Speaking at the Stress Tolerant Maize for Africa (STMA) project annual meeting yesterday in Harare, Lands, Agriculture and Rural Resettlement minister, Perrance Shiri said climate change has brough

The DREB (dehydration-responsive element binding)-type transcription factors are classified into six subgroups, named A-1 to A-6. The members of DREB A-1 and A-2 subgroups have been reported to be involved in response to various abiotic stresses. However, there were only a few genes belonging to A-3 to A-6 subgroups to be reported. In this study, we cloned a DREB A-4 subgroup gene from maize (Zea mays), ZmDREB4.1, and analyzed its characteristics and functions. ZmDREB4.1 was expressed in roots, stems, and leaves at very low levels. It was not induced by any biotic or abiotic treatment.

Drought is one of the major abiotic stresses affecting world agriculture. Breeding drought-resistant crops is one of the most important challenges for plant biologists. PYR1/PYL/RCARs, which encode the abscisic acid (ABA) receptors, play pivotal roles in ABA signaling, but how these genes function in crop drought response remains largely unknown. Here we identified 13 PYL family members in maize (ZmPYL1-13). Changes in expression of these genes under different stresses indicated that ZmPYLs played important roles in responding to multiple abiotic stresses.

Efforts have been made in recent years to improve knowledge about soil greenhouse gas (GHG) fluxes from subSaharan Africa. However, data on soil GHG emissions from smallholder coffee-dairy systems have not hitherto been measured experimentally. This study aimed to quantify soil GHG emissions at different spatial and temporal scales in smallholder coffee-dairy farms in Murang'a County, Central Kenya.

Cereal farmers in Rwanda have been warned to remain alert for a resurgence of the fall armyworm invasion.

Arusha — Armyworms and pernicious weeds are threatening crops in Arusha.

It is feared that they will cause a food shortage.

Farmers in Cameroon struggling with the effects of prolonged drought are finding relief through a government-supported initiative to give them access to better crop seeds.

A plague of fall army-worm that has spread to all the country's provinces has infested nearly 150 000 hectares posing a serious threat to the country's major staple food crop -- maize, preliminary

Fall armyworm,Spodoptera frugiperda(J E Smith), an economically important pest native to tropical and sub-tropical America has recently invaded Africa, causing substantial damage to maize and other crops. We eval-uated functionality of a companion cropping system,‘climate-adapted push-pull’, developed for control of cereals

India has among the highest lost years of life from micronutrient deficiencies. We investigate what dietary shifts would eliminate protein, iron, zinc and Vitamin A deficiencies within households’ food budgets and whether these shifts would be compatible with mitigating climate change. This analysis uses the National Sample Survey (2011–12) of consumption expenditure to calculate calorie, protein and the above micronutrient intake deficiencies and relate them to diets, income and location.
