The stress kinase gene MtSK1 in Medicago truncatula with particular reference to somatic embryogenesis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Medicago truncatula, a model for legume genomics, can be regenerated by somatic embryogensis by the use of a suitable genotype and an auxin plus cytokinin. The stress response induced by explant wounding and culture is increasingly recognized as an important component of somatic embryo induction. We have cloned and investigated the stress kinase gene MtSK1 in relation to somatic embryogenesis in M. truncatula, using the highly embryogenic mutant Jemalong 2HA (2HA) and its progenitor Jemalong. The main features of the MtSK1 protein of 351 amino acids are an N-terminal kinase domain and a C-terminal glutamic acid-rich region, which is predicted to be a coiled-coil. MtSK1 is a member of the SnRK2 subgroup of the SnRK group of plant kinases. Members of the SnRK2 kinases play a role in stress responses of plants. MtSKI expression is induced by wounding in the cultured tissue independent of auxin or cytokinin. However, in both 2HA and Jemalong, as the callus develops in response to auxin plus cytokinin, MtSK1 expression continues to increase. MtSK1 responds to salt stress in vivo, consistent with its role as a stress kinase. The likely role of MtSK1 in stress-induced signaling will facilitate the relating of stress-response pathways to auxin and cytokinin-induced signaling in the understanding of the molecular mechanisms involved in the induction of somatic embryogenesis in M. truncatula.
