Abstract:
... ADP‐ribosylation factors (ARFs) are small GTP‐binding proteins that regulate a wide variety of cell functions. Previously, we isolated a new ARF, ZmArf2, from maize (Zea mays). Sequence and expression characteristics indicated that ZmArf2 might play a critical role in the early stages of endosperm development. In this study, we investigated ZmArf2 function by analysis of its GTP‐binding activity a ...

Abstract:
... Hypocotyl elongation in the dark is a crucial process to ensure seedling emergence. It relies both on the cell number and cell length. The contribution of these two factors to the maximal hypocotyl length and the impact of environmental conditions on this contribution are not known. This is surprising considering the agronomic and economical importance of seedling emergence in crop establishment. ...

Subject:
Arabidopsis; buffers; chlorophyll; gel electrophoresis; glass; grinding; phosphorylation; photosynthesis; protein content; thylakoids
Abstract:
... Robust and reproducible methods for extracting thylakoid membranes are required for the analysis of photosynthetic processes in higher plants such as Arabidopsis. Here, we compare three methods for thylakoid extraction using two different buffers. Method I involves homogenizing the plant material with a metal/glass blender; method II involves manually grinding the plant material in ice‐cold grindi ...

Abstract:
... The gene expression chip of a salt‐tolerant wheat mutant under salt stress was used to clone a salt‐induced gene with unknown functions. This gene was designated as TaSR (Triticum aestivum salt‐response gene) and submitted to GenBank under accession number EF580107. Quantitative polymerase chain reaction (PCR) analysis showed that gene expression was induced by salt stress. Arabidopsis and rice (O ...

Abstract:
... Although physiological effects of acute flooding have been well studied, chronic effects of suboptimal soil aeration caused by over‐irrigation of containerized plants have not, despite its likely commercial significance. By automatically scheduling irrigation according to soil moisture thresholds, effects of over‐irrigation on soil properties (oxygen concentration, temperature and moisture), leaf ...

Abstract:
... Browning phenomena are ubiquitous in plant cell cultures that severely hamper scientific research and widespread application of plant cell cultures. Up to now, this problem still has not been well controlled due to the unclear browning mechanisms in plant cell cultures. In this paper, the mechanisms were investigated using two typical materials with severe browning phenomena, Taxus chinensis and G ...

Abstract:
... Plants with the crassulacean acid metabolism (CAM) express high‐metabolic plasticity, to adjust to environmental stresses. This article hypothesizes that irradiance and nocturnal temperatures are the major limitations for CAM at higher latitudes such as the Azores (37°45'N). Circadian CAM expression in Ananas comosus L. Merr. (pineapple) was assessed by the diurnal pattern of leaf carbon fixation ...

Abstract:
... Soil water deficits applied at different rates and for different durations can decrease both stomatal conductance (gₛ) and leaf water potential (Ψₗₑₐf). Understanding the physiological mechanisms regulating these responses is important in sustainable irrigation scheduling. Glasshouse‐grown, containerized Pelargonium × hortorum BullsEye plants were irrigated either daily at various fractions of pla ...

Abstract:
... Preexposure to a stress could induce stable signals and reactions on plant physiology and gene expression during future encounters as a ‘stress memory’. In this study, we found that two trainable genes, BPSP encoding putative brown plant hopper susceptibility protein and sucs encoding sucrose synthase displayed transcriptional memory for their considerably higher transcript levels during two or mo ...
