“…During this process, the cell wall is modified and the proteomic and metabolomic profilings of the plant change [19,20]. The freezing tolerance of alfalfa ( Medicago sativa ), eucalypt ( Eucalyptus nitens ) and tomato ( Solanum lycopersicum ) were improved after cold acclimation treatment [21,22,23]. It has been proven that CBF genes are involved in cold acclimation in Arabidopsis, and that the CBFs are also important for salt tolerance of plant [24].…”

Excess salinity is a major environmental stress that limits growth and development of plants. Improving salt stress tolerance of plants is important in order to enhance land utilization and crop yield. Cold priming has been reported to trigger the protective processes in plants that increase their stress tolerance. Bermudagrass (Cynodon dactylon) is one of the most widely used turfgrass species around the world. However, the effect of cold priming on salt tolerance of bermudagrass is largely unknown. In the present study, wild bermudagrass was pre-treated with 4 °C for 6 h before 150 mM NaCl treatment for one week. The results showed that the cell membrane stability, ion homeostasis and photosynthesis process which are usually negatively affected by salt stress in bermudagrass were alleviated by short-term pre-cold treatment. Additionally, the gene expression profile also corresponded to the change of physiological indexes in bermudagrass. The results suggest that cold priming plays a positive role in improving salt stress tolerance of bermudagrass.

“…Low temperature is a major constraint on the growth, geographical distribution, and yield of some plants. Cold resistance of many plants[ 1 – 4 ], e.g. Eucalyptus nitens , Miscanthus , Medicago sativa and North American Rhododendron can be improved by prior exposure to a period of low, nonfreezing temperatures, which known as cold acclimation (CA) [ 5 – 7 ].…”

Comparative analysis of the response and gene regulation in cold resistant and susceptible tea plants

Cold environment is the main constraint for tea plants (Camellia sinensis) distribution and tea farming. We identified two tea cultivars, called var. sinensis cv. Shuchazao (SCZ) with a high cold-tolerance and var. assamica cv. Yinghong9 (YH9) with low cold-tolerance. To better understand the response mechanism of tea plants under cold stress for improving breeding, we compared physiological and biochemical responses, and associated genes expression in response to 7-day and 14-day cold acclimation, followed by 7-day de-acclimation in these two tea cultivars. We found that the low EL50, low Fv/Fm, and high sucrose and raffinose accumulation are responsible for higher cold tolerance in SCZ comparing with YH9. We then measured the expression of 14 key homologous genes, known as involved in these responses in other plants, for each stages of treatment in both cultivars using RT-qPCR. Our results suggested that the increased expression of CsCBF1 and CsDHNs coupling with the accumulation of sucrose play key roles in conferring higher cold resistance in SCZ. Our findings have revealed key genes regulation responsible for cold resistance, which help to understand the cold-resistant mechanisms and guide breeding in tea plants.

“…Os principais benefícios são uma extração mais eficaz, portanto, economia de energia, e também o uso de temperaturas moderadas, o que é benéfico para compostos sensíveis ao calor (ESCLAPEZ et al, 2011). Com a possibilidade do uso do óleo da semente de H. brasiliensis, ganham destaque estudos visando à otimização da produção de óleo dessas sementes por meio de extração assistida por ultrassom, técnica que já é utilizada para extração de óleo em: semente de melão, casca de romã, jabuticaba, cogumelos, sementes de uva, soja, e alho (AGUILÓ- AGUAYO et al, 2017;PORTO;PORRETTO;DECORTI, 2013;GAETE-LOYOLA et al, 2017;LI;PORDESIMO;WEISS, 2004;MOORTHY et al, 2015;TOMŠIK et al, 2016). Pelos resultados apresentados nos trabalhos, verifica-se a viabilidade da implantação das inovações voltadas para a extração do óleo (MABAYO et al, 2018).…”

A busca por inovações tecnológicas é uma importante ferramenta de auxílio para o planejamento da conservação das espécies florestais e seus produtos não madeireiros. Este trabalho objetiva realizar um estudo de prospecção científica e tecnológica do uso e do potencial de sementes florestais. Para a busca dos artigos, foram utilizadas as plataformas Scopus e Web of Science. As análises estatísticas foram geradas com o auxílio do pacote Bibliometrix do software R. As patentes foram prospectadas e analisadas usando-se o Orbit Intelligence. Foram mapeados 229 artigos e 387 documentos de patentes. A China é o principal detentor das patentes, incluindo produtos patenteados a partir de espécies florestais brasileiras. Embora o Brasil apareça como um dos países depositários, com destaque para as espécies nativas, ele não foi o país de origem de nenhuma patente da pesquisa. As patentes foram desenvolvidas principalmente para atender às indústrias de alimentos, de medicamentos e de cosméticos.
