Abstract	The study evaluated the effects of R-limonene, in sublethal concentration, on the histology, histochemistry, biochemistry, and carbohydrates and proteins levels in the third instar Aedes aegypti larvae. The R-limonene (LC50 of 27 ppm) and control groups were analyzed 12 and 24 h after the beginning of treatments. The midgut of the control larvae was composed of cylindrical and elongated cells with a spherical and central nucleus and regenerative cells with a pyramidal shape. After 12 h of treatment, columnar cells, protuberances, and cytoplasmic vacuolization were found. However, 24 h after treatment, complete disorganization of the epithelium was observed. There was a positive reaction in all treatments for the presence of glycogen. However, the midgut of larvae treated with R-limonene showed higher levels. For the total protein, positive marking occurred in all groups evaluated, with higher levels in treatments and the lowest in control 12 h. The levels of total protein and glycogen increased in the treated larvae compared to the 12 h control. Besides, a reduction in total sugar levels was observed in the treated larvae compared to controls 12 and 24 h, being more evident in the last one. Therefore, these results demonstrate that R-Limonene caused pathological changes in the epithelium of the A. aegypti midgut at histophysiological and biochemical levels.

Abstract	Hemidesmus indicus (L.) R. Br. ex Schult is commonly known as anantmul or Indian sarsaparilla. The roots of this plant, which display a wide range of medicinal, biological, and phytopharmaceutical properties, are used in the pharmaceutical and food industries. Conventionally, the plant is propagated by seed germination or vegetatively, but the efficacy of traditional methods has some limitations: plants derived from seed germination are prone to seed-borne diseases, or plantlet production using vegetative propagation is limited. In contrast, plant tissue culture allows for large-scale propagation and secondary metabolite production in vitro without sacrificing plants from their natural habitats. Many efforts have been made over 40 years of research to establish efficient micropropagation protocols to speed up cultivation of this plant, including callus-mediated in vitro propagation, somatic embryogenesis, and shoot multiplication using cotyledenory nodes, stem segments, shoot tips, and nodal explants. Among these explants, nodal explants are the most commonly used for H. indicus micropropagation. The application of adenine sulfate, citric acid, ascorbic acid, and arginine may be useful in preventing explant browning, premature leaf senescence, and shoot tip abscission during in vitro culture. This review provides insight into micropropagation, use of synthetic seeds for short-term germplasm preservation, and in vitro production of secondary metabolites such as 2-hydroxy-4-methoxybenzaldehyde, lupeol, vanillin, and rutin, from in vitro root and callus cultures. Furthermore, unexplored and possible innovative areas of research in Hemidesmus biotechnology are also discussed. KEY POINTS: • Hemidesmus indicus has multiple therapeutic applications. • H. indicus roots are used in confectionary and pharmacy. • This review comprehensively assesses H. indicus tissue culture. • Challenges and future research of H. indicus biotechnology are discussed.

Abstract	The study evaluated the effects of R-limonene, in sublethal concentration, on the histology, histochemistry, biochemistry, and carbohydrates and proteins levels in the third instar Aedes aegypti larvae. The R-limonene (LC50 of 27 ppm) and control groups were analyzed 12 and 24 h after the beginning of treatments. The midgut of the control larvae was composed of cylindrical and elongated cells with a spherical and central nucleus and regenerative cells with a pyramidal shape. After 12 h of treatment, columnar cells, protuberances, and cytoplasmic vacuolization were found. However, 24 h after treatment, complete disorganization of the epithelium was observed. There was a positive reaction in all treatments for the presence of glycogen. However, the midgut of larvae treated with R-limonene showed higher levels. For the total protein, positive marking occurred in all groups evaluated, with higher levels in treatments and the lowest in control 12 h. The levels of total protein and glycogen increased in the treated larvae compared to the 12 h control. Besides, a reduction in total sugar levels was observed in the treated larvae compared to controls 12 and 24 h, being more evident in the last one. Therefore, these results demonstrate that R-Limonene caused pathological changes in the epithelium of the A. aegypti midgut at histophysiological and biochemical levels.

Abstract: ... polycyclic aromatic hydrocarbons (PAHs) from jambu (Acmella oleracea (L.) R.K. Jansen), a high chlorophyll matrix ...

Abstract	A Plackett-Burman design was used to develop an extraction method for eleven polycyclic aromatic hydrocarbons (PAHs) from jambu (Acmella oleracea (L.) R.K. Jansen), a high chlorophyll matrix. For this, a QuEChERS method was used, followed by two clean-up steps: a dispersive solid-phase extraction (d-SPE) with PSA, SAX, C₁₈, and MgSO₄, and a liquid-liquid extraction with hexane. Clear extracts with a visible reduction in the chlorophyll content were reached. Gas chromatograph mass spectrometry (GC–MS) was used for quantification. The method was validated in terms of limits of detection (LOD) and quantification (LOQ), linearity, matrix effect, precision, and recovery. The incidence of benzo(a)anthracene and benzo(b)fluoranthene in jambu was observed below the LOQ. On the other hand, chrysene was quantified in concentrations varying from 1.49 to 2.76 μg.kg⁻¹. For the first time, these compounds were detected in jambu.

