Project description:The expression of stress-related genes induced by feeding of chestnut moth larvae (Conistra vaccinii L.) was studied with Vitreoscilla hemoglobin-expressing (VHb) and non-transgenic hybrid aspen lines (Populus tremula x P. tremuloides). Besides the herbivore-injured leaves (L1), cDNA microarray analyses were conducted using uninjured leaves of hybrid aspen lines positioned above (A) and below (B) the herbivory exposed leaves.

Besides the herbivore-injured leaves (L1), cDNA microarray analyses were conducted using uninjured leaves of hybrid aspen lines positioned above (A) and below (B) the herbivory exposed leaves. Two-condition experiment, control vs. herbivory exposure. Two hybrid aspen lines: non-transgenic V617 and VHb expressing V617 /45. Of each plant, three leaf types were analysed: the injured/uninjured leaf (L1) and nonorthostichous leaf positioned above (A) and below (B). Biological replicates: 3. On each array, two samples representing L1, A or B leaf type of control and herbivory treatment of either V617 or V617/45 line. line V617: wt_A_rep1-3, wt_B_rep1-3, wt_L1_rep1-3 line V617/45: VHb_A_rep1-3, VHb_B_rep1-3, VHb_L1_rep1-3 leaf type A: wt_A_rep1-3, VHb_A_rep1-3 leaf type B: wt_B_rep1-3, VHb_B_rep1-4 leaf type L1: wt_L1_rep1-3, VHb_L1_rep1-5
Project description:In this study, the Chinese chestnut ‘Huaihuang’ was used to explore the possible mechanisms of ovule abortion with respect to proteomics. The chestnut anthesis starts mid-June. The development of the burs of C. mollissima cv. ‘Huaihuang’ were monitored from 15 to 25 days after anthesis (DAA) And the burs for different times were collected from the Chestnut Experiment Station in Huairou District, Beijing, China. This experiment was conducted at the Beijing Protein Innovation Co., Ltd.
