Boron is an essential microelement for plant growth. Tomato is one of the most cultivated fruits and vegetables in the world, and boron deficiency severely inhibits its yield and quality. However, the mechanism of tomato in response to boron deficiency remains largely unclear. Here, we investigated the physiological and molecular bases of the boron deficiency response in hydroponically grown tomato seedlings. Boron deficiency repressed the expression of genes associated with nitrogen metabolism, while it induced the expression of genes related to the pentose phosphate pathway, thereby altering carbon flow to provide energy for plants to cope with stress. Boron deficiency increased the accumulation of copper, manganese and iron, thereby maintaining chlorophyll content and photosynthetic efficiency at the early stage of stress. In addition, boron deficiency downregulated the expression of genes involved in cell wall organization and reduced the contents of pectin and cellulose in roots, ultimately retarding root growth. Furthermore, boron deficiency markedly altered phytohormone levels and signaling pathways in roots. The contents of jasmonic acid, jasmonoy1-L-isoleucine, trans-zeatin riboside, abscisic acid, salicylic acid and SA glucoside were decreased; in contrast, the contents of isopentenyladenine riboside and ethylene precursor 1-aminocyclopropane-1-carboxylic acid were increased in the roots of boron-deficient tomato plants. These results collectively indicate that tomato roots reprogram carbon/nitrogen metabolism, alter cell wall components and modulate phytohormone pathways to survive boron deficiency. This study provides a theoretical basis for further elucidating the adaptive mechanism of tomato in response to boron deficiency.

“…Os nutrientes foliares influenciaram a produção de algodão em caroço, a produção de fibra e o rendimento de fibra (Figura 2; Tabelas 5 e 6), de acordo com várias referências. Os teores de nutrientes foliares são reflexos da fertilidade do solo, que tanto podem aumentar a produção de algodão (Kurt & Temiz, 2016;Shah et al, 2017;Win et al, 2017;Ali et al, 2018;Ahmad et al, 2019;Ali et al, 2020), não alterar a produção de algodão (Silva et al, 2016;Haliloglu, 2019), ou até reduzir a produção de algodão (Seçer et al, 2016;Ajmal et al, 2018).…”

A produção de algodão representa uma importante cultura agrícola do Brasil. Portanto se faz necessário estudos que relacionam atributos físicos do solo com produção de fibra e produção de algodão em caroço. Sendo assim, este trabalho teve como objetivo determinar a influência dos atributos físicos do solo: argila, areia, silte, microporosidade, macroporosidade, porosidade total e densidade, na forma colhida do algodão. Realizamos análise de correlação canônica, utilizando os dados amostrais obtidos de 193 amostras de solo, coletadas em 100 talhões com 13 cultivares de algodão, entre 63 e 136 dias após a emergência, distribuídos em 3 regiões do estado de Mato Grosso, em altitudes de 402 a 885m. A análise de correlação canônica explicou 82,99% da variação dos dados amostrais. Os atributos físicos do solo influenciaram na produção do algodoeiro, no rendimento de fibra e na produção de algodão em caroço, nesta ordem: (Silte = Microporosidade) > (Argila = Macroporosidade = Areia) >> microporosidade, porosidade Total > Densidade. Os atributos densidade, porosidade total e macroporosidade não afetaram na produção de fibra, respectivamente. Neste sentido os atributos físicos do solo alteram a qualidade da fibra.

“…The soil B concentration of 0.60 mg•kg −1 extracted with hot water has been considered as the threshold for general crops (Aitken and McCallum 1988) while 0.4∼0.55 mg•kg −1 for cotton (Oosterhuis 2001). Ahmad et al (2019) reported that sandy texture, high pH, and low organic matter content could be the main reasons for low B availability for cotton. Furthermore, high calcium carbonate not only increases the soil pH to reduce B availability but also serves as the binding site for the adsorption of soluble B (Shaaban et al 2004;Shaaban and Helmy 2006).…”

Background Boron (B) deficiency is an important factor for poor seed cotton yield and fiber quality. However, it is often missing in the plant nutrition program, particularly in developing countries. The current study investigated B's effect on growth, yield, and fiber quality of Bt (CIM-663) and non-Bt (Cyto-124) cotton cultivars. The experimental plan consisted of twelve treatments: Control (CK); B at 1 mg·kg−1 soil application (SB1); 2 mg·kg−1 B (SB2); 3 mg·kg−1 B (SB3); 0.2% B foliar spray (FB1); 0.4% B foliar spray (FB2); 1 mg·kg−1 B + 0.2% B foliar spray (SB1 + FB1); 1 mg·kg−1 B + 0.4% B foliar spray (SB1 + FB2); 2 mg·kg−1 B + 0.2% B foliar spray (SB2 + FB1); 2 mg·kg−1 B + 0.4% B foliar spray (SB2 + FB2); 3 mg·kg−1 B + 0.2% B foliar spray (SB3 + FB1); 3 mg·kg−1 B + 0.4% B foliar spray (SB3 + FB2). Each treatment has three replications, one pot having two plants per replication. Results B nutrition at all levels and methods of application significantly (P ≤ 0.05) affected the growth, physiological, yield, and fiber quality characteristics of both cotton cultivars. However, SB2 either alone or in combination with foliar spray showed superiority over others, particularly in the non-Bt cultivar which responded better to B nutrition. Maximum improvement in monopodial branches (345%), sympodial branches (143%), chlorophyll-a (177%), chlorophyll-b (194%), photosynthesis (169%), and ginning out turn (579%) in the non-Bt cultivar was found with SB2 compared with CK. In Bt cultivar, although no consistent trend was found but integrated use of SB3 with foliar spray performed relatively better for improving cotton growth compared with other treatments. Fiber quality characteristics in both cultivars were improved markedly but variably with different B treatments. Conclusion B nutrition with SB2 either alone or in combination with foliar spray was found optimum for improving cotton's growth and yield characteristics.
