Leaf development in two-row spring barley under long-day and short-day field conditions

Reproduction of Dugesia tigrina under short-day and long-day conditions at different temperatures. I. Sexually derived individuals.

Five successive generations of asexually derived populations of D. tigrina and their sexually derived parental population were reared under each of six combinations of 20, 23 and 26 °C with 12 and 16 h of daylight. Asexual and sexual reproduction were recorded for each population. Peaks of asexual reproduction occurred increasingly earlier in consecutive generations to finally disappear or occu...

در این پژوهش مسئله واگذاری ترافیک را از دید سیستم های دینامیکی فرمول بندی می کنیم.فرض کرده ایم که همه فاکتورهای وابسته در طول زمان ثابت باشند و تعادل کاربر را از طریق فرایند منظم روزبه روز پیگیری کنیم.دینامیک ترافیک توسط یک نگاشت بازگشتی نشان داده می شود که تکامل سیستم در طول زمان را نشان می دهد.پایداری تعادل و دامنه جذب را توسط مطالعه ویژگی های توپولوژیکی تکامل سیستم تجزیه و تحلیل می کنیم.پاید...

Relation between the Development of Root System and Shoot under Long- and Short-day Illumination.

GmCOL1a and GmCOL1b Function as Flowering Repressors in Soybean Under Long-Day Conditions.

CONSTANS (CO) has a central role in the photoperiod response mechanism in Arabidopsis. However, the functions of legume CO genes in controlling flowering remain unknown. Here, we analyze the expression patterns of E1, E2 and GmCOL1a/1b using near-isogenic lines (NILs), and we further analyze flowering-related genes in gmcol1b mutants and GmCOL1a-overexpressing plants. Our data showed that both ...

Disruption of fumarylacetoacetate hydrolase causes spontaneous cell death under short-day conditions in Arabidopsis.

Fumarylacetoacetate hydrolase (FAH) hydrolyzes fumarylacetoacetate to fumarate and acetoacetate, the final step in the tyrosine (Tyr) degradation pathway that is essential to animals. Deficiency of FAH in animals results in an inborn lethal disorder. However, the role for the Tyr degradation pathway in plants remains to be elucidated. In this study, we isolated an Arabidopsis (Arabidopsis thali...
