Abstract:
... China is the largest rice-producing country, but the genomic landscape of rice diversity has not yet been clarified. In this study, we re-sequence 1070 rice varieties collected from China (400) and other regions in Asia (670). Among the six major rice groups (aus, indica-I, indica-II, aromatic, temperate japonica, and tropical japonica), almost all Chinese varieties belong to the indica-II or temp ...

Abstract:
... Perennial herbaceous plants in seasonal temperate climates must form belowground storage organs to contain carbohydrates for seasonal regrowth and to mitigate disturbance and damage. The factors that dictate the size and turnover of these organs are still little understood. According to the Integrator–Splitter Hypothesis, storage organ persistence decreases with greater moisture and nutrient avail ...

Abstract:
... The effects of container type on plant growth, yield and production cost of seed potatoes were investigated. Potato cultivars ‘Saebong’, ‘Geumsun’ (early-maturing) and ‘Haryeong’ (mid-maturing) were grown in four types of plant container: small (25 cm × 25 cm × 19 cm, L × W × H), medium (63 cm × 22 cm × 15 cm) and large (53 cm × 37 cm × 19 cm) plastic boxes and a styrofoam bed (100 cm × 52 cm × 31 ...

Abstract:
... Heading date determines the seasonal and regional adaptation of rice (Oryza sativa L.) varieties and is mainly controlled by photoperiod sensitivity (PS). The core heading date genes Hd1, Ghd7, DTH8, and PRR37 act synergistically in regulating the PS. In this study, we systematically analyze the heading date, PS, and agronomic traits of eight homozygous lines with various combinations of Hd1, Ghd7 ...

Abstract:
... Plant heterotrimeric G proteins have been shown to regulate the size of various organs. There are three types of Gγ subunits in plants: type A, consisting of a canonical Gγ domain; type B, possessing a plant-specific domain at the N-terminus of the Gγ domain; and type C, possessing a plant-specific domain at the C-terminal of the Gγ domain. There is one type A, one type B, and three type C of the ...

Abstract:
... PREMISE: Tip‐to‐base conduit widening is considered a key mechanism that enables vascular plants to grow tall by decreasing the hydraulic resistance imposed by increasing height. Widening of hydraulic anatomy (larger conducting elements toward the base of the vascular system) minimizes gradients in leaf‐specific hydraulic conductance with plant height, allowing uniform photosynthesis across the cr ...

Abstract:
... Physalis angulata L. is an American species with edible fruits that stands out for having high nutritional and pharmaceutical value. The species is found in almost the entire Brazilian territory but the consumption of its fruits is not widespread. The aim of this work was to evaluate the existence of heterosis and heterobeltiosis for morphoagronomic descriptors, to estimate correlations, and to se ...

Abstract:
... Techniques to increase grain production such as nitrogen fertilization and plant growth regulators are essential to enable and enhance rice yield. Therefore, our goal was to evaluate the effect of nitrogen fertilization and application of trinexapac-ethyl on vegetative and reproductive traits of upland rice. Experiments were established in Registro, Brasil during the 2011 and 2014 growing seasons ...

Abstract:
... This study investigated the effects of daily light integral (DLI) on the photosynthesis, growth, and flowering of Veronica rotunda var. subintegra and V. longifolia. Six-week-old seedlings with four or five nodes were grown under five average DLI levels (3.6, 6.6, 8.1, 14.7, and 18.3 mol m⁻² d⁻¹) in a greenhouse. Both species grown under DLI conditions of over 8.1 mol m⁻² d⁻¹ showed a lower maximu ...

Abstract:
... SAR parameters have been used many times to characterize crops. However, it was found that the scattering mechanisms derived from quad-pol SAR were different from that of the dual-pol SAR data. The objective of this study is to better understand the scattering mechanism of the maize field to dual-pol (VV, VH) SAR data and propose a new radar vegetation index to improve the inversion accuracy of th ...

Abstract:
... Precise reconstruction of the morphological structure of the soybean canopy and acquisition of plant traits have great theoretical significance and practical value for soybean variety selection, scientific cultivation, and fine management. Since it is difficult to obtain all-around information on living plants with traditional single or binocular machine vision, this paper proposes a three-dimensi ...

Abstract:
... Point cloud segmentation is essential for studying the 3D spatial characteristics of plants. Notably, the segmentation accuracy greatly impacts subsequent 3D plant phenotypes extraction and 3D plant reconstruction. Automated segmentation approaches for plant point clouds are a bottleneck in achieving big data processing of 3D plant phenotypes. Using maize as a representative crop, this study devel ...

Abstract:
... Foxtail millet (Setaria italica) is an ideal model of genetic system for functional genomics of the Panicoideae crop. Identification of QTL responsible for morpho-agronomic and yield-related traits facilitates dissection of genetic control and breeding in cereal crops. Here, based on a Yugu1 × Longgu7 RIL population and genome-wide resequencing data, an updated linkage map harboring 2297 bin and 7 ...

Abstract:
... Tan spot (TS), caused by the fugus Pyrenophora tritici-repentis (Ptr), has gained significant importance in the last few years, thereby representing a threat to wheat production in all major wheat-growing regions, including Tunisia. In this context, we evaluated a Mediterranean collection of 549 durum wheat accessions under field conditions for resistance to Ptr over two cropping seasons in Jendou ...

Abstract:
... Agriculture practices in monocropping need to become more sustainable and one of the ways to achieve this is to reintroduce intercropping. However, quantitative data to evaluate plant growth in intercropping systems are still lacking. Unmanned aerial vehicles (UAV) have the potential to become a state-of-the-art technique for the automatic estimation of plant growth. Individual plant height is an ...

Abstract:
... Resistance to lodging, an important problem in rice production, has three types: low plant height, strong culm, and high strength of the lower part of the plant. The determinants of strength of the lower part remains unclear, compared with plant height and culm strength. This study identified a new genetic factor involved in the strength of the lower part, as assessed by pushing resistance, using ...

The 2,4-Diacetylphloroglucinol (2,4-DAPG) and phenazine (PCA)-producing Pseudomonas inhibit wheat pathogens’ development, but the relationship between communities of pathogens and genotypes of these bacteria has been little studied. Relationships between wheat crown fungi associated with the presence of 2,4-DAPG and PCA-producing pseudomonads were evaluated in four commercial wheat crops located i ...
