Tradeoffs between productivity and nitrogen conservation in wild and domesticated plants of the perennial crop Physaria (Brassicaceae)
(Wiley Blackwell Publishing, Inc, 2018-09)
Domestication of desert-adapted perennials has been proposed as an alternative to increase cropping intensity in low input environments. However, selection for high yield in perennial crops provokes indirect changes in ...
The growth rate modulates time to first bud appearance in Physaria mendocina
(Elsevier, 2013-05)
Physaria mendocina is under domestication because its seeds contain significant amounts of hydroxy fatty acids for several industrial uses, but displays a facultative biennial behavior which may represent a drawback in ...

Carbon acquisition strategies uncoupled from predictions derivedfrom species life-cycle
(Elsevier Gmbh, 2015-03)
We compare carbon use strategies of congeneric annual (P. gracilis and P. angustifolia) and perennial (P. mendocina and P. pinetorum) Physaria (Brassicaceae), to evaluate the relevance of eco-physiological traits as ...
Relationship between photosynthetic rate, water use and leaf structure in desert annual and perennial forbs differing in their growth
(Springer, 2018-12)
Specific leaf area (SLA) is a key trait to screen plants for ecological performance and productivity; however, the relationship between SLA and photosynthesis is not always up-scalable to growth when comparing multiple ...

Back to perennials: Does selection enhance tradeoffs between yield and longevity?
(Elsevier Science, 2016-11)
Perennial plants allocate more resources belowground and have longer-lived leaves than their annual counterparts, which are the basis for the promotion of perennial crops towards a more sustainable agriculture. On the ...
Mechanisms of nitrogen conservation at the leaf-level in annual and perennial desert forbs: Implications for perennial crops domestication
(Elsevier Gmbh, 2019-03)
Perennial plants show traits such as long-lived leaves and higher nutrient retention that provide a more efficient use of nutrients in low-resource environments when compared to annuals. These traits do not only generate ...
Plasticity in nitrogen conservation strategy under C gain variation in annual and perennial Physaria (Brassicaceae)
(Elsevier Gmbh, 2020-09)
Perennial plants have a greater reliance on internal cycling of nitrogen and are less influenced by external fluctuations of soil fertility than annuals. Despite their importance, the major mechanisms in which annuals and ...
