Two types of thylakoid degradation are described, both including leaf bleaching (i.e. chlorophyll degradation) and destruction of the photosynthetic membranes. The first type of degradation is characterized by coiling of single thylakoids and by cup-shape stacking of grana thylakoids. This type of thylakoid degradation was observed in leaves of the aurea varieties (conditional mutants) of sever...
Erwinia tracheiphila is one of the most economically important pathogens of cucumbers, melons, squashes, pumpkins, and gourds in the northeastern and midwestern United States, yet its molecular pathology remains uninvestigated. Here, we report the first draft genome sequence of an E. tracheiphila strain isolated from an infected wild gourd (Cucurbita pepo subsp. texana) plant. The genome assemb...
به منظور بررسی تأثیر کاربرد زئولیت و محلولپاشی سلنیم در رژیمهای مختلف رطوبتی بر برخی صفات فیزیولوژیک و عملکرد دانۀ گیاه دارویی کدوی پوست کاغذی (cucurbita pepo l.)، آزمایشی به صورت فاکتوریل در قالب طرح بلوکهای کامل تصادفی با سه تکرار، در منطقۀ تاکستان واقع در استان قزوین طی سال 1389 به اجرا درآمد. عامل آبیاری در سه سطح شامل آبیاری معمول براساس 60 میلیمتر تبخیر از تشتک تبخیر کلاس a (شاهد)، ...
Hybridization between crops and their weedy or wild relatives is an area of concern because the widespread use of genetically engineered crops may allow novel, bene®cial transgenes to enter nearby populations. We compared ®tness components of wild Cucurbita pepo from Arkansas, USA, with wild±crop hybrids derived from yellow squash (a cultivar of C. pepo with transgenic resistance to two viruses...
At least 14 ascorbate oxidase (AO) isoenzymes with isoelectric points in the range of pH 3 /10 have been identified and their expression profile studied in various Cucurbitaceae tissues and during development and ripening of melon fruit (Cucumis melo L. var. reticulatus). At least four acidic AO isoenzymes were mainly located in the apoplastic fraction, whereas 10 basic AO isoenzymes were found...
selection of an appropriate model is important for quantifying response of germination rate to temperature and determination of cardinal temperatures. this study was done to evaluate different nonlinear regression models to describe response of germination rate to temperature in medicinal pumpkin, borago and black cumin. the regression models were dent-like, segmented, beta, curvilinear, quadra...
Microorganisms are ubiquitous and thought to regulate host populations. Although microorganisms can be pathogenic and affect components of fitness, few studies have examined their effects on wild plant populations. As individual traits might not contribute equally to changes in population growth rate, it is essential to examine the entire life cycle to determine how microorganisms affect host p...
The jasmonates are well studied in the context of plant defence but increasingly are also recognised as playing roles in development. In many systems, jasmonates antagonise the effects of cytokinins. The aim of the present work was to elucidate interactions between methyl jasmonate and cytokinin (benzyladenine) in regulating growth of zucchini (Cucurbita pepo L., cv. Cocozelle, var. Tripolis) c...
We monitored pollen-mediated transgene dissemination from commercial transgenic squash CZW-3 into its wild relative Cucurbita pepo ssp. ovifera var. texana (C. texana). Transgenic squash CZW-3 expresses the neomycin phosphotransferase II (nptII) gene and the coat protein (CP) genes of Cucumber mosaic virus (CMV), Zucchini yellow mosaic virus (ZYMV), and Watermelon mosaic virus (WMV); thereby, i...
We compared some fitness components of the wild squash species Cucurbita pepo spp. ovifera var. texana (C. texana) and three generations of hybrids (F1, BC1, and BC2) between C. texana and commercial transgenic squash CZW-3 over three consecutive years under field conditions of low (LDP) and high disease pressure (HDP) by Cucumber mosaic virus (CMV), Zucchini yellow mosaic virus (ZYMV) and Wate...
