In Arabidopsis (Arabidopsis thaliana), ethylene responses are mediated by a family of five receptors that have both overlapping and nonoverlapping roles. In this study, we used loss-of-function mutants for each receptor isoform to determine the role of individual isoforms in seed germination under salt stress. From this analysis, we found subfunctionalization of the receptors in the control of ...

Ten yearling steers weighing 270-360 kg died acutely after eating early seed pod stage Lupinus argenteus (silvery lupine) containing high levels of piperidine alkaloids, including ammodendrine and N-methylammodendrine. Reduced availability of Quality feed from range moderately depleted of Quality grasses appeared a major factor in causing the cattle to graze lupine. Proximate analysis of whole ...

Seed germination, seedling emergence and crop establishment are important aspects of canola production, and are the main components of seed/seedling vigour. A major concern of seed businesses and canola growers alike is loss of seed vigour that may go undetected before planting. Two vigour assays, based on off-gassing of ethyl alcohol from poor vigour seed, are being developed. They are a simpl...

Non-negative point-wise priors such as saliency map, defocus field, foreground mask, object location window, and user given seeds, appear in many fundamental computer vision problems. These priors come in the form of confidence or probability values, and they are often incomplete, irregular, and noisy, which eventually makes the labelling task a challenge. Our goal is to extract image regions t...

The relationship between equilibration injury and equilibration dependence of the transverse relaxation time (T2) measurements was examined using NMR in two different seed species (sensitive-soybean and tolerant-wheat) differing in their sensitivity to seed equilibration conditions. The T2 values of both seed species declined with high temperature (45 degrees C) and low RH (5.5-1%) and, also wi...

Determining how widespread human-induced changes such as habitat loss, landscape fragmentation, and climate instability affect populations, communities, and ecosystems is one of the most pressing environmental challenges. Critical to this challenge is understanding how these changes are affecting the movement abilities and dispersal trajectories of organisms and what role conservation planning ...

Seeds of carrot, groundnut, lettuce, oilseed rape and onion were stored hermetically in laminated aluminium foil packets in four environments (dry or ultra-dry moisture contents combined factorially with temperatures of 20°C or -20°C), replicated at several sites. After ten years’ hermetic storage, seed moisture content, equilibrium relative humidity, viability (assessed by ability to germinate...

The quality of edible seeds for human and animal nutrition is crucially dependent on high zinc (Zn) and iron (Fe) seed concentrations. The micronutrient bioavailability is strongly reduced by seed phytate that forms complexes with seed cations. Superior genotypes with increased seed Zn concentrations had been identified, but low micronutrient seed levels often prevail when the plants are grown ...

The famous Leftover Hash Lemma (LHL) states that (almost) universal hash functions are good randomness extractors. Despite its numerous applications, LHL-based extractors suffer from the following two limitations: – Large Entropy Loss: to extract v bits from distribution X of minentropy m which are ε-close to uniform, one must set v ≤ m − 2 log (1/ε), meaning that the entropy loss L def = m − v...
