Physiological responses of rosewoods and under drought and heat stresses.

and are classified as vulnerable and endangered, respectively, in the IUCN Red List and under continued threat from deforestation and illegal harvesting for rosewood. Despite emerging efforts to conserve and restore these species, little is known of their responses to drought and heat stress, which are expected to increase in the Greater Mekong Subregion where the species co-occur and are endemic. In this study of isolated and combined drought and heat effects, we found that had an earlier stomatal closure and more constant midday water potential in response to increasing drought level, suggesting that is relatively isohydric while is relatively anisohydric.

Mechanisms of immunization against cancer using chimeric antigens.

Successful approaches to tumor immunotherapy must overcome the physiological state of tolerance of the immune system to self-tumor antigens. Immunization with appropriate variants of syngeneic antigens can achieve this. However, improvements in vaccine design are needed for efficient cancer immunotherapy.
