Thanks for that - lots of interesting studies there, the one on blossom drop caught my eye right away.

The potassium study is interesting. Thanks for these links! Good winter reading, indeed.

Bhn seeds headquarters and testing is in the area.I am trying the bhn 624 this year myself.Thanx for links.

Dar,
Any way to keep this bumped up so I don't forget it or lose it? I have to finish a few books before I start this. Looking forward to the latest W.E.B Griffith novel right now. Ted |

Not as technical as some posted above and also a few years old:

[B]Abstract[/B] Glandular secreting trichomes on the surface of tomato plants and many of its relatives in the Solanaceae produce a mixture of [I]O[/I]-acyl sugars that contribute to insect resistance. The majority of acyl sucroses produced by the cultivated tomato ([I]Solanum lycopersicum[/I]) contain three or four short chain aliphatic acyl esters, and tetra-acyl sucroses have an acetyl group as one of the acyl chains. We previously reported overlapping [I]S. lycopersicum[/I] × [I]Solanum pennellii[/I] introgression lines (ILs) that fail to accumulate high levels of acetylated tetra-acyl sucroses. A survey of the annotated genes in this region of cultivated tomato chromosome 1 revealed three candidate acyltransferases that were tested for function using virus-induced gene silencing. A member of the BAHD family of acyltransferases (Solyc01g105580, [I]SlAT2[/I]) was shown to encode an acetyl-CoA–dependent acyltransferase enzyme capable of acyl sucrose acetylation in vitro. RNAi suppression of [I]SlAT2[/I] in transgenic [I]S. lycopersicum[/I] cv. M82 resulted in reduced acyl sugar acetylation, whereas expression of the functional [I]S. lycopersicum[/I] allele of [I]SlAT2[/I] in the triacyl sucrose producing IL1-3 restored the ability of the IL to synthesize acetylated tetra-acyl sugars. Transgenic plants with the [I]SlAT2[/I] promoter driving GFP expression showed fluorescence in tips cells of long, slender trichomes that is consistent with acyl sugar acetylation occurring in these cells. [B][URL="http://www.plantphysiol.org/content/160/4/1854.full"][SIZE=2]Striking Natural Diversity in Glandular Trichome Acylsugar Composition Is Shaped by Variation at the Acyltransferase2 Locus in the Wild Tomato [I]Solanum habrochaites[/I][/SIZE][/URL][/B] [B]Abstract[/B] Acylsugars are polyesters of short- to medium-length acyl chains on sucrose or glucose backbones that are produced in secretory glandular trichomes of many solanaceous plants, including cultivated tomato ([I]Solanum lycopersicum[/I]). Despite their roles in biotic stress adaptation and their wide taxonomic distribution, there is relatively little information about the diversity of these compounds and the genes responsible for their biosynthesis. In this study, acylsugar diversity was assessed for 80 accessions of the wild tomato species [I]Solanum habrochaites[/I] from throughout the Andes Mountains. Trichome metabolites were analyzed by liquid chromatography-time of flight-mass spectrometry, revealing the presence of at least 34 structurally diverse acylsucroses and two acylglucoses. Distinct phenotypic classes were discovered that varied based on the presence of glucose or sucrose, the numbers and lengths of acyl chains, and the relative total amounts of acylsugars. The presence or absence of an acetyl chain on the acylsucrose hexose ring caused clustering of the accessions into two main groups. Analysis of the [I]Acyltransferase2[/I] gene (the apparent ortholog of Solyc01g105580) revealed differences in enzyme activity and gene expression correlated with polymorphism in [I]S. habrochaites[/I] accessions that varied in acylsucrose acetylation. These results are consistent with the hypothesis that glandular trichome acylsugar acetylation is under selective pressure in some populations of [I]S. habrochaites[/I] and that the gene mutates to inactivity in the absence of selection. |
