but down-regulated by high B. OsNIP3;1 was polarly localized at the xylem parenchyma cells of enlarged vascular bundles of nodes facing toward the xylem vessels. Furthermore, this protein was rapidly degraded within a few hours in response to high B. Knockout of this gene hardly affected the uptake and root-to-shoot translocation of B, but altered B distribution in different organs in the above-ground parts, decreased distribution of B to the new leaves, and increased distribution to the old leaves. These results indicate that OsNIP3;1 located in the nodes is involved in the preferential distribution of B to the developing tissues by unloading B from the xylem in rice and that it is regulated at both transcriptional and protein level in response to external B level.
