As global land surface temperature continues to rise and heatwave events increase in
frequency, duration, and/or intensity, our key food and fuel cropping systems will likely face …

Drought is a major environmental stress threatening wheat productivity worldwide. Global
climate models predict changed precipitation patterns with frequent episodes of drought …

Between the 1930s and 50s, evolutionary biologists developed a successful theory of why
organisms age, firmly rooted in population genetic principles. By the 1980s the evolution of …

Senescence is a developmental process which in annual crop plants overlaps with the
reproductive phase. Senescence might reduce crop yield when it is induced prematurely …

Michael G. Ryan and Barbara J. Yoder y do old trees stop grow-/ing in height? Trees seem
to have mechanisms that slow their growth as they age and prevent them from growing …

This unique book looks at the biology of aging from a fundamentally new perspective, one
based on evolutionary theory rather than traditional concepts which emphasize molecular …

Oxidative stress is commonly induced when plants are grown under high temperature (HT)
stress conditions. Selenium often acts as an antioxidant in plants; however, its role under HT …

Monocarpic plants require the initiation of whole‐plant senescence to remobilize and
transfer assimilates pre‐stored in vegetative tissues to grains. Delayed whole‐plant …

Publisher Summary This chapter reviews the evidence for the pattern of growth decline with
age and discusses the evidence for the mechanisms that may be responsible. It begins with …

Senescence is a highly organized and well‐regulated process. As much as 75% of total
cellular nitrogen may be located in mesophyll chloroplasts of C3‐plants. Proteolysis of …
