Crocus sativus (saffron) is a globally autumn-flowering plant, and its stigmas are the most expensive spice and valuable herb medicine. Crocus specialized metabolites, crocins, are biosynthesized in distant species, Gardenia (eudicot) and Crocus (monocot), and the evolution of crocin biosynthesis remains poorly understood. With the chromosome-level Crocus genome assembly, we revealed that two rounds of lineage-specific whole genome triplication occurred, contributing important roles in the production of carotenoids and apocarotenoids. According to the kingdom-wide identification, phylogenetic analysis, and functional assays of carotenoid cleavage dioxygenases (CCDs), we deduced that the duplication, site positive selection, and neofunctionalization of Crocus-specific CCD2 from CCD1.members are responsible for the crocin biosynthesis. In addition, site mutation of CsCCD2 revealed the key amino acids, including I1.3, L1.6, R1.1. E1.1. T259, and S292 related to the catalytic activity of zeaxanthin cleavage. Our study provides important insights into the origin and evolution of plant specialized metabolites, which are derived by duplication events of biosynthetic genes.

＜正＞Objective:The purpose of this research was to determine the effectiveness of resistance training in attenuating bone loss in hindlimb unloading rats undergoing a resistance training program for a period of 8 weeks. Methods:Forty male Wistar rats were divided randomly into four groups:an age-matched control group（C,n=1.）, a hindlimb unloading group（HU,n=1.）,a hindlimb unloading + stand group（HU+S,n=1.）,and a hindlimb unloading + resistance-training group（HU+RT,n=1.）.In HU+RT,1. rats were resistance trained for 8 *** resistance-training protocol was performed with 4 sets of 1. repetitions 5 days/week using 65%to 75%of one repetition maximum（maximum lifted weight） measured every 2 *** the end of 8 week resistance training, bone mineral density（BMD） and biomechanical properties of the femur were measured by Micro CT and three point bending test ***:Before the resistance training period,all the groups had similar repetition maximums However,at the end of the resistance training period,the repetition maximum in C and HU+RT was approximately 3-fold the body weight more than that in HU and HU+*** significant differences were observed for any of the bone parameters when comparing HU and HU+S rats.C and HU+RT rats had higher trabecular BMD than HU and HU+S *** Thickness（***） was greater in HU+RT than that in HU+***,no significant differences in BMD of cortical bone area were detected among all the groups in the femur *** maximal load and stiffness of the femur midshaft of rats in HU+RT were significantly higher than that in HU,while lower than that in ***:These results demonstrate that the resistance training can counter bone loss completely and mitigate the bone strength reduction caused by simulated weightlessness by hindlimb unloading.

Reasonable nitrogen(N) application is a promising strategy for reducing crop cadmium(Cd) toxicity. However, the specific form of N and the required amount that affect Cd tolerance and accumulation in rice remain unclear. This study explored the influence of different N-fertilizer forms(NH_(4)NO_(3), NH_4Cl, and KNO_(3)) and dosages on Cd tolerance and uptake in Cd-stressed N-sensitive and N-insensitive indica rice accessions. The results indicated that the Cd tolerance of N-sensitive indica accessions is more robust than that of N-insensitive ones. Furthermore, the shoot Cd content and Cd translocation rate in both N-sensitive and N-insensitive indica accessions decreased with an appropriate supply of NH_(4)NO_(3) and NH_4Cl, whereas they were comparable or slightly increased with increased KNO_(3). Unfortunately, we did not find significant and regular differences in Cd accumulation or translocation between N-sensitive and N-insensitive rice accessions. Consistent with the reduction of shoot Cd content, the addition of NH_(4)NO_(3) and NH_4Cl also inhibited the instantaneous root Cd^(2+) uptake. The expression changes of Cd transport-related genes under different N forms and dosages suggested that the decreased shoot Cd content, caused by the increased supply of NH_(4)NO_(3) and NH_4Cl, is likely achieved by reducing the transcription of OsNRAMP1.and OsIRT1. In summary, our findings reveal that an appropriate supply of NH_(4)NO_(3) and NH_4Cl could reduce Cd uptake and transport in rice seedlings, suggesting that rational N management could reduce the Cd risk in rice production.
