A high-throughput protocol for testing heat-stress tolerance in pollen.

Unlabelled: Viable pollen is crucial for fertilization, but pollen is generally highly susceptible to heat stress. A quick, reliable method for testing the heat-stress tolerance of pollen is needed to improve the heat-stress tolerance in plants, but current methods require considerable space and labor. In addition, many such methods only test tolerance to a single constant temperature, making it time-consuming to screen heat tolerance over a wide temperature range and to examine the dynamics of pollen viability at different temperatures.

The Geometric Series Hypothesis of Leaf Area Distribution and Its Link to the Calculation of the Total Leaf Area per Shoot of 'Aureostriatus'.

Total leaf area per shoot () can reflect the photosynthetic capacity of a shoot. A prior study hypothesized that is proportional to the product of the sum of the individual leaf widths per shoot () and the maximum individual leaf length per shoot (), referred to as the Montgomery-Koyama-Smith equation (MKSE). However, empirical evidence does not support such a proportional relationship hypothesis, as was found to allometrically scale with , i.

Comparative analysis of zinc, copper, cadmium, and arsenic accumulation in forage-grain rice: Implications for food safety and health risks.

Forage-grain ratoon rice (FG-RR) systems, integrating grain and forage production, promise a sustainable approach to enhance food security and livestock development in marginal regions where ratoon rice (T-RR) is traditionally cultivated. Here, we quantified zinc (Zn), copper (Cu), arsenic (As), and cadmium (Cd) concentrations in ratoon crop grains from 23 rice varieties at four mowing stages (heading, milk-ripening, dry-ripening, and full maturity) of the main crop. Early mowing at the milk-ripening stage significantly reduced As levels (16.

Effect of sorghum flour-containing pasta on postprandial glycemia, appetite and energy intake in healthy individuals.

Background/objectives: In vitro studies suggest that incorporating sorghum flour into staple foods including pasta reduces their starch digestibility and hence may suppress postprandial blood glucose levels, appetite and energy intake; however, these effects in humans have yet to be reported. Therefore, this study investigated the effect of red and white sorghum-containing pasta on blood glucose response, appetite and energy intake in humans.

Subjects/methods: In a randomised crossover design, healthy individuals (n = 20) consumed the following three iso-caloric test meals (each providing 50 g available carbohydrates) as breakfast: control pasta (CP) made from100% durum wheat; 30% red sorghum pasta (RSP) and; 30% white sorghum pasta (WSP).

The Effects of Fat Content on the Shelf-Life of Vacuum-Packed Red Meat.

When stored at chill temperatures, vacuum-packed (VP) lamb has a much shorter shelf-life than VP beef, primarily due to its higher pH, which could be linked to the higher fat content. The higher pH would create more favourable conditions for the growth of spoilage bacteria, resulting in a shorter shelf-life of meat. To determine the effects of fat on meat shelf-life as it relates to pH, a series of shelf-life trials at 2 °C were conducted using VP beef and lamb mince with varying fat contents (i.

Electronic tongue measurements as a predictor for sensory properties of vacuum-packed minced beef - A preliminary study.

Changes in meat sensory quality during storage are difficult to assess accurately and objectively. Advanced analytical technologies for sensory assessment could help predict sensory changes. In this study, vacuum-packed (VP) minced beef was incubated at four different temperatures until the end of its quality shelf-life, before conducting instrumental taste analysis with an Insent electronic tongue and analysis of volatile compounds with headspace SPME GC-MS.

Homocysteine S-Methyltransferase 3 Positively Regulates Cadmium Tolerance in Maize.

The increasing contamination of agricultural soils with cadmium (Cd) poses a significant threat to human health and global food security. Plants initiate a series of mechanisms to reduce Cd toxicity. However, the response of maize to Cd toxicity remains poorly understood.

Investigating environmental and geographical factors affecting iodine concentrations in Australian wheat (Triticum aestivum L.) grain.

Iodine is an essential micronutrient for human nutrition, though it is found in relatively low concentrations in many important crop species. Wheat (Triticum aestivum L.) is a common staple crop worldwide, and as such could be an important source of dietary iodine due to its widespread consumption.

qTaHa-5DL: another major QTL regulating wheat grain hardness.

Grain hardness has important effects on grain quality and the end-use of wheat. In this study, a collection of 103 common wheat germplasms and a DH population of 194 lines were used to identify new quantitative trait loci (QTL) for grain hardness. Two stable genetic loci on chromosome 5D were detected under different locations and years with one of them being the Ha locus on 5DS where the major gene Puroindolines for wheat grain hardness is located.

Comparison of four light-response models using relative curvature measures of nonlinearity.

Photosynthetic light response curves serve as powerful mathematical tools for quantitatively describing the rate of photosynthesis of plants in response to changes in irradiance. However, in practical applications, the daunting task of selecting an appropriate nonlinear model to accurately fit these curves persists as a significant challenge. Thus, there arises a need for a method to systematically evaluate the efficacy of such models.
