“…Desorption was performed directly in the gas chromatograph injector port over 10 min at 250 • C using the splitless mode. Some combinations of GC-MS created oven temperature programming were tested to improve the separation of chromatographic peaks, as previously proposed by Terra et al (2020) [43], as shown in Table 2. The detection was performed using 70 eV of ionization energy in a mass range of 40-550 a.m.u.…”

Lethal bronzing (LB) is a fatal infection that affects over 20 species of palms (Arecaceae) and is caused by the phytoplasma ‘Candidatus Phytoplasma aculeata’. This pathogen causes significant economic losses to landscape and nursery companies in Florida, USA. Recently, the vector was determined to be the planthopper Haplaxius crudus, which was more abundant on LB-infected palms. Herein, the volatile chemicals emitted from LB-infected palms were characterized using headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry (HS-SPME/GC-MS). Infected Sabal palmetto were identified and confirmed as positive for LB via quantitative PCR. Healthy controls of each species were selected for comparison. All infected palms exhibited elevated levels of hexanal and E-2-hexenal. Threatened palms showed high releasing concentrations of 3-hexenal and Z-3-hexen-1-ol. The volatiles characterized herein are common green-leaf volatiles (GLVs) emitted by plants under stress. This study considers the first documented case of GLVs in palms attributed to phytoplasma infection. Due to the apparent attraction of LB-infected palms to the vector, one or several of the GLVs identified in this study could serve as a lure for the vector and supplement management programs.

“…O mamoeiro (Carica papaya L.) é uma planta tropical da família Caricaceae, cujo fruto é amplamente consumido devido ao seu sabor agradável e ao seu alto valor nutricional, já que possui elevado teor de vitaminas A e C, minerais, carotenoides e açúcares (TERRA et al, 2020;SANTANA;. A origem da espécie é provavelmente no Noroeste da América do Sul, na Bacia Amazônica Superior, onde sua diversidade genética é máxima (OLIVEIRA; COELHO, 2021).…”

The aim of this study was to characterize a papaya variety grown in Alto Solimoes, Amazonas, identifying the most important descriptors for recognizing the variety and describing the variety based on its morphological and agronomic characteristics. The study consisted of 30 plants. The qualitative data was described, while the quantitative data was submitted to descriptive statistical analysis. The results showed that the variety has peculiar characteristics, such as purple-medium stem pigmentation, the absence of hermaphrodite flowers and the light orange color of the fruit pulp at the horticultural maturity point. Thus, preserving this variety is essential, considering its local commercial relevance and its potential for future genetic improvement programs.

The plant Momordica charantia (Cucurbitaceae), popularly known as bitter melon, snake fruit, Saint Vincent's herb, or little melon, is an African species that has developed in tropical and subtropical biomes in various parts of Brazil. The fruit is used in various traditional medicinal applications. The study aimed to identify the compounds of the essential oil of the leaves obtained by hydrodistillation and in the fruit through Solid-Phase Microextraction by headspace mode (HS-SPME) coupled to gas chromatography-mass spectrometry (GC-MS).The analysis of mature fruits led to the identification of 18 compounds, compared to the hydrodistillation, in which 21 compounds were identified. Benzaldehyde, linalool, and βcyclocitral were identified in both methods. Linalool was the major compound in both processes. These findings highlight the importance of knowing the chemical composition of organic volatile compounds (VOCs), given the potential for medicinal applications and popular use of plants.
