Cold resistance in plants: A mystery unresolved
Herbaceous temperate plants are capable of developing freezing tolerance when they are exposed to low nonfreezing temperatures. Acquired freezing tolerance involves extensive reprogramming of gene expression and metabolism. Recent full-genome transcript profiling studies, in combination with mutational and transgenic plant analyses, have provided a snapshot of the complex transcriptional networ...
متن کاملPost kala-azar dermal leishmaniasis: an unresolved mystery
Post kala-azar dermal leishmaniasis (PKDL), a cutaneous sequela of visceral leishmaniasis (VL), develops in some patients alongside but more commonly after apparent cure from VL. In view of the pivotal role of PKDL patients in the transmission of VL, here we review clinical, epidemiological, parasitological, and immunological perspectives of this disease, focusing on five hypotheses to explain ...
متن کاملPlants in a cold climate.
Plants are able to survive prolonged exposure to sub-zero temperatures; this ability is enhanced by pre-exposure to low, but above-zero temperatures. This process, known as cold acclimation, is briefly reviewed from the perception of cold, through transduction of the low-temperature signal to functional analysis of cold-induced gene products. The stresses that freezing of apoplastic water impos...
متن کاملTRPA1 and Cold Transduction: An Unresolved Issue?
TRPA1 was originally characterized as a cold-activated ion channel; however, since the initial description there has been some disagreement about its role in cold sensation. Here, we review the literature on the function of TRPA1 as a cold sensor. Many studies have demonstrated that TRPA1 can be activated by cold when expressed in heterologous systems, but its role as a cold sensor in native pe...
متن کاملCold Signaling and Cold Response in Plants
Plants are constantly exposed to a variety of environmental stresses. Freezing or extremely low temperature constitutes a key factor influencing plant growth, development and crop productivity. Plants have evolved a mechanism to enhance tolerance to freezing during exposure to periods of low, but non-freezing temperatures. This phenomenon is called cold acclimation. During cold acclimation, pla...