Abstract	Jambu (Acmella oleracea (L.) R.K. Jansen) is a neglected plant native to the Amazon Biome. Although it is very consumed in the north of Brazil, little is known about its chemical and nutritional composition. Thus, this study aimed to characterize jambu and to evaluate the effects of the boiling process on its chemical composition. The proximate composition, minerals, total amino acids, fatty acids levels, and phytosterols were determined. In comparison with conventional vegetables jambu presented higher levels of protein (24.01%), ash (10.92%), total fiber (62.61%) some mineral such as Ca (2551.56 mg/100 g), Mg (734 mg/100 g) and Cu (2.09 mg/100 g), and amino acids such as asparagine (32.01 mg/g), glutamic acid (28.26 mg/g), valine (14.55 mg/g) and isoleucine (14.19 mg/g). A significant reduction was observed in carbohydrates, total dietary fibers, minerals, unsaturated fatty acids, and in some amino acid levels after the boiling process, with an increase in ash content, protein, and saturated fatty acids in the heat-treated jambu. Lipids, phytosterols, and some amino acid levels were not significantly affected by the hydrothermal process. Thus, this study has shown that raw and processed jambu may be good alternatives for conventional vegetables, even with nutrients losses during boiling.

Abstract	Millet is a species of the grass family used in cattle pastures, for hay, for silage, and in soil cover in no-tillage systems. However, studies on seed production and post-harvest techniques for this species have not been sufficiently developed, considering the demand for and potential of this crop. The objective of this study was to monitor the physiological quality of millet seeds stored in porous packaging. Millet seeds were stored under four ambient conditions (natural laboratory environment, dry chamber, refrigerator, and freezer). Physiological quality was evaluated by germination and vigor tests before and during storage each year, up to six years for the dry chamber and natural laboratory environment, and up to 12 years for the refrigerator and freezer. Analysis of variance was conducted on the data, which were in 4 × 6 and 2 × 12 (environment and storage period) factorial arrangements. The means of the environments were compared by the Tukey test (p ≤ 0.05) and the storage periods by regression analysis. The germination capacity of millet seeds is best conserved in a refrigerator and freezer, and they remain viable for up to twelve years of storage under these conditions.

Abstract	Silicon (Si) it is a beneficial element that relieves biotic and abiotic stresses in plants. However, cotton plants are not considered Si accumulators, with low potential for uptake the element by roots. The objective of this study was to evaluate the effect of combinations of Si rates applied by leaf spray and soil on the physiology, growth and yield of cotton (Gossypium hirsutum L. r. latifolium Hutch). The experimental design was a randomized complete block in a 3 x 4 factorial scheme with four replications. Leaf spraying consisted of three Si concentrations (0, 500, and 1000 mL ha-1) corresponding to 0, 100, and 200 ml ha-1 of monosilicic acid, with spraying split into three applications at stages V4, V6 and V8. Soil-based fertilization consisted of four Si rates in (0, 2.5, 5.0, and 10.0 kg ha-1) corresponding to 0, 0.5, 1.0, and 2.0 kg ha-1 of SiO2. At flowering, photosynthesis, green color index (GCI), plant height, and NDVI were evaluated. The application of Si in the planting furrow near the rhizosphere increased the green color index, reflecting a gain in photosynthesis and plant height, which positively increased NDVI. The use of high solubility Si in the planting furrow can increase the concentration of monosilicic acid in the area with the highest root distribution, enhancing the effect of this element in a non-accumulator crop such as cotton, by improving the green color index, photosynthesis and hence reflecting on gains in plant height and plant leaf area demonstrated by NDVI.

Abstract	Objetivou-se estimar a capacidade geral de combinação (CGC) e a capacidade específica de combinação (CEC) de dez características morfoagronômicas, por meio de cruzamentos dialélicos entre onze genótipos de capim-elefante (Pennisetum purpureum Schum.) e doze de milheto (Pennisetum glaucum (L.) R. Br.) utilizando o método 4 domodelo proposto por Griffing (1956). Os 132 híbridos interespecíficos foram avaliados no delineamento em blocos ao acaso, com três repetições de tratamentos, de março de 2001 a abril de 2002, na Embrapa Gado de Leite, Coronel Pacheco, Estado de Minas Gerais.Observou-se variabilidade genética nitidamente superior entre os genitores de capimelefante. Desse modo, convém frisar que a estratégia de melhoramento intra-específico, principalmente em capim-elefante, poderá proporcionar maiores ganhos para a maioria dascaracterísticas do que a praticada de forma interespecífica. As melhores combinações híbridas para produção de forragem, tanto da planta integral, quanto da fração foliar, foram BAG-64 x Wrajpop 88, BAG-64 x HiGrop, BAG-19 x BN 2 e BAG-19 x NPM 1. This work aimed to estimate general combining ability (GCA) and specific combining ability (SCA) in ten morphoagronomic characteristics through diallel crossing among eleven elephantgrass (Pennisetum purpureum Schum.) and twelve pearl millet (Pennisetum glaucum (L.) R. Br.) genotypes using the method 4, Griffing (1956) model. The 132 interespecific hybrids were evaluated in a complete randomized block design, with three replications, from march of 2001 to april of 2002, in Embrapa Gado de Leite, Coronel Pacheco, Minas Gerais State. The genetic variability was superior in elephantgrass genitors, so that intraspecific breeding, mainly in elephantgrass, can result in greater gains to almost all characteristics than to intraspecific mode. The best hybrid combinations to forage production, both in integral plant and in leaf fraction, were BAG-64x Wrajpop 88, BAG-64 x HiGrop, BAG-19 x BN 2, and BAG-19 x NPM 1.
