In our study, we investigated some physiological and ecological aspects of the life Cuscuta racemosa Mart. (Convolvulaceae) plants with hypothesis that they recognise different hosts at a distance from them, change their survival strategy depending on what detect. We also hypothesised that, as an attempt prolonging through photosynthesis, synthesis chlorophylls (a phenomenon not completely explained in these parasitic plants) would be increased if don’t detect host. quantified pigments...
To survive in a dynamic environment growing fixed to the ground, plants have developed mechanisms for monitoring and perceiving environment. When stimulus is perceived, series of signals are induced can propagate away from stimulated site. Three distinct types systemic signaling exist, i.e., (i) electrical, (ii) hydraulic, (iii) chemical, which differ not only their nature but also propagation speed. Naturally, suffer influences two or more stimuli (biotic and/or abiotic). Stimuli...
The electrical activity of tomato plants subjected to fruit herbivory was investigated. study aimed test the hypothesis that fruits transmit long-distance signals shoot when herbivory. For such, time series classification by machine learning techniques and analyses related oxidative response were employed. Tomato (cv. “Micro-Tom”) placed into a Faraday's cage an electrode pair inserted in fruit's peduncle. Helicoverpa armigera caterpillars on (either green ripe) for 24 h. recorded before...
Fruits, like other parts of the plant, appear to have a rich electrical activity that may contain information. Here, we present data showing differences in electrome complexity tomato fruits through ripening and discuss possible physiological processes involved. The signals, measured approximate entropy, varied along fruit process. When analyzing individually, decrease entropy values was observed when they entered breaker stage, followed by tendency increase again light red stage....
ABSTRACT This study aimed to prepare jellies of conventional type red strawberry guava (with added sucrose) and no sugar evaluate the physical chemical composition content bioactive compounds in them. Four formulations were prepared: with addition sucrose (F1), aspartame (F2), saccharin cyclamate (F3), acesulfame sucralose (F4). Physicochemical analysis pH carried out, as well titratable acidity, total soluble solids, ashes, proteins, lipids, moisture, carbohydrates, calories, lightness,...
Climatic changes are leading to an increased number of flooding year by which impacts negatively the metabolism roots and influences shoot leads a decline in soybean productivity. This can be more drastic when it is cultivated lowland soils. Our group hypothesized that tolerant sister-line plants have capacity cope with oxidative stress due better management energy use dissipation on photosynthesis machinery during root-flooding recovery conditions, while sensitive impairment photosynthetic...
Plant electrophysiology has unveiled the involvement of electrical signals in physiology and behavior plants. Spontaneously generated bioelectric activity can be altered response to changes environmental conditions, suggesting that a plant's electrome may possess distinct signature associated with various stimuli. Analyzing signals, particularly electrome, conjunction Machine Learning (ML) techniques emerged as promising approach classify characteristic corresponding each stimulus. This...
The physiological processes underlying fruit ripening can lead to different electrical signatures at each stage, making it possible classify tomato through the analysis of signals. Here, activity ( Solanum lycopersicum var. cerasiforme) during was investigated as tissue voltage variations, and Machine Learning (ML) techniques were used for classification stages. Tomato harvested mature green stage placed in a Faraday's cage under laboratory-controlled conditions. Two electrodes per inserted...
Abstract Brazil presents a great variety of native fruits, which have aroused commercial interest, such as the strawberry guava. In this sense, many researches looked for alternatives that allow postharvest availability considering perishability is limiting factor its commercialization. The freezing process an important alternative in sense making these fruits available longer on market. use L-ascorbic acid potent protective agent stability bioactive compounds fruit pulps. objective study...
Do living beings need brains to do extraordinary things? The human brain manages many tasks at the same time, from keeping body working thinking and dreaming, thanks electrical signals it produces. But what about organisms that survive pretty well without brains, like plants? You might be surprised learn plants can produce electricity as well, they use for communication, learning, self-preservation, a rapid alarm system against potential threats. All this any cells! With scientific...
Blackberry (Rubus fruticosus L.), butiá (Butia spp.), and red pitanga (Eugenia uniflora L.) are rich in potentially bioactive compounds, such as phenolic which unstable to food processing conditions. The aim of this study was encapsulate blackberry juice through complex coacervation, using carrageenan, tragacanth, xanthan associated with pea protein, addition characterizing the particles evaluating profile release vitro after its application diet chewable candies blended pulp. following...

There is a trend towards the consumption of plant foods, especially from public that aims to reduce meat consumption. Plant-based food diets may have low source vitamin B12 as plants do not produce them. A possible alternative mitigate this fermented vegetables and fruits. Therefore, we aimed provide an overview work being done with fruits, show evidence it obtain necessary daily amount for human health maintenance. Vitamin B12, also known cobalamin, acts cofactor enzyme methionine synthase...
