Welcome to LSD 3.0: Leaf Senescence Database Update!


As in other organisms, plants undergo age-dependent developmental changes during their lifespans. Leaves, the major photosynthetic organs, undergo growth, maturation, and senescence, and ultimately progress to death along age. As the last phase of leaf development, leaf senescence is a highly ordered process regulated by senescence associated genes (SAGs) and is tightly controlled by multiple layers of regulation, including at the level of chromatin and transcription, as well as by post-transcriptional, translational and post-translational regulation.

To facilitate the systematical research and comparative study of leaf senescence, we constructed a database of leaf senescence (LSD 1.0, August 2011; LSD 2.0, June 2013) to collect SAGs, mutants, phenotypes and literature references. Now, we update LSD to a new version LSD 3.0 (June 2019).



LSD 3.0 contains 5854 genes and 617 mutants. New features of LSD 3.0 are as follows:

. 564 genes and 293 mutants from 24 Species are added in LSD 3.0.
. Transcriptomics data of leaf senescence in Poplar are added.
. Senescence-differentially expressed small RNAs(Sen-smallRNA) in Arabidopsis are added.
. Interaction pairs between Sen-small RNA and Sen-TF are added.
. Senescence phenotypes of 90 natural accessions (ecotypes) and 42 images of ecotypes in Arabidopsis are added.
. Mutant seed information of SAGs in rice obtained from kitbase is integrated.
. New options of search engines for ecotypes and transcriptomics data are implemented.
