Evidence is accumulating that root system collapse is involved with HLB-induced tree decline, especially with commercial sweet orange and grapefruit trees on Swingle and Carrizo. Maintaining root health is imperative for keeping trees productive in an HLB endemic environment. In an effort to improve tree health by focusing on the roots, we have been experimenting …

The biological mechanism behind this winter recovery has been studied but is not fully resolved
A one percentage point increase in the unemployment rate raised the probability of receiving a bonus by 0.9 percentage points.We conducted five robustness checks. first, we estimated all three equations separately for documented and undocumented workers. That is, we allowed all the coefficients to vary between these two groups instead of only the recession dummies. …
SBP and TCP TFs are known to be plant-specific developmental regulators
Transcription factors act as master switches of transcriptional reprogramming, inducing diverse protective mechanisms in response to abiotic stresses.We identified a large number of TFs responsive to dehydration, and 287 TFs were responsive to rehydration from among the DTGs . Among these TFs, the bHLH, MYB, and WRKY families were the largest groups during both dehydration and rehydration …

We found that the auxin response pathway certainly does change during development
Environmental cues, especially temperature and light, have huge impacts on organ abscission. It has been reported in various plant species that high temperature accelerates reproductive organ abscission. In cotton, day temperatures above 40 °C can induce flower abscission. In soybean, flower abscission was found to increase with the elevated temperature treatment in three different soybean varieties, while …

All Verticillium-resistance evaluations were conducted following root-dip inoculations
Benefit transfer approaches, SFA, and DEA yield results that can evaluate how well an NTS site is performing and how to improve their functioning, but have associated advantages and disadvantages . Benefit transfer approaches can provide an estimate for ecosystem services value, which can be used in cost-benefit analyses to determine net changes to well-being. …
Export crops must also be carefully graded and presented according to exact specifications
Assuming all of the roughly 16 000 smallholder farmers currently growing tobacco were to produce an average of 400kg of paprika, for example, this would result in a total yield of just 6 400 tons, equal to less than half of Zimbabwe’s record crop. Although it is not unreasonable to expect this could lead to …
Large-scale commercial farmers occupy almost 63% of this high potential farmland
Zimbabwe exports most of her tobacco crop, however, so if global demand for tobacco were to fall in future , the impact on employment would depend on the extent to which commercial farmers were able to switch to other export crops such as roses, paprika, coffee and vegetables which are also highly labor intensive. Many …

Several patterns emerge when we consider all of the expression data analyzed
The homolog of Arabidopsis TCP4, AqTCP4, was expressed at fairly consistent levels across all stages in the spurred taxa, but showed a substantial increase in expression in A. ecalcarata at DS3 and DS4, while AqTCP5 showed a gradual decrease in expression across all taxa, but a slightly higher level of expression in A. ecalcarata.Aquilegia has …

Preservation method can have significant effects on downstream options
As more sampling is completed, e.g. baseline surveys and during pilot mining programs, there will be an opportunity to build a database for genetic information that can be linked to specific species. Accomplishing this aim may require a combined approach.Benthic organisms can be classified by size: megafauna , macrofauna , meiofauna , and microbial communities. …

It is tricky to evaluate the effects of the shift to maize on Native American health
Assessing the central nutritional role of indigenous agriculture alongside that of hunting and gathering might well suggest that malnutrition, rather than simply the spread of diseases through concentrated settlement, made communities less likely to recover from infectious epidemics. According to Snow, had “European expansion been less rapid, and had lethal epidemics not swept the landscape …
