The rice genome encodes two vacuolar invertases with fructan exohydrolase activity but lacks the related fructan biosynthesis genes of the Pooideae The rice genome encodes two vacuolar invertases with fructan exohydrolase activity but lacks the related fructan biosynthesis genes of the Pooideae

Ji XM, Van den Ende W, Schroeven L, Clerens S, Geuten K, Cheng SH and Bennett J (2007). The rice genome encodes two vacuolar invertases with fructan exohydrolase activity but lacks the related fructan biosynthesis genes of the Pooideae. New Phytologist 173:50–62 (DOI: 10.1111/j.1469-8137.2006.01896.x).

Fructans are believed to contribute to cold and drought tolerance in several plant families (Poaceae, Asparagaceae and Asteraceae), but it is not clear why the ability to accumulate these polymers is found in some genera (e.g. Triticum) but not in others (e.g. Oryza). As fructan biosynthesis enzymes (FBEs) evolved from vacuolar invertases (VINs), we searched the rice genome sequence for genes related to both FBE and VIN genes of wheat and other members of the Pooideae. We compared them at the levels of exon–intron structure, protein sequence, and the enzymatic properties of recombinant proteins after expression in the yeast
Pichia pastoris.

Marker-assisted selection to improve drought adaptation in maize: the backcross approach, perspectives, limitations, and alternatives Marker-assisted selection to improve drought adaptation in maize: the backcross approach, perspectives, limitations, and alternatives

Ribaut J-M and Ragot M (2007). Marker-assisted selection to improve drought adaptation in maize: the backcross approach, perspectives, limitations, and alternatives. Journal of Experimental Botany 58(2):351–360. (DOI: 10.1007/s11032-006-9041-2).

A number of different marker-assisted selection (MAS) approaches do exist for the improvement of polygenic traits. Results of a marker-assisted backcross (MABC) selection experiment aimed at improving grain yield under drought conditions in tropical maize are presented and compared with alternative MAS strategies. The introgression of favourable alleles at five target regions involved in the expression of yield components and flowering traits increased grain yield and reduced the asynchrony between male and female flowering under water-limited conditions.

Welcker C, Boussuge B, Bencivenni C, Ribaut J-M and Tardieu F (2007). Are source and sinks strengths genetically linked in maize plants subjected to water deficit? A QTL study of the responses of leaf growth and Anthesis-Silking Interval to water deficit. Journal of Experimental Botany 58(2):339–349. (DOI: 10.1093/jxb/erl227).

Leaf growth and Anthesis–Silking Interval (ASI) are the main determinants of source and sink strengths of maize via their relations with light interception and yield, respectively. They depend on the abilities of leaves and silks to expand under fluctuating environmental conditions, so the possibility is raised that they may have a partly common genetic determinism. This possibility was tested in a mapping population which segregates for ASI. Maximum leaf elongation rate per unit thermal time (parameter a) and the slopes of its responses to evaporative demand and soil water status (parameters b and c) were measured in greenhouse and growth chamber experiments, in two series of 120 recombinant inbred lines (RILs) studied in 2004 and 2005 with 33 RILs in common both years.

Leaf growth rate per unit thermal time follows QTL-dependent daily patterns in hundreds of maize lines under naturally fluctuating condition Leaf growth rate per unit thermal time follows QTL-dependent daily patterns in hundreds of maize lines under naturally fluctuating condition

Sadok W, Naudin Ph, Boussuge B, Muller B, Welcker C and Tardieu F (2007). Leaf growth rate per unit thermal time follows QTL-dependent daily patterns in hundreds of maize lines under naturally fluctuating conditions. Plant, Cell & Environment 30(2):135–146. (DOI: 10.1111/j.1365-3040.2006.01611.x).

We have analysed daily patterns of leaf elongation rate (LER) in large data sets with 318 genotypes placed in naturally fluctuating temperature and evaporative demand, and examined the effect of targeted alleles on these patterns. The method consisted, firstly, in expressing elongation rate per unit thermal time, so it became temperature independent; secondly, in a joint analysis of diurnal fluctuations of elongation rate and of micrometeorological conditions in several experiments, and finally, in a comparison of daily patterns between groups of genotypes possessing targeted alleles.
