RNase T2 genes from rice and the evolution of secretory ribonucleases in plants.

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
The plant RNase T2 family is divided into two different subfamilies. S-RNases are involved in rejection of self-pollen during the establishment of self-incompatibility in three plant families. S-like RNases, on the other hand, are not involved in self-incompatibility, and although gene expression studies point to a role in plant defense and phosphate recycling, their biological roles are less well understood. Although S-RNases have been subjects of many phylogenetic studies, few have included an extensive analysis of S-like RNases, and genome-wide analyses to determine the number of S-like RNases in fully sequenced plant genomes are missing. We characterized the eight RNase T2 genes present in the Oryza sativa genome; and we also identified the full complement of RNase T2 genes present in other fully sequenced plant genomes. Phylogenetics and gene expression analyses identified two classes among the S-like RNase subfamily. Class I genes show tissue specificity and stress regulation. Inactivation of RNase activity has occurred repeatedly throughout evolution. On the other hand, Class II seems to have conserved more ancestral characteristics; and, unlike other S-like RNases, genes in this class are conserved in all plant species analyzed and most are constitutively expressed. Our results suggest that gene duplication resulted in high diversification of Class I genes. Many of these genes are differentially expressed in response to stress, and we propose that protein characteristics, such as the increase in basic residues can have a defense role independent of RNase activity. On the other hand, constitutive expression and phylogenetic conservation suggest that Class II S-like RNases may have a housekeeping role.
