Can a maize price band work in Malawi? por Baulch, Bob, Botha, Rosemary

“…To defend a set floor price, ADMARC would need to buy off any excess supply on the market, thereby creating an upward pressure on maize prices. Conversely, to ensure the ceiling prices are not exceeded, the NFRA would need to release maize for ADMARC to sell on the market to create a downward pressure and bring the prices down to the ceiling price. …”

Knockdown of glycine decarboxylase complex alters photorespiratory carbon isotope fractionation in Oryza sativa leaves por Giuliani, Rita, Karki, Shanta, Covshoff, Sarah, Lin, Hsiang-Chun, Coe, Robert A., Koteyeva, Nuria K., Quick, W. Paul, von Caemmerer, Susanne, Furbank, Robert T., Hibberd, Julian M., Edwards, Gerald E., Cousins, Asaph B.

“…Leaf measurements on transgenic gdch knockdown and wild-type plants were carried out in the light under photorespiratory and low photorespiratory conditions (i.e. 18.4 kPa and 1.84 kPa atmospheric O-2 partial pressure, respectively), and in the dark. Under approximately current ambient O-2 partial pressure (18.4 kPa pO(2)), the gdch knockdown plants showed an expected photorespiratory-deficient phenotype, with lower leaf net CO2 assimilation rates (A) than the wild-type. …”

Characterization of SARS-CoV-2 intrahost genetic evolution in vaccinated and non-vaccinated patients from the Kenyan population por Lugano, Doreen, Mwangi, Kennedy, Mware, Bernard, Kibet, Gilbert, Osiany, Shebbar, Kiritu, Edward, Dobi, Paul, Muli, Collins, Njeru, Regina, Oliveira, T. de, Njenga, M.K., Routh, A., Oyola, Samuel O.

“…However, vaccination can affect the evolution and adaptation of SARS-CoV-2 largely through vaccine-induced immune pressure. Here, we investigated intrahost recombination and single nucleotide variations (iSNVs) on the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome in non-vaccinated and vaccinated sequences from the Kenyan population to profile intrahost viral genetic evolution and adaptations driven by vaccine-induced immune pressure. …”
