Tissue-specific expression and functional role of dehydrins in heat tolerance of sugarcane (Saccharum officinarum).

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
Studies on the functional roles of dehydrins (DHNs) in heat tolerance of plants are scarce. This study was conducted to immunohistolocalize DHNs in leaves of heat-tolerant (CP-4333) and heat-sensitive (HSF-240) sugarcane (Saccharum officinarum L.) clones at three phenological stages in order to elucidate their putative roles under heat stress. CP-4333 indicated greater amounts of heat-stable proteins than HSF-240 under heat stress. Western blotting revealed the expression of three DHNs in CP-4333 (13- and 15-kDa peptides at 48 h and an additional 18-kDa band at 72 h) and two (13 and 15 kDa at 48 h) in HSF-240 at formative stage; two DHNs in CP-4333 (20 and 25 kDa) and one in HSF-240 (20 kDa) at grand growth stage, while two DHNs in CP-4333 (20 and 22 kDa) and one in HSF-240 (20 kDa) at maturity stage. Tissue-specific immunohistolocalization showed that DHNs were expressed in stele particularly the phloem and the cells intervening bundle sheath and vascular bundles. Furthermore, DHNs were also found scattered along the epidermal and parenchymatous cells. Recovery of sugarcane from heat stress manifested a gradual disappearance of DHNs in both the clones, being quicker in sensitive clone (HSF-240). Results suggested specific implications for DHNs synthesis. Their synthesis in epidermis appears to protect the mesophyll tissues from heat injury. When associated to vascular tissue, they tend to ensure the normal photoassimilate loading into the sieve element-companion cell complex. DHNs diminution during recovery suggested that their expression was transitory. However, prolonged retention of DHNs by tolerant clone appears to be an adaptive advantage of sugarcane to withstand heat stress.
