Grain crops are a key driver of the current global phosphorus (P) cycle through their continued demand for P fertilizer, and the subsequent removal of P from fields in the harvested grain. Breeding crops that can yield well with fewer P inputs (i.e., P-efficient crops) may reduce the impact of grain crops of the P cycle, but to date breeding P-efficient cultivars has focused on enhancing P acquisition efficiency (PAE). While the literature abounds in reported genotypic differences in internal P utilization efficiency (PUE) across a range of crops, there has been little progress in breeding crop cultivars with high PUE. This review critically analyzes why drawing conclusions from the body of research on PUE over the past few decades remains difficult and how progress in breeding crop cultivars high in PUE has been impeded. Four aspects of research on PUE are highlighted as being critical in limiting our understanding and exploitation of PUE in grain crops: (i) poor definition of PUE and inconsistent use of terminology, (ii) inappropriate methods used in genotypic screening for PUE that fail to account for the confounding effects of PAE on PUE, (iii) inadequate discussion on the level of P stress suffered by plants and its influence on potential mechanisms conferring high PUE and their utility in cropping systems, and (iv) a focus on P-stress response mechanisms rather than mechanisms conferring genotypic P-tolerance when investigating PUE. These factors are discussed in detail and new approaches and future areas of research on PUE are proposed. © 2012 Elsevier Inc.

Drought negatively impacts plant growth and the productivity of crops around the world. Understanding the molecular mechanisms in the drought response is important for improvement of drought tolerance using molecular techniques. In plants, abscisic acid (ABA) is accumulated under osmotic stress conditions caused by drought, and has a key role in stress responses and tolerance. Comprehensive molecular analyses have shown that ABA regulates the expression of many genes under osmotic stress conditions, and the ABA-responsive element (ABRE) is the major cis-element for ABA-responsive gene expression. Transcription factors (TFs) are master regulators of gene expression. ABRE-binding protein and ABRE-binding factor TFs control gene expression in an ABA-dependent manner. SNF1-related protein kinases 2, group A 2C-type protein phosphatases, and ABA receptors were shown to control the ABA signaling pathway. ABA-independent signaling pathways such as dehydration-responsive element-binding protein TFs and NAC TFs are also involved in stress responses including drought, heat, and cold. Recent studies have suggested that there are interactions between the major ABA signaling pathway and other signaling factors in stress responses. The important roles of these TFs in crosstalk among abiotic stress responses will be discussed. Control of ABA or stress signaling factor expression can improve tolerance to environmental stresses. Recent studies using crops have shown that stress-specific overexpression of TFs improves drought tolerance and grain yield compared with controls in the field. © 2014 Nakashima, Yamaguchi-Shinozaki and Shinozaki.

A method for aligning proteins is provided. The method for aligning the proteins (20 and 32) is capable of aligning proteins (20 and 32) on the substrate (10) comprising carbon. The proteins (20 and 32) are used as structures comprising a cellulose binding domain (22) of the cellulosome and a cohesin domain (21), and a protein (30) to be bonded to the protein (20) is used as a protein (32) having a dockerin domain (31). The cohesin domain (21) can be used as an amino-acid sequence for a cohesin domain (21) derived from various microorganisms, and a functional protein can be used as a protein structure having a microbial-species-specific dockerin domain. The protein (20) can be arrayed regularly along a graphite hexagonal-plate-shaped crystal, and any protein (32) having this dockerin domain (20) can be bonded and arranged as an active protein (32) on the graphite (10).
