Cryptochrome 1a influences source-sink partitioning during different stages of growth in tomato
(2019-06-15)
Cryptochromes are photoreceptors that coordinate multiple processes during the plant life cycle through UV-A/blue light. In the present study, we used tomato cry1a mutant to understand how LeCRY1a influences the vegetative ...
A fast exploration of very deep soil layers by Eucalyptus seedlings and clones in Brazil
(Elsevier B.V., 2016-04-15)
Although pioneer studies showed several decades ago that deep rooting is common in tropical forests, direct measurements of fine root distributions over the entire soil profile explored by the roots are still scarce. Our ...
Trait similarity among dominant highly-competitive species rather than diversity increases productivity in semi-arid Mediterranean forests
(Elsevier Science, 2021-04)
Biodiversity plays a pivotal role in forest productivity and, through it, on the provision of ecosystem services. Consequently, understanding the mechanisms by which biodiversity drives productivity is a challenge for ...
Secondary xylem of stem and root of cerrado woody plants: anatomical and functional approach
(Universidade Estadual Paulista (Unesp), 2021-10-08)
The plant's ability to invest in the wood tissue in different organs is crucial to its survival in terrestrial environments. Wood is a complex system linked to water transport, mechanical support, and storage of essential ...
Directional, stabilizing, and disruptive trait selection as alternative mechanisms for plant community assembly
(Ecological Society of America, 2017-03-30)
How plant functional traits (e.g., seed mass) drive species abundance within communities remains an unsolved question. Borrowing concepts from natural selection theory, we propose that trait-abundance relationships can ...
Root Traits Associated with Nutrient Exploitation Following Defoliation in Three Coexisting Perennial Grasses in a Semi-Arid Savanna
(Wiley Blackwell Publishing, Inc, 2001-12)
Experiments were conducted to evaluate root traits associated with nutrient exploitation following defoliation in three coexisting perennial grasses in a semi-arid savanna. Root length density was determined within soil ...
Looking at the forest from below: the role of seedling root traits in the adaptation to climate change of two Nothofagus species in Argentina
(Springer, 2018-09)
Global climate change (CC) is an evolutionary challenge for natural tree populations. Scientific experts forecast an increase in temperature and a decrease in precipitation in the Argentine Patagonian Cordillera. Knowledge ...
