Lipases of germinating jojoba seeds efficiently hydrolyze triacylglycerols and wax esters and display wax ester-synthesizing activity BMC Plant Biol. (IF 3.497) Pub Date : 2021-01-19 Adam Kawiński; Magdalena Miklaszewska; Szymon Stelter; Bartosz Głąb; Antoni Banaś
Simmondsia chinensis (jojoba) is the only plant known to store wax esters instead of triacylglycerols in its seeds. Wax esters are composed of very-long-chain monounsaturated fatty acids and fatty alcohols and constitute up to 60% of the jojoba seed weight. During jojoba germination, the first step of wax ester mobilization is catalyzed by lipases. To date, none of the jojoba lipase-encoding genes

Transcriptome profiling reveals the effects of drought tolerance in Giant Juncao BMC Plant Biol. (IF 3.497) Pub Date : 2021-01-04 Jing Zhou; Siqi Chen; Wenjiao Shi; Rakefet David-Schwartz; Sutao Li; Fulin Yang; Zhanxi Lin
Giant Juncao is often used as feed for livestock because of its huge biomass. However, drought stress reduces forage production by affecting the normal growth and development of plants. Therefore, investigating the molecular mechanisms of drought tolerance will provide important information for the improvement of drought tolerance in this grass. A total of 144.96 Gb of clean data was generated and

Dynamics of limited neoplastic growth on Pongamia pinnata (L.) (Fabaceae) leaf, induced by Aceria pongamiae (Acari: Eriophyidae) BMC Plant Biol. (IF 3.497) Pub Date : 2021-01-02 P. P. Anand; N. Ramani
Galls or the neoplastic growth on plants result from a complex type of interaction between the inducers (Acari, Insects, Microbes and Nematodes) and plants. The present study sheds light on the gall inducing habit of a highly host specific eriophyid mite, Aceria pongamiae, on the leaves of Pongamia pinnata leading to the production of abnormal pouch like outgrowths on the adaxial and abaxial surfaces

Transcriptome analysis and differential gene expression profiling of two contrasting quinoa genotypes in response to salt stress BMC Plant Biol. (IF 3.497) Pub Date : 2020-12-30 Pibiao Shi; Minfeng Gu
Soil salinity is one of the major abiotic stress factors that affect crop growth and yield, which seriously restricts the sustainable development of agriculture. Quinoa is considered as one of the most promising crops in the future for its high nutrition value and strong adaptability to extreme weather and soil conditions. However, the molecular mechanisms underlying the adaptive response to salinity

Assessment of differences in morphological and physiological leaf lodging characteristics between two cultivars of Hippeastrum rutilum BMC Plant Biol. (IF 3.497) Pub Date : 2020-12-14 Zhenjie Shi; Qianjiao Zheng; Xiaoyang Sun; Fuchun Xie; Jian Zhao; Gaoyun Zhang; Wei Zhao; Zhixin Guo; Ariuka Ariunzul; Shah Fahad; Muhammad Adnan; Dong Qin; Shah Saud; Chen Yajun
Environmental lodging stress, which is a result of numerous factors, is characterized by uncertainty. However, several studies related to lodging in cereal crops have reported that lodging in the Hippeastrum rutilum environment is very rare. Hippeastrum rutilum is a garden flower with high ornamental value and abundant germplasm resources. Under past cultivation practices, it was found that the plant

Nutraceuticals, phytochemicals, and radical quenching ability of selected drought-tolerant advance lines of vegetable amaranth BMC Plant Biol. (IF 3.497) Pub Date : 2020-12-14 Umakanta Sarker; Shinya Oba
Vegetable amaranth is a source of natural phytopigments and functional components of the commercial food industry for sustainable health benefits across the globe. It is guessed that recently identified amaranth (drought-tolerant) genotypes may contain ample phytopigments and phytochemicals suitable to extract juice as drinks. Hence, phytopigments and phytochemicals content of amaranth were assessed

Comparative proteomic analysis reveals novel insights into the interaction between rice and Xanthomonas oryzae pv. oryzae BMC Plant Biol. (IF 3.497) Pub Date : 2020-12-14 Fan Zhang; Fan Zhang; Liyu Huang; Dan Zeng; Casiana Vera Cruz; Zhikang Li; Yongli Zhou
Bacterial blight, which is caused by Xanthomonas oryzae pv. oryzae (Xoo), is a devastating rice disease worldwide. Rice introgression line H471, derived from the recurrent parent Huang-Hua-Zhan (HHZ) and the donor parent PSBRC28, exhibits broad-spectrum resistance to Xoo, including to the highly virulent Xoo strain PXO99A, whereas its parents are susceptible to PXO99A. To characterize the responses

SlGT11 controls floral organ patterning and floral determinacy in tomato BMC Plant Biol. (IF 3.497) Pub Date : 2020-12-14 Liling Yang; Shilian Qi; Arfa Touqeer; Haiyang Li; Xiaolan Zhang; Xiaofeng Liu; Shuang Wu
Flower development directly affects fruit production in tomato. Despite the framework mediated by ABC genes have been established in Arabidopsis, the spatiotemporal precision of floral development in tomato has not been well examined. Here, we analyzed a novel tomato stamenless like flower (slf) mutant in which the development of stamens and carpels is disturbed, with carpelloid structure formed in

Cloning of long sterile lemma (lsl2), a single recessive gene that regulates spike germination in rice (Oryza sativa L.) BMC Plant Biol. (IF 3.497) Pub Date : 2020-12-11 Dewei Yang; Niqing He; Xianghua Zheng; Yanmei Zhen; Zhenxin Xie; Chaoping Cheng; Fenghuang Huang
Rice is a typical monocotyledonous plant and an important cereal crop. The structural units of rice flowers are spikelets and florets, and floral organ development and spike germination affect rice reproduction and yield. In this study, we identified a novel long sterile lemma (lsl2) mutant from an EMS population. First, we mapped the lsl2 gene between the markers Indel7–22 and Indel7–27, which encompasses

Genome-wide identification and expression analysis of the CLC gene family in pomegranate (Punica granatum) reveals its roles in salt resistance BMC Plant Biol. (IF 3.497) Pub Date : 2020-12-11 Cuiyu Liu; Yujie Zhao; Xueqing Zhao; Jianmei Dong; Zhaohe Yuan
Pomegranate (Punica granatum L.) is an important commercial fruit tree, with moderate tolerance to salinity. The balance of Cl− and other anions in pomegranate tissues are affected by salinity, however, the accumulation patterns of anions are poorly understood. The chloride channel (CLC) gene family is involved in conducting Cl−, NO3−, HCO3− and I−, but its characteristics have not been reported on
